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.

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.

*Optical Feedback Cavity Enhanced Absorption Spectroscopy: technology developed and patented by the University Joseph Fourier (France), coupled to a Low Pressure Sampling (100 mbar absolute) developed and patented worldwide by AP2E, for the on-line analysis of different gases. By the end of 2010, after two years of R & D studies, the AP2E ProCeas® was the award recipient of the USA “R & D 100” which rewards the 100 most innovative global technologies of the year.
