A method and system for providing substantially water-free compressed exhaust gas including extracting exhaust gas from a hydrocarbon fuel consuming engine, passing engine exhaust gas through a catalytic converter, passing the exhaust gas from the catalytic converter through a first compressor and chiller/separator in which the exhaust gas is compressed and chilled below the dew point temperature thereof to cause entrained water vapor therein to condense out, separating out and disposing of the condensed water to achieve extra dry exhaust gas and compressing the extra dry exhaust gas in a second compressor to provide compressed exhaust gas for industrial purposes such as for injecting into a subterranean formation to augment the production of crude oil.

1. A method providing substantially water-free compressed, extra dry exhaust gas for industrial purposes, comprising:(1) extracting exhaust gas from a hydrocarbon fuel consuming engine; (2) passing said exhaust gas through a catalytic converter; (3) passing exhaust gas from said catalytic converter

1. A method providing substantially water-free compressed, extra dry exhaust gas for industrial purposes, comprising:(1) extracting exhaust gas from a hydrocarbon fuel consuming engine; (2) passing said exhaust gas through a catalytic converter; (3) passing exhaust gas from said catalytic converter through a first compression step and cooling step in which the exhaust gas is chilled below the dew point temperature thereof to cause entrained water therein to condense out; (4) separating out and disposing of condensed water from step (3) to provide extra dry exhaust gas; and (5) compressing in a second compression step said extra dry exhaust gas to provide compressed extra dry exhaust gas for industrial purposes. 2. A method according to claim 1 including the step of passing said compressed extra dry exhaust gas for injection into a well.3. A system for providing extra dry, substantially water-free compressed exhaust gas comprising:a hydrocarbon fuel consuming engine that produces exhaust gas; a catalytic converter connected to receive exhaust gas from said engine and having a gas outlet; and a first compressor followed by a cooler by which gas from said catalytic converter is chilled to below the dew point temperature thereof to cause water entrained therein to condense out to extract substantially all water therefrom, the extracted water being disposed of to provide substantially water-free exhaust gas that is compressed in a second compressor, the compressed extra dry exhaust gas being usable for industrial purposes. 4. A system according to claim 3 including:an output conduit for conducting said compressed substantially water-free exhaust gas for injection into a well.
