Fluid handling systems including a compressor

A reciprocating compressor comprising:

• a first portion comprising a motor housing configured to house a motor and a crankcase configured to house a crankshaft, wherein the motor housing is configured to receive a first fluid, wherein the crankcase is fluidly coupled to the motor housing, and wherein the crankcase is configured to receive the first fluid from the motor housing and output the first fluid;
• and
• a second portion fluidly isolated from the first portion, wherein the second portion forms a compressor inlet and a compressor outlet, and wherein the reciprocating compressor is configured to:
• receive a second fluid at a first pressure into the second portion via the
• compressor inlet;
• increase pressure of the second fluid from the first pressure to a second
• pressure;
• and
• provide the second fluid at the second pressure via the compressor outlet.

A method comprising:

• receiving a first fluid at a first pressure at a first inlet of a first portion of a compressor;
• increasing pressure of the first fluid from the first pressure to a second pressure via the compressor;
• outputting the first fluid at the second pressure via a first outlet of the first portion of the compressor;
• receiving a second fluid at a second inlet of a second portion of the compressor, wherein the first portion is configured to be fluidly isolated from the first portion;
• and
• outputting the second fluid via a second outlet of the second portion of the compressor.
