초록 ▼

A method for treating a landfill formation. The method includes the steps of preparing a water soluble resin solution, preparing a catalyst solution, and introducing separate streams of the resin and the catalyst into the landfill formation in a manner that avoids mixing air into the resin and catalyst streams and promotes mixing of the resin and catalyst streams to yield a substantially fluid impervious treatment substrate within desired locations in the landfill formations to inhibit effusion of gas and travel of liquids therein.

대표청구항 ▼

1. Apparatus for treating a landfill formation having cavities therein, the apparatus comprising a source of a pressurized stream of resin solution, a source of a pressurized stream of a catalyst solution, and a probe for separately conveying the stream of the resin solution and the stream of the catalyst solution within the probe toward a desired location in the landfill formation corresponding to the location of one or more of the cavities and thereafter ejecting the streams of resin and catalyst into the desired location in the landfill in a manner that promotes travel of the resin and catalyst into one or more of the cavities and promotes mixing of the catalyst and the resin streams to promote reaction thereof to yield a substantially fluid impervious treatment substrate within one or more of the cavities in the landfill formation to inhibit effusion of gas and travel of liquids therein, the probe having separate resin and catalyst inlets in flow communication with respective and separate resin and catalyst flow paths within the probe, and separate resin and catalyst outlets in flow communication with the resin and catalyst flow paths, respectively, and the formation for ejecting the resin and catalyst from the probe, wherein resin outlets are located adjacent catalyst outlets and positioned such that the ejected resin and catalyst contact one another and form a stream of resin and catalyst that promotes mixing of ejected resin with ejected catalyst within the formation. 2. The apparatus of claim 1, wherein the source of pressurized resin comprises a tank of a resin solution and a pump for pressurized conveyance of the resin solution to the probe. 3. The apparatus of claim 1, wherein the source of pressurized catalyst comprises a tank of a catalyst solution and a pump for pressurized conveyance of the catalyst solution to the probe. 4. The apparatus of claim 1, wherein the resin is an aminoplast resin. 5. The apparatus of claim 1, wherein the catalyst comprises a sulfonic acid. 6. The apparatus of claim 1, wherein the probe comprises a plurality of probes. 7. The apparatus of claim 1, wherein the probe comprises a head section having separate resin and catalyst inlets in flow communication with separate resin and catalyst flow paths, respectively, located within the head section; an extended body section having separate resin and catalyst flow paths in respective flow communication wit the resin and catalyst flow paths of the head section, and a cone section, having separate resin and catalyst flow paths in respective flow communication wit the resin and catalyst flow paths of the body section, the cone section further including a plurality of resin ejection conduits and a plurality of catalyst ejection conduits in respective flow communication with the resin and catalyst flow paths of the cone section, each resin and catalyst ejection conduit further being in flow communication with the formation and positioned such that resin and catalyst are ejected into the formation in a manner that promotes mixing of resin and catalyst within the formation.
