Successful First Commissioning of Cornell MTO Unit Under Huisheng Engineering’s EPC Contract Author/Source: Yahuacoking Chemical Industry Date: April 22, 2020 Clicks: 56 On April 20, 2020, the 300,000-ton-per-year methanol-to-olefins unit of the first phase of Cornell Chemical Industry Co., Ltd.’s 600,000-ton-per-year methanol-to-olefins production project, which was technically supported by Huisheng Engineering (stock code: 2236.HK) and under its EPC contract, was successfully commissioned, producing qualified ethylene and propylene products! As the first project of a large-scale petrochemical enterprise to begin operation during the national pandemic prevention and control period, the plant started feeding materials at 08:18 on April 15; qualified propylene product was produced at 07:00 on April 18, and qualified ethylene product was produced at 04:00 on April 20. This facility adopts a combined technology approach that integrates UOP’s MTO/OCP reaction technology with Hyosung Engineering’s olefin separation technology centered on \"pre-cutting + oil absorption\", with Hyosung Engineering providing the EPC turnkey service. The technical approach that combines UOP’s MTO/OCP reaction technology with Hyosung Engineering’s “pre-cutting + oil absorption” method represents the most advanced technology in the global MTO industry, offering advantages such as lower consumption of methanol per ton of olefins and lower catalyst usage ； It is also the tenth commercial MTO unit to employ Hysol olefin separation technology. The successful commissioning of this plant with the feedstock addition once again demonstrates the reliability of Huisheng Engineering’s olefin separation technology as well as Huisheng Engineering’s expertise in the field of MTO engineering. Key Milestones: In July 2016, Huisheng Engineering signed an EPC contract for the first phase of this project, which involves a 300,000 tons per year methanol-to-olefins plant, with Cornell Chemicals. It also signed contracts for the licensing of proprietary technology related to the olefin separation unit as well as for the development of the process packages. Huisheng Engineering is responsible for the overall design, procurement, and construction of the methanol-to-olefins reaction and concentration unit, the olefins separation unit, the olefins cracking unit, as well as some of the auxiliary facilities in this project. In the same month, the on-site civil engineering work officially commenced. In October 2016, Honeywell UOP and Cornell Chemical signed a technology licensing agreement for the first phase of this project, which involves a 300,000-ton-per-year methanol-to-olefins plant using MTO+OCP technology. In September 2017, the handover ceremony for the first phase of this project, which involves a 300,000-ton/year methanol-to-olefins plant and was EPC-general contracted by Huisheng Engineering, was successfully held at the project site. On April 20, 2020, the first phase of this project, consisting of a 300,000 tons per year methanol-to-olefins plant, was successfully commissioned for the first time.
