Abstract

The invention relates to the technical field of pressure swing adsorption decarburization and discloses a novel saturation adsorption process of pressure swing adsorption decarburization and a device thereof. According to the process, CO2 gas in raw gas is adsorbed and removed by adsorbents in adsorption towers which are arranged in parallel, so as to obtain purified gas. Each circulation of the process comprises adsorption, uniform pressure drop, recycling, vacuumization, uniform pressure rise, isolation and final boosting, wherein the adsorption includes front adsorption, adsorption and back adsorption; the front adsorption specifically comprises the steps of inputting the output gas at the stage of the back adsorption of other adsorption towers and outputting the purified gas; the adsorption specifically comprises the steps of inputting the raw gas and outputting the purified gas; the back adsorption specifically comprises the step of outputting gas which exceeds the indexes of the purified gas, so as to be used as the input gas of the front adsorption or the final inflated gas of the final boosting; the final boosting comprises the step of boosting the adsorption tower by adopting the gas which exceeds the indexes of the purified gas and is output by the back adsorption of other adsorption towers. The novel saturation adsorption process has the advantages of high CO2 absorptivity, less loss of effective constituents in the gas and the like.

Description

technical field [0001] The invention relates to the technical field of pressure swing adsorption decarburization, and more specifically relates to a novel saturated adsorption process and device thereof for pressure swing adsorption decarburization. Background technique [0002] The working principle of pressure swing adsorption (PSA): using the selective adsorption of different adsorbents by the adsorbent and the difference in the capacity of the adsorbent to the adsorbate as the pressure changes, under the condition of selective adsorption of the adsorbent, high-pressure adsorption The specific components in the raw material gas are desorbed under low pressure to regenerate the adsorbent. At the same time, multiple sets of adsorption devices are designed to change the working pressure of each group in groups to achieve continuous separation of specific components in the raw material gas. The purpose of components, so as to achieve continuous production. [0003] Pressure ...
