Low-Pressure Membrane Contactors for CO2 Capture
Project No.: DE-FE0007553

Membrane Technology and Research, Inc. (MTR) is developing a new type of membrane contactor (or mega-module) to separate carbon dioxide (CO2) from power plant flue gas. This module’s membrane area is 500 square meters, 20 to 25 times larger than that of current modules used for CO2 capture. A 500-MWe coal power plant requires 0.5 to 1 million square meters of membrane to achieve 90 percent CO2 capture. The new mega-modules can drastically reduce the cost, complexity, and footprint of commercial-scale membrane module integration.  Energy savings due to low-pressure drops for gases circulated through the modules, as well as improved countercurrent flow, are additional benefits. The feasibility of using mega-modules in several different hybrid process designs is being evaluated for future development potential.
