Ethane, ethylene, propane, and propylene used in the chemical industry
Ammonia is used more frequently these days; although F22 is also used quite a lot, as people’s awareness of environmental protection grows, F22 is gradually being replaced.
Currently, 134A is gradually becoming popular.
The refrigerator itself uses F22, while ethylene glycol is used for the circulation
With the development of equipment, the lubricating oil for the chiller, an important operating device in ammonia synthesis plants, is now also cooled by ammonia. The refrigerant used in the liquid carbon dioxide production process is ammonia. One of the equipment in the water-cooled tower system of old air separation plants is the chiller, and its refrigerant seems to be F22. Additionally, methanol is also a good refrigerant.
Propylene refrigerant is used in the vinyl chloride plants based on the ethylene process
We are installing refrigeration in our new factory, using fluorine compounds for everything.
Let’s discuss what the difference is between using F22 and propylene
Our system is still using F22; the equipment is quite old.
The ammonia and Freon used by our company
5. Lithium bromide 10. Ethane
The ammonia and ethylene glycol used in our company: handshake
We use Freon units for cooling at -10 degrees, and ammonia for cooling at -5 degrees.
There are five types of refrigerants used in LNG plants: methane, ethylene, propane, isopentane, and nitrogen. This post was last edited by lsm224 on 2009-4-19 at 18:39.]
In enterprises that produce synthetic ammonia, if there are special requirements for refrigeration, ammonia cooling is generally used, with ice machines employed for this purpose. :handshake

Our company uses ethylene glycol, as well as lithium bromide for cooling
