A PLANT AND PROCESS FOR SIMUTANEOUS RECOVERING MULTIPLE GAS PRODUCTS FROM INDUSTRY OFFGAS Abstract 5 The present invention relates to a process and plant for the simultaneous recovery of high purity carbon dioxide, high purity hydrogen and high calorific fuel gas, from a low pressure gas stream such as the tail gas from a hydrogen stream reforming pressure swing adsorption(PSA) 10 unit of a refinery plant or similar. The invention utilizes at least one of the following adsorbent materials, which may include but not limited to, zeolite x, zeolite A, silica gel, activated carbon, activated alumina and other highly porous materials. The invention 15 may include two or more than two stages of adsorption separation processes. The invention produces high purity hydrogen, and high heat value fuel gas, as a result of separation. CC.)
