On July 28, Shandong Hualu Hengsheng Chemical Co.
, Ltd.
(Hualu Hengsheng, 600426) planned to invest 4.
4 billion yuan to build a 120,000-ton/year PBAT degradable plastic and 179,500-ton BDO project
.
Hualu Hengsheng has a cost advantage in entering the ranks of PBAT polymerization.
It has completed a 167,000-ton adipic acid project in February this year and reached the standard and production capacity.
The company's adipic acid product scale has reached an annual output of 340,000 tons, accounting for the proportion of domestic production capacity.
It rose to 12.
5%, entering the first echelon of the industry
.
Proposed start date: 2021
Proposed construction time: 2023
Total investment: 4,428.
17 million yuan
Construction site: Dezhou Canal Hengsheng Chemical Industrial Park, Decheng District, Dezhou City, Shandong Province
Application date: 2021-07-28
Construction scale and content:
After the project is completed and put into operation, the annual output will be 179,500 tons of 1,4 butanediol (BDO), 120,000 tons of butylene terephthalate adipate (PBAT), 50,000 tons of N-methylpyrrolidone (NMP), Production of 5,100 tons of butanol and 13,200 tons of tetrahydrofuran
.
The main processes of the project include: calcium carbide dry method to produce acetylene, methanol air oxidation to produce formaldehyde, acetylenic aldehyde method to produce 1,4 butanediol (BDO), one-step polycondensation method to produce butylene terephthalate adipate (PBAT) , BDO gas-phase dehydrogenation to produce gamma-butyrolactone (GBL), gamma-butyrolactone (GBL) and monomethylamine to catalyze the synthesis of N-methylpyrrolidone (NMP)
.
