In the "Environmental Ammonia Industry Access Requirements (Draft for Comment)" issued by the Ministry of Industry and Information Technology on June 1, energy access conditions are one of the important contents. The industry believes that the current level of energy consumption for synthetic ammonia production in domestic companies is uneven, with a large gap between the high and low levels. Next, many companies will accelerate energy-saving technological transformation to meet the requirements of the new situation.
It is understood that access conditions set higher energy consumption, pollutant emissions and production safety indicators. For synthetic ammonia construction projects that do not meet the access conditions, the environmental protection department must not go through the formalities for environmental protection examination and approval, financial institutions must not provide credit, and the power supply department should stop supplying electricity in accordance with the law; synthetic ammonia construction projects should reach energy consumption and pollutant discharge targets within 12 months of production. Ammonia enterprises that fail to meet waste discharge standards, have major safety accidents, and have an average annual ton of ammonia energy above a limit value should withdraw as backward production capacity.
At present, there is a large gap in energy consumption between domestic enterprises and enterprises. According to report, the most advanced energy-consumption enterprise of synthetic ammonia plants using anthracite as raw materials is Henan Xinlianxin Chemical Fertilizer Co., Ltd., with a total energy consumption of 1374 kg of standard coal per ton of ammonia, and 2137 kg of standard coal for the worst company; The most advanced energy-consumption enterprise of synthetic ammonia plants (including brown coal) as raw materials is Jiangsu Linggu Chemical Co., Ltd., with an integrated energy consumption per ton of ammonia of 1,631 kg of standard coal, and the worst enterprise is 2,223 kg of standard coal. People in the industry believe that backward companies will increase efforts in energy-saving technological transformation in the face of pressure.
Hunan Anxuan High-tech Co., Ltd. is a company that supplies synthetic ammonia technology and equipment . Dai Fengyu, deputy general manager of the company, told reporters that the introduction of access conditions may urge some high energy-consuming enterprises to carry out safety and energy saving technologies. Transformation.
According to the reporter's understanding, for large companies, although they have basically met the requirements in the "access conditions" in terms of energy consumption, they also hope that the access conditions will be higher and the companies will be confined to further energy conservation. Wang Xiang, director of the technology research and development center of Shanxi Tianze Coal Chemical Group Co., Ltd., proposed to increase the access value of energy consumption limits for the three kinds of raw materials for ammonia synthesis products to the following standards: High quality anthracite lump coal ≤ 1300 kg standard coal/ton, non-high quality anthracite coal , coke, coal ≤ 1500 kg standard coal / ton, natural gas, coke oven gas ≤ 1000 kg standard coal / ton.
