The process of the present invention provides high recovery and low capital cost giving it an economic advantage over previously known purification processes. The present process has particular applicability to the purification of synthesis gases comprising at least hydrogen (H), carbon monoxide (CO), methane (CH), CO, and HO to obtain a gas stream including at least H, CO, and CH, that is substantially free of HO and CO. The process also has applicability to the purification of natural gases inclusive of at least CH, N, CO, and HO to produce a gas stream including at least CHand N, but which is substantially free of HO and CO.

High recovery process for purification of multicomponent gases

The present invention provides for a pressure swing adsorption (PSA) process for the substantial removal of HO and COfrom a synthesis gas to obtain a multicomponent product gas substantially free of HO and COwith high recovery of the product gas. Further, the present invention provides an integrated process that achieves sufficiently high Hand CO recoveries such that compression and recycling of the syngas purification PSA tailgas is not necessary to be economically advantageous compared to the conventional processes.

Process for purifying a synthesis gas

The present invention relates to a method for conditioning a soot-containing syngas stream in a single integrated apparatus containing a scrubbing vessel wherein particulate matter is decoupled from the waste water stream.
