How to Choose the Right Chemical Tower Packing

Chemical tower packing is a kind of solid filler, because of its easy materials, convenient manufacturing, cheap, so it is widely used at present. Its function is to provide sufficient contact surface for gas and liquid, and to create conditions for strengthening its turbulence degree, so as to facilitate mass transfer. But the current chemical packing market is mixed, so we need to know our requirements before we buy chemical tower packing, but also to understand what kind of chemical packing can be used.

The efficiency of packed tower has a great relationship with the chemical packing used. Generally, the chemical packing has the following requirements:

1, chemical packing for the material processing requirements have good corrosion resistance;

2, the chemical filler is larger than the surface. That is, the surface area of packing layer per unit volume should be large;

3, the density of the chemical packing itself (including material and structure) should be small, and have enough mechanical strength;

4, chemical packing surface wettability is better, and in the structure should be conducive to close contact, promote turbulence;

5, chemical packing void rate (also known as free volume) to large. That is, the void volume of packing layer per unit volume should be large.
