On-line quality analysis of the crude oil properties is important to allow evaluation of the crude oils at any time.
The newly redesigned MOD-4100 crude analyzer represents a breakthrough in crude oil on-line analysis. It is a single analyzer, that performs on-line a variety of different critical crude oil measurements to provide real-time analytical data, which is highly important for optimized operation processing of crude oils. The new design of the MOD 4100 analyzer system is based on a “Modular Package concept”. It is inspected and tested by the factory, and ready for immediate installation on-site. The following crude oil critical parameters can be measured on-line and correlated to ASTM:
- Salt Concentration (D3230)
- Distillation (D2892, D86)
- SARA (IP-143 and D893-69)
- Emulsion stability (F3045, D4007 and D3707)
- Hydrogen Sulfide content (D5705)
- RVP (D6377 and D323)
- Viscosity (D445 and D2501)
- Water Content (D4928 and D4006)
- Sulfur content (D2622 and D4294)
- Density (D4928 and D1250)
The analyzers are applicable in the oil well, pipes, vessel, tanks, and at any other location in the crude oil supply chain from the oil well during transportation, storage, desalting, and blending until the crude distillation unit. On-line and rapid analysis allows real-time detection of unacceptable levels of quality parameters to take immediate corrective actions.

Crude Oil Distillation
- On-line monitoring of the crude oil properties before, between, and after the desalters enables efficient operation of the desalter, at minimum cost of energy and process chemicals.
- On-line monitoring of the physical properties such as the SALT, H2S, and TAN of the crude oils entering the CDU is also of high importance for evaluating the potential of corrosion and fouling that affect the equipment and the pipelines.
- Indicates the transition period between two sequential crude oil feeds.
- Continuous verification of the entire batch complying with its specifications.

System Advantages
On-line monitoring of the crude oil qualities also plays a critical role in a variety of different crude oil process optimizations.
Crude Oil Blending:
- Optimization of the ratio between crude oil being blended to provide a blend of required physical properties.
- Reduction of blend cost by maximum incorporation of low-cost crudes in the blend
