Standard substance for salt content determination

Overview:

原油Standard substance for salt content determinationThe SH-200 is controlled by a microcomputer for measurement and electrolysis, and performs data processing. The microcomputer integrates the electrolysis current to calculate the amount of electricity required to replenish the consumed Ag+. According to Faraday's law, the salt content of the sample is calculated. It is suitable for determining the salt content and inorganic chloride ions in crude oil, residual oil, other oil products, and various industrial wastewater discharge water. It is an ideal instrument for controlling salt content analysis in current electric desalination processes.

Execution standard: SY/T 0536-94 (ZBE21001-87) Standard for Determination of Salt Content in Crude Oil (Electricity Method).

Technical Specifications:

1. Sample type: Liquid

2. Measurement method: Electricity method

3. Bias voltage range: 0~500mV, freely selected

4. Measurement range: Salt content: 0.2~10000 (NaCl) mg/L, chloride ion content: 0.1 ppm~percentage content

5. Instrument accuracy: less than ± 3%

6. Sampling amount: 1g ± 0.2g

7. Power consumption: 50W

Working Principle:

Crude oil is heated in the presence of a polar solvent, and its salts are extracted with water. After centrifugal separation, the extraction solution is injected into a titration cell containing a certain concentration of titrant using a syringe. The Cl - in the sample and the Ag+in the electrolyte react as follows:

Ag++Cl- →AgCl

Electrolytic anode generates titrant Ag+to replenish the consumed Ag+until the concentration of the titrant returns to its original level. Measure the amount of electricity required to replenish the consumed Ag+and determine the salt content in the sample according to Faraday's law.

Standard substance for salt content determinationIt is a salt content control sample produced by the Institute of Stone Science. The standard sample is a consumable that can be stored in the refrigerator for one year.
