China cracking operations

DCC [Deep catalytic cracking] A general term for processes which convert heavy petroleum feedstocks and residues to hght hydrocarbons. One such process, for making C3-C5 olefins, was developed by the Research Institute of Petroleum Processing, China, and licensed through Stone Webster. Five units were operating in China in 1997. 

A significant application of FF on a commercial scale is the FF regenerator in fluid catalytic cracking processes. In Chapter 9, J. Chen, H. Cao, and T. Liu of Luoyang Petrochemical Engineering Corporation (LPEC) describe the development and design of four types of FF regenerators and the results of their commercial operation. More than 30 such units are in operation in China. 

The EUREKA process is a commercially proven thermal craeking process of semi-batch reactors system to produce valuable cracked oil and aromatic petroleum pitch from heavy residual material. The first unit was built in Sodegaura Refinery of Fuji Oil, Japan in 1975. The second unit was built in Nanjing, P. R. China in 1988. Both the units are now operated effectively for heavy oil upgrading.
