Application of Random Tower Packing

I) Petrochemical industry

In the process of oil refining, the distillation of crude oil is a key link. Random packing is widely used in crude oil fractionation towers. For example, in the process of separating crude oil into different fractions such as gasoline, kerosene, and diesel, random packing can make the gas phase of crude oil vaporized by heat and the reflux liquid phase fully contact on the packing surface. Due to the difference in boiling points of different fractions, during the gas-liquid contact process, each fraction is gradually separated at different heights in the tower according to its boiling point range, thereby improving the purity and quality of petroleum products and ensuring the quality of raw materials for subsequent petrochemical product production.

(II) Chemical product production

In the chemical synthesis industry, the production of many products is inseparable from processes such as distillation and absorption, and random packing also plays a big role. For example, in the production of basic chemical raw materials such as ethylene and propylene, random packing in the distillation tower helps to accurately separate impurities and target products in the reaction products. In the process of producing sulfuric acid, the random packing in the absorption tower can make sulfur dioxide gas fully contact with the absorption liquid, promote the absorption and conversion of sulfur dioxide, improve the production efficiency and purity of sulfuric acid, and ensure that the quality of chemical products meets industrial standards and market demand.

(III) Environmental Engineering Field

In terms of waste gas treatment, random packing plays an important role in the purification of harmful gases such as acid and alkali discharged from industry. For example, when treating waste gas containing sulfur dioxide, the random packing filled in the absorption tower makes the alkaline absorption liquid fully contact with the waste gas, and sulfur dioxide is absorbed by the absorption liquid, thereby reducing the concentration of pollutants in the waste gas, making it meet the emission standards and reducing pollution to the atmospheric environment. In sewage treatment, random packing can also be used in equipment such as aerated biological filter tanks. By providing a surface for microorganisms to attach and grow and a good gas-liquid contact environment, it promotes the degradation and removal of organic matter in sewage, improves the sewage treatment effect, and helps environmental protection.

(IV) Pharmaceutical Industry

In the pharmaceutical process, the purification and refining of drugs are crucial. Random packing is often used in the separation and distillation processes after drug extraction. For example, after extracting effective medicinal ingredients from natural plants, a distillation tower filled with random packing can be used to further purify the effective ingredients, remove impurities and solvent residues, improve the purity and quality stability of the drugs, ensure the safety and effectiveness of the drugs, and meet the strict quality standards of the pharmaceutical industry.
