TEMPERATURE SWING ADSORPTION PROCESS FOR THE SEPARATION OF TARGET SPECIES FROM A GAS MIXTURE

摘要

A temperature swing adsorption process for the removal of a target species, such as an acid gas, from a gas mixture, such as a natural gas stream. Herein, a novel multi-step temperature swing/pressure swing adsorption is utilized to operate while maintaining very high purity levels of contaminant removal from a produc t stream. The present process is particularly effective and beneficial in removing contaminants such as C02 and/or H2 S from a natural gas at relatively high adsorption pressures (e.g., at least 500 psig) to create product streams of very high purity (i.e., very low contaminant levels).
