On April 1, the construction of Furnace No. 1 for dry quenching coke in Henan Jinma Middle East Energy Co., Ltd.’s 1.8 million tons per year coking project commenced successfully. The waste heat power generation project for dry quenching of coke at Henan Jinma Middle East Energy is EPC-general contracted by MCC Coking & Refractory (Dalian) Engineering Technology Co., Ltd. The dry quenching furnace is a key component of dry coke quenching systems; it consists of an upper cone, a pre-storage chamber (ring-shaped air duct), inclined air ducts, and a cooling chamber. Due to its own weight, the coke moves from the upper cone at the top of the furnace through the pre-storage chamber into the cooling chamber. Cold inert gas enters the cooling chamber from the air caps at the bottom, where heat exchange takes place. The cold inert gas then passes through the inclined air ducts into the ring-shaped air ducts, gathers there, undergoes dust removal and purification, and after having its heat recovered in a waste heat boiler, it is reused in the cycle. Dry coke quenching helps reduce water waste and make effective use of the thermal energy of coke, thereby improving the quality of the coke and the production environment. The project involves an investment of 2.36 billion yuan and is located in the fine chemicals industry zone in the southern part of the Huling Industrial Cluster in Jiyuan City. The proposed site for the factory is on the newly allocated land to the east of Jinma Energy’s existing plant. The project uses washed coking coal as raw material to build one set of regenerative top-loading coke ovens with 2×70 chambers and a height of 7.65m, for the production of metallurgical coke and coke oven gas; simultaneously, 3×130t/h dry quenching facilities are also constructed ； The waste gas undergoes purification processes such as condensation and blowing, desulfurization, ammonium sulfide production, and benzene extraction, to recover related chemical products such as tar, ammonium sulfide, and crude benzene.
