The invention relates to a set for separating two or more gases from each other, including: a first adsorption column set comprising at least two columns in series; an optional number of additional column sets comprising additional columns; connectors connecting each parallel additional column to the column; auxiliary equipment feeding a gas mixture to the columns and additional columns jointly and discharging separated gases according to pressure swing adsorption.

The invention provides a process for providing a hydrogen stream to a process utilizing hydrogen comprising obtaining a gas stream containing hydrogen and compressing the gas stream to a pressure of at least 600 psig, Then the compressed gas stream is sent to a pressure swing adsorption unit containing a plurality of beds with at least 5 pressure equalization steps to produce a hydrogen stream. The hydrogen stream can then be compressed and sent to a process utilizing hydrogen. The compressed gas stream may be chilled before entering the pressure swing adsorption unit.

Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve performing a startup mode process prior to beginning a normal operation mode process to remove contaminants from a gaseous feed stream. The startup mode process may be utilized for swing adsorption processes, such as TSA and/or PSA, which are utilized to remove one or more contaminants from a gaseous feed stream.
