Conventional decarbonization technologies are generally divided into dry decarbonization and wet decarbonization technologies, in which dry decarbonization generally adopts pressure swing adsorption technology; wet decarbonization generally adopts MDEA solution absorption regeneration technology. Pressure swing adsorption: Under a certain pressure, using an adsorption bed composed of activated carbon, silica gel, molecular sieve, and alumina adsorbents, methanol cracking gas, synthetic ammonia purge gas, catalytic cracking dry gas from an oil refinery, shift gas, CO2 components in various gas sources such as water gas and semi-water gas are selectively adsorbed under pressure, and the remaining components are output from the outlet of the adsorption tower as product gas to achieve the purpose of removing CO2. MDEA solution absorption and regeneration: Under low temperature and high pressure, MDEA solution can absorb carbon dioxide in raw gas very well. Under high temperature and low pressure, carbon dioxide is desorbed from the solution and enters the downstream carbon dioxide storage or reuse process.
