! The coking project of Pingyao Coal Chemical Group, which involves an investment of 3.8 billion yuan and a production capacity of 1.94 million tons, has entered the production phase. Recently, the upgrade project for the 6.25 m rammed coke ovens at Pingyao Coal Chemical Group has entered production, with these 6.25 m rammed coke ovens officially taking over from the 4.3 m coke ovens that were shut down. This project features China’s first coke oven enclosure system equipped with a ramming coal-loading and coke pushing integrated machine. It employs artificial intelligence for the automatic distribution of flue gas flow, as well as advanced technologies such as automatic calculation and analysis of losses during dry quenching of coke, recovery and reuse of nitrogen-rich gases, evaporation and crystallization of concentrated brine, and the use of off-gases from acid production and phenol-cyanide wastewater in low-nitrogen combustion processes. These measures enable annual reductions of 2,500 tons of dust emissions, 2,400 tons of sulfur dioxide emissions, and 735 tons of nitrogen oxide emissions. Fan Peigang, the engineering supervisor in the coking workshop of Pingyao No.1 Coal Mine Coking Co., Ltd., said that the project is equipped with China’s first fully enclosed facility using SCP machines, which enables dust- and smoke-free operations; VOCs are controlled throughout the entire process. The project also features improved wastewater treatment facilities that achieve \"zero wastewater discharge\". It is reported that once Phase 1 of the project comes online, it will be able to produce 1.34 million tons of coke, 82,000 tons of tar, 20,000 tons of crude benzene, 19,000 tons of sulfuric acid, and 15,000 tons of ammonium sulfate per year. It will also be capable of producing 125,700 tons of liquefied natural gas and generating 172 million kWh of electricity. This will result in an annual increase in output value of 4 billion yuan, profits and taxes exceeding 1 billion yuan, as well as the creation of over 1,000 new jobs. On October 18, 2023, Pingyao Coal Chemical Group held a grand ceremony to mark the retirement of 600,000-ton capacity 4.3-meter coke ovens. After the 600,000-ton 4.3-meter coke ovens were taken out of service, they were replaced by 6.25-meter rammed coke ovens that combine first-class design, processes, equipment, environmental protection measures, and management. A total investment of 3.8 billion yuan has been poured into this project, with an approved production capacity of 1.94 million tons per year (1.34 million tons per year in the first phase and 600,000 tons per year in the second phase). It is now in the trial production stage; once operational, the project will generate an additional output value of 5.8 billion yuan and profits and taxes in excess of 1.5 billion yuan ； It can provide over 1,000 job opportunities, and ensure centralized heating for more than 50,000 households covering an area of over 5 million square meters during winter ； It can reduce smoke and dust emissions by 2,500 tons, sulfur dioxide emissions by 2,400 tons, and nitrogen oxide emissions by 735 tons, achieving a reduction in the total amount of air pollutants emitted. The commissioning of the new project will surely usher in a new chapter of high-quality development for Pingyao Coal Chemical Group, and it will make further and greater contributions to the economic development of the region, the well-being of its residents, and the improvement of environmental quality.
