ROTTERDAM, Netherlands, November 2, 2021​ - LyondellBasell (NYSE: LYB), the world’s largest licensor of polyolefin technologies, today announced Lianyungang Petrochemical Co., Ltd (a company of Zhejiang Satellite) has again selected LyondellBasell’s Hostalen “Advanced Cascade Process” (Hostalen ACP) technology for a second 400 kiloton (kt) per year high density polyethylene (HDPE) plant. The new facility will be built at Lianyungang, Jiangsu Province, China.

“We are excited about this additional award from Lianyungang Petrochemical Co., Ltd which demonstrates the credibility LyondellBasell has in the polyethylene market,” said Jim Seward, Senior Vice President R&D, Technology and Sustainability at LyondellBasell. “Additionally, with this license, the global nameplate capacity of Hostalen ACP will exceed 10 million tons per year.”

The Hostalen ACP technology is the process of choice for the production of high-performance multimodal HDPE products.

“The selection of the Hostalen ACP technology was the best choice for us as we are very satisfied with the performance of our existing Hostalen ACP line,” said Mr. Lu Wei Wei, Vice President of Zhejiang Satellite. “The market appreciates the HDPE resins out of LyondellBasell’s low-pressure slurry process and the technology enables us to produce reliably and economically“.

The Hostalen ACP process technology manufactures high performance, multi-modal HDPE resins with an industry-leading stiffness/toughness balance, impact resistance, high stress cracking resistance and process advantages used in pressure pipe, film, blow molding and caps & closure applications.

The Hostalen ACP plant will commence operations using Avant Z501 and Avant Z509-1 catalysts to produce a full range of multi-modal HDPE products.
