SmartCEMS® GHG

GHG emissions from wastewater handling

Broadly, wastewater systems contribute to Greenhouses gases (GHG) emissions not only through their significant consumption of grid electricity in most cases, but also through direct emissions of nitrous oxide (N2O) and methane (CH4). These are often called ‘fugitive’ gases because they escape from the collection and treatment systems.

CH4 emission: Wastewater contains organics, which can be biologically converted to CH4 in the absence of oxygen (i.e., under anaerobic conditions). In some parts of wastewater collection and treatment systems, anaerobic conditions prevail, leading to the formation of CH4 and its subsequent emission into the atmosphere.

N2O emission: Wastewater contains nitrogen, which needs to be removed to avoid nutrient enrichment of receiving waters. Biological nitrogen removal has been implemented at most large wastewater treatment plants in Australia. N2O is either an intermediate reaction or a by-product of the key biological reactions involved. Therefore, N2O is formed in, and could be emitted from, wastewater treatment plants.

The indirect emissions are expected to decrease substantially in the coming decade, due to both the increased recovery of energy from wastewater (biogas from anaerobic digestion) and improved efficiency of electrical energy use for wastewater treatment.

Furthermore, the current trend is towards increasing renewable energy supply, with resultant lower emission factors. Therefore, it is foreseeable that direct emissions might in future dominate the GHG profile of many wastewater treatment plants. Indeed, for some treatment plant in Australia, this may already be true.

Actual methane and nitrous oxide emissions associated with wastewater handling vary significantly, depending on the type of system and a range of operating factors.

Emissions can make up a substantial portion of direct GHG emissions reported as part of the total for water utilities that serve urban areas. The existing GHG reporting (NGER) system in Australia does not make provision for measurements or estimates of actual direct emissions of nitrous oxide and methane emissions from wastewater handling.

Understanding of greenhouse gas emissions related to wastewater handling has improved a lot in the last ten years, thanks to the efforts of researchers and the water industry, including significant contributions from Australia.

PROCEAS® in GH2 Plants

Process Control and Purity in GH2 Plants

The realization of the importance of shifting from fossil fuels, both for environmental and energy security reasons, makes the use of green hydrogen extremely pertinent, as one of several potential low-carbon fuels that could take the place of fossil hydrocarbons in GH2 Plants.

To maintain safe operation, optimise the power to hydrogen conversion, and maximize the quality and purity of the produced hydrogen; the green hydrogen production process relies on measuring multiple parameters as extensively as possible and using the resulting data to inform GH2 Plants Operators.

AquaGas online analysers are suited to a large range of applications within the GH2 Plants providing real time gas stream composition at key locations:

  • Upstream or downstream of the electrolyser
  • At mixing stations or injection points
  • Along the natural gas pipeline
  • At customer sites just upstream of burners

When used to their full extent, the expanded capabilities offered by accurate and reliable analysers can bring real benefits by optimising efficiency and safety, and providing fast access to detailed data and an accurate real time overview of the operating conditions.

Committed to a better environment, AquaGas Pty Ltd is proud to supply and support a broad product range featuring a line of analysers and gas detection systems tailored to the GH2 industry. Already selected by several of the main actors in the green hydrogen industry, AquaGas analysers offer exclusive features implemented to fullfil the needs of today’s Green Hydrogen production.

The ProCeas® multigas analyser for GH2 applications

For process control and purity assessment at GH2 Plants, the ProCeas® uses the patented OFCEAS technology, based on extractive absorption spectroscopy. This laser-based technology is able to measure gases down to sub-ppb levels of concentration, with an unforeseen quality of measurement in terms of accuracy and repeatability. The ProCeas® samples the gas at low pressure, with an internal pressure below 100 mbar absolute. This dilution reduces the volume needed to get a correct measurement and optimizes the response time of the analyser. In the end the system requires small samples of hydrogen.

Additionally, ProCeas® has an integrated auto calibration of the measurement system, allowing no drift under normal use of the instrument. ProCeas® can analyse a large range of impurities with limited service and maintenance costs.

The ProCeas® Hydrogen key features include:

  • Highly sensitive
  • Low detection level (sub-ppb)
  • Complete pre-calibrated laser infra-red spectrometer
  • No Zero drift and no Span drift – No daily calibration required
  • No nitrogen, zero air, purge or other carrier gas
  • ProCeas® H2 Purity for ISO compliance monitoring (H2S, CO, CO2, CH4, O2, NH3, H2O, HCHO, etc.)
  • Process control ProCeas® H2 trace analyser (H2 and O2)
  • Limited volume of sample needed for an analysis

The field of application for fast and precise online analysers in the GH2 Plants is considerably exhaustive. Here below are two cases where online measurement of H2 and O2 is critical.

The ProCeas® H2 trace gas analyser

Ensure safe Electrolyse with the ProCeas® H2

At their simplest level, electrolysers produce oxygen at the anode and hydrogen at the cathode. However, many reactions in the electrolyser can cause small concentrations of oxygen to build up in the hydrogen stream and hydrogen to build up in the oxygen. This is a fault condition and must be detected by appropriate instruments that can be used as part of an automated safety system that can initiate actions in the event of an oxy-fuel gas mixing alarm being activated.

With a detection limit down to 3ppm for the H2 and 1ppm for the O2, The ProCeas® hydrogen is perfectly suited to O2 and H2 trace gas monitoring and consequently can be used to measure both traces of hydrogen in the oxygen stream and traces of oxygen in the hydrogen stream.

The ProCeas® H2 Purity

Keeping production up to standard with the ProCeas® H2 Purity

As a multi-stage process, green hydrogen production requires accurate measurement of a variety of parameters to ensure safe and efficient operation. ISO14687-2 stipulates the impurities that need to be measured and their respective limits throughout the various stages of the production process to help maintain control and avoid potential issues that could affect efficiency or safety.

GREEN HYDROGEN [GH2]

Green hydrogen (GH2) is hydrogen that is  generated by renewable energy or from low-carbon power. One of the paths to near-total decarbonization is supplying the whole energy system using clean renewable power combined with low-carbon fuels. Hydrogen is an important component of global efforts around the world to de-carbonise the energy sector.

The realization of the importance of shifting from fossil fuels, both for environmental and energy security reasons, makes the use of green hydrogen extremely pertinent, as one of several potential low-carbon fuels that could take the place of fossil hydrocarbons.

The affordability of renewable energy resources as well as the developments in electrolysis technology increase the potential of “green hydrogen” as a clean and sustainable form of fuel production. The global hydrogen production is set to more than double in the decade between 2020 and 2030, from 70 million tons to 170 tons. Projections beyond 2030 point to a further increase as production technologies become more efficient and production costs fall.

GH2 is a versatile form of energy

Green hydrogen produced by the electrolysis of water may be used to decarbonize sectors which are hard to power from any energy other than fossil fuels, such as steel and cement production, and thus help to limit climate change.

Green hydrogen can be blended into existing natural gas pipelines, and used to produce green ammonia, the main constituent of fertilizer production. Green hydrogen can transform into many different types of energy, including electric and synthetic gas for heating, powering electronics, fuelling vehicles. Right now, the most common uses of green hydrogen energy are oil refining, steel manufacturing, ammonia production and food processing.

Hydrogen is abundant, it’s easier to store and provides a better efficiency than other energy sources.

Producing GH2

Key to the production of green hydrogen is the use of an electrolyser to split water into hydrogen and oxygen while renewable sources such as wind, solar or hydroelectric power generate the necessary power for the electrolysis process. Carrying out large scale electrolysis as needed to provide the quantities of hydrogen to overcome the growing energy demand presents several challenges.

It is obviously imperative that the entire production chain is monitored continuously for process control and safety. That includes maintaining optimal electrolyser performance, as well as avoiding potentially explosive leaks. Hydrogen affects the BTU value of the natural gas, therefore measuring the amount of hydrogen present in natural gas is critical for utility companies, industrials, pipeline distribution network, and of course the end user.

GH2 process monitoring and control

Plant performance, energy consumption, production rates, purity and storage are among the key performance indicators (KPI) for hydrogen production which require visibility to ensure efficient production.

To maintain safe operation, optimise the power to hydrogen conversion, and maximize the quality and purity of the produced hydrogen; the green hydrogen production process relies on measuring multiple parameters as extensively as possible and using the resulting data to inform Plant Operators.

Today’s online measurement technologies provide greater accuracy, range and depth of information that can be used to assess both process performance and the status of the plant, especially important in preventing unexpected problems such as faults or failures in safety-critical applications.

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.
