On October 22, 2025, the expansion project for coking capacity at Inner Mongolia Heimao Coal Chemical Industry, with a capacity of 1.65 million tons per year, was approved for registration; it is now in the preparatory stage for tendering out the general construction contract. This project is located within the premises of Heimaot Coal Chemical Co., Ltd. in the industrial park of Wulat Houqi County, Bayannur City, Inner Mongolia Autonomous Region, and was invested in and constructed by Inner Mongolia Heimaot Coal Chemical Co., Ltd. Project scale and scope: This project will have an annual production capacity of 1.65 million tons of dry quenched coke; a dry quenching system will be installed as well, and the coke oven gas will be utilized to expand the production capacity of LNG to 100,000 tons per year. Project implementation plan: The project will be constructed in two phases. In the first phase, an output of 1 million tons per year will be achieved using coke ovens with a carbonization chamber height of 7.3 meters and 88 chambers of the rammed-type design; additionally, an LNG production capacity of 100,000 tons per year will be established through the comprehensive utilization of coke oven gas. The second phase has a capacity of 650,000 tons per year, utilizing rammed coke ovens with carbonization chambers 7.3 meters high and 56 holes each. Each coke oven is equipped with devices such as dry quenching of coke, desulfurization and denitrification of coke oven flue gas along with waste heat recovery, waste heat recovery from the rising pipe, a control system for individual carbonization chambers, and dust removal stations on the ground on the machine and coke sides. Construct a coke screening and storage facility, and expand the LNG facility. It is equipped with auxiliary production facilities such as a 10KV electrical room, a circulating water station, and a refrigeration station. The supply of fresh water, demineralized water, compressed air, and nitrogen, as well as office and living facilities, rely on existing infrastructure. The total investment for the project is 1,822.5 million yuan. I. Progress milestones: October 22, 2025 – The project has been registered (project registration completed). II. Types of potential bidders and required qualifications: General contracting and construction services. Key qualifications: Grade 1 qualification for general contracting of building construction projects, or Grade 1 qualification for general contracting of chemical and petroleum engineering projects, plus a work safety license; in addition, there must be experience in carrying out EPC projects for large-scale coking or coal chemical projects over the past 5 years (e.g., China National Chemical Engineering Group, Sinopec Refining & Chemical Engineering Group).
