Abstract
Abstract A method for the removal of organic compounds from columns of air or water. The method utilizes a solidifying organic polymer-based filtration media and activated carbon placed in separate containers and arranged in an in-line, two phase process to extract organic compounds and metals from feed streams containing emulsified or suspended concentrations of organic contaminants by absorbing and solidifying the organics into an easily retrievable, disposable mass. The treated feed streams exit the process containing acceptable limits of the organic compounds and metals within the fluid columns to permit their free release into the environment.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
168 words
An apparatus for removing, containing, and collecting organic contaminants from a fluid column, comprising: a container having an inlet port for receiving a feed stream of organic contaminants carried within a fluid column and an outlet port for discharging, as a processed feed stream, fluid from the container for release into the environment; and a plurality of absorbent devices arranged in stratification within the container to establish chambers of distinct organic compound absorption units, each absorbent device comprising an outer envelope layer of textile material having a plurality of stacked layers of textile material disposed within the envelope layer and forming a plurality of chambers in stratification with a polymer material having the property of absorbing and solidifying liquid hydrocarbons being disposed in each of the chambers, and a seam joinder of the envelope layer and the stacked layers wherein said plurality of stacked textile material layers dispersively conduct liquid hydrocarbons under capillary attraction throughout the interior of said envelope layer for absorption and solidification by said polymer.
Claim 2
Independent Claim
168 words
An apparatus for removing, containing, and collecting organic contaminants from a fluid column, comprising: a container having an inlet port for receiving a feed stream of organic contaminants carried within a fluid column and an outlet port for discharging, as a processed feed stream, fluid from the container for release into the environment; and a plurality of absorbent devices arranged in stratification within the container to establish chambers of distinct organic compound absorption units, each absorbent device comprising an outer envelope layer of textile material having a plurality of stacked layers of textile material disposed within the envelope layer and forming a plurality of chambers in stratification with a polymer material having the property of absorbing and solidifying liquid hydrocarbons being disposed in each of the chambers, and a seam joinder of the envelope layer and the stacked layers wherein said plurality of stacked textile material layers dispersively conduct liquid hydrocarbons under capillary attraction throughout the interior of said envelope layer for absorption and solidification by said polymer.
Claim 3
Independent Claim
212 words
An apparatus for removing, containing, and collecting organic contaminants from a fluid column, comprising: a first container having an inlet port for receiving a feed stream of organic contaminants carried within a fluid column and an outlet port for discharging fluid from the first container; a plurality of absorbent devices arranged in stratification within the first container to establish chambers of distinct organic compound absorption units, each absorbent device comprising an outer envelope layer of textile material having a plurality of stacked layers of textile material disposed within the envelope layer and forming a plurality of chambers in stratification with a polymer material having the property of absorbing and solidifying liquid hydrocarbons being disposed in each of the chambers, and a seam joinder of the envelope layer and the stacked layers wherein said plurality of stacked textile material layers dispersively conduct liquid hydrocarbons under capillary attraction throughout the interior of said envelope layer for absorption and solidification by said polymer; a second container having an inlet port for receiving the fluid discharged from the first container and an outlet port for discharging, as a processed feed stream, fluid from the second container for release into the environment; and an amount of activated carbon material in a stratified arrangement within the second container.
