[Haichuan Chemical News] Construction of key facilities for Anhui Carbonxin’s 500,000-ton/year methanol production project from coke oven gas has begun

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. A contract worth 1.367 billion yuan was signed with Donghua Technology, and the construction period is 22 months. The scope of the contract includes a turnkey EPC project covering the 2,000 tons/day powder gasification unit, the 500,000 tons/year methanol synthesis unit, as well as related auxiliary facilities. The 500,000 tons per year methanol production project via comprehensive utilization of coke oven gas is one of the third-phase projects under the \"Comprehensive Utilization of Coke Oven Gas Project\" planned and implemented by Huaibei Mining Group. It aims to make full use of the hydrogen-rich off-gases from the existing two 400,000 tons per year methanol production units at Linhuan Coking Plant; by adding carbon through coal-to-gas conversion, an additional unit with a capacity of 500,000 tons per year of methanol production will be established. This will result in an overall annual methanol production capacity of 900,000 tons, 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.

It is one of the phases of the \"Comprehensive Utilization Project for Coke Oven Gas\"; the aim is to make full use of the hydrogen-rich off-gases from the existing two methanol production units at Linhuan Coking with a capacity of 400,000 tons each. By adding carbon through coal-to-gas conversion, an additional methanol production unit with an annual capacity of 500,000 tons will be established, resulting in an overall annual methanol production capacity of 900,000 tons. -- According to the promotional materials, the existing hydrogen-rich off-gases will be utilized, which represents an element of resource utilization, while at the same time another coal-to-gas unit will be added.

There are currently hydrogen-rich off-gases from two methanol plants with a capacity of 400,000 tons each, as well as a powder coal gasification plant with a capacity of 2,000 tons per day and a methanol plant with an annual capacity of 500,000 tons. It seems that the main components are still the gasification plants and methanol plants. The concept of comprehensive utilization of coke oven gas can be applied here, but can such small-scale methanol plants be profitable?

I’m not sure about that; it seems to be designed by Donghua Technology

Anhui is essentially the domain of Sanyuan; Zhong’an was originally also the overall designer for Sanyuan. It was only with the strong involvement of Sinopec that the design work was assigned to them.
