Construction Status of Hubei Sanning Ethylene Glycol Project Author/Source: Refining & Chemical Industry Updates Date: 2020-04-06 Clicks: 52 On March 29, another landmark structure in the urea production area of the Hubei Sanning Ethylene Glycol Project – the high-altitude flare tower – began to be installed. It is understood that this high-altitude torch is an environmental protection device designed to handle the waste gases and toxic gases generated by various production units within the plant, as well as flammable gases in the event of accidents. This torch is designed with 5 torch nozzles sharing one tower, including a high-pressure torch, a low-pressure torch, a high-pressure ammonia torch, a slightly positive pressure ammonia torch, and an acidic gas torch. To ensure safe operation, the system features a jet-type molecular seal design, windproof and heat-insulating torch nozzles, three ignition methods, and fully automated control. The high-altitude torch steel tower covers an area of about 400 square meters, has 12 floors, and its total height is 100.5 meters. It is primarily used to support the flare tower, allowing the gas to be safely transported through it to high altitudes for combustion. The main body of the entire tower is made of Q345B low-alloy high-strength structural steel. The tower components, including the tower columns, crossbars, and rigid diaphragms, are connected using flanges, with reinforced connection bolts featuring double nuts to effectively prevent loosening. At present, the installation work for the torch apparatus has been fully underway. The Hubei Sanning Ammonia Synthesis Raw Material Structure Adjustment and 600,000 tons/year Ethylene Glycol Production Project (Phase I) is based on the 520,000 tons/year ammonia production capacity of Sanning Company’s urea plant and Tiantian Company’s plants. Without increasing this capacity, the existing urea production facilities that use bituminous coal as raw material and rely on atmospheric-pressure batch fixed-bed gasifiers, atmospheric-pressure desulfurization processes, and high-pressure ammonia synthesis, as well as the downstream urea and ammonium bicarbonate production units, are to be phased out. The total estimated investment for this project is 10 billion yuan; it involves the construction of a new facility that uses high-quality Shenhua coal as raw material to produce 400,000 tons per year of ethylene glycol and 520,000 tons per year of synthetic ammonia ； Using sulfur as raw material, 800,000 tons per year of industrial-grade sulfuric acid is produced.
