Sinopec starts up Dupont STRATCO alkylation technology units

DuPont Clean Technologies (DuPont) has announced successful performance tests for the STRATCO® alkylation units at the Zhenhai Refining and Chemical Co. (ZRCC) refinery in Ningbo, Zhejiang, China and the Yangzi Co. (YPC) refinery in Nianjing, Jiangsu, China. These performance tests certify that the STRATCO alkylation units are meeting performance guarantees. The ZRCC and YPC STRATCO alkylation units both process MTBE raffinate feeds and are designed to produce 7700 bpd (300 000 tpy) and 7500 bpd (300 000 tpy) of alkylate, respectively.

The alkylation units will enable Sinopec to generate low-sulfur, high-octane, low-Rvp alkylate with zero olefins that meets the criteria of the China VI standard.

“The successful startups and operation at the Zhenhai and Yangzi refineries continue to demonstrate excellence in the application of the STRATCO alkylation technology in the Sinopec organisation. This endeavour of designing and building seven alkylation units over the last several years has created strong relationships with each of the refineries. We are grateful for this opportunity to provide Sinopec with our reliable technology that enables them to produce high quality alkylate, improving the quality of the refinery gasoline pool,” said Kevin Bockwinkel, global business manager, STRATCO Alkylation Technology.

The STRATCO alkylation technology is a sulfuric acid-catalysed process that converts low-value, straight-chain olefins (propylene, butylene and amylene) into high-value, branched components called alkylate. Alkylate is known for its superior blending properties and is a key component for clean gasoline. The technology helps refiners safely produce cleaner-burning gasoline with high octane, low Reid vapour pressure, low sulfur, zero aromatics and zero olefins. Licensed and marketed by DuPont as part of its Clean Technologies portfolio, the STRATCO alkylation technology is featured in more than 100 licensed units worldwide and more than 915 000 bpd (35 800 000 tpy) of installed capacity. DuPont is committed to alkylation research and has extensive experience in assisting refiners with alkylation research, design, start-ups, test runs, troubleshooting, optimisation, revamps, expansions, analytical testing, operator training, turnarounds and HAZOP studies.
