Patent ID: 7832992

Claim:
A gas compression system, comprising: a multi-stage compressor assembly, comprising: a first stage centrifugal compressor comprising a first gas inlet and a first gas outlet; a second stage centrifugal compressor comprising a second gas inlet and a second gas outlet; and a third stage centrifugal compressor comprising a third gas inlet and a third gas outlet; and an air cooling assembly disposed vertically above the multi-stage compressor assembly, wherein the air cooling assembly comprises: a first air-cooled heat exchanger coupled to the first gas outlet of the first stage centrifugal compressor and coupled to the second gas inlet of the second stage centrifugal compressor; a second air-cooled heat exchanger coupled to the second gas outlet of the second stage centrifugal compressor and coupled to the third gas inlet of the third stage centrifugal compressor; a third air-cooled heat exchanger coupled to the third gas outlet of the third stage centrifugal compressor, wherein the first, second, and third air-cooled heat exchangers are arranged adjacent to one another in a common horizontal plane; and a single fan configured to move cooling air in parallel through the first, second, and third air-cooled heat exchangers in a direction generally perpendicular to the common horizontal plane; and a disabled liquid cooling system comprising: a first disabled liquid cooler disposed along a first gas flow path between the first gas outlet of the first stage centrifugal compressor and the second gas inlet of the second stage centrifugal compressor, wherein the first gas flow path extends through the first air-cooled heat exchanger; a second disabled liquid cooler disposed along a second gas flow path between the second gas outlet of the second stage centrifugal compressor and the third gas inlet of the third stage centrifugal compressor, wherein the second gas flow path extends through the second air-cooled heat exchanger; a third disabled liquid cooler disposed along a third gas flow path extending downstream from the third gas outlet of the third stage centrifugal compressor, wherein the third gas flow path extends through the third air-cooled heat exchanger; wherein the first, second, and third disabled liquid coolers each have structural modifications to flow only compressed gas without any liquid coolant circulation, wherein the structural modifications include removal of liquid coolant tube cores and disconnection of liquid coolant connections to define a hollow cooler chamber.
