Recently, Yitai Coal-to-Oil Company’s project for the deep processing of stable light hydrocarbons, with an annual production capacity of 50,000 tons, produced qualified products such as pentane, n-hexane, n-heptane, and light white oil; the purity of n-hexane and n-heptane reached over 99%. It marks the successful commissioning of Yitai Coal-to-Oil Company’s project for the advanced processing of light hydrocarbons. On April 13, the Ordos City Work Safety Supervision Bureau organized experts to review the project’s commissioning plan and conduct on-site inspections, which were all approved successfully; thus, the conditions for hot testing were met. On the afternoon of April 16, the heat transfer oil furnace was successfully ignited, and it entered the furnace heating phase at a temperature below 100°C. Oil boiling, dehydration, and removal of light components began at 8:30 on April 17; by 23:30 that same day, the outlet temperature of the heat transfer oil furnace reached 280°C, marking the completion of the oil boiling process. At 12:12 p.m. on April 19, the fuel transfer unit in the tank farm was started up. At 12:00 on April 20, qualified products such as pentane, n-hexane, n-heptane, and light white oil were produced, with the purity of n-hexane and n-heptane exceeding 99%. It marks the successful trial operation of ITAI’s coal-to-oil company’s project for the advanced processing of light hydrocarbons, with qualified products being produced. At 16:26 on April 21, after increasing the load, the purity of n-heptane reached 99.67%. The 50,000 tons per year deep processing project for stable light hydrocarbons of Inner Mongolia Yitai Coal-to-Oil Co., Ltd. is located within the existing plant area of the Yitai coal-to-oil facility in the Dalu Xin Industrial Park, Jungeer Banner. The scale of this project is to carry out deep processing of 50,000 tons of stable light hydrocarbons per year. The main products include 6 types such as a C4C5 mixture, isohexane, n-hexane, isooctane, n-heptane, and light white oil, with a total investment of 16.3 million yuan. This project involves technical upgrades to a synthetic water treatment unit in order to produce solvent oil. The project construction includes: a production facility for the deep processing of stable light hydrocarbons, workshop control rooms, power distribution rooms, heat transfer oil furnace rooms, storage areas for raw materials and products, as well as loading and unloading facilities. Some of the equipment is based on the existing facilities and frameworks from the current synthetic water project, while utility systems such as circulating water, fresh water, air compression, nitrogen production, steam, and those for office and living purposes rely on the existing systems from the Yitai coal-to-oil project.
