燃煤电厂CO2捕集与咸水层封存全过程经济性模型
A model of economy for overall process of CO2 capture and saline storage
摘要
Abstract
Carbon capture and storage (CCS) consists of separation, compression, transportation and storage of CO2 from exhaust gas such as vent gases of coalfired power plant. CCS is considered to be the most effective choice for mitigating greenhouse gas of CO2 in the middle and short-term, and attracts more attention recently. Although CCS has been proved to be feasible in technology, it is still unsuitable for commercialization on a large scale due to high cost at present. Most models developed for cost estimation focused on individual process of CCS, especially on capture process. In this paper, definition formulas were given to calculate the total cost of CCS overall process and of emission cuts of CO2. Furthermore, a model economy is developed to estimate total capital and cost for MEA capture, compression, pipeline transportation and saline storage. The economic study for a case of 600 MW PC power plant is also carried out in the paper. The results show that, when CO2 recovery efficiency ranges from 70% to 99% , the total CCS cost for the case is 257-269 CNY · (t CO2)-1 , and the cost for emission reduction of CO2 is 364. 8- 384. 2 CNY · (t CO2)-1 respectively.关键词
