Working Principle

Feed gas enters the absorber, where acidic gases are absorbed through counter-current contact with amine solution. The rich amine solution is sent to the regenerator for heating and desorption to release acid gas. The regenerated lean amine solution is recycled, and the separated acid gas is sent to a flare or sulphur recovery unit.

Core Advantages

✅ Mixed MDEA amine solution with high absorption selectivity and low energy consumption 

✅ Optimized internals of towers for low solvent loss 

✅ Fully skid-mounted design, pre-assembled at factory; ready for commissioning after on-site connection 

✅ Equipped with rich/lean amine heat exchanger, cooler and flash drum 

✅ Online monitoring of H₂S and CO₂ content available

Technical Parameters

Outlet Specifications: H₂S ≤ 20 ppm, CO₂ ≤ 50 ppm Operating Pressure: 3.0~8.0 MPa Control Mode: Automatic regulation of amine circulation rate via DCS

Applications

Pre-treatment for LNG liquefaction, natural gas desulphurization and decarbonization, coalbed methane purification
