Cost structure and performance of CO_2 capture unit using split-stream cycle

摘要

This work evaluated an overall performance, energy consumption and cost of the CO_2 capture unit using split-flow configuration. The evaluation was carried out using our mechanistic mass-transfer, hydrodynamic and economic model. The model accounted for mechanism of liquid flow distribution, mass-transfer process with chemical reactions, and vapor-liquid equilibrium. The overall process performance was presented in terms of reboiler heat-duty for solvent regeneration, size of regenerator, and size of absorber.
