Sinopec Zhongyuan Oil Field Company Refinery CCS-EOR Project

Abstract

This paper describes the world's largest carbon capture and storage project applied to a fluid catalytic cracking (FCC) process at a Sinopec oil refinery in He’Nan Province, China. FCC units emit a large amount of CO2 in the process of regenerating catalysts deactivated by carbon deposits. There are few carbon capture pilots around the world targeting FCC regeneration flue gas. This project started construction in 2014 and was commissioned in June 2015. The pollutant removal process includes four major units: NOx removal; SOx and particulate removal; treatment of waste water associated with SOx removal; CO2 capture and liquefaction. Since becoming operational more than one year ago, the project has generated significant economic and environmental benefits by reducing SOx, NOx, particulate and CO2 emissions. The project provides valuable experience for whole chain CCS operation in China.
