As April 2022 arrived, Hebei Fengmei Coking Company strengthened its production organization, focused on various production and operational targets, and made every effort to boost production and efficiency. For the production of methanol from coke oven gas, additional methanol-coke oven gas compressors are installed to ensure an adequate supply of gas for methanol production, thereby increasing the synthesis pressure and ensuring stable and high yields of methanol. In addition, make preparations for the pilot production of ammonia from methanol off-gas. Conduct a pre-driving checklist, approve the planned measures in advance, carry out employee training and on-site equipment calibration, to prepare for the trial production of ammonia synthesis. At Fengmei Coking, 80,000 tons of ammonia are produced by utilizing the vent gas emitted during the methanol production process from coke oven gas; hydrogen is generated through pressure swing adsorption technology provided by the Southwest Research Institute, and this hydrogen is then combined with nitrogen produced by air separation to produce ammonia. Project Overview: The Hebei Fengmei Coking Project, with an annual production capacity of 80,000 tons of synthetic ammonia, officially commenced construction on November 28, 2019. The project covers an area of approximately 57,100 square meters, has a construction period of 12 months, and its total investment is estimated at 95.88 million yuan. The construction work includes the installation of equipment such as liquid ammonia storage tanks, ammonia synthesis units, compressors, and pressure swing adsorption systems, as well as the development of utility systems. The synthetic ammonia plant uses the off-gases from the methanol production process and nitrogen from the air separation system as primary raw materials to produce liquid ammonia. Release gas is a low-value gas that does not participate in the reaction during methanol production; it is currently burned back in the furnace ； Nitrogen is a gas produced internally in the air separation unit, and most of it is vented. The ammonia synthesis project makes efficient use of these two types of gases, which not only helps save energy and protect the environment but also generates benefits; it truly represents the transformation of waste into treasure, and is a typical example of green development. At present, high-value-added development projects such as advanced tar processing, needle coke, ethanol, ethylene glycol, high-power graphite electrodes, and LNG have entered the stage of substantive planning. Fengmei Coking Co., Ltd. was established in 2007, and it has a wholly-owned subsidiary named Qingdao Jifeng Huixiang International Logistics Co., Ltd. It mainly produces semi-high-grade metallurgical coke, as well as chemical products such as methanol, coal tar, ammonium sulfate, and crude benzene. The annual production capacity for coke is 1.6 million tons, while the annual output of methanol reaches 200,000 tons. The product is sold in nearly ten provinces and regions across the Northeast, North China, East China, South China, and Southwest China; coke is exported to India and Vietnam, while coke powder and coke pellets are exported to South Korea. The company is committed to expanding the coal chemical industry chain, and has developed into a new type of coal chemical manufacturing enterprise that integrates research, development, and production, while continuously moving toward larger scales, higher quality standards, and more organized industrial clusters.
