TDA Research, Inc. (TDA), in collaboration with the University of California – Irvine, the University of Alberta, and the Gas Technology Institute, will develop a new chemical absorbent-based air separation process that can deliver low-cost oxygen to integrated gasification combined cycle power plants. The specific objectives of the work are to increase the technical maturity and commercial viability of the new absorbent-based air separation technology by (1) demonstrating continuous oxygen generation in a prototype test system and (2) carrying out a high fidelity process design and economic analysis. The TDA prototype unit will consist of three fixed-bed reactors, which can generate a minimum of 1 kg/hour of oxygen on a continuous basis. The system will be capable of stand-alone operation, treating up to 12 normal cubic meter per hour air at different inlet pressures. In a series of tests, the research team will validate the results from the absorption model and computational fluid dynamics simulations and conduct multiple-cycle tests under optimum operating conditions, delivering a high purity oxygen product. This project leverages research from previous DOE contracts DE-FG02-05ER84216, DE-FG02-07ER84677, and DE-FE0024060.
