Tank Headspace Monitoring Systems – THMS

Applications

in the Oil and Gas industry.

Water treatment plant in refineries and other oil and gas processes requires the use of tank for storage purposes and as part of the wastewater management plan. The composition of the air confined in the tank headspace provides a good indication of the level of contamination in the wastewater influents. Monitoring gas in tank headspaces also becomes mandatory when it comes to managing oils contaminated water. Explosion risks but also the corrosion and degradation factor are controlled with the blanketing whose automation can largely be optimised by the online measurement of gas concentrations in the headspace. Moreover there is a large number of compounds that will  adduce plant operators detailed information with regards to filtration and decantation processes.

Tank Blanketing Automation

Tank blanketing is the process of filling the headspace in storage vessels and reactors with an inert gas, usually to protect its contents from exploding, degrade but also to protect equipment from corrosion. As oxygen and moisture in the air can be undesired in numerous processes and applications, blanketing is done in a wide range of industries, varying from petrochemicals to food and beverage, pharmaceutical to pure water. Inerting is done for similar reasons but is not limited to storage tanks and reactors only. Any confined space can be sparged with an inert gas to create the desired atmosphere. This ranges from packing food under protective atmosphere to increase shelf life to lowering the oxygen concentration in rooms where welding takes place to reduce risk of fire.

Risks Management

Wrongly engineered or poorly maintained blanketing systems may lead to serious incidents, degraded plant operations and pollution events. A malfunctioning may cause the tank to implode or causes the leaking of air into the tank, which, as mentioned, can have consequences with regard to product quality and, depending on the stored product, can seriously increase risk of explosion.

One way to increase safety and reduce the use of blanketing gas (nitrogen, air…) simultaneously is to control inertisation as a function of gas concentration in the headspace. Depending on the product and the reason for blanketing and inerting, there are tolerances when it comes down to the maximum allowable oxygen, VOCs or other combustibles concentration. Certain monomers require zero percent oxygen to prevent polymerization. Others require a small amount of oxygen for the same reason. In the case of explosion protection, the oxygen concentration does not necessarily need to be zero. In fact for all solvents a so called limiting oxygen concentration exists. Below this concentration there is no risk of explosion. It is obvious that controlling the tank headspace purge based on the concentration will seriously cut nitrogen or other blanketing gas costs. Furthermore the measurement of gas concentrations in the tank headspace provides an important safety parameter.   Thresholds such as Limiting Oxygen Concentration (LOC), Maximum Oxygen Concentration (MOC), Lower Explosive Limit (LEL) indicate application and gas specific limits in terms of concentration.

For example, two threshold values are established for the oxygen concentration in the tank headspace, well below the Limiting Oxygen Concentration; the Lower Intervention Level and the Upper Intervention Level. These two threshold values are the set-points that control the purging sequences. The moment the oxygen concentration reaches the Lower Intervention Limit, the nitrogen flow is intermittent. Purging of the vessel is resumed when the upper intervention limit is exceeded. This means that the inerting system keeps the consumption of nitrogen minimal while safe operation is ensured.

Analyser solutions

Depending on individual process conditions and solvent; O2, H2O and LEL are usually the main parameters of interest. However when odour control is implemented NH3, H2S and VOCs can be added to the monitored parameters.

To meet the needs of the waste recycling facilities, AquaGas offers a unique fully automatic solution for realtime measurement of gas concentrations in Tank Headspaces. AquaGas THMS features the association of a MAMOS multigas analyser fitted with a combination of 9 gas proprietary measuring cells with a field proven, robust and dedicated Exproof sampling train. The system can be multiplexed for controlling up to 4 tank headspaces. Both the gas sampling probe located at the top of the tank and the sample line are temperature controlled above the gas dew point. Depending on the application, the gas can also be fitted with the optional backflush, temperature sensor, insitu filter… The onboard PLC offers a large panel of IOs as required to handle blanketing regulator, breathing valve, safety relief valve…

The THMS is integrated in Australia by AquaGas for continuous and simultaneous measurement of VOC, NH3, CO, CO2, LEL, CxHy, H2S and O2 inside tank headspaces.

Advantages of AquaGas THMS

The AquaGas THMS is a cost efficient and safe solution available in a compact wall mount IP56 enclosure that totally eliminates the need for multiple sensors and probes. The sampling probe can be mounted directly into the vessel or blanketing gas discharge piping and is rated for high dust, moisture or solvents loads. A retractable filter assembly allows cleaning of the sampling probe without the need for dismounting the probe from its matching flange. Zero calibration is performed automatically on a daily basis while span gas calibration is only required quarterly. In very critical applications, the system can be equipped with redundant probes and or sensors for additional safety and self check purposes. Compared to traditional analyser technology, the AquaGas THMS is available at only a fraction of the costs. The most valued perceived benefit however is the significant increase of safety, enormous savings on tank maintenance as well as the optimised process operations.

CEMS and process gas analyser

 

A new approach to continuous gas monitoring

The Mamos is a high quality stationary monitoring system for the measurement of up to 6 gases as well as gas temperature, ambiant and differential pressures (Gas Flow) in a large field of applications.

Designed to optimise performance/price ratio, small in size and yet very skilful analyser, the Mamos is the field proven alternative for large, intricate Continuous Emissions Monitoring Systems, as it does not fall behind them concerning functionality, abilities, reliability and is far ahead in terms of expenses.

AquaGas Multigas CEMS

Online monitoring made easy

Fully automated and packed with exclusive features, the Mamos concept enlarges monitoring possibilities and respond to the today’s demands in terms of accuracy, reliability and flexibility. Each analyser is supplied with its own sampling system. The entire system is mounted on a wall mount plate and designed for installation in industrial settings and rough environment. It has a modular construction, and offer a large panel of add-ons to match site specific application requirements. The Mamos minimises the installation and ongoing operation cost until now required to fulfil your monitoring needs.

MAMOS-Multigas-analyser-CEMS-features

Multigas

Depending of the gas matrix and components to be analysed, the Mamos can be fitted with up to 6 different sensors. The combination of technologies (NDIR, TCD, PID, Electrochemical) and the addition of separate gas channels into the same instrument empower flexibility in multigas applications. A unique feature is to allocate a gas channel to sensible sensors. Its design ensures the cells have a limited exposure to gases and therefore extends considerably their respective life-time.

Process gas and emissions monitoring in combustion plants, boilers, syngas, biogas, waste recycling facilities and associated filtration systems are typical applications for multiple gas channels configuration.

In Biogas, the primary gas channel holds the CO2, CH4, Osensors while an additional separate gas channel is allocated to sensible Electrochemical sensors, H2S for example. The two NDIR gas channels can then be used for CO and VOCs.

Applications and References

The ProCeas® and the LaserCEM® are based on the OFCEAS* measuring principle combined with a Low Pressure Sampling LPS (100 mbar absolute) developed and patented worldwide by AP2E (France), for the online analysis of several key gases in industrial, environmental and OH&S applications. It provides measurements with a very high spectral resolution in addition to an exclusive and powerful sampling method (no heated line nor treatment of samples) and an interference-free, fast and sensitive analysis, regardless of the matrix of the gas to be analysed.

With the environmental constraints, Oil companies are looking for optimum energy and environmental efficiency of their burners. Combined cycles boilers optimisation requires accurate simultaneous online monitoring of O2 and CO to ensure both compliance with standards and process control efficiency. The ProCeas, used to track real time the residual rate of O2 (less than 3%), ensures optimal combustion process automation. The accuracy of the measurement is a financial matter: according to the thermal performance of the burner, even a reduction of 0.1% of oxygen in excess represents millions of dollars of savings in the annual consumption of fuel.

SOx monitoring

SO2/SO3: AP2E also intends to enhance the approach aimed at combining environmental compliance and process optimisation, even if this seems less obvious to understand at first sight. If today SO2 is correctly measured, this does not fully reflect the sulphur emissions from combustion units subject to this requirement. In the presence of oxygen, SO2 does in effect form sulphur trioxide (SO3), a gas that is much more corrosive than SO2.

LaserCEM

Other chemical phenomena occur, particularly in denitrification (DeNOx), which in the presence of ammonia may lead both to an over-consumption of ammonia and to filter blockages. Therefore, not measuring SO3 entails the under estimation of sulphur emissions, and also additional maintenance costs and over-consumption of reagents. To have continuous and precise knowledge of the SO2 / SO3 couple enables the operator to choose the controlling conditions for limiting the formation of SO3 and its indirect costs.

Biogas

The processing of gases from biomass (biogas, bio-methane) remains a key step in industrial processes for producing various types of bio-energy, a manufacturing process that requires optimizing.

It is therefore imperative to have the ability to calculate the calorific value of these new gases and to be able to quantify the impurities present there, in order to reduce the risk of damage to facilities, to react quickly in case of malfunction, and to certify the quality of finished products. AP2E has installed several equipment units within the facilities of various players of the world of biogas around the world. The purpose is to analyse the CH4 and CO2 content, as well as the residual concentration of H2S. This is a major impurity which transforms into sulphuric acid in the presence of some moisture. It is a very corrosive acid; consequently it is destructive for the facilities and the engines that burn biogas or bio methane.

The ability to analyse in the same multiplexing equipment the H2S content (which varies according to the time of day) of the “raw biogas” at the exit of the casing serves to determine the use of this biogas and assess its composition and quality. Other compounds may also be monitored by adding specific laser sources, such as the water content, in order to control the efficiency of the condenser. AP2E is also currently studying the analysis of siloxane, another sore point for energy recovery.

Using a continuous analyser as a means of industrial control and economic optimization of production units is for the control of biogas quality. During the combined cycles of biogas generation, the absence of H2S is crucial. It is a major impurity and a source of engine breakage. However, conventional means of analysis have trouble distinguishing CH4 from H2S. Therefore, operators are forced to adopt an excessively prudent approach in the treatment stage with active carbon: it is changed even before it is totally saturated. With a continuous, accurate, and reliable analysis of the level of H2S in the exit of the adsorption bed, we can instead use it until its saturation point and reduce overall costs.

Tests conducted on a site with a valuation of 1 MW showed that the amortization of the analyser could be performed based on this single criterion of active coal consumption in less than a year. Indeed the cost of a monthly activated carbon charge is equivalent to AUD $65,000.

 

Indoor air quality

Fgas monitoring system

References: In 2010, AP2E won an important contract with the DCNS for air quality control equipment for the confined interiors of submarines (on-board crew safety).

In April 2015, European regulations included formaldehyde as a proven carcinogenic product (CMR). In 2014, the ProCeas was certified approved method by EXERA (measurement, control, and automation equipment) and the LNE (National laboratory of metrology and testing).

AP2E is already working in the confined air field (submarines) and is interested in the building sector.  This new classification impacts devices monitoring the exposure to workers or to the public of formaldehyde, Freon, Ethanol… present in the indoor air of industrial sites or sites hosting the public. The ProCeas® Formaldehyde continuously measures these changes with a minimum 10 ppm threshold (maximum 1%).

Food processing industry

The drying field is another good example of application where energy efficiency has to be kept in mind, especially when processing food powders. Water monitoring is useful for avoiding excessive energy consumption (adjust dryer load to obtain minimise the residual H2O content). Online monitoring of carbon monoxide (CO) answers safety concerns. When food powders are dehydrated, the conditions may be such that CO is generated in the dehydrator. Once conditions for generating CO are present, CO tends to increase its concentration very quickly. To keep the CO below potentially dangerous level, it is necessary to detect the first signs of CO which appear above the levels already present in the atmosphere. The ProCeas is actually in operation within ten drying towers in dry food production facilities and has been chosen as the most reliable monitoring equipment by companies leading food processing industry.

Engine emissions testing

The automobile engines sector also remains a major target. With the arrival of the new EURO VI standards since September 2014, manufacturers have been forced to measure many pollutants (NO, NO2, N2O, NH3, CO2, CH4, and ethanol).

ProCeas

Successful testing with ProCeas® was conducted around the world:

– NH3 at Renault and VOLVO (France)

– N2O at Volkswagen (Germany)

– NH3 at General Motors (USA)

– NH3, N2O, NO, NO2 at Sensor Inc. (USA)

In the USA with Sensors Inc. – (www.sensors-inc.com): in May 2012, AP2E signed a contract for supplying ProCeas® analysers for the real-time control of gas emissions of engine test benches in the automotive industry. Sensors Inc. is the leading American manufacturer of real-time testing equipment for gas emissions in the transportation industry. The new range of measuring instruments is marketed in the US under the name of SEMTECH LASAR and it consists of four modules (NH3, N2O, NO, and NO2), each capable of analysing three gases simultaneously.

Natural gas

To be used in the best conditions, so that it limits damage and maintenance of equipment, natural gas must be rid of impurities, especially hydrogen sulphide (H2S), which is very corrosive, and all traces of moisture. Current filtration systems run against, among other things, the problem of measuring residual traces of these impurities because no reliable continuous analysis system was available so far. Today the main players in the “Oil & Gas” market deem the ProCeas® as the most efficient natural gas analyser for continuously and simultaneously measuring traces of H2S (LoD under 50 ppb) and H2O (under 50 ppm), without interference, without any dependence vis-à-vis the constitution of the gas, and with response times under a few seconds

H2O, CO, CO2, and H2 rates

Praxair uses the ProCeas® as an online analyser of H2O, CO, CO2, and H2 rates, in a process for producing syngas from the gasification of coal, oil residue, pet coke, and biomass. This syngas is then used either as a source of energy in a heat and electricity combined cycle process or in a Fischer Tropsch process for producing second-generation bio-fuel. This process requires that the residual H2S generated by gasification have a value of less than 1 ppm to avoid the destruction of the polymerization catalysts.

CO, CO2, H2O, CH4, H2S, NH3 and H2

Midrex is a steel manufacturer that uses a gasification process similar to Praxair’s in order to cogenerate the electricity and heat needed in the manufacture of its steel. AP2E delivered to Midrex complete solutions that have enabled it on the one hand to measure the calorific value of these synthetic gases (by measuring CO, CO2, H2O, CH4, and H2) and also the presence of impurities such as H2S and NH3.

H2, H2O and Cl2

Today, the ProCeas® provides what no other infra-red laser technique could: the direct measurement of hydrogen (H2) and water (H2O) in chlorine (Cl2) without reagents or discharges, and interference-free. The ProCeas® performs measurements with a very high spectral resolution of very low concentrations (under a few ppm), with response times under a few seconds. This analyser also provides a control of the drying (H2O) in a chemical process at Arkema.

OFCEAS & Low Pressure Sampling

Continuous Emissions Monitoring and Process Control

Starting in 2012, AP2E launched the industrialisation of the ProCeas® and LaserCEM® product range, the continuous and multigas analysers using OFCEAS* patented laser spectrometry. This analyser range is based on several innovations, providing very high performance in terms of response time (less than a few seconds) and great accuracy of the analyses (wide dynamic range from ppb to %):

OFCEAS, CONTINUOUS INFRA-RED LASER SPECTROSCOPY TECHNOLOGY

The ProCeas® and the LaserCEM® are based on the OFCEAS coupled to a Low Pressure Sampling LPS (100 mbar absolute) developed and patented worldwide by AP2E (France), for the online analysis of several key gases in industrial, environmental and OH&S applications. It provides measurements with a very high spectral resolution in addition to an analysis system with a simplified sampling (no heated line nor treatment of samples) and an interference-free, fast and sensitive analysis, regardless of the matrix of the gas to be analysed.

ProCeas

The OFCEAS technology essentially differs from the CRDS (Cavity Ring Down Spectroscopy or Spectroscopy by resonance damping time) technology by its feedback principle: a part of the emitted radiation is returned from the chamber to the laser, enabling the tuning of the laser and the cavity resulting a resonance phenomenon. With a volume of only 15 cm3, the measuring cavity or cell is equipped with mirrors whose reflectivity exceeds 99.99%, providing an optical path between 1 and 10 km (approx. 10 meters in conventional technologies). The immediate consequence of this phenomenon is the identification of very intense absorption peaks with a very narrow spectral width. Given that the source used is a continuous laser, the system presents very high measurement stability: there is no zero drift and no need for new calibrations.

LOW-PRESSURE SAMPLING SYSTEM

The Low Pressure Sampling (LPS) System allows reducing the sample dew point (vapour pressure) to prevent the risk of condensation. The sampling method is achieved by the use of a sonic nozzle which allows reducing the sampling pressure down to 100 mbar. In these conditions the ambient temperature is almost always above the dew point eliminating the risk of condensation.

r4

  • No Sample heated line required to eliminate condensation: low power consumption, no related ongoing maintenance
  • True Direct Extractive CEMS/Process analyser (no dryer or scrubber)
  • No risk of absorption/desorption typical of high SO2/SO3 application
  • Low pressure accentuate the gas finger print
  • Cost effective multipoint monitoring
  • Standard system comply with ATEX standards

The integrity of the sample is therefore ensured. The very low airflow ensures a verylow response time and a minimal contamination of the system.

OFCEAS Detection limits

All these points enable to both increase the detection sensitivity and  simultaneously reduce the noise, which permits the detection of gases at very low levels of sensitivity (traces of H2S – LOD under 50 ppb, or traces of H2O – under 1 ppm).

ProCeas

Complete pre-calibrated multicomponent (H2S, CO, CO2, H2, H2O, HCl, HCN, HF, N2O, NH3, O2 and CH4) laser Infrared Spectrometer designed for online monitoring of combustion process, natural gas (LNG), pure gas (trace) and ambient air (trace).

 

LaserCEM

The LaserCEM is a complete pre-calibrated multi-component (NO, NO2, NOx, SO2, CO, HCl, CO2, H2O, H2S, NH3, N2O, COS, SO3, CH4, HF) laser Infrared Spectrometer designed for Continuous Emissions Monitoring and compliant to standard EN 15267-3 : 2008 and QAL 1 de EN 14181 . With the announcement of the continuous measurement of SO3 (sulphur trioxide) at the exit of combustion units, AP2E represents the link from an industrial point of view between regulatory measurements (EMC) and optimizing production processes. If SO2 is now properly measured, it does not fully reflect the sulphur emissions from combustion units subject to this requirement. In the presence of oxygen, SO2 does in effect form sulphur trioxide (SO3), a gas that is much more corrosive than SO2. And other chemical phenomena occur, particularly in de-nitrification (DeNOx), which in the presence of ammonia may lead both to an over-consumption of ammonia and to filter blockages. Not measuring SO3 entails the under estimation of sulphur emissions, and also additional maintenance costs and over-consumption of reagents. To have continuous and precise knowledge of the SO2 / SO3 couple enables the operator to choose the controlling conditions for limiting the formation of SO3 and its indirect costs.
