Should a packed tower or a plate tower be used in the deacidification process?
Thread Content
Hello everyone! I would like to ask: In typical natural gas processing plants, what type of towers are generally used in the acid removal process? Packed tower or plate tower? What type of packing or trays is used in each case? Thank you~~
Packed towers generally use bulk packing. For lower temperatures, plastic Bower rings can be used (it’s best to consult a design institute to determine the most suitable type of ring); for higher temperatures, stainless steel (free of CL-) or ceramic materials can be used
2# whsp8422: Does the person upstairs mean that packed towers are generally used? Please specify, thank you~
Stainless steel is not resistant to corrosion in environments with low concentrations of strong acids at high temperatures, whereas ceramics are different, unless it is an acid such as hydrofluoric acid that can corrode ceramics.
Some people don’t know that they don’t know. What are the levels of hydrogen sulfide and carbon dioxide? To what level of removal? At present, for pipeline transportation, plate towers are more commonly used; fillers are also employed, but they tend to get clogged more easily.
If you’re asking about what type of tower to use, turn to a process design institute – they can determine the appropriate type of tower based on your requirements. If a packed tower is to be used, ceramic material is suitable for the packing; ceramic packing offers excellent corrosion and heat resistance. It is also inexpensive and has good surface wetting properties. Its main disadvantages are that it is brittle and easy to break. It is widely used in processes such as gas absorption, gas washing, and liquid extraction
