6 Developments in degumming Enzymatic Degumming* PL-C on high PL-containing crude oils (RSO, SBO)* PL-A on crude/WDG oilsMain driverHigher Oil Yieldsoyarape
7 More intensive mixing requiring higher energy input Alkali Neutralisation - DegummingMORE EFFICIENT GUMS/FFA REMOVALUsing less chemicalsTrend towards more intensive mixingStatic Dynamic High Shear Ultra High Shear(single stage) (multi-stage)SilversonIKAMore intensive mixing requiring higher energy inputHow to improve efficiency further ?
8 Generation, growth and collapse of bubbles Nano ReactorsNano ReactorsGeneration, growth and collapse of bubblesRelease of large magnitudes of energy over small location(high energy density)Locally very high temp/pressure with overall ambientconditions‘Mechanical’ Effects*High turbulence*High shear forces*Fine emulsions‘Chemical’ Effects*Fragmenting of molecules*Formation of radicals
9 Can Nano Reactors be applied in Oil Processing ? POSSIBLE APPLICATIONS OF NANO REACTORSProcess intensification (faster-higher yield-more selective)Cell disruption (biotechnology)Microbial disinfection/destruction contaminantsMany other specific applicationsCan Nano Reactors be applied in Oil Processing ?Ref : Gogate – Chemical Engineering and Processing 47 (2008),
10 Acoustic Process ACOUSTIC PROCESS (SONOCHEMISTRY) *No industrial application due to inherent drawbacks* Effect depends on distance from source (not uniform)* Batch process, not suitable for large scale processing* High energy requirement* Generated by Ultrasound waves*Tested successfully for degummingMoulton and Mounts (1999)> 90 % PL removal
11 Typical velocity and pressure profile in a hydrodynamic Nano reactor Hydrodynamic Nano ReactorsHYDRODYNAMIC NANO REACTORS* Less studied than ultrasound process* Generated by passage of a liquid through a constriction* Much more energy efficient than acoustic process* Suitable for larger scale, continuous processesTypical velocity and pressure profile in a hydrodynamic Nano reactor
12 Proprietary design of CTI Nano-ReactorsNANO-REACTORS* Unique internal geometry* Generation of very small ‘nano’ bubblesin liquid streams* Liquids (homogeneous/heterogeneous)are fed to nano-reactor with HP pump* Mechanical and chemical effects- Formation of very fine emulsions- Increased surface area- Strong shear forces- Activation of atoms, molecules- Formation of radicals- Initiation of chemical reactions* Reactor, more than just a good mixerProprietary design of CTI
14 Nano-NeutralisationTM - Patent pending technology- Add-on process to existing oil refineryneutralisation system- Process benefits (industrial proven)No addition of H3PO4 (NHP converted in HP in nano-reactor)No acid retention tankLess NaOH required (no need for H3PO4 neutralisation)Less soaps in nano-neutralized oil reducing need for silicaor wash waterImproved oil yield due to improved separation of soapstock(Less neutral oil/no salts in soapstock)14
17 Nano-NeutralisationTM Industrial plant : 500 TPDProven Process Advantages90% less phosphoric acid40-50% less caustic sodamin. 0.2% extra refined oil yieldless silica consumption17
18 Still in testing phase, not proven yet Other possible applications1. Nano-degumming of crude/WDG oilsDeep degumming to allow physical refining2. Nano-degumming of palm oilReplacing the ‘dry’ phosphoric acid degummingAlso suitable in biodiesel feedstock pretreatment3. Enzyme assisted nano-degummingStill in testing phase, not proven yet
19 Summary - Conclusions* Efficiency, Quality and Sustainability are key criteriafor new/improved processes in edible oil refining* Enzymatic degumming meets all these criteria andis therefore being applied more* Hydrodynamic Nano Reactors is interesting technology for edible oil refining* Nano-neutralisation is being implemented onindustrial scale* Nano-degumming (in combination with enzymes) istested on lab/pilot scale
