on december 19, 2022, lianhong xinke issued an announcement, indicating the approval of the proposal on the investment and development of integrated projects for new energy materials and biodegradable materials by its controlling subsidiary, lianhong gerun (shandong) new materials co., ltd. the detailed information of the project is as follows:
construction company: lianhong gerun (shandong) new materials co., ltd
construction site: lunan high tech chemical industrial park, tengzhou city, shandong province, located in the western and southern parts of the lianhong new materials technology co., ltd
land area: 1694 acres of newly added land (approximately 425 acres on the west side and 1269 acres on the south side)
labor quota: 553 people
project investment: 12.5 billion yuan
construction content: after purchase of feedstocks such as methanol, vinyl acetate, isopropylbenzene, co2 rich gas, synthesis gas, and mixed carbon four, the methanol to olefin unit is adopted to produce polymer grade ethylene and polymer grade propylene. qualified high-end chemical products such as eva, ppc, and epoxypropane are produced through eva, epoxypropane, and ppc units. the main production facilities include a 1.3 million ton/year dmto unit (including a 90,000 ton/year occ unit) and a 200,000 ton/year eva unit, 300,000 tons/year po equipment, 50000 tons/year ppc equipment, overall plan storage and transportation, supporting public works and auxiliary production facilities, environmental protection and governance facilities, etc.

among them, dmto device of methanol to olefin unit adopts dmto patented process technology jointly developed by dalian institute of chemical physics, syn energy technology co., ltd. and sinopec luoyang engineering co., ltd. through comparison. the olefin separation unit has been compared and selected taking the pre-deethane olefin separation process technology by sinopec luoyang engineering co., ltd.
