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. 

Stone Webster/Ionics A flue-gas desulfurization process in which the sulfur dioxide is absorbed in aqueous sodium hydroxide, forming sodium sulfite and bisulfite, the sulfur dioxide is liberated by the addition of sulfuric acid, and the reagents are regenerated electrolyti-cally. Designed by Stone Webster Engineering Corporation and Ionics Incorporated and operated in a demonstration plant in Milwaukee in 1974 but not yet commercialized. 

USC [Ultra Selective Conversion] A front-end process for improving the operation of catalytic crackers for making ethylene. Developed and offered by Stone Webster Engineering Corporation.

DCC is a FCC style process developed approximately 15 years ago by Sinopec RIPP [1,2]. Its objective is to convert the feedstock to propylene and gasoline. Shaw (Stone Webster at that time) licensed several RFCC units to Sinopec. This relationship led to an exclusive partnership for the DCC process and incorporated several of our FCC/RFCC mechanical design aspects.
