Driven by the rapid development of the upstream and downstream industrial chains, the tower packing industry has good development prospects.
Packed tower refers to a tower equipment with gas absorption, distillation, extraction and other purposes. It is one of the gas and liquid mass transfer equipment commonly used in chemical enterprises. Its working principle is that packing is used as the basic component, and the liquid forms a film on the surface of the packing. The gas flows in a continuous phase and achieves the purpose of gas absorption, distillation and extraction through mass transfer and heat transfer between the gas and liquid phases. The filling in the tower is called tower packing, and its main function is to provide a sufficient contact surface for the gas and liquid phases.
Currently, the common tower packings on the market are divided into two categories, namely structured packings including wire mesh corrugated packing, plate corrugated packing, Grich grid packing, mesh grid packing, Goodlow packing, pulse packing, etc. Packing and bulk packing including flat rings, saddle rings, Nutter rings, stepped rings, Raschig rings, Pall rings, conjugate rings, etc. Tower packing is an important part of the packed tower, and its material quality plays a decisive role in the operation and performance of the packed tower.
Tower packing materials are mainly divided into three categories: ceramics, metals, and plastics. Among them, plastic packing is the mainstream product in the tower packing market. It has the advantages of good corrosion resistance, good temperature resistance, good impact resistance, light weight, good toughness, and high cost performance. The main materials include polyethylene (PE), polypropylene ( PP), polyvinyl chloride (PVC), reinforced polypropylene (RPP), polyvinylidene fluoride (PVDF), etc. Polypropylene is the most commonly used plastic tower packing. At present, my country is an important producer of polypropylene in the world. In 2021, the total domestic polypropylene production capacity will be approximately 38 million tons, accounting for approximately 38% of the global total production capacity. The sufficient supply of raw materials has laid a good foundation for the development of the domestic tower packing industry.
Tower packing is mainly used in the field of petrochemical industry. At present, petrochemical industry is an important pillar industry of the national economy. It has a large economic total and high output correlation, and occupies an important position in my country’s industrial economic system. According to data from the China Petroleum and Chemical Industry Federation, domestic petrochemical enterprises above designated size will achieve cumulative revenue of 14.45 trillion yuan in 2021, a year-on-year increase of 30%. Against the background of the rapid development of the domestic petrochemical industry, the market demand for tower packing continues to increase and its scale continues to expand.
According to the “Tower Filling Industry Market In-depth Research and Investment Prospects Forecast Analysis Report 2022-2027” released by the Industrial Research Center, in Favored by the rapid development of the upstream and downstream of the industrial chain, the number of tower packing companies in my country continues to increase. Currently, local companies mainly include Wu Engineering, Cody Environmental Petrochemical, Zehua Chemical Engineering, Sulzer Engineering Machinery, Chuangju Technology, etc.
Industry Analysts personnel said that Wu Engineering is currently the leading company in the domestic tower packing market, with its corporate revenue reaching 92.8649 million in 2021 yuan, a year-on-year increase of 36%. In the future, as local leading companies continue to play a leading role and the petrochemical industry develops rapidly, the technology of domestic tower packing companies will continue to improve, market demand will continue to increase, and the industry development prospects are good. In the future, the domestic tower packing industry will need to continue to develop and apply simpler and more efficient packing, thereby promoting the accelerated development of the industry.
