A critical analysis of CO2 capture technologies

摘要

The use of fossil fuels as a source of energy continues to add carbon dioxide(CO2) to the atmosphere,causing detrimental effects to the environment.Scientists around the world are working to reduce the effects of CO2 emissions,and many research efforts are ongoing at both academic and industrial levels.Among the available CO2 capture technologies,solvent-based technologies are commercially proven and practiced in many industries.Despite the commercialization of solvent-based technologies,research on CO2 capture processes is still vigorously being pursued to significantly minimize capital and operating costs per ton of CO2 capture,while improving operational reliability In the last decade,solid sorbents have been recognized as a very promising technology for CO2 capture,with the potential to overcome the existing limitations of solvent-based technologies.This article highlights the recent developments in commercial solvent-based technologies and compares their economics with a proprietary hydrated sorbent process for CO2 capture recently developed by the authors'company.
