Hainan Refining & Chemical’s crude oil adaptation project approved 2026-03-03 15:08:47 In February, the Hainan Provincial Department of Ecology and Environment issued a letter approving the environmental impact assessment report for China Petrochemical Hainan Refining & Chemical Co., Ltd.’s crude oil adaptation project. 　　Basic Information on the Project China Petrochemical Hainan Refining & Chemical Co., Ltd. (hereinafter referred to as Hainan Refining & Chemical) is located in the Yangpu Economic Development Zone of Hainan Province. The plant is divided into a refining area focused on atmospheric and vacuum distillation, and a chemical processing area centered on ethylene cracking. The Crude Oil Adaptation Project (hereinafter referred to as the “Project”) is located within the refining area of Hainan Refining & Chemical Co., Ltd. It aims to adjust the feedstock specifications by increasing the sulfur content of the crude oil from 1.0 wt% to 1.5 wt%, while keeping the crude oil processing capacity and process routes unchanged. Material upgrades and adaptation measures will be carried out on six units, including atmospheric and vacuum distillation, residue hydrogenation, Unit 1 hydrocracking, desulfurization and dewaxing, acidic water stripping, and solvent regeneration (mainly involving the addition or replacement of tower internals, heat exchangers, air coolers, heaters, pumps, and pipelines). A new non-hydrogenative acidic water stripping unit with a design capacity of 80 tons per hour will be added to the acidic water stripping unit, and a desulfurization solvent regeneration unit with a design capacity of 250 tons per hour will be added to the solvent regeneration unit. The associated utility systems, storage and transportation facilities, environmental protection systems, and auxiliary facilities will all make use of the existing infrastructure.
