Trial production of Pujie energy carbon-4 comprehensive utilization project

On October 10, the reporter learned from Shaanxi Coal Group Pujie Energy Chemical Company that the company's C4 comprehensive utilization project entered the trial production stage and is expected to be put into production
at the end of October.
At that time, Pujie Energy can produce new products with high added value of 1-butene through C₄ comprehensive utilization to achieve self-production and self-use
.

It is reported that the C₄ comprehensive utilization project uses the by-product mixed C₄ of Pujie energy methanol to low-carbon olefin (DMTO) plant as raw material, and the annual output of nearly 40,000 tons of 1-butene is selected through hydrogenation, 1-butene
refining, olefin isomerization and other processes.

"1-Butene is a polyethylene synthetic comonomer that needs to be purchased about 30,000 tons
per year.
The mixed C₄ by-product of the DMTO device is all exported
.
Through comprehensive utilization, the 1-butene we produce just meets the production needs and realizes self-production and self-consumption
.
Xie Botao, deputy general manager of Pujie Energy Chemical Company, said that after the C₄ comprehensive utilization project is put into operation, it is expected to increase the annual output value of 650 million yuan and realize a profit of about 56 million yuan, which can not only reduce the production cost of polyethylene, but also achieve carbon reduction and consumption
reduction of the device.

As the main of the coal-to-olefin industry chain in Shaanxi Province, in addition to the C₄ comprehensive utilization project, Pujie Energy Chemical has also planned a hydrogen energy comprehensive utilization project, polyolefin resin modification research and application project, 40,000 tons/year ultra-high relative molecular weight polyethylene project, 100,000 tons/year carbon dioxide-based degradable plastics project, etc.
, to further enhance the core competitiveness
of the enterprise.
