1: In the field of crude oil processing, one or three separators: the preliminary processing of gas-liquid separation, oil-water sedimentation and oil-water separation of the oil-gas-water mixture extracted from oil wells is the core part of the oilfield gathering and transportation project. The effect of oil-gas-water separation will directly affect the downstream processing of crude oil and natural gas and the discharge quality of produced water, which in turn affects product quality.
2: Natural gas domain --- alcohol ammonia desulfurization process: the raw gas enters from the bottom of the absorption tower, contacts with the lean amine liquid added at the top for desulfurization and purification, extracts from the top of the absorption tower, leaves the absorption tower rich amine liquid, and the heat exchanger and the The lean amine is excited in the excitation tower, and the removed hydrogen sulfide and carbon dioxide excited acid gas enters the Claus device for sulfur recovery, and the lean amine is pumped to the absorption tower and the collection tower through the cooling pump.
3: Crude oil refining field --- vacuum tower distillation process: the oil and gas at the top of the vacuum tower is continuously pumped away by the vacuum system for cooling, so that a negative pressure is formed in the tower, and the atmospheric residue is vaporized in large quantities, which needs to be decompressed. A wire mesh demister is installed on the top of the tower to prevent oil droplets from being pumped away.
4: Chemical production field---Sulfuric acid production process: sulfur or pyrite is burned or roasted in the air to obtain sulfur dioxide gas, using a solid catalyst to directly oxidize sulfur dioxide with oxygen in the air to obtain sulfur trioxide, trioxide Sulfur is combined with water in the absorption tower to obtain sulfuric acid. In the absorption tower, a wire mesh demister is used.
