Lifting of the Gasification Furnace at Yanzhou Coal Industry Yulin Energy Chemicals – Author/Source: Date: May 31, 2020; Clicks: 46. On May 31, 2020, the second-phase project of Yanzhou Coal Industry Yulin Energy Chemicals reached a key milestone in the industrialization of radiation-waste boiler gasification technology, with the lifting of the key equipment, namely the gasification furnace and its water-cooling wall components, taking place at that time. The Yanzhou Coal Industry Yulin Energy Chemical Co., Ltd. project for the production of 500,000 tons per year of polymethoxymethane (with an initial capacity of 100,000 tons per year). The total planned investment for the project is 4.596 billion yuan. The project involves the production of polydimethyl methoxide from coal through methanol synthesis, and the main technologies used include coal gasification, raw gas purification, methanol synthesis, methanol distillation, sulfur recovery, and DMMn preparation. The project uses one set of oxygen generation equipment with a capacity of 92,000 Nm3/h ； Gasification is carried out using the multi-nozzle (opposed-type) water-coal slurry gasification technology owned by Yankuang Group Company, with a total effective gas production capacity of 240,800 Nm3/h. Three gasifiers with a capacity of 2,000 t/d each are installed (2 quenching type and 1 semi-waste-heat boiler), operating in a 2-on-1-backup configuration; the quenching type gasifiers were successfully put into operation in October 2019 ； The purification unit employs the Dalian University of Technology low-temperature methanol washing process ； Methanol synthesis utilizes technology from East China University of Science and Technology ； Distillation employs the Tianjin Beiyang five-column methanol distillation technology, with a processing capacity of 5,000 tons per day in total. The DMMn plant utilizes Metada’s DMMn technology, and its construction is carried out in two stages: first, a plant with an annual production capacity of 100,000 tons is built, followed by the construction of a plant with a capacity of 400,000 tons.
On May 30, 2020, the radiation waste boiler gasifier and water wall internals for the second phase of Yanzhou Coal Industry’s Yulin Energy Chemical project were lifted into place. The radiation waste boiler gasifier of the second phase of Yankuang Yulin Energy Chemical Project is an industrial demonstration unit for the multi-nozzle opposed water-coal slurry gasification waste boiler–quenching process. According to China Tianchen Design Institute, the parameters of the unit are as follows: coal feeding rate of 1,619 tons per day (on a dry basis); effective gas production volume of 120,400 m3/h. The inner diameter of the gasifier shell is φ3.6/4.2 meters, and the total height of the gasifier is 45.75 meters. The gasification chamber is constructed using refractory bricks and is approximately 8 meters in height. The radiation waste heat exchanger section features a membrane-type water-cooling wall structure and is about 25 meters high, while the quenching section is approximately 6 meters high. The total weight of the gasifier is 746 tons. The Yulin Energy Chemical Project Phase II of Lanzhou Coal Industry utilizes three gasifiers with a capacity of 2,000 tons per day each, with two in operation and one as a backup. Vaporization pressure: 6.5 MPa. The total effective air volume is 240,800 m3/h. Two of these gasifiers with a quenching process were put into operation in October 2019.
