Project Description

Membrane Technology and Research (MTR) and partners will validate at pilot scale a cost-effective membrane process to separate CO2 from coal-fired power plant flue gas. The MTR innovative membrane design utilizes two key innovations: high CO2 permeance membranes and a countercurrent sweep module design. This project will advance MTR's membrane technology to the 1 MWe level. MTR will continue to operate an existing 0.05 MWe slipstream field test system, located at the National Carbon Capture Center (NCCC), to optimize membrane materials and module designs. A 1 MWe membrane skid capable of 90% CO2 capture from a 20 ton CO2 per day slipstream of coal-fired flue gas will be designed, constructed, and installed at the NCCC for a six-month field test. MTR's air sweep process design will be evaluated in collaboration with Babcock & Wilcox to determine the performance impact of retrofitting existing boilers. The Electric Power Research Institute will evaluate the benefits of flue gas water recovery, measure the quality of the water produced, and define water management for the integrated CO2 capture process. Results from the 1 MWe skid test program will be used to update a comparative economic analysis of the MTR membrane process to clarify the potential of the MTR membrane process and identify key cost-reduction milestones and success criteria necessary to meet the Department of Energy program goals.

Successor Project: DE-FE0013118

Project Benefits

This project focuses on the scale up of a high-permeance polymer-based membrane and process design. The process includes an air sweep step that transfers recycled CO2 to the boiler, increasing the driving force in the initial cross-flow membrane stage, reducing the required membrane area, total capital cost, and the overall energy cost. Specifically, this project will design, construct, and test a 1 MWe capacity membrane skid at the NCCC.
