Abstract

In response to the characteristics of high synthesis gas temperature (,>, 200 ℃), high pressure (3.35 MPa), high saturated water content and complex components (including CH,4, H,2, CO,2, CO, etc.) prepared by underground coal gasification (UCG) technology, a membrane separation + solvent absorption coupling treatment method was designed to achieve CO,2, removal and H,2, purification from underground coal gasification syngas. The underground coal gasification syngas was treated by a secondary membrane separation unit to achieve the separation of CO,2,/H,2, and CH,4, and the decarbonized purified gas is obtained, where the CO,2, content (mole fraction) is less than 3%. The energy consumption required for this membrane separation process is 0.297 kW·h/m,3,. The CO,2,/H,2, mixture was treated by amine absorption method, and the research was conducted by the methods of formula solution screening, process optimization and check analysis. Finally, the product with H,2, purity (mole fraction) ≥ 99% is obtained. The energy consumption of the amine absorption method is 0.341 kW·h/m,3,. Using membrane separation + solvent absorption coupling treatment method to treat underground coal synthesis gas under complex working conditions, decarbonized purified gas, pure CO,2, and industrial grade H,2, can be obtained, greatly improving the economic value of the project and having great application potential.
