Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
116 words
A process for separating gasoline from water in a water well wherein an interface separates the gasoline from the water, comprising the steps of: disposing a containment vessel in a water well below an interface of gasoline and water; placing a floating wick vertically through the interface, said wick being hydrophobic, and absorbing said gasoline with said wick; connecting said wick in open communication with the water well above the containment vessel; permitting the absorbed gasoline to flow by gravity from said wick to said containment vessel for collection therein; removing the collected gasoline from said containment vessel; and venting said containment vessel to the atmosphere to displace gases in said containment vessel to the atmosphere.
Claim 2
Dependent Claim
116 words
A process for separating gasoline from water in a water well wherein an interface separates the gasoline from the water, comprising the steps of: disposing a containment vessel in a water well below an interface of gasoline and water; placing a floating wick vertically through the interface, said wick being hydrophobic, and absorbing said gasoline with said wick; connecting said wick in open communication with the water well above the containment vessel; permitting the absorbed gasoline to flow by gravity from said wick to said containment vessel for collection therein; removing the collected gasoline from said containment vessel; and venting said containment vessel to the atmosphere to displace gases in said containment vessel to the atmosphere.
Claim 3
Dependent Claim
127 words
Apparatus for separating gasoline from water in a water well wherein an interface defines separation of the gasoline from the water comprising: a containment vessel constructed and arranged in combination with a water well for the storage of collected gasoline and having a lower portion comprising a gasoline storage area and an upper portion comprising a chimney vented to the atmosphere and permitting removal of collected gasoline; a wick of hydrophobic material capable of absorbing gasoline operatively connected to flotation means for enabling said wick to be disposed in the water well above the containment vessel and extending vertically through the interface; and a conduit extablshing communication between said wick and said containment vessel permitting a gravity flow of gasoline from said wick to said containment vessel.
Claim 4
Dependent Claim
127 words
Apparatus for separating gasoline from water in a water well wherein an interface defines separation of the gasoline from the water comprising: a containment vessel constructed and arranged in combination with a water well for the storage of collected gasoline and having a lower portion comprising a gasoline storage area and an upper portion comprising a chimney vented to the atmosphere and permitting removal of collected gasoline; a wick of hydrophobic material capable of absorbing gasoline operatively connected to flotation means for enabling said wick to be disposed in the water well above the containment vessel and extending vertically through the interface; and a conduit extablshing communication between said wick and said containment vessel permitting a gravity flow of gasoline from said wick to said containment vessel.
Claim 5
Dependent Claim
31 words
The apparatus according to claim 2 wherein said wick comprises a tubular element having a plurability of pores and a polyolefin sheet disposed about the outer periphery of said tubular element.
Claim 6
Dependent Claim
34 words
The apparatus according to claim 2 wherein said wick includes a tubular element, a first fibrous web roll fitted inside said tubular element, and a second fibrous web roll fitted outside said tubular element.
Claim 7
Dependent Claim
20 words
The apparatus according to claim 2 wherein the conduit is flexible and spiraled in a relaxed condition about the chimney.
Claim 8
Dependent Claim
35 words
The apparatus according to claim 5 wherein said flotation means comprises a flotation collar fixed to a top portion of the wick to maintain the wick in floating contact with the gasoline to be collected.
