Patent ID: 8623119

Claim:
In a process wherein a compressor is used to compress a first gas stream containing a compressor lubricant contaminant at a first pressure to produce a second gas stream at a second, higher pressure, said second gas stream comprising said contaminant and said compressor lubricant, said second gas stream being separated in a first separation zone into a third, substantially lubricant-free compressed gas stream and a reclaimed lubricant stream, the improvement comprising: the compressor being used to compress a first hydrocarbon stream containing a compressor lubricant contaminant comprising a second hydrocarbon having a higher boiling point than said first hydrocarbon; and introducing said reclaimed lubricant stream leaving said first separation zone into a second separation zone comprising a liquid-liquid separation to remove said second hydrocarbon and produce a substantially second-hydrocarbon-free, reclaimed lubricant stream.
