Zorb TM Sulfur Removal Technology To Be Installed At China’s Yanshan Refinery
Posted: 30 May 2005
ConocoPhillips’ proprietary S Zorb TM Sulfur Removal Technology (SRT) will be installed at Sinopec Beijing Yanshan Company’s Yanshan Refinery, Yanshan, Beijing , China . Sinopec Beijing Yanshan Company is a wholly owned subsidiary of Sinopec Corporation.
The 3,430 metric tons per day (approximately 30,000 barrels per day) S Zorb gasoline desulfurization unit, being designed to process full-range naphtha from the Fluid Catalytic Cracking (FCC) unit, is scheduled for startup in 2006. ConocoPhillips is working closely with Sinopec Beijing Yanshan Company to achieve an aggressive implementation schedule to ensure the unit is brought on-stream as soon as possible to meet the Beijing market’s high demand for ultra-low sulfur gasoline.
An advanced process technology that removes sulfur from gasoline streams through the use of a novel, regenerable sorbent, S Zorb SRT was developed to help refineries comply with increasingly stringent mandates for cleaner-burning fuels. The addition of the new S Zorb unit will enable the Yanshan refinery to cost-effectively achieve this compliance, as well as future low-sulfur requirements, while at the same time, minimizing refinery octane pool losses and hydrogen consumption normally associated with FCC gasoline desulfurization.
“In order to meet the daily increasing gasoline quality requirements in the Beijing market, S Zorb SRT is an optimal technology for both deep desulfurization and octane retention. We have chosen to adopt S Zorb technology to process FCC gasoline,” said Pr ofessor Yang Qingyu, vice president, Sinopec Beijing Yanshan Company.
“ConocoPhillips is pleased to be a contributor to the production of ultra-clean gasoline in the Beijing market,” said Brian Evans, manager, ConocoPhillips Technology Solutions Division. “This fast-track project is being developed to help reduce vehicle-generated emissions well in advance of the 2008 Olympic Games, which will be hosted in Beijing .”
Sinopec Beijing Yanshan Company’s Yanshan Refinery is one of China ’s largest refiners of fuel, lubrication oil and raw chemical materials, with a crude oil processing capacity of 9.5 million metric tons annually. It is the first refinery outside the U.S. to commit to build an S Zorb SRT unit. ConocoPhillips recently announced that a new S Zorb SRT unit will be built at Pasadena Refining System, Inc.’s Pasadena , Texas , USA , refinery, which represents the second S Zorb SRT unit to be built outside of ConocoPhillips’ own refining system.
Other S Zorb units are located at ConocoPhillips U.S. refineries in Borger , Texas , and Ferndale , Wash. , which have been successfully operating since 2001 and 2003 respectively. The company has a third S Zorb unit under construction at its Lake Charles refinery in Westlake , Louisiana , USA , with start-up scheduled for later this year.
