Slide 3: Chemical Refining
Chemical Refining Still most widely applied refining process * Independent of crude oil quality (‘forgiving’ process); * Usually gives good refined oil quality (‘effect of caustic’); * Most suitable process for stand-alone refineries; But, with its known drawbacks * High neutral oil losses in the so
Slide 4: Developments in Chemical Refining
Developments in Chemical Refining Better value-enhancement of soapstock * Dry chemical refining with CaO (formation of Ca-soaps); * Chemical refining with KOH (formation of K-soaps); * Not applied on industrial scale (not consistent, too high operating cost,..) Mechanical improvements * Centrifugati
Slide 5: Nano Reactors
Nano Reactors® • Hydrodynamic cavitation principle • Effects are generated by pumping two liquids (e.g. oil + water) – from which at least one is low boiling - at high pressure through a specific designed device (nano-reactor) • Formation of small ‘nano’ bubbles (‘cavities’) with release of large ma
