Recently, Ningxia Coal industry 100kt/a ethylene-vinyl acetate copolymer (EVA) project site leveling project commissioned by the coal to oil chemical engineering construction headquarters officially started, marking the official start of the construction of EVA project.
The total investment of the project is estimated at 2.37 billion yuan, and the EVA products covering photovoltaic film, cable material, foamed shoe material, hot melt adhesive, agricultural film and other fields are produced by using the ethylene and public works rich in olefin phase II. After the implementation of the project, the demand for ethylene will increase, and the processing volume of naphtha can be increased, which can not only solve the problem of the imbalance of the ethylene plant of the second phase of the olefin project, but also solve the problem of the imbalance of the load of each process unit, but also realize the differentiation and high-end of polyethylene products, and promote the in-depth development of the polyolefin industry.
It is reported that the EVA project is scheduled to be put into production in December 2025 and is intended to use ExxonMobil's kettle process. The main raw materials are ethylene from the olefin Phase II project and purchased ethylene acetate, and the auxiliary materials mainly include isobutene, n-butane, iso-alkane solvent oil and iso-dodecane solvent. 9 grades of EVA products are produced.
