On-line measurement of the salt concentration in crude oil plays an important role in the crude oil chain, from the well-head until entering the crude distillation unit. The MOD-4100-S is an on-line salt-in crude oil analyser, which is designed to provide real-time analytical data on the salt content in crude oils. Its technology correlates with ASTM D3230, an electrometric method, that determines the salt concentration in crude oil by measuring the conductivity of a sample of crude oil a mixture of xylene, and a mixed solvent of Methanol and Butanol.

The MOD 4100-S salt in crude analyzers is applied to measure the salt content in the entire crude oil chain, from the oil well, during transportation and storage, during blending, and before and after entering the desalter.

The integrated sampling handling and conditioning systems of the MOD 4100-S salt-in crude analyzers guarantee the sample enters the analyzer at the proper conditions that are required by the analyzers.
