:confused:If we use propylene as refrigerant in the screw compressor,is there any criteria of the propylene refrigerant?If some chemical plant can provide propylene which purity is up to 95%,can I use the propylene as refrigerant?

It is flammable

so be very carefull on how you use it.

Propylene is used as refrigerant. I want to know the purity level and its effects. :confused:

It should be 100% pure.....

If major impurity in propylene blend are propane (R290), 5% propane in propylene blend make small amount of glide - around 0.033 degree C ( 1MPa pressure and 19.48 degree C) and have none effect in practical use.

if dominate impurity are Ethane - it make more glide, much more than propane. In 1 MPa pressure, 5% ethane in propylene, dew-point 17.03 degree C and bubble point 13.23 degree C.

if you have choice, and don't can get pure >= 99.5% propylene, select propylene with propane as impurity before alternative propylene with methane as impurity

some welder fuel/MAP-gas have 99.5 % Propylene inside and 0.5% impurity in this blend are propane in most case

Did you look at the link I posted?
If you did your question would be answered.
