Variable Pressure Adsorption (VPA) CO2 removal process is widely used in ammonia, methanol, butanol decarbonisation units and urea, soda ash, industrial CO2 purification CO2 units as well as chi gas and CO2-containing tail gas recovery units due to its high degree of automation, convenient adjustment of removal accuracy, wide range of application, low energy consumption, and other features.

Nitrogen generator by pressure swing adsorption (PSA nitrogen generator for short) is a nitrogen generation equipment designed and manufactured according to the gas separation theory of pressure swing adsorption.

Wet decarbonisation is a widely used decarbonisation process with low energy consumption and is widely used to remove CO2 and H2S from ammonia, methanol feedstock gas, refinery gas, city gas and natural.

Ionic liquids are substances composed of anions and cations that are liquid at or near room temperature. Unlike typical organic solvents, there are no electrically neutral molecules in ionic liquids, it is all anions and cations.

Ionic liquid flue gas desulphurisation technology is mainly used for the treatment and resource utilisation of sulphur dioxide in flue gas and other industrial waste gases. This technology can recover sulphur dioxide with purity as high as 99.5% for the production of chemical products such as sulphuric acid, liquid SO2 or sulphur at the same time of efficient desulphurisation, thus realising the resourceful use of sulphur pollutants.
