Efficiency maximization through optimal amine concentration
The separation of carbon dioxide plays a crucial role in the fight against climate change and in reducing greenhouse gas emissions. Scrubbers are of vital importance in the process of CO2-absorption. A key component in a scrubber is the washing liquid, whose monitoring is crucial. By constantly measuring the washing liquid, the performance for CO2-absorption can be maintained in the ideal range.
This optimizes the use of process fluids and minimizes operating costs. In this way, we combine ecological responsibility with economic efficiency. LiquiSonic® provides precise analysis and monitoring of the washing liquid through ultrasonic measurements with an accuracy of up to ± 0.05%.
The robust plug & play sensor design ensures a long service life of the system and reduces time-consuming laboratory measurements. Furthermore, the measuring system extends the lifespan of your process plant by reducing corrosion, which can occur due to overdosing.
Cost reduction through process optimization
For the effective operation of a carbon capture system, the precise determination of the amine concentration is essential. An over-concentration can lead to unnecessary regeneration of incompletely loaded amine, driving up energy costs. On the other hand, too low an amine concentration can result in the CO2 not being completely removed from the system. As a result, the CO2 cannot be completely stored and is released into the environment.
To tackle these challenges, the LiquiSonic® Measuring system is already widely used. It can continuously determine the concentration of the absorption liquid with an accuracy of up to ± 0.05%. By applying LiquiSonic® an efficient separation of CO2 is ensured, which simultaneously helps to minimize the costs for energy, chemicals, and laboratory work. The LiquiSonic® Measuring system therefore plays an essential role in ensuring and optimizing the efficiency and sustainability of the carbon capture process.
Contact process
Originally, the contact process (WSA) was developed to remove sulfur components from the exhaust gases of various industrial manufacturing processes. Unlike the double contact process, the water vapor remains in the resulting SO2. Thanks to a special vanadium-containing catalyst, the gas has no negative impact on the catalytic oxidation of SO2 to SO3 in the converter.
Finally, in the contact process, the sulfur trioxide enters the condenser, where water vapor condenses and SO3 into H2SO4 converts. A concentration of 98 wt% is typical here. To measure the concentration directly in the line, installation of the LiquiSonic®-sensors at the end of the condenser and the dilution unit is required.
Process optimization through combination measurements
In the consideration of multi-component systems, such as in the context of Benfield process gas scrubbers, the precise determination of the concentration of the washing solution and the salt content is an essential aspect for efficient and cost-optimized process management in the removal of CO2.
In this regard, the LiquiSonic® Measuring system provides a precise and continuous solution. It allows for accurate monitoring of the mentioned process parameters, enabling a significant reduction in material and energy costs while minimizing laboratory costs. Precise real-time monitoring also increases process safety, thereby reducing the risk of production downtimes.
In addition, the LiquiSonic® Measuring system scores with its robustness and durability. Even under demanding operating conditions, it reliably provides precise measurement values and is capable of capturing and documenting process fluctuations in real time.
