After 25 months of construction, Xinjiang Tianli High-tech’s 200,000 tons/year EVA device achieved CCCC
Thread Content
According to Huanqiu Engineering Company, at 11:30 a.m. on June 30, the signing ceremony for the delivery of China Petroleum's first EVA device, Xinjiang Tianli High-tech's 200,000 tons/year EVA device, was grandly held at the project construction site. This marked that the project achieved high-level and comprehensive delivery, and the project construction officially entered the overall linkage commissioning stage.
The Tianli High-tech EVA project is the first EVA device of PetroChina. It is a key project of China National Petroleum Corporation to support the transformation and upgrading of local state-owned enterprises in Dushanzi. It is also a supporting project of Dushanzi Petrochemical Company's light hydrocarbon refining and ethylene optimization and adjustment project. It is also the hope project and life project of Tianli High-tech Petrochemical. It plays a positive role in giving full play to geographical and resource advantages, promoting joint and coordinated development of enterprises and localities, and supporting Xinjiang's economic construction. The total investment of the project is 2.462 billion yuan, with a total of 660 sets of equipment, more than 9,100 tons of steel structure, 52,000 cubic meters of concrete, 110 kilometers of process pipelines, and a maximum design pressure of 360 MPa. The relevant domestic standard system is incomplete, and the equipment operating conditions are harsh. It puts forward extremely high requirements for design, procurement, and construction commissioning. It is a special engineering project with complex technology.
The device adopts Basell's LUPOTECH T tubular reactor technology, using peroxide as the initiator and injecting it into different areas of the reactor at four points. The operating pressure of the pulse reactor is as high as 300MPa. It has the characteristics of wide product range, short brand switching time, less transition materials, and high process operation flexibility. The product structure is reasonable and can switch to produce different brands of low-density polyethylene (LDPE) homopolymer resin and ethylene-vinyl acetate copolymer resin (EVA) on one production line.
