First Lifting of Heavy Equipment for 1.8 Million Tonnes Methanol-to-Olefins Project in Qinghai Author/Source: Date: 12-22-2017 Clicks: 14 On December 11, the polypropylene unit of the EPC project carried out by Sinopec Shanghai Engineering Co., Ltd. – the Qinghai Damei Coal Industry waste gas utilization to produce olefins project – saw the first lifting of its heavy equipment. The second reactor in the reactive polymerization unit of the polypropylene plant has a large capacity, with an overall height of 40.65 meters. At 9:32 a.m. that day, the second reactor in the reaction polymerization unit of the polypropylene plant was slowly lifted using a 750-ton crane; once it was in an upright position, it was moved horizontally to the pipe rack area. At 10:32, the reactor was smoothly and precisely placed on the foundation pad, marking the successful completion of the first large-scale lifting operation for the Qinghai Damei project. On November 10, a key milestone was reached in the EPC general contracting project of Sinopec Shanghai Engineering Co., Ltd. – the 400,000 tons per year polypropylene plant at the Qinghai Damei project: the main structure of the extrusion granulation building was completed. The main structure of the extrusion granulation plant has been completed. It is reported that the civil construction of this plant is a key task within one of the critical pathways of the polypropylene production facility; it features a reinforced concrete frame structure with four floors above ground, and an overall height of 45.2 meters. It represents the single building project with the largest volume of construction work in the polypropylene production facility. The construction of the Qinghai Damei Coal Industry’s project for the comprehensive utilization of exhaust gases to produce olefins involves an investment of 12.7 billion yuan. The project is located in the West Area of the Ganhe Industrial Park, within the Xining Economic and Technological Development Zone in Qinghai Province. Construction began on March 23rd, with a capacity of 1.8 million tons per year for methanol-to-olefins production, 300,000 tons per year for polyethylene production, and 400,000 tons per year for polypropylene production. The project also includes necessary utility systems, auxiliary facilities, and external infrastructure. The project uses MTO-grade methanol as raw material, and through production units such as methanol to olefins, olefin conversion, MTBE/1-butene, polyethylene, and polypropylene, it produces polyethylene and polypropylene products, with MTBE and C4/C6 as by-products. The MTO combined unit in this project utilizes the DMTO technology developed by the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and was EPC-general contracted by Sinopec Luoyang Engineering Co., Ltd. It is reported that part of the regional methanol resources used in this project come from a project that produces methanol from waste gases generated in the area’s smelting operations. The construction of this project contributes to the expansion of the industrial chain that links smelting waste gases, methanol, and polyolefins; hence, the project was named the Qinghai Damei Ganhe Industrial Park Waste Gas Comprehensive Utilization Project for Polyolefin Production. This project does not directly use the smelting waste gases from the park to produce methanol. The methanol used as raw material for this project comes from Qinghai Guilu Chemical Co., Ltd. (1 million tons per year), Western Petrochemical Co., Ltd. (600,000 tons per year), and the Golmud Refinery of CNPC’s Qinghai Oilfield (300,000 tons per year); agreements for the supply of methanol have been signed with all of these parties.
