Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
138 words
A METHOD OF CONTROLLING THE AMOUNT OF A REAGENT THAT IS CONTINUOUSLY MIXED WITH A STREAM OF OIL TO PRODUCE A STREAM OF AN OIL-CONTINUOUS MULTIPLE-PHASE LIQUID, WHICH METHOD INCLUDES THE STEPS OF: CONTINUOUSLY SAMPLING SAID STREAM OF MULTIPLE-PHASE LIQUID BY WITHDRAWING A SMALL MULTIPLE-PHASE SAMPLE STREAM THEREFROM; CONVERTING SAID SAMPLE STREAM INTO A SINGLE-PHASE STREAM BY MIXING THEREWITH A COMMON SOLVENT SOLUBLE WITH THE PHASES OF SAID MULTIPLE-PHASE SAMPLE STREAM, SAID SINGLE-PHASES STREAM CONTAINING A SMALL AMOUNT OF WATER AND HAVING A RESISTIVITY NO GREATER THAN 106 OHM CMS.; ELECTROMETRICALLY TESTING SAID SINGLE-PHASE STREAM TO ESTABLISH AN ELECTRICAL POTENTIAL VARYING WITH THE HYDROGEN ION CONCENTRATION OF SAID SINGLEPHASE STREAM; AND EMPLOYING SAID ELECTRICAL POTENTIAL TO CONTROL THE AMOUNT OF SAID REAGENT CONTINUOUSLY MIXED WITH SAID STREAM OF OIL IN A MANNER TO MAINTAIN SAID POTENTIAL SUBSTANTIALLY CONSTANT.
Claim 2
Dependent Claim
226 words
IN AN APPARATUS FOR CONTROLLING THE AMOUNT OF A REAGENT CONTINUOUSLY DELIVERED AS A STREAM TO A STREAM OF OIL AND MIXED THEREWITH TO FORM AN OIL-CONTINUOUSLY MULTI-PHASE MATERIAL FLOWING AS A MAJOR STREAM, THE COMBINATION OF: A SAMPLING MEANS FOR WITHDRAWING FROM SAID MAJOR STREAM A SMALL SAMPLE STREAM; A SOURCE OF A DILUENT COMPLETELY MISCIBLE WITH SAID OILCONTINUOUS MATERIAL; MEANS FOR MIXING WITH SAID SMALL SAMPLE STREAM A STREAM OF SAID DILUENT FROM SAID DILUENT SOURCE TO FORM A STREAM OF DILUTED SINGLE-PHASE LIQUID; MEANS FOR DEVELOPING AN ELECTRICAL POTENTIAL VARYING WITH THE HYDROGEN ION CONCENTRATION OF SAID DILUTED SINGLE-PHASE LIQUID, SAID MEANS INCLUDING A GLASS ELECTRODE, A REFERENCE ELECTRODE AND A SMALL BODY OF SAID DILUTED SINGLE-PHASE LIQUID IN CONTACT WITH SAID GLASS ELECTRODE AND IN IONIC COMMUNICATION WITH SAID REFERENCE ELECTRODE; MEANS FOR DELIVERING SAID STREAM OF DILUTED SINGLE-PHASE LIQUID TO SAID BODY TO CONTINUOUSLY RENEW SAME; CONTROL MEANS FOR VARYING THE AMOUNT OF SAID REAGENT CONTINUOUSLY DELIVERED TO AND MIXED WITH SAID STREAM OF OIL; AND MEANS FOR OPERATING SAID CONTROL MEANS IN RESPONSE TO CHANGE IN SAID ELECTRICAL POTENTIAL AND IN A MANNER TO INCREASE AND DECREASE IN SAID AMOUNT OF REAGENT DELIVERED TO SAID STREAM OF OIL UPON RESPECTIVE DECREASE AND INCREASE IN SAID ELECTRICAL POTENTIAL TO MAINTAIN THE HYDROGEN ION CONCENTRATION OF SAID DILUTED SINGLE-PHASE LIQUID SUBSTANTIALLY CONSTANT.
