A vapor compression system comprising: a condenser; an expansion device; an evaporator; a compressor; and a lubrication reclamation system comprising: a still for receiving and containing a mixture of liquid refrigerant and lubricant and also refrigerant gas; and an ejector including an inlet portion, an outlet portion, and a vent portion, wherein the vent portion is located in a vent line in fluid communication with the still, wherein the inlet portion is connected to a discharge line of the compressor and is at an input pressure and receives relatively high pressure liquid or gas, the vent portion is at a relatively low pressure and the outlet portion is connected to a suction line of the compressor and is at a pressure that is intermediate to the input pressure and the vent pressure, characterised in that said vent portion is located at a point above the liquid level in the still, such that as the high pressure liquid or gas passes into the inlet and through the ejector the lower pressure of the vent portion results in refrigerant vapour from the still flowing through the vent line into the ejector and then out of the outlet portion. a condenser; an expansion device; an evaporator; a compressor; and a lubrication reclamation system comprising: a still for receiving and containing a mixture of liquid refrigerant and lubricant and also refrigerant gas; and an ejector including an inlet portion, an outlet portion, and a vent portion, wherein the vent portion is located in a vent line in fluid communication with the still, wherein the inlet portion is connected to a discharge line of the compressor and is at an input pressure and receives relatively high pressure liquid or gas, the vent portion is at a relatively low pressure and the outlet portion is connected to a suction line of the compressor and is at a pressure that is intermediate to the input pressure and the vent pressure, characterised in that said vent portion is located at a point above the liquid level in the still, such that as the high pressure liquid or gas passes into the inlet and through the ejector the lower pressure of the vent portion results in refrigerant vapour from the still flowing through the vent line into the ejector and then out of the outlet portion. a still for receiving and containing a mixture of liquid refrigerant and lubricant and also refrigerant gas; and an ejector including an inlet portion, an outlet portion, and a vent portion, wherein the vent portion is located in a vent line in fluid communication with the still, wherein the inlet portion is connected to a discharge line of the compressor and is at an input pressure and receives relatively high pressure liquid or gas, the vent portion is at a relatively low pressure and the outlet portion is connected to a suction line of the compressor and is at a pressure that is intermediate to the input pressure and the vent pressure, characterised in that said vent portion is located at a point above the liquid level in the still, such that as the high pressure liquid or gas passes into the inlet and through the ejector the lower pressure of the vent portion results in refrigerant vapour from the still flowing through the vent line into the ejector and then out of the outlet portion.
