Compound amine solution technology is applicable in acid gas removal of natural gas, shift gas, refinery gas, urban coal gas, coke oven gas, etc.
The technology adopts compound amine solution by adding activator in MEDA solution, it has both physical and chemical adsorptivity, the physical property of which can achieve desorption and regeneration under atmospheric pressure, and the chemical property of which can get thermal regeneration of a small amount of solution, and ensure the purity of gas. Therefore the technology has low heat consumption and high purification performance; it can remove the inorganic sulfur of sulfur-bearing gas, and meanwhile hydrolyze the organic sulfur.
Organic amine desulfurization process
The desulfurization process of organic amine is composed of a pre separator, an absorption device, a desorption device and an amine purification device.
