According to the \"Announcement on the Winner of the Bid for the Design of the Project to Produce 320,000 tons per year of liquid ammonia from process exhaust gases and to achieve comprehensive utilization of carbon\" issued by Henan Longyu Coal Chemical Co., Ltd., Aerospace Changzheng Chemical Engineering Co., Ltd. announced on November 12, 2025, that it had won the bid for this project undertaken by Henan Longyu Coal Chemical Co., Ltd., with the bid amount being 2.06 million yuan. Project Name: Project for the Production of 320,000 tons/year of liquid ammonia and comprehensive utilization of carbon from process tail gases at Henan Longyu Coal Chemical Co., Ltd.Construction Location: Industrial reserve land within the park, south of the office building of Henan Longyu Coal Chemical Co., Ltd., Yongcheng Economic and Technological Development Zone.
Constructor: Henan Longyu Coal Chemical Co., Ltd.
Project Overview: This project involves an additional land area of 6.32 hectares, with a total investment of 350 million yuan. It includes the construction of facilities for compression, ammonia synthesis, industrial ammonium carbonate production, and product storage. The project aims to convert process tail gases and vented nitrogen from coal chemical plants into liquid ammonia. Additionally, it utilizes carbon dioxide emitted from existing facilities to produce industrial-grade ammonium bicarbonate, while also generating steam as a by-product. Achieve the resource utilization of process exhaust gases, their low-carbon and green comprehensive utilization, as well as carbon dioxide emission reduction. The project produces 320,000 tons of liquid ammonia and 400,000 tons of ammonium bicarbonate per year.
