What is claimed is: 1. A pollution control system comprising: a compressor; a first flow line connected between a well and the compressor for supplying natural gas from the well to the compressor; a combustion engine connected to the compressor for driving same; a second flow line connected between the first flow line and the engine for supplying a portion of the natural gas to the engine to power the engine; a third flow line connecting the engine to the first flow line downstream of the connection of the second flow line to the first flow line so that the exhaust from the engine mixes with the natural gas in the first flow line before the mixture enters the compressor for compression; a separator connected to the compressor for receiving the compressed mixture from the compressor and separating the exhaust from the natural gas; and means for passing the separated natural gas to a destination. 2. The system of claim 1 wherein the third flow line is connected to the first flow line upstream of the connection of the first flow line to the compressor. 3. The system of claim 1 wherein the exhaust includes unspent hydrocarbons. 4. The system of claim 1 wherein the exhaust includes at least one of water, carbon dioxide, and nitrogen. 5. The system of claim 1 wherein the separating means separates the exhaust from the natural gas by resin re-absorption. 6. A pollution control method comprising: connecting a first flow line between a gas well and a compressor for supplying natural gas from the well to the compressor; connecting a second flow line from the first flow line to a combustion engine for supplying a portion of the natural gas to the engine to power the engine; driving the compressor by the engine; passing the products of combustion and the unspent fuel from the engine to the first flow line downstream of the connection of the second flow line to the first flow line so that the exhaust from the engine mixes with the natural gas in the first flow line before the mixture enters the compressor; compressing the mixture in the compressor; passing the compressed mixture to a separator; separating the exhaust from the natural gas in the separator; and passing the separated natural gas to a destination. 7. The method of claim 6 wherein the products of combustion and the spent fuel from the engine are passed to the first flow line upstream of the connection of the first flow line to the compressor. 8. The method of claim 6 wherein the exhaust includes unspent hydrocarbons. 9. The method of claim 6 wherein the step of separating is by resin re-absorption. 10. The method of claim 6 wherein the exhaust includes at least one of water, carbon dioxide, and nitrogen. 11. The method of claim 10 further comprising reusing the separated water, carbon dioxide, and nitrogen.
