Where are stainless steel towers mainly used
Information summary：Stainless steel tower belongs to pressure vessel mass transfer equipment, which is divided into distillation tower, absorption tower, desorption tower, extraction tower, washing tower, etc. It relies on gas-liquid/liquid-liquid mass and heat transfer to complete separation, absorption, purification, and gas purification; Select 304, 316L, duplex stainless steel, corrosion-resistant, hygienic and n
Stainless steel tower belongs to pressure vessel mass transfer equipment, which is divided into distillation tower, absorption tower, desorption tower, extraction tower, washing tower, etc. It relies on gas-liquid/liquid-liquid mass and heat transfer to complete separation, absorption, purification, and gas purification; Select 304, 316L, duplex stainless steel, corrosion-resistant, hygienic and non polluting materials, mostly used in working conditions with corrosive media and requirements for product purity.
1. Chemical and petrochemical industries
1. Distillation tower: Organic solvent distillation purification, solvent recovery, separation of mixed liquid materials;
2. Absorption/Analysis Tower: Process gas desulfurization, decarbonization, and recovery of chemical raw materials;
3. Used for the production of dyes, additives, chemical intermediates, and the treatment of weakly acidic and weakly alkaline corrosive materials.
2. Pharmaceutical industry
Distillation and purification of pharmaceutical intermediates, recovery of production solvents, and treatment of fermentation exhaust gases;
The 316L stainless steel tower meets GMP hygiene requirements, with easy to clean inner walls that do not contaminate pharmaceutical raw materials and prevent iron ion impurities from entering the product.
3. Food and beverage industry
Alcohol distillation, Baijiu purification, essence and spice, plant essential oil extraction;
Seasoning processing, material contact with stainless steel, hygienic and safe, with no risk of heavy metal precipitation.
4. Environmental waste gas treatment
Washing tower, absorption tower: processing VOCs waste gas, acid alkali waste gas, ammonia, hydrogen chloride and other harmful gases;
Smelting, factory production exhaust gas purification, spray neutralization and absorption of harmful components; Priority is given to 316L and 2205 duplex steel towers for corrosive exhaust gases.
5. New energy industry
Lithium battery solvent recovery and purification, wet electronic chemical refining and separation;
Production of biodiesel and bioethanol through distillation.
6. Other industrial scenarios
1. Metallurgy: Purification and recovery of smelting flue gas;
2. Pilot research and development: stainless steel distillation tower in university and enterprise laboratories, new process experiments;
3. 316L/duplex steel is selected for seawater and chloride ion conditions to resist chloride ion pitting corrosion.
