Abstract

The invention provides a micro-channel absorber, wherein a main body part is a plurality of micro-channels which are along the flow direction of gas and liquid, have certain mutual spacing distance and are applicable to receiving gas and liquid fluids; a contact mode of material flow between gas which needs to be absorbed and an absorption liquid is cocurrent; and an inlet of the absorber is provided with corresponding distribution devices of the gas and the liquid, which ensures the even distribution of the gas and the liquid. The micro-channel absorber has large gas treatment capacity in unit volume, and has a compact structure; and the micro-channel absorber is particularly suitable for removing acid gas (such as CO2, H2S and the like) in mixed gas flow such as synthetic gas, natural gas, coking gas, tail gas of coal gas, oilfield associated gas and Claus tail gas to reach the requirements of environmental emission and subsequent process gas processing.

Description

technical field [0001] The present invention relates to a kind of microchannel absorber, can be particularly suitable for removing acid gas (such as CO 2 , H 2 S, etc.) to meet the requirements required for environmental emissions and subsequent process gas processing. Background technique [0002] H 2 There are many methods of S, which can be generally divided into dry desulfurization, wet desulfurization, membrane desulfurization, biological desulfurization and some latest desulfurization technologies. Among them, dry and wet desulfurization are more mature. Dry desulfurization uses various adsorbents (such as activated carbon, molecular sieve, MnO, ZnO, Fe 2 o 3 etc.) to adsorb H 2 S, but dry adsorption is suitable for low concentrations of H 2 S mixed air flow, where high purification treatment requirements are required, the adsorbent has low adsorption capacity and low selectivity, and is not suitable for processing high-concentration air flow, and it occupies a ...
