MTR Carbon Capture products

MTR's PolarCap™ process leverages the innovative Polaris™ polymeric membrane, the first commercial membrane developed specifically for CO2 capture. The PolarCap™ process uses passive separation of CO2 driven by blowers and pumps, avoiding chemical reactions typically required in amine-based capture. This makes PolarCap™ an environmentally friendly option that solely relies on electricity, making it ideal for retrofit applications in coal-fired power plants. The compact, modular design of membrane skids allows these capture systems to be integrated into existing plants with limited space. MTR provides two capture rate designs for coal-fired plants: a high CO2 removal rate at 90% and a partial capture rate around 60%. This flexibility enables cost-effective solutions based on specific requirements, emphasizing ease of integration and operational efficiency.

Membrane Technology and Research, Inc. (MTR) offers an advanced CO2 capture solution specifically designed for natural gas combined cycle (NGCC) power plants. This system utilizes a selective exhaust gas recycle (S-EGR) configuration that leverages incoming combustion air as a sweep to pre-concentrate CO2 from 4% to around 20%. This pre-concentration is achieved with minimal energy input, offering a more efficient process compared to simple exhaust gas recycling. The selective membrane design can decrease the energy requirements of the CO2 capture step by up to 40%, significantly reducing operational costs. An all-membrane approach, using a capture step in series with selective recycle membranes, is capable of capturing up to 80% of CO2 emissions from NGCC plants. This method not only requires less energy but is also more cost-effective compared to traditional amine-based processes. These systems are vital in providing the flexibility needed to track the variable load conditions that are typical in modern NGCC power plants, which often need to balance both steady baseload power and the intermittent nature of renewable energy sources like wind and solar.
