The unshifted gas scrubber tower, part of the purification unit at Yueneng Chemical’s syngas center, was successfully hoisted into place. Author/Source: Yueneng Chemical. Date: April 28, 2022. Clicks: 17. At 16:26 on April 26, the core equipment of the purification unit, namely the unshifted gas scrubber tower, was successfully installed in place. The untransformed gas scrubber is the core equipment of the low-temperature methanol washing unit in the syngas purification system. It has a height of 57.06 meters, a diameter of 2.1 meters, and a net weight of 135.31 tons. Its primary function is to remove impurity gases such as H2S and CO2 from the untransformed gas coming from the heat recovery unit. 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 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, as well as 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.
