Membrane Technology and Research Inc. (MTR), partnered with Sargent & Lundy (S&L) and CEMEX, is performing an initial engineering design of a full-scale Polaris membrane carbon dioxide (CO2) capture system (approximately 1 million metric tonnes of CO2 per day) applied to the CEMEX Balcones cement plant located in New Braunfels, Texas. This study will produce estimates of the cost and performance of a first-of-its-kind industrial membrane capture plant at a cement plant. The technical activities include completing a project design basis and process design; estimating the cost of the capture plant construction and installation; performing an environmental health and safety (EH&S) review, permitting and constructability reviews, and a hazard and operability study (HAZOP); and preparing a techno-economic analysis (TEA).
