A METHOD FOR CONTINUOUSLY DETERMINING THE CONCENTRATION OF A BORON TRIHALIDE IN A FLOWING STREAM OF LIQUID HYDROCARBON CONTAINING SAID BORON TRIHALIDE WHICH COMPRISES WITHDRAWING FROM SAID FLOWING STREAM A SAMPLE STREAM OF SAID HYDROCARBON; PASSING SAID SAMPLE STREAM, UNDER A PRESSURE SUFFICIENTLY HIGH TO MAINTAIN ALL CONSTITUENTS OF THE SAMPLE STREAM IN THE LIQUID PHASE, TO A PRESSURE REDUCING MEANS; REDUCING THE PRESSURE OF THE SAMPLE STREAM AND PARTIALLY VAPORIZING IT TO FORM A VAPORLIQUID MIXTURE; COMMINGLING A STREAM OF AERATION GAS AND A STREAM OF SUBSTANTIALLY PURE WATER WITH SAID VAPOR-LIQUID MIXTURE; INTIMATELY MIXING SAID STREAM AND DISSOLVING IN THE WATER THE BORON TRIHALIDE PRESENT IN SAID SAMPLE AN ELECTRICAL CONDUCTANCE CELL; AND CONTINUOUSLY MEASURWATER-RICH STREAM; PASSING SAID WATER-RICH STREAM THROUGH TURE TO A SEPARATION ZONE AND WITHDRAWING THEREFROM A STREAM; PASSING THE RESULTANT GAS-HYDROCARBON-WATER MIXING THE ELECTRICAL CONDUCTIVITY OF SAID WATER-RICH STREAM AS A MEASURE OF THE BORON TRIHALIDE CONTENT OF SAID SAMPLE STREAM.
