The Amine Solvent Technology is employed in the field of CO2 capture to remove carbon dioxide from industrial processes or exhaust gases. In this technology, a solvent based on amines, often Monoethanolamine (MEA) or other amines, is used to selectively absorb CO2 from gas streams. The process takes place in an absorption unit where the gas flows through the amine solvent. The amine molecules react with the CO2, forming stable compounds. Subsequently, the loaded solvent is directed to a desorption unit where the CO2 is released again by increasing the temperature or reducing the pressure. This cycle allows for continuous separation of CO2 from gas streams. The Amine Solvent Technology plays a crucial role in reducing greenhouse gas emissions in industrial processes and improving environmental sustainability.

Pressure Swing Adsorption (PSA) - Technology

The Pressure Swing Adsorption (PSA) technology is employed in the field of CO2 capture to efficiently and selectively remove carbon dioxide from gas mixtures. In this process, the gas mixture is passed through an adsorption unit under elevated pressure, which is filled with a specialized adsorbent. The adsorbent selectively binds CO2, temporarily retaining other gas components. After a specific period, the pressure in the system is reduced, relieving the adsorbent and releasing the captured CO2. This cyclic shift between pressure increase and reduction enables continuous CO2 separation. PSA technology is characterized by its flexibility and adaptability, making it attractive for various applications, including the reduction of CO2 emissions in industrial processes. Continuous advancements in this technology aim to enhance its efficiency, positioning it as a significant component in the pursuit of more sustainable environmental impacts.

This advanced technology utilizes temperature fluctuations to efficiently separate carbon dioxide from gas mixtures. In a TSA system, the gas mixture passes through an adsorber filled with a suitable adsorbent. The adsorbent captures CO2 at low temperatures. Subsequently, the temperature is increased, releasing and regenerating the adsorbent. The cyclic transition between adsorption and regeneration allows for continuous CO2 separation. TSA technology offers the advantage of thermal regeneration, making it particularly effective and energy-efficient. This advanced method plays a crucial role in efforts to reduce CO2 emissions and has the potential to make a sustainable contribution to combating climate change.
