Wanhua Chemical (Penglai) Co., Ltd. Dimethyl Carbonate-to-Propylene Glycol Conversion ProjectProject Name: Wanhua Chemical (Penglai) Co., Ltd. Dimethyl Carbonate-to-Propylene Glycol Conversion Project
Initial Release Date: April 15, 2026
Location: Shandong Province
Industry/Project Type: Chemicals and Pharmaceuticals/Chemical Raw Materials and Products/Chemical Raw Materials
Project Owner: Wanhua Chemical (Penglai) Co., Ltd.
Total Investment: 268.42 million RMB
Current Status: Project registration
Construction Site: Penglai Chemical Industry Park, Yantai City, Shandong Province
Construction Details: The project involves converting the existing dimethyl carbonate production unit from the original carbonate project into a facility for producing propylene glycol (PG). Propylene oxide (PO) and an aqueous propylene glycol solution will be used as raw materials. The planned annual production capacity of propylene glycol is 80,000 tons. Additionally, the project is expected to produce 7,700 tons per year of dipropylene glycol (DPG) and 770 tons per year of tripropylene glycol (TPG) as by-products. This project is a conversion from the dimethyl carbonate (DMC) unit of the original carbonate project. Equipment for high-pressure reactions, such as reactors, has been newly added; most of the other equipment is reused from the original DMC unit, while a small amount of equipment is repurposed from the propylene carbonate (PC)/ethyl methyl carbonate (EMC) unit. Milestone: April 14, 2026 – The project registration has been approved.
