Using its own technology, Hualu Hengsheng’s 200,000 tons per year dicarboxylic acid project

Thread Content

On September 8, Hualu Hengsheng (600426.SH) announced that its 200,000-ton/year dicarboxylic acid production project has completed all processes, produced qualified products, and entered the trial production phase. The total estimated investment for the project is 867 million yuan. It will utilize proprietary technology to build a 200,000-ton/year dicarboxylic acid production facility, along with corresponding tank areas, utility systems, auxiliary facilities, as well as safety and environmental protection measures. Project name: 200,000 tons/year dicarboxylic acid project. Construction unit: Shandong Hualu Hengsheng Chemical Co., Ltd. Construction location: It is situated in the Dezhou Canal Hengsheng Chemical Industry Park. The diacid production facility is located on the newly acquired land to the west of Hualu Hengsheng Plant C, while the cellosolve capacity expansion facility is located within Plant C of Hualu Hengsheng. Project investment: The total investment amounts to 866.68 million yuan, of which 7.9 million yuan is allocated to environmental protection measures, accounting for 0.09% of the total investment. Land area: The total land area required for the proposed project is 59,467 square meters, approximately 82 mu. Among them, the dibasic acid plant area covers 25,952 square meters; it is new land acquired, and its current use is industrial ； All other facilities are located within Hualu Hengsheng’s existing plant area, with no new land acquisition required. Construction details: Using carbon monoxide, oxygen, methanol, and nitric acid as raw materials, and employing advanced CO coupling technology for the production of dimethyl oxalate, the dimethyl oxalate production unit in the existing \"500,000 tons per year ethylene glycol plant\" will be upgraded. This upgrade will result in an additional annual production capacity of 190,000 tons of dimethyl oxalate, along with 4,194 tons of dimethyl carbonate as a by-product each year. “The \"200,000-ton per year dicarboxylic acid project\" uses dimethyl oxalate (provided through the expansion and upgrading of the oxalic acid production facility) and deionized water as raw materials. It employs advanced technology for the hydrolysis of dimethyl oxalate to produce dicarboxylic acid, and aims to build a plant with an annual production capacity of 200,000 tons. Corresponding facilities such as tank areas, utility systems, auxiliary equipment, as well as safety and environmental protection systems are also included in this project ； Once the facility is completed and put into operation, it will produce 200,000 tons of dicarboxylic acid products per year.
