Abstract
Abstract An oil pollution totalizer for accumulating all of the oil from a sample stream at a rate that is directly proportional to the rate of oil being discharged from the stream. The totalizer essentially comprises means for controlling the sample flow rate in proportion to the stream flow rate, means for removing the oil from the sample stream, and means for storing the oil for subsequent analysis.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
A system for determining the rate and total amount of oil discharged in a flowing discharge stream comprising, means for removing a predetermined sample of said flowing discharge stream; contactor means for intimately mixing said sample with a predetermined volume of solvent; chamber means for receiving and processing the intimately mixed sample and solvent to form a separable first oil-solvent phase and a second phase which is relatively clean; means for recycling the first oil-solvent phase through said contactor means; and outlet means for discharging said relatively clean second phase from said chamber means to an outlet line; flow rate control means operably connected in said outline line; and means connected for sensing the relative flow rates of said relatively clean second phase and said flowing discharge stream and controlling said flow rate control means such that the flow rate of said relatively clean second phase is maintained in predetermined direct relation to the flowing discharge stream.
Claim 2
Independent Claim
157 words
A system for determining the rate and total amount of oil discharged in a flowing discharge stream comprising, means for removing a predetermined sample of said flowing discharge stream; contactor means for intimately mixing said sample with a predetermined volume of solvent; chamber means for receiving and processing the intimately mixed sample and solvent to form a separable first oil-solvent phase and a second phase which is relatively clean; means for recycling the first oil-solvent phase through said contactor means; and outlet means for discharging said relatively clean second phase from said chamber means to an outlet line; flow rate control means operably connected in said outline line; and means connected for sensing the relative flow rates of said relatively clean second phase and said flowing discharge stream and controlling said flow rate control means such that the flow rate of said relatively clean second phase is maintained in predetermined direct relation to the flowing discharge stream.
Claim 3
Dependent Claim
27 words
The system according to claim 1, wherein the controller means is connected for sensing the discharge stream downstream from the location at which said sample is taken.
Claim 4
Dependent Claim
28 words
A system according to claim 1, wherein the controller means is operably connected through sensors for sensing the flow rate of the discharge stream and said second phase.
Claim 5
Dependent Claim
33 words
A system according to claim 1, including filter means connected with said outlet means from said chamber means for removing particulate matter, entrained solvent and the like, from said second phase exiting therefrom.
Claim 6
Dependent Claim
24 words
A system according to claim 1, wherein said flow control means comprises a valve connected for controlling the discharge flow rate of second phase.
Claim 7
Independent Claim
109 words
A method of measuring the rate and total amount of oil contained in flowing discharge stream comprising the steps of: a. withdrawing a predetermined sample from said discharge stream; b. contacting said sample with a predetermined constant volume of solvent in a contactor to form a mixed stream; c. separating by gravity in a chamber said mixed stream into a first oil-solvent phase and a second phase relatively free of oil; d. recycling said first oil-solvent phase through said contactor; and e. discharging said second phase from said chamber through an outlet line at a rate which is directly proportional to the flow rate of said flowing discharge stream.
Claim 8
Independent Claim
109 words
A method of measuring the rate and total amount of oil contained in flowing discharge stream comprising the steps of: a. withdrawing a predetermined sample from said discharge stream; b. contacting said sample with a predetermined constant volume of solvent in a contactor to form a mixed stream; c. separating by gravity in a chamber said mixed stream into a first oil-solvent phase and a second phase relatively free of oil; d. recycling said first oil-solvent phase through said contactor; and e. discharging said second phase from said chamber through an outlet line at a rate which is directly proportional to the flow rate of said flowing discharge stream.
Claim 9
Dependent Claim
26 words
The method of claim 6, including the step of: f. filtering the second phase of said mixed stream subsequent to removal of the oil-solvent phase therefrom.
Claim 10
Dependent Claim
28 words
The method of claim 7, including the step of: g. regulating the rate of flow of said second phase of said mixed stream after filtering has been accomplished.
