    propylene refrigerant criteria



    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?

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

    Re: propylene refrigerant criteria

    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

    If you did your question would be answered.
