Many major process units in the chemicals and oil and gas industries, such as crude distillation and vacuum towers, natural gas liquids recovery and fractionation, gas plants associated with petroleum ...

The Crude Distillation Unit (CDU) The crude distillation unit (CDU) is probably the highest throughput process unit on the entire refinery, and considering that commonly there may be two, three, or ...

We executed the low-cost modifications to the unit just as I'd described them to John, and almost immediately the crude tower overhead was delivering naphtha with an ASTM D-86 distillation ...

Crude-unit process flow schemes should focus on crude properties, processing objectives, and design fundamentals. Heavy oil is inherently more difficult to vaporize because there is less light ...

FT-NIR technology provides a multi-component analysis of crude oil’s physical and chemical properties before it enters the Crude Distillation Unit (CDU). This real-time data enables refiners to ...

Image Credit: ABB Inc. You will also learn about the optimal optical configuration for FT-NIR crude oil analysis. It advocates for using the combination spectral range (4000–4800 cm-1) instead of the ...
