Abstract
Method and apparatus for treating contaminants on a site, especially a deep well site includes delivering a first stream of a first gas to a first port of a laminar microporous diffuser and delivering a second stream of a second gas to a second port of the laminar microporous diffuser to effect mixing of the first and second streams of gases within the laminar microporous diffuser.
Claims24
Apparatus comprises:
- a well;
- a first compressor to deliver a first stream of gas;
- a second compressor to deliver a second stream of gas;
- a microporous diffuser disposed in the well, the microporous diffuser having a top cap with first and second inlet ports coupled to the first and second compressors, the microporous diffuser, comprising:
- a first elongated member forming a sidewall having a plurality of microscopic openings, the sidewall defining an interior hollow portion of the first member with the interior hollow portion coupled to the first inlet port;
- a second elongated member forming a second sidewall having a plurality of microscopic openings, said second member defining a second interior portion and being disposed through the hollow portion of said first member, with the second interior portion being coupled to the second inlet port;
- and
- an end cap to seal a second end of the microporous diffuser with the first compressor delivering the first gas stream to peripheral portions of the microporous diffuser and the second compressor delivering the second stream of gas to central portions of the microporous diffuser, with the second stream of gas migrating to peripheral portions of the microporous diffuser to effect mixing of the first and second streams of gases within the microporous diffuser.

Apparatus for use with a well comprises:
- a ozone generator;
- a first compressor coupled to the ozone generator;
- a second compressor to deliver a second stream of gas;
- a microporous diffuser coupled to the first and second compressors, the microporous diffuser configured to cause the ozone generator to operate under a siphon condition, resulting at least in part by the flow of the second stream of gas through the microporous diffuser and to effect mixing of the first and second streams of gases within the microporous diffuser.
