Abstract:
A system for compressing gas comprised of a liquid lubricated positive displacement compressor system, wherein:(a) said liquid lubricated rotary displacement system is comprised of a rotary positive displacement compressor comprising a housing comprising a curved inner surface with a profile equidistant from a trochoidal curve, an eccentric mounted on a shaft disposed within said housing, a first rotor mounted on said eccentric shaft which is comprised of a first side, a second side, and a third side, a first partial bore disposed at the intersection of said first side and said second side, a second partial bore disposed at the intersection of said second side and said third side, a third partial bore disposed at the intersection of said third side and said first side, a first roller disposed and rotatably mounted within said first partial bore, a second roller disposed and rotatably mounted within said second partial bore, and a third roller disposed and rotatably mounted within said third partial bore, (b) said liquid lubricated rotary positive displacement system is comprised of means for separating a mixture of gas and liquid to produce a separated liquid, wherein said means for separating said mixture of gas and liquid is connected to said rotary positive displacement compressor; (c) said liquid lubricated rotary positive displacement system is comprised of a dehydrator disposed outside of said rotary positive displacement compressor for dehydrating said separated liquid and for producing a dehydrated separated liquid; and (d) said liquid lubricated rotary positive displacement system is comprised of a means for cooling said dehydrated separated liquid and producing a cooled dehydrated separated liquid; and (f) said liquid lubricated rotary positive displacement system is comprised of means for feeding said cooled dehydrated separated liquid into said rotary positive displacement compressor.
