Second public announcement for the environmental impact assessment of the 1 million-ton ethylene project 2025-07-21 16:19:29 On July 16, the second public announcement regarding public participation in the environmental impact assessment of Fuhai Tangshan Petrochemical’s methanol-naphtha-based olefin production project was made. Project Name: Fuhai Tangshan Petrochemical Methanol-Naphtha Coupled Olefin Production Project
Location: Caofeidian District, Tangshan City
Nature of Construction: New construction
Scope of Construction: Construction of a 1 million tons per year methanol-naphtha coupled cracking unit, along with a total of 17 downstream chemical processing units, as well as the corresponding utility systems and auxiliary facilities within the project boundary. The 17 newly built units are as follows: methanol-naphtha coupled cracking unit, butadiene unit, MTBE/butylene-1 unit (including selective hydrogenation and full hydrogenation units), cracked gasoline hydrogenation unit, aromatic extraction unit, VCM unit, PVC unit, EVOH unit, EVA/LDPE unit, FDPE unit, α-olefin unit, POE unit, PP unit, CHPPO unit, polyether polyol unit, 1,3-propanediol unit, and PTT unit. This project adopts a technology route of methanol-naphtha coupled cracking + light hydrocarbon cracking, and constructs a 1 million tons per year methanol-naphtha coupled cracking unit. The methanol-naphtha coupled cracking section processes methanol and naphtha, producing 350,000 tons of ethylene per year; the light hydrocarbon cracking section processes the ethane, propane, butane produced by the coupled cracking unit as well as some externally sourced butane, resulting in 650,000 tons of ethylene per year.
