Benchmarking of a novel solid sorbent CO2 capture process for NGCC power generation

摘要

The successful deployment of any technology depends on many important factors. One of the critical ones that affect the success of post combustion CO2 capture technologies is the ability to reduce the increase in cost of electricity associated with retrofitting the capture unit to electricity generating power plants. High capture costs associated with conventional MEA solvent processes has opened an opportunity for the emergence of many competing technologies aimed at reducing the cost of capture. This paper presents the technical and economic benchmarking of a polyethyleneimine (PEI)-based solid sorbent CO2 capture process as compared to the conventional MEA solvent process, with both technologies applied to a natural gas combined cycle (NGCC) power plant.
