The project is based on an efficient carbon dioxide capture process and adopts low-temperature liquefaction and distillation purification technologies. It relies on the surplus carbon dioxide in the production process of the ammonia urea unit of Jinjiang Chemical to capture, purify, and liquefy, and develops low-cost carbon capture technology optimization and improvement for high concentration carbon dioxide capture, forming a demonstration project and ultimately achieving industry-leading collection costs.

The project officially started construction in September 2022, with a total investment of 84.6186 million yuan. The design scale is 2 x 100000 tons/year industrial liquid carbon dioxide device, with an annual operating hours of 8000 hours and an operating flexibility of 50-110%; The product quality meets the requirements of the national standard (GB/T6052-2011). At present, the first phase of the 100000 ton carbon dioxide capture project has been successfully completed and officially put into operation. There is no industrial “three wastes” discharge during the project production process, which complies with national industrial and environmental policies and has significant environmental and economic benefits.

Jinjiang Chemical is a large-scale coal to urea production enterprise, with a designed urea project scale of 300000 tons of synthetic ammonia and 520000 tons of urea per year, and an annual production of 180000 tons of jinjiang melamine chain extension project. Jinjiang Chemical adheres to the green and low-carbon strategy to lead the overall situation, solidly improves the level of environmental management, and takes the “near zero” emissions of exhaust gas, wastewater, and solid waste as the new goal for the enterprise to actively participate in the “dual carbon” action.
