摘要：
A pressure-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 product stream. The present process is particularly effective and beneficial in removing contaminants such as COand/or HS from a natural gas at high adsorption pressures (e.g., at least 3.45 MPaG (500 psig)) to create product streams of very high purity (i.e., very low contaminant levels).
