(354f) Process Design and Integration of Membrane-Cryogenic CO2 Capture Systems for Industrial CO2 Emissions

Global efforts to reduce CO₂ emissions are continuously being carried out, to deal with environmental protection and climate change. The implementation of the CO₂ capture technology has been regarded as one of the realistic ways for reducing CO₂ emissions emitted from industrial sites including power generation, cement, refinery and steel industries.

This study focuses on how to cost-effectively and energy-efficiently integrate membrane-cryogenic systems for CO₂ capture of industrial CO₂ emissions. Superstructure-based optimization framework is applied to determine optimal equipment configuration and operating condition for a variety of industrial CO₂ emitting sources. A case study illustrates how the process design and energy consumption of membrane-cryogenic CO₂ capture system is affected by the CO₂ concentration in the feed gas. Then, the economic feasibility of the membrane-cryogenic CO₂ capture process is assessed at the level of conceptual design.
