This project utilizes the carbon dioxide-rich tail gas from the PSA decarbonization process of a methanol-to-hydrogen plant as feedstock. Upon commissioning, it will achieve an annual production capacity of 200,000 metric tons of liquid carbon dioxide. Employing a process of pre-cooling, compression, and multi-stage liquefaction and purification, the project produces liquid carbon dioxide that meets the premium-grade requirements of the GB/T 6052-2011 standard for industrial liquid carbon dioxide (with a carbon dioxide purity of ≥99.9%). Upon completion, the project is expected to generate annual sales revenue of approximately 80 million yuan. The project commenced operations successfully in early 2022, with all performance indicators exceeding design and contractual specifications.
