燃煤电厂新增碳捕集和储存装置布置方案研究OA

At present,there is a lack of research on the layout of the newly added carbon capture and storage devices in the existing power plants in China,which is likely to cause a large amount of new land occupation,difficult pipeline layout,and affect the selection of related equipment,resulting in an increase in investment.Based on the existing plant conditions and characteristics of a 2×350 MW power plant with indirect dry cooling tower of three incorporate towers system,two layout schemes for adding a 200,000-ton/year carbon capture and storage device were proposed and compared technically and economically.It is recommended to make full use of the space in the indirect dry cooling tower to arrange carbon capture and storage devices.The scheme has advantages in technological process,environmental protection,land occupation,cost,etc.However,attention should be paid to the reasonable arrangement of the construction and installation plan in the indirect dry cooling tower and the calculation of the impact of the newly added carbon capture facilities in the indirect dry cooling tower on the performance of the existing indirect dry cooling tower.
