Cost Analysis and Process Design for CO₂ Capture Process with Gas Separation Membranes

Abstract

Membrane separation is a promising method for CO₂ separation from flue gases with low cost and energy consumption. This process comprises membrane modules, blowers, compressors, and heat exchangers. Cost estimation of the equipment is required to compare the performance of the process with other separation processes, such as the chemical absorption process or adsorption process. This paper explains process design and cost estimation methods for CO₂ separation by considering fixed and direct costs.
