View Full Version : Flammable hydrocarbons properties

I would like to know if when mixing hydrocarbon refrigerant with some oil lubricant the result mixture is more inflamable than hydrocarbon refrigerant?
Thank you

I suppose it depends on the type of oil however, the hydrocarbon element is combustible enough on its own when mixed with air in the correct ratio.

Is there a reason for you wanted to change its ignition point?

Thank you for your answer.. I would like to know if the oil lubricant can change the ignition point of hydricarbon refrigerant. If the resulting mixiture (oil + hydrocarbon) increases or decreses the flammability risk... sorry my english is not good..
Thank you..

Hi, :)

maybe I am not right... but if we are speaking about closed system without oxygen it is not possible to have fire.... maybe carbonization of oil due to high discharge temperature....

Best regards, Josip :)

The ignition is not a problem unless you have an oxidizing agent such as oxygen. In a pure HC and oil environment, you do not have a problem.

But mixing and oil vapor or atomized into an HC stream with oxygen, it will change the ignition point.
