Construction of Xuzhou Longxingtai’s 2.6 million tons per year catalytic concentrated ammonia production project begins Author/Source: Chuangju Technology Date: 2021-12-01 Clicks: 6 On November 18, the project to produce 2.6 million tons per year of catalytic concentrated ammonia, undertaken by Tianjin Chuangju Technology Co., Ltd. (hereinafter referred to as “Chuangju Technology”), at Xuzhou Longxingtai Energy Technology Co., Ltd., officially commenced construction. The process parameters for the 2.6 million tons per year coking energy comprehensive utilization project built by Xuzhou Longxingtai Energy Co., Ltd. include coal preparation, 4×65-hole 2.6 million tons per year 6.25m rammed coke ovens, cold drumming, desulfurization, acid production, ammonium sulfate synthesis, benzene extraction, and acid removal/ammonia distillation. The auxiliary facilities include a main power transformer, dry quenching systems, a power plant, circulating water systems, production fire-fighting water systems, refrigeration units, sewage treatment systems, air and nitrogen supply systems, coke screening and storage facilities, and surface dust removal stations. As for the utilization of coal gas, the project includes 300,000 tons per year of methanol production and 100,000 tons per year of synthetic ammonia production. This project utilizes innovative patented technologies – the \"process package technology for producing 20% high-concentration ammonia water from excess ammonia water\" and the \"new type of high-efficiency jet-type tray technology\" – to concentrate the ammonia water produced. The traditional ammonia distillation process for residual ammonia water can only produce ammonia water with a concentration of around 8%, whereas the proprietary technology developed by Chuangju Technology enables the production of concentrated ammonia water with a concentration of over 20%; this concentrated ammonia water can be used for flue gas denitration. On the other hand, the production of 20% concentrated ammonia solution results in a reduction of more than 60% in the total amount of ammonia produced, compared to the approximately 8% ammonia obtained through conventional ammonia distillation methods. This significantly reduces the amount of ammonia required in the desulfurization process. By using concentrated ammonia solution, ammonia can be supplied to the desulfurization system while simultaneously eliminating the problem of excess liquid in the desulfurization solution. Based on current market conditions, it costs 200-300 yuan to treat one cubic meter of desulfurization wastewater. The application of this technology not only addresses environmental protection issues but also **reduces production costs.
