The Mechanical, Electrical and Instrumentation Center of Yueneng Chemical organized a special review meeting for the drawings related to the desulfurization and denitrification projects intended to be installed in the thermal power stations. Author/Source: Yueneng Chemical Date: 2022-07-03 Clicks: 14 To ensure the smooth progress of the construction of these desulfurization and denitrification projects, to save on construction costs, and to improve the quality of the construction, on July 1st, the Mechanical, Electrical and Instrumentation Center of Yueneng Chemical arranged for relevant personnel from Nanjing Longyuan to conduct a special review of the drawings for these projects. During the meeting, the responsible persons from the Mechanical, Electrical and Instrumentation Center and the Nanjing Longyuan project reviewed in detail aspects such as the quantity of thermal power instruments to be supplied, brand requirements, installation requirements, installation methods, and the supply plan for spare parts. Taking into account the construction schedule, they carefully examined the drawings related to desulfurization and denitrification in the thermal power station, and compiled a list of the existing issues. This meeting further improved the accuracy of the procurement plans for instruments related to desulfurization and denitration systems, providing strong guidance for the high-quality construction of the company’s ethylene glycol project. The first phase of the project to produce 400,000 tons per year of ethylene glycol as part of Shaanxi Yulin Energy Group Co., Ltd.’s 1.2 million tons per year coal-based ethylene glycol production capacity, is a project that marks the start of operations at the coal-based clean fuel 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 711 mu, with an estimated investment of 6 billion yuan; the construction period is set at 30 months, and completion and operation are scheduled for 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: 3×350t/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, and sewage treatment plants. 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.
