Meeting held to assess the 300,000 tons/year methanol project associated with Qianxi Chemical Industry / Author/Source: Guizhou Yueneng Investment Co., Ltd. Date: July 5, 2019. Clicks: 1. On June 11, Qianxi Chemical Industry held a meeting to evaluate this 300,000 tons/year methanol project; experts involved in the assessment including Yang Qishen, Secretary-General of the Henan Chemical Industry Association, Yang Qingsong, Chairman of Guizhou Yueneng, and engineering staff from the Lanzhou branch of the Aerospace Engineering Corporation, all attended the meeting. At the meeting, Yang Qingsong delivered a speech first, and together with the experts, they listened to a report on the feasibility study and progress of Qianxi Chemical’s 300,000 tons per year methanol project. They analyzed and evaluated the project’s prospects, economic viability, technical feasibility, and construction approaches, thereby forming corresponding opinions. It is reported that the gasification unit of Qianxi Chemical’s project for producing 300,000 tons of coal-based ethylene glycol per year is designed to operate using three space-type pressurized coal gasifiers, with two in use and one as a backup, to generate crude syngas for the production of ethylene glycol. Currently, the overall performance of the gasification furnace is stable, enabling it to meet the demands of high-load operation, while its backup furnace is idle. In order to maximize the production potential of the ethylene glycol plant, after thorough research and analysis, the company plans to rely on the backup gasifier and the utility systems associated with the ethylene glycol project, and to add another methanol plant with an annual capacity of 300,000 tons (to serve as a facility for producing the methanol required as raw material for ethylene glycol production). By producing methanol using the excess syngas while also manufacturing ethylene glycol, it is possible to operate all three gasifiers simultaneously. This approach enables comprehensive utilization of the existing plant’s excess gas production capacity and utility resources, thereby maximizing the production potential of the existing facilities and improving the asset utilization rate of the ethylene glycol plant. By utilizing the space reserved on-site, no additional land for construction is required, and it is possible to carry out production by making comprehensive use of the excess capacity of utilities such as water, electricity, steam, and gas generation available in the existing ethylene glycol plant. This project plans to adopt domestic sulfur-resistant isothermal shift technology, low-temperature methanol washing for desulfurization and decarbonization, methanol synthesis technology, and four-column distillation technology. The process technology route is mature, advanced, and rational, featuring a short process flow and low energy consumption. The main construction activities include transformation and expansion upgrades, desulfurization and decarbonization upgrades, ice machines, methanol synthesis, distillation, syngas compression, and the addition of a new air separation unit ； As well as utility and auxiliary facilities, including the main substation, water supply and drainage networks, circulating water stations, desalination stations, process deaeration tanks and feed water pumps, process and heating external pipelines, general transportation systems, control rooms, and other supporting facilities.
