Total investment of 675 million yuan! Guizhou Shuicheng Methanol Technical Revamp and Resumption Project advances toward implementation

Total Investment Exceeds 670 Million Yuan; New Methanol Unit to be Supported by a Sound ecological preservation System

This technical renovation and resumption project is located in Shihe Community, Laoyingshan Subdistrict, Shuicheng District, Liupanshui. It is invested in and constructed by Guizhou Energy Shuicheng Coal-Power-Chemical Integration Co., Ltd., with a total investment of 674.894 million yuan, including 57.25 million yuan in ecological preservation investment, accounting to 8.48% of the total.

The project covers an area of 125.2 mu, with the core construction content being a 300,000 tons/year methanol production unit. It includes supporting facilities such as conversion, synthesis, and rectification main production units, as well as utilities like atmosphere separation and methanol tank farms, featuring a mature and complete overall process system.

Regarding raw materials, the project adopts a park tail gaseous resource utilization model. The feedstock gaseous consists of two main sources: coke oven gaseous generated by the existing coal coking project at the base, and calcium carbide furnace gaseous produced by the proposed calcium carbide project, achieving raw material self-sufficiency through the recycling and reuse of manufacturing tail gaseous.

Old Production Capacity Idle to Long Term; Asset Restructuring Initiated in 2023 to Revitalize

The project site possesses a mature foundation to the coal chemical sector. As early as 2007, Guizhou Shuicheng Coal-Power Co., Ltd. planned a coal-power-chemical integration base in Laoyingshan, supporting the construction of methanol, dimethyl ether chemical units, and power workshops. The full set of units was completed in 2014 and passed environmental acceptance in 2016. Affected by market conditions, the project had been in a state of prolonged suspension after completion.

In 2023, in accordance with the unified deployment of Guizhou Province, the locality initiated work to revitalize existing coal chemical resources. A new entity completed asset restructuring to upgrade the site into a coal-coking-chemical-power circular economy base, simultaneously planning core projects such as a 2 million tons/year coal coking project and a 2×660 MW cutting-edge coal power project. In April 2026, this 300,000 tons/year methanol technical renovation and resumption project officially obtained filing procedures.

Though categorized as a "Two-High" Project, environmentally friendly Upgrade Achieved via Circular Model

It is worth noting that while this project is categorized as a "Two-High" (high energy consumption and high discharge) project, it achieves low-carbon and resource-based upgrades through existing technical renovations and manufacturing coupling. The project fully recycles and utilizes two types of manufacturing by-product tail gaseous: coke oven gaseous from coal coking and calcium carbide furnace gaseous from the calcium carbide unit, replacing the traditional route of producing methanol immediately from raw coal.

Through the resource-based reuse of tail gaseous, the locality has successfully constructed a coal coking—coke oven gaseous/calcium carbide furnace gaseous coupling—methanol closed-loop manufacturing chain. This significantly increases the added value of manufacturing by-items, achieves discharge reduction at the source and efficient utilization during the process. While revitalizing idle production capacity and stabilizing the regional coal chemical sector, it efficiently reduces the intensity of regional pollutant releases and promotes the transformation of traditional coal chemical sector towards a circular and environmentally friendly model.
