SALTS IN CRUDE OIL - ELECTROMETRIC METHOD

SALTS IN CRUDE OIL, ELECTROMETRIC METHOD

ASTM D 3230

DEFINITION
This test method is based on the conductivity of a solution of crude oil in a polar solvent when subjected to an alternating electrical stress.

The sample is dissolved in a mixed solvent and placed in a test cell consisting of a beaker and two parallel stainless steel plates.

An alternating voltage is impressed on the plates and the resulting current flow is shown on a milli-ammeter. The salt content is obtained by reference to a calibration curve of current versus salt content of known mixtures.

CHARACTERISTICS
  • Digital readout of both current and voltage for easy checking, continuously adjustable from 0 to 300 VAC
  • Continuous adjustment of test voltage between 0 and 300 VAC
  • Compact unit
  • Very easy to operate through single selection switch for calibration, standby and measurement.
  • Supplied with 25 k non-inductive resistor for calibration

    • SPECIFICATION
    C.E. labelled tester for determination of salts in crude oil including digital display of both current and voltage, easily and continuously adjustable.

    Adjustable current between 0 and 300 VAC, very easy to operate fully according to the standard
