Clicks: 41. As of June 5, the MTO unit of Shenhua Coal-to-Oil Chemicals Company’s Xinjiang coal-based new materials project was able to process 242.7 tons of methanol per hour, thus operating at 100% capacity steadily for the first time. The MTO unit of this project utilizes the SHMTO patented technology independently developed by Shenhua Coal-to-Oil Chemical Co., Ltd. The process package was developed through collaboration between this company and the East China Design Branch of China National Petroleum Engineering Corporation; it features a low reaction space velocity, as well as high carbon content in both the spent catalyst and the regenerated catalyst. Special catalysts for the conversion of methanol into olefins are used, with a designed processing capacity of 1.833 million tons per year of methanol (in pure form), yielding 600,000 tons per year of olefin products (ethylene + propylene). The design operating range is 60–110%, and the annual operating hours are 8,000 hours. The unit consists mainly of a reaction-regeneration system, a quench water washing-stripping system, as well as CO-waste heat boilers and waste heat steam generation systems. After the major maintenance, the MTO unit started up successfully on the first attempt and its load was steadily increased to 90%; following subsequent adjustments, it achieved stable operation at 100% full load using the SHMTO process for the first time. The full-load, stable operation of the MTO unit represents a milestone-like, historically significant moment for the SHMTO process, laying a solid foundation for the project’s ‘stable, continuous, efficient’ operation. Shenhua Xinjiang Coal-based New Materials Project: The original designed production capacity for this project was 300,000 tons per year of PE and 380,000 tons per year of PP; the actual production capacity is 270,000 tons per year of PE. It mainly produces LDPE products such as 2426H, 2426K, and 2426F ； 450,000 tons per year of PP, of which 40,000 tons are produced using recycled materials as raw material, mainly yielding K8003 and S1003. The project was invested and constructed by the Xinjiang Coal Chemical Branch of China Shenhua Coal-to-Oil Chemical Co., Ltd. (the Shenhua Xinjiang Coal Chemical Branch was renamed as a subsidiary of Shenhua Group in Xinjiang on April 10, 2016). Construction on the project officially began in July 2013, and it was largely completed by 2016. On May 21, 2016, the gasification unit achieved successful first-time feeding ； On June 17, the methanol synthesis unit began producing methanol of MTO grade after feeding the raw materials ； On September 23, the MTO unit was successfully commissioned ； On October 3, polyolefin products were successfully produced.
