Filed:

Appl. No.:

6/744376

Inventors:

Donald Faul - Sunset LA
Paul P. Broussard - Lafayette LA
Donald W. Granger - Lake Charles LA

Assignee:

Testrac, Inc. - Lake Charles LA

International Classification:

G01M 304

US Classification:

73 407

Abstract:

A method for determining the erosion of a borehole or cavity by providing a source of liquid inert gas, preferably nitrogen, placing the inert gas in a storage tank, and suspending the storage tank so that one may determine the actual weight of the nitrogen as it is withdrawn from the tank in liquid state. There is further provided hydraulic means for lifting or lowering the storage tank suspended from a weight cell as a tank is placed into use or non-use. Further, the liquid nitrogen is pumped from the storage tank with the use of a reciprocating pump, and converted into gaseous nitrogen (in the state of 100. degree. F. ) and is injected into a borehole or the like. The nitrogen gas is then allowed to flow under a certain pressure down the borehole, and due to the properties of nitrogen gas, the nitrogen interfaces at a horizontal plane as it moves down the borehole. Following completion of the nitrogen injection, nitrogen gas could be maintained within the borehole at a constant pressure and any upward movement of the interface over an extended and defined period of time, could determine location and the amount of leakage occurring within the borehole, casing seat or pipe.

Inventors:

Paul C. Broussard - Lafayette LA

International Classification:

B01D 1200

US Classification:

210634

Abstract:

A system for removing dissolved and undissolved oil from contaminated water which recycles and reclaims absorbing fluid. An absorbing fluid (CCl. sub. 2 FCClF. sub. 2) is used in a wet-spiral mixer-absorber-contactor to absorb oil contaminants in produced-water. A downflow spreader system in a processing separator separates the heavier oil absorbing fluid from the oil-decontaminated water. Unspent absorbing fluid is recycled to the absorber-contactor and the decontaminated water is released into the surrounding environment. Spent absorbing fluid is reclaimed in a distillation treatment unit where the oil is used as fuel oil or stored. The absorbing fluid's vapors are drawn off under vacuum from the distillation unit by a jet eductor pump, mixed and condensed with the decontaminated water which drives the jet pump, and then redirected into the system for reuse.

Paul C. Broussard - Lafayette LA

International Classification:

C02F 124
B01D 17035
B01D 17038

US Classification:

2102212

Abstract:

An apparatus and method for clarifying a contaminated fluid mixture containing contaminating fluid, principal liquid and solids. The apparatus comprises a vertically standing cylindrical vessel for separating the contaminants from the principal liquid; a preliminary separator for tangentially introducing the contaminated fluid into the vessel; sparging tubes to aerate the contaminated fluid mixture, thereby separating the contaminating fluid from the principal liquid and solids; and a reservoir for collecting the contaminating fluid. The reservoir and preliminary separator are located in the upper portion of the vessel. The sparging tubes are located in the lower portion of the vessel.
