Patent number: 8623926Abstract: Disclosed herein is a methanol production process that includes at least two membrane separation steps. Using the process of the invention, the efficiency of methanol production from syngas is increased by reducing the compression requirements of the process and/or improving the methanol product yield. As an additional advantage, the first membrane separation step generates a hydrogen-rich stream which can be sent for other uses. An additional benefit is that the process of the invention may debottleneck existing methanol plants if more syngas or carbon dioxide is available, allowing for feed of imported carbon dioxide into the synthesis loop. This is a way of sequestering carbon dioxide.Type: GrantFiled: April 13, 2012Date of Patent: January 7, 2014Assignee: Membrane Technology and Research, Inc.Inventors: Nicholas P Wynn, Sylvie Thomas-Droz, Meijuan Zhou, Zhenjie He, Haiqing Lin

Patent number: 6896717Abstract: A membrane-based process for separating mixtures of target gases if the gas mixture also contains C3+ hydrocarbon vapors. The process uses gas-separation membranes having a base membrane and a coating layer. The base membrane incorporates a selective layer made from a polymer selective between the light gases to be separated. The coating layer comprises a fluorinated polymer capable of protecting the base membrane from C3+ hydrocarbon vapors and liquids.Type: GrantFiled: July 2, 2003Date of Patent: May 24, 2005Assignee: Membrane Technology and Research, Inc.Inventors: Ingo Pinnau, Zhenjie He, Rolande J.
