1Techno-economic comparison of three technologies for precombustion CO2 capture from a lignite-fired IGCC显示文摘This paper compares the techno-economic performances of three technologies for CO2 capture from a lignite-based IGCC power plant located in the Czech Republic:(1)Physical absorption with a Rectisol-based process;(2)Polymeric CO2-selective membrane-based capture;(3)Low-temperature capture.The evaluations show that the IGCC plant with CO2 capture leads to costs of electricity between 91 and 120€·MWh−1,depending on the capture technology employed,compared to 65€·MWh−1 for the power plant without capture.This results in CO2 avoidance costs ranging from 42 to 84€·tCO2,avoided−1,mainly linked to the losses in net power output.From both energy and cost points of view,the low-temperature and Rectisol based CO2 capture processes are the most efficient capture technologies.Furthermore,partial CO2 capture appears as a good mean to ensure early implementation due to the limited increase in CO2 avoidance cost when considering partial capture.To go beyond the two specific CO2-selective membranes considered,a cost/membrane property map for CO2-selective membranes was developed.This map emphasise the need to develop high performance membrane to compete with solvent technology.Finally,the cost of the whole CCS chain was estimated at 54€·tCO2,avoided−1 once pipeline transport and storage are taken into consideration.Simon Roussanaly Monika Vitvarova Rahul Anantharaman David Berstad Brede Hagen Jana Jakobsen Vaclav Novotny Geir Skaugen 2020Frontiers of Chemical Science and Engineering2020,14,3:3
