CO2 reporting and accounting

Flow metering will become necessary for fiscal purposes, custody transfer and compliance with future regulatory measurements. For each step of the CCUS network, accurate flow measurement allows for complete and precise reporting and the possibility of billing the captured carbon dioxide collected from different sources, transported via pipelines and stored or reused.

Process efficiency

Carbon capture processes require a high degree of efficiency to improve their economic and environmental attractiveness. The measurement of CO2 content after the capture process is essential for control and optimization purposes.

Quality control

Regardless of the destination of the captured CO2 (storage or utilization), it is important to control the quality of the gas and possible impurities that can have a negative influence on the later steps of the CCUS network and ensure protection of the environment.

Gas flow measurement for transfer and process applications

Carbon dioxide can be captured from different emission sources and then collected and transported via pipelines or ships for further handling steps like storage or utilization. Gas flow measurements are necessary at each transfer point to control the quantity of captured CO2 or the volume stored or transferred to other companies for utilization. Accurate gas metering allows for precise accounting to companies or calculation of CO2 taxes and credits based on regulations. Ultrasonic gas flow meters from SICK provide the reliable and precise data required to operate the CCUS chain. The FLOWSIC600 and FLOWSIC600-XT gas flow meters can take on any challenge – whether used as a stand-alone or system solution – and deliver optimal measurement performance. Gas flow meters from SICK provide the highest rated gas metering accuracy. Thanks to PowerIn Technology™, the FLOWSIC600-XT also ensures that measurements continue to be taken and data is stored even in the event of a power failure. The rugged design provides both fault-free and maintenance free systems. Due to the direct path layout, the signals are not reflected inside the device and are thus not affected by contamination. This results in long-term system stability and accuracy.

Reliable turnkey solution for CO2 metering

The FLOWSKID flow metering system is a full gas flow metering system. It is provided by SICK as a turnkey solution for transfer applications. The system is flexible in design and provides highly accurate measurement data. With FLOWSIC600 or FLOWSIC600-XT gas flow meters as the heart of the metering skid, system reliability can be assured. The metering skid can be customized with instrumentation including gas analyzers, gas chromatographs, and supervisory computers. It is manufactured according to ISO standards and is of the highest quality in line with the latest DIN, ANSI, and ASME standards. This means the system will fulfill local regulations and requirements.

Measurement of the concentration of captured CO2

CO2 is emitted from different industrial processes and can be captured with a dedicated unit placed before the release of the exhaust gas into the atmosphere. To control and optimize the efficiency of the capture process, the GM35 in-situ gas analyzer accurately measures CO2 directly in the gas flow without gas sampling. The reliability, precision and short response time of the GM35 offer a key advantage for efficient control loops. It can also measure H2O as well as temperature and pressure to complete the process control system. Continuous monitoring of CO2 concentration is also important when it comes to transfer for further handling and accounting.

Quality measurement: analysis of CO2 concentration and impurities in the captured CO2 gas matrix

Carbon capture processes produce a high concentrated gas with more than 90% CO2 by volume. However, the gas matrix also contains other components that can be considered as impurities. The measurement of these components is essential prior to later steps like transport, storage or utilization. Of course, some impurities can be corrosive or have an influence on conversion processes. Extractive analyzers from SICK ensure continuous monitoring of multiple components simultaneously with high accuracy to control and optimize CCUS processes. The most suitable analyzer can be selected depending on the application, the measuring conditions and the requested measuring parameters. Hot/wet extractive analyzers are perfect when several components are required, i.e. with a MCS200HW to measure CO2, H2O, HCl, SO2, CO, NOx, NH3 and O2, or a MCS300P HW for higher SO2, HCl or NOx concentrations. The GMS800 cold/dry extractive analyzer can be used for less corrosive applications and when only few components are required.

Greenhouse gas (GHG) control

EU Directive 2003/87/EC, which establishes a scheme for greenhouse gas emission allowance trading, requires proof of CO2 emissions of all CO2 sources in a power plant and other plants included within the Directive. The exact emitted concentration of CO2 can be difficult to calculate, which is why measurement in the exhaust duct is a desirable alternative. SICK has developed a unique solution for monitoring CO2 emissions directly and providing the uncertainty certifications for reporting and trading allowances based on the EU regulations. The GHG-Control CEMS solution combines the GM35 NDIR in-situ gas analyzer, the FLOWSIC100 ultrasonic gas flow measuring device, the MEAC GHG data acquisition system as well as engineering services to provide a complete measurement system, thereby eliminating the need for laborious calculation methods and saving time and money.

Space and protection for measurement and analysis technology

Container solutions are primarily used to protect the installed analyzer systems from extreme ambient conditions such as heat, cold, dust, wind, earthquakes and corrosive or explosive atmospheres. They also offer advantages for transport as well as on-site installation and maintenance. At the factory, everything is coordinated and pre-installed in the container in a clear manner. Each container can be equipped to fit individual customer requirements. The installation of transformers and UPS, extinguishing, climate and gas warning systems is possible, as is the implementation of sample point switching or complex redundancy and signal concepts.
