Microcomputer salt content analyzer

Product Overview:

Microcomputer salt content analyzerSH-200It is controlled by a microcomputer for measurement and electrolysis, and data processing is performed. The microcomputer integrates the electrolysis current to calculate the amount of electricity required to replenish the consumed Ag+, and calculates the salt content of the sample according to Faraday's law. Suitable for the determination of salt content and inorganic chloride ions in crude oil, residual oil, other oil products, and various industrial water discharge water, it is an ideal instrument for controlling salt content analysis in current electric desalination processes.

IIMicrocomputer salt content analyzerSH-200working 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.
