Test Method
Salt content is determined by measuring the conductivity of a solution of crude oil in a polar solvent when subjected to an alternating electrical current. Salt content is obtained by comparison of the resulting conductance to a calibration curve of conductivity versus salt content of known mixtures. Features and Benefits • Conforms to ASTM D3230 test specifications • Measures salt content, conductance, and temperature of crude oil samples • Ideal for laboratory or field applications Features and Benefits • Conforms to ASTM D3230 test specifications • Measures salt content, conductance, and temperature of crude oil samples, and pH measurements of aqueous samples • Portable for field or laboratory testing with up to 8 hours of continuous operation from internal Ni-Cd rechargeable batteries ( extended battery-powered operation option available) • 18-bit analog-to-digital converter for high precision • 24kB RAM dedicated for data storage ( about 500 test results) • Data can be easily uploaded in a comma delimited format to a PC with Windows® 95/ 98/ NT-based software via an RS232 serial data port Salts-In-Crude Analyzer A precision microprocessor-based instrument for determining salt content, conductance, and temperature of crude oil samples in accordance with ASTM D3230. The analyzer measures conductivity over three ranges ( 0-2, 2-20, 20-200 µ S) with automatic range selection. Temperature is measured in the range of -5 to 55° C. Reports conductivity at the temperature of measurement and conductivity corrected to 25° C, allowing for standardization of field measurements at different temperatures. Salt content is obtained by reference to a calibration curve of conductivity versus salt content of known mixtures. All functions including calibration are controlled by simple keypad entries. Compact design makes this unit ideal for laboratory or field applications. Includes signal processor, display module, temperature / conductivity probe with three-foot cable, 100mL tall-form sample beaker, 9 volt battery, 115 or 220 VAC adapter, and padded nylon carrying case. The advanced model utilizes the latest low-voltage, synchronous detection technology with a high-precision 18-bit analog-to-digital converter for conductivity measurements and a high-accuracy thermistor array to measure sample temperature. Automatically calculates salt concentration directly from acquired temperature and conductivity values. Measures conductivity over four ranges 0-2, 2-20, 20-200, and 200-1500 µ S with automatic range selection. Self-calibration feature allows operator to adjust for any drift without re-entering standard temperature curves. Complete data storage of test results with 24Kb RAM for about 500 test results. Test data can be easily uploaded in a comma delimited format to a PC with Windows® 95/ 98/ NT-based software via an RS232 serial data port. Easy-to-read alpha-numeric display shows any four of the following parameters at one time as chosen by the operator: salts, conductance, conductance @ 25° C, pH, pH millivolts, temperature ( ° C or ° F) , internal and external battery voltages, date, time, logging ID, and ID increment value. Portable for field or laboratory testing with up to 8 hours of continuous operation from internal Ni-Cd rechargeable batteries on advanced model. Extended battery-powered operation option available.
