Abstract

A system for generating electricity containing a power generating device and, operatively connected thereto, a fluid lubricated rotary positive displacement system. The rotary positive displacement system has a feed means for supplying gas at a pressure of from about 0.2 p.s.i.g. to about 400 p.s.i.g. to a rotary positive displacement compressor. The rotary positive displacement compressor has a discharge pressure of from about 20 to about 950 p.s.i.g., a pressure ratio per stage of from about 1.1 to about 6.0, and a flow capacity of from about 5 to about 3,000 standard cubic feet per minute. The system also contains a receiving tank connected to the rotary positive displacement compressor, a device for feeding liquid to the receiving tank, a device for cooling a mixture of gas and liquid, a device for separating a mixture of gas and liquid, and a device for feeding liquid to the rotary positive displacement compressor.

Dependent claims

A system for generating electricity comprising a power generating device and, operatively connected thereto, a fluid lubricated rotary positive displacement compressor system, wherein:

(a) said fluid lubricated rotary positive displacement system is comprised of a rotary positive displacement compressor, wherein said rotary positive displacement compressor has a discharge pressure of from about 20 to about 950 pounds per square inch gauge, a pressure ratio per stage of from about 1.1 to about 30, and a flow capacity of from about 5 to about 3,000 standard cubic feet per minute;
and
(b) said fluid lubricated rotary positive displacement system is comprised of a receiving tank connected to said rotary positive displacement compressor, means for feeding gas at a pressure of from about 0.2 to about 400 pounds per square inch gauge to said rotary positive displacement compressor, means for feeding liquid to said receiving tank, means for cooling a mixture of said gas and said liquid, means for separating said mixture of said gas and said liquid, and means for feeding said liquid to said rotary positive displacement compressor.

Dependencies are inferred from the claim text.
