Phase Technology’s 70Xi series online analyzers optimize your refining process with fast, reliable, real-time testing of product streams. With the benefit of process control, you can be closer to specifications to maximize the yield of high-value products and reduce giveaway.
Including a dedicated process analyzer in your refinery’s flow from distillation lets you get quicker test results with better ASTM reproducibility. Online analyzers are a smart investment to ensure that quality control is tight at every step of the refining process.
Phase Technology online analyzer systems are ruggedly built for continuous, uninterrupted measurement. Their robust, explosion proof construction means you can rely on them to operate in even the most extreme and hazardous conditions.
Cloud Point
Monitor the cloud point of the diesel stream coming from the crude distillation unit. Close control of the cloud point allows you to reduce the amount of kerosene which must be used to product specification heating oil during the winter.
Freeze Point
Monitor the freeze point of naphtha or kerosene streams coming from the distillation unit. Close control of freeze point helps you maximize yield of high-priced products.
Pour Point
Monitor the pour point of the diesel stream from the crude distillation unit. Close control of pour point allows you to decrease the amount of kerosene which must be added to produce specification product during the wintertime, or adjust the amount of kerosene to be added to higher-priced jet fuel feeds.
