Successful startup of world's largest catalytic dehydrogenation for Hengli
The world's largest catalytic dehydrogenation plant, located at Hengli Petrochemical (Dalian) Refinery Co., Ltd.'s site in Liaoning Province, China, has been successfully tarted up. This single-train dehydrogenation unit uses McDermott's Lummus process technology together with Clariant's CATOFIN™ catalyst and patented metal-oxide Heat Generating Material (HGM).
The plant processes a mixed feed of 500 KTA of propane and 800 KTA of isobutene for the production of propylene and isobutylene. In addition to the technology license, McDermott also provided the process design package, training, and technical support for this plant.
"Lummus CATOFIN technology continues to be the dehydrogenation technology of choice, continually exceeding customer expectations for overall performance," said Leon de Bruyn, Senior Vice President of McDermott's Lummus Technology business. "This technology offers lower capital and operational costs for our customers, combined with unmatched reliability and optimization."
Founded in 1994, Hengli Group is one of China’s foremost suppliers of petrochemicals. Guangqin Peng, Chief Engineer of Hengli Petrochemical (Dalian) Refinery Co Ltd, stated, “We are very proud of our achievements on this groundbreaking project. The fast, smooth and successful startup of this world’s largest paraffin dehydrogenation unit would not have been possible without reliable and experienced partners like Clariant.”
CATOFIN is an extremely reliable technology for light paraffin dehydrogenation. Operating at thermodynamically-advantaged reactor pressure and temperature to maximize yield, the process relies on Clariant’s highly selective CATOFIN catalyst and the company’s patented metal-oxide HGM to deliver high conversion rates. With the successful startup of the Hengli plant, this now marks Clariant’s 21st CATOFIN unit in operation, totaling over 9 million tons of olefin production capacity globally.
McDermott's Lummus Technology is a leading licensor of proprietary petrochemicals, refining, gasification and gas processing technologies, and a supplier of proprietary catalysts and related engineering. With a heritage spanning more than 100 years, encompassing approximately 3,100 patents and patent applications, Lummus Technology provides one of the industry's most diversified technology portfolios to the hydrocarbon processing sector.
