Nitrogen Rejection using a Proven Adsorbent shows Ground Breaking Cost and Process Efficiency.

Presented at 2017 Spring Conference held at Hilton Garden Inn, Milan North on 17 - 19 May 2017 by Paul Bieniawski, Carlos Flores, & Jasper Klapwijk, Zechstein Midstream Partners, and Hiva Goudarzi, Engie E&P Deutschland GmbH
Zechstein Midstream has developed a pressure swing adsorption process which utilizes a chemical adsorbent that has been in wide use for the past twenty years for adsorption of hydrocarbons from water and air. The application of the adsorbent for nitrogen rejection is highly promising and the efficiency of the rejection process is in excess of 99% in a single pass. The solution is modular and can be fitted into standard intermodal shipping containers for simple installation, expansion and removal.
A pilot plant is currently in operation in the United States and studies indicate significant cost and environmental advantages over conventional cryogenic approaches. This enhancement of existing PSA technology offers the potential to structurally change the landscape for producing pipeline specification methane from high nitrogen sources.
