Advancements in spectrometry are rapidly becoming adopted for in-line and real-time measurement of color and moisture in many manufacturing processes. Whether pigment authentication in paints, moisture content in pharmaceutical powders, or the detection of crude oil contamination in refined products enhances productivity, lowers product loss, improves process reliability, and assures consistent quality.
Some refiners employ crude oil to cool and condense the crude tower overhead vapor stream. If a leak develops in this heat exchanger, crude oil can leak into the naphtha or light straight—run product. At the top of the refining chain, crude contamination at this point can have an impact on all downstream processing.
A spectrometer probe installed in a flow cell on these streams can warn of leakage of crude oil into the light straight—run or naphtha streams. A similar application could be made on the crude / pump-around reflux or crude/product exchangers. A probe could also be installed on the atmospheric gas oil stream to warn unit operators if residual material is being entrained into this stream. A similar application could be made on the gas oil stream from the vacuum tower.
Flow cell spectrometry is an ideal choice for measuring contaminants in different scales at side streams for Light Naphtha and at the feed stock for Hydro treater to produce Gasoline to avoid detrimental equipment damage to Hydro-treaters. Similar applications are in the Heavy Naphtha side stream feeding into the Catalytic Reformer to produce Gasoline and Aromatics.
