The installation of the pipeline attached to Tower T6 at the Ethylene Glycol Facility of Yueneng Group’s Chemical Materials Company was completed. Author/Source: Yueneng News. Date: June 29, 2022. Views: 12. On June 27, the largest-diameter special-shaped pipeline attached to a tower at the Ethylene Glycol Facility – the pipeline attached to Tower T6 – was successfully installed, providing valuable experience for the installation of other such pipelines in the future. The special-shaped accessory pipeline for the T6 tower installed this time has a diameter of 2.4 meters, with a total vertical installation length of 48 meters. This pipeline is of eccentric special shape; the weight of the pipeline including insulation is 70 tons, and its installation height is 94 meters. The amount of welding required is 1,440 inches of weld length. The startup project for the first phase of Shaanxi Yulin Energy Group Co., Ltd.’s coal-to-ethylene glycol facility—which aims to produce 400,000 tons of ethylene glycol per year out of a total planned capacity of 1.2 million tons per year—is the initial project undertaken by Yulin Energy Group at the Coal-based Clean Fuel Base and High-end Chemical Materials Base in Qingshui Industrial Park, Yushen Industrial Zone. The project is planned to cover a total area of 711 mu, with an estimated investment of 6 billion yuan. The construction period is set at 30 months, and it is scheduled to be completed and put into operation in 2022. The project 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: 3×350 t/h high-temperature and high-pressure circulating fluidized bed boilers + 2×30 MW extraction-backpressure steam turbine generator sets, an air separation unit, a circulating water station, a demineralized water plant, storage and transportation facilities, a sewage treatment plant, etc. The gasification unit employs the Collin powder gasification technology and includes 2 powder gasifiers; the ethylene glycol unit uses the Zhongke Yuandong ethylene glycol technology. Carbon monoxide and hydrogen are used to indirectly synthesize ethylene glycol through carbonylation, coupling, and hydrogenation, with by-products including dimethyl carbonate, crude ethanol, mixed alcohols, sulfur, liquid oxygen, and liquid nitrogen.
