Recently, the Department of Ecology and Environment of Xinjiang Uygur Autonomous Region officially accepted the environmental impact assessment documents of Xinjiang Zhongtai Jinhui Technology Co., Ltd. with an annual output of 300,000 tons of BDO.
Xinjiang Zhongtai Jinhui Technology Co., Ltd. BDO project with an annual output of 300,000 tons
Construction nature: new construction
Construction site: New District of Baicheng Industrial Park
Project investment: The total investment is 5,115.66 million yuan, including 1,534.70 million yuan of self-owned funds and 3,580.96 million yuan of debt financing
Construction period: The construction period of the entire project is 27 months
The production area of the project mainly includes main works, auxiliary works, public works and environmental protection works. The main project includes a 28,000Nm3/h natural gas hydrogen production unit, a 120,000 t/a calcium carbide acetylene unit, a 3×240,000 t/a formaldehyde unit, a 3×100,000 t/aBDO unit, and a 20,000 t/a waste sulfuric acid unit. recycling device.
Main engineering process plan
The project adopts the acetylenic aldehyde process route to produce BDO, and the main raw materials are hydrogen, acetylene and formaldehyde. Among them, the hydrogen source hydrogen production device uses the natural gas provided by the park as the raw material, and produces hydrogen through transformation and pressure swing adsorption. Formaldehyde plant uses purchased methanol as raw material to produce formaldehyde by iron-molybdenum method. Acetylene plant uses calcium carbide produced in the park as raw material to produce acetylene.
The BDO device uses acetylene and formaldehyde as raw materials, and uses the acetylene aldehyde method to catalyze the reaction to generate 1,4-butynediol (BYD), which is then reduced by hydrogen to produce 1,4-butanediol (BDO).
BDO has several production process routes, among which the main raw materials for the acetylene aldehyde production process are acetylene and formaldehyde. After Jinhui Zhaofeng cooperated with Zhongtai Group, it has a strong group balance advantage in the supply of calcium carbide acetylene, both belonging to Zhongtai Group. Xinjiang Meike Chemical Co., Ltd. is an important BDO supplier and leading enterprise in China and the world. It has rich experience in the construction and operation of BDO factories and can provide strong technical and management support for the implementation of this project.
