The #2 boiler of Yulin Energy Chemical Materials’ 400,000 tons per year ethylene glycol production project powered on successfully. Author/Source: Huahua Network – Coal Chemical Industry. Date: May 6, 2023. Clicks: 69. At 22:54 on May 4th, the #2 boiler of this project owned by Shaanxi Yulin Energy Group’s Shaanxi Yulin Energy Chemical Materials Co., Ltd. was successfully brought online on the first attempt. The successful first ignition of Boiler No. 2 represents another important milestone following the successful ignition of Boiler No. 1 in this project. It indicates that the construction of this project is gradually moving into the trial production phase, providing a solid foundation for the successful completion of subsequent key stages such as project handover and commissioning trials. As the source of high-pressure steam power for the entire plant, the power center is responsible for maintaining a balance in the steam usage across the plant, while also providing essential steam for the purging and commissioning of the plant’s pipelines. The power center is equipped with 3 circulating fluidized bed boilers, each of which can produce 350 tons of high-pressure steam per hour ； Two 30-megawatt back-pressure steam turbine generators produce qualified medium and low-pressure steam through methods such as temperature and pressure reduction as well as driving the steam turbines, and possess power generation capabilities. Its accompanying environmental protection facilities for flue gas desulfurization and denitrification enable the flue gas emissions to be made \"cleaner\"” ； The coal supply system can provide fuel coal and raw coal for boilers and gasifiers. The first-phase project of Shaanxi Yulin Energy Group Co., Ltd., which involves the production of 1.2 million tons per year of ethylene glycol, with an initial capacity of 400,000 tons per year, is part of the initiatives undertaken by Yulin Energy Group in the Clean Fuel Production Base and High-End Chemical Materials Base located in the Qingshui Industrial Park of the Yushen Industrial Zone. The total planned area for this project is 1,711 mu, and the investment required is 6.243 billion yuan. The project uses mixed coal as raw material and employs Collin powder gasification to produce crude syngas. Ethylene glycol synthesis is a technology of Zhongke Yuandong. The construction includes a gasification unit, a purification unit, an H2/CO separation unit, an ethylene glycol unit, etc. The utility systems and supporting auxiliary facilities include: 3×350t/h high-temperature and high-pressure circulating fluidized bed boilers + 2×30MW back-pressure steam turbine generator sets, air separation units, circulating water stations, desalination stations, storage and transportation facilities, sewage treatment plants, etc.
