Abstract
A lubricant still for use in a compressor for separating oil from refrigerant, includes a vessel having an inlet for incoming oil laden refrigerant, an outlet for gaseous refrigerant, and an outlet for refrigerant laden oil. A separating structure is provided for separating transitioning oil laden refrigerant from the incoming oil-laden refrigerant, wherein the oil laden refrigerant progressively changes to the refrigerant laden oil closer to the outlet for refrigerant laden oil. A heating device is used for heating the incoming oil laden refrigerant and transitioning oil laden refrigerant, for facilitating the formation of the gaseous refrigerant and the refrigerant laden oil.
