Title: A Contaminant Tolerant Solvent Stripping Chemical Hybrid Process for Carbon Capture in Existing Coal-Fired Power Plants

Abstract

In the context of post combustion CO 2 capture process, solvents with fast CO 2 absorption rates will require more energy for regeneration. This challenge is exacerbated when aqueous solvents are applied to post-combustion CO 2 capture from utility gas stream with unique characteristics such as high volumetric flow rate, low CO 2 vapor pressure and the presence of gas contaminants. This Small Business Innovation Research project is developing a novel contaminant-tolerant solvent/stripping chemical hybrid process for post-combustion CO 2 capture from utility flue gas. The process will use a proprietary solvent technology to achieve DOE’s goal of 90% or greater CO 2 emissions reduction at existing coal-fired power plants with no more than a 35% increase in cost of energy services. In Phase I, the proposed solvent was investigated and compared with 30% wt MEA benchmark, through laboratory testing and system simulation, in the areas of reaction kinetic, mass transfer, stability, and energy consumption. The technical feasibility of the technology is proven in phase I by demonstrating advantageous results over benchmark. In phase II, the solvent technology and process will be evaluated in many aspects in a pilot test facility and further validated at the National Carbon Capture Centermore » (NCCC) in preparation for commercialization in Phase III. A detailed techno-economic analysis will be performed to demonstrate that the proposed solvent and process could potentially meet the DOE target for CO 2 capture. The proposed solvent technology, when developed, will improve the economics of the national greenhouse gas sequestration program, improve the overall plant efficiency of existing coal-fired power plants and reduce cost burden to utility industry and public as a whole.« less
