Hengli Petrochem starts up world largest catalytic dehydrogenation unit in China

July 19/2019

MOSCOW (MRC) -- McDermott announced the recent "successful" start-up of the "world's largest" catalytic dehydrogenation unit at Hengli Petrochemical (Dalian) Refinery Co.'s site in Liaoning Province, China, as per Apic-online.

The single-train dehydrogenation plant, which utilizes McDermott's Lummus Catofin technology and Clariant's Catofin catalyst, has the capability to process 500,000 t/y of propane and 800,000 t/y of isobutene for the production of propylene and isobutylene.

McDermott also supplied the process design package, training and technical support for the facility.

PCN earlier reported that the project was part of a new 20-million-t/y integrated refining and petrochemical complex at Hengli's site that includes a 450,000-t/y polypropylene plant and a 4.5-million-t/y aromatics facility. Completion is expected this year.

"Lummus Catofin technology continues to be the dehydrogenation technology of choice, continually exceeding customer expectations for overall performance," noted Leon de Bruyn, senior vice president of McDermott's Lummus Technology business.

As MRC informed before, in May 2018, INVISTAs technology and licensing group, INVISTA Performance Technologies (IPT), and Hengli Petrochemical (Dalian) Co.,Ltd. (Hengli) reached an agreement to license INVISTAs latest purified terephthalic acid (PTA) process technology for Henglis fourth PTA line. Henglis first three PTA lines, the first of which began operation in 2012, also utilize INVISTAs technology and have a combined capacity of 6.6 million metric tonnes per year. The fourth line will have a design capacity of 2.5 million metric tonnes per year and will be installed at Changxing Island, Liaoning Province of China.
