Environmental impact assessment approved for Guanggang’s 2,500 standard cubic meters per hour methanol-to-hydrogen project

Thread Content

On August 24, the environmental impact assessment document for the hydrogen production capacity expansion project of Guanggang Gas (Guangzhou) Co., Ltd. was approved. The hydrogen production capacity expansion project is located at No. 5 Honggang Road, Steel Industry Base, Wanqingsha Town, Nansha District, Guangzhou. It is primarily engaged in the production and sale of industrial gases such as oxygen, nitrogen, argon, and hydrogen. The original plant was equipped with 1 air separation unit with a capacity of 10,000 standard cubic meters per hour, 1 gas liquefaction unit with a production capacity of 480 tons per day, and 1 all-liquid air separation unit with a production capacity of 600 tons per day. There were also two hydrogen production units with capacities of 1,000 standard cubic meters per hour and 300 standard cubic meters per hour respectively ； The existing plant produces 119.16 million cubic meters of oxygen per year, 236.32 million cubic meters of nitrogen per year, 4.13 million cubic meters of argon per year, and 10.296 million cubic meters of hydrogen per year. It is also equipped with storage and filling systems for helium as well as high-end helium-based mixtures. The original project site covered a total area of 99,223 square meters, employed 230 people, and did not have a cafeteria or dormitories. To facilitate its development, the company carries out renovations and expansions within its existing plant premises; such projects do not result in an increase in the land area occupied ； The existing methanol-to-hydrogen plant with a capacity of 300 standard cubic meters per hour, along with its supporting facilities, is to be demolished. A new methanol-to-hydrogen plant with a capacity of 2,500 standard cubic meters per hour will be constructed; the methanol conversion and PSA hydrogen production units, the heat transfer oil system, the demineralized water system, the electrical system, and 2 hydrogen buffer tanks will all be new, while the other supporting facilities will be upgraded using the existing ones, with the existing methanol storage tanks being utilized as well ； Plan to modify the existing hydrogen filling system ； It is planned to construct a hydrogen pipeline approximately 300 meters long, with a pipe diameter of DN80, a design pressure of 1.5 MPa, and an operating pressure of 1.0 MPa. This pipeline will connect the buffer tank of the methanol-to-hydrogen plant with a capacity of 2500 standard cubic meters per hour to Guangzhou JFE Steel Plate Co., Ltd. The renovation and expansion project will not result in any new employees, and the working system remains unchanged.
