The Split Flow Process of CO2 Capture with Aqueous Ammonia Using the eNRTL Model

Carbon Capture and Storage (CCS) technology has attracted increasing attention as global climate change accelerates. dioxide removal processes under development include pressure swing adsorption (PSA) chemical absorption using amine solvents. In this paper, an ammonia solvent, which is relatively inexpensive good material properties, was used instead of amines in the carbon process simulation a method. This eNRTL thermodynamics model advantage predicting ions liquid phase Aspen Plus. A case study (Case Study 1) conducted to verify validity thermodynamic model. The purpose research find operating conditions eliminate more than 90% contained flue gas from coal-fired power stations, lower heat duty cost conditions. second 2) by comparing various Additionally, paper determined manipulating amount steam cooling water. results showed that heater’s outlet temperature should be set at 80 ℃ costs. As result changing flow rate side stream split process, energy consumption reduced when compared conventional process. It shown superior with 10.24% less use flow. study, achieved saving 95% achieved.
