The 500,000-ton methanol-to-ethanol project plant in Anhui passed the framework review
Thread Content
The expert review meeting on the framework of the carbonylation reactor and the methyl acetate reactor for the ethanol production unit in Anhui CarbonXin Technology Co., Ltd.’s methanol comprehensive utilization project, which was EPC-general contracted by Beijing Petrochemical Engineering Co., Ltd., was held successfully and passed the evaluation, creating favorable conditions for the subsequent construction of the main concrete structures. It is reported that the construction of the concrete structures for the carbonylation reactor frame and the methyl acetate reactor frame constitutes the critical path in the civil engineering phase of this project. Moreover, the upper concrete structures involve concrete formwork support work with a high degree of risk, requiring expert evaluation. The project department will carry out the installation of high-support formwork scaffolding on a full scale to ensure the timely and smooth progress of the upper concrete structure.
Anhui Carbonxin Technology Co., Ltd. is a wholly-owned subsidiary of Huaibei Mining Co., Ltd. Huaibei Mining is a source of high-quality coal in East China. Its main business is coal production, and coal chemical processing, as one of the important ways to extend the industrial chain and promote the sustainable development of coal enterprises, has seen rapid growth within the Huaibei Mining Group in recent years. Building on the existing methanol production facilities, CarbonXin Technology Co., Ltd. plans to construct a new ethanol production plant with an annual capacity of 600,000 tons in the Linhuan Industrial Park, utilizing the existing methanol production capacity. This plant will be equipped with powder gasification units, purification units, as well as CO and H2 separation units. On December 20, the trial production of the methanol project at Anhui Carbonxin Technology Co., Ltd. and the official commencement ceremony for the EPC work of the ethanol project were held grandly at the site of Anhui Carbonxin’s coke oven gas comprehensive utilization project. The successful completion of this ceremony marks the practical completion of the project with an annual production capacity of 500,000 tons of methanol, enabling it to enter the trial production phase; at the same time, the project with an annual production capacity of 600,000 tons of ethanol has officially commenced operations.
The 500,000 tons per year methanol production project using comprehensive utilization of coke oven gas is based on coal as raw material; it makes use of the hydrogen-rich gas generated during the methanol production process at Linhuan Coking Co., Ltd., and supplements carbon through gasification, with a designed annual output of 500,000 tons of methanol. The project is located within the Anhui (Huaibei) New Coal Chemical Synthesis Materials Base (formerly the Huanhuan Industrial Park in Huaibei, Anhui). It is a key project under Anhui Province’s “861 Action Plan”, and it represents the first project to be launched as part of the “Coal Chemistry-Salt Chemistry Integration” initiative, which aims to revitalize the economy of northern Anhui. Anhui Carbonxin Technology Co., Ltd. is a wholly-owned subsidiary of Huaibei Mining Group. The comprehensive utilization project for coke oven gas is located in the Linhuan Industrial Park, Hancun Town, Suixi County, Huaibei City, Anhui Province. The 500,000-ton/year project for the comprehensive utilization of coke oven gas to produce methanol is one of the third-phase projects within the “Comprehensive Utilization Project for Coke Oven Gas” planned and implemented by Huaibei Mining Group. This project aims to make full use of the hydrogen-rich off-gases from the existing two 400,000-ton/year methanol production units at the Linhuan coking plant; by adding carbon through coal-to-gas conversion, an additional unit with an annual production capacity of 500,000 tons of methanol will be established. In this way, an overall annual production capacity of 900,000 tons of methanol will be achieved, which will serve as raw material for extending the downstream olefin industry chain in Anhui (Huaibei)’s new coal chemical synthesis materials base. The base is a high-tech industrial park whose strategic development directions are coal-based synthetic materials and a circular economy; it serves as an important platform for Huaibei City to promote the transformation of its resource-based economy.
