6 Science behind Technology6www.desmetballestra.com Developments in degumming Enzymatic Degumming soya rape * PL-C on high PL-containing crude oils (RSO, SBO) * PL-A on crude/WDG oils Main driver Higher Oil Yield

7 Science behind Technology7www.desmetballestra.com Alkali Neutralisation - Degumming Trend towards more intensive mixing Static Dynamic High Shear Ultra High Shear (single stage) (multi-stage) Silverson IKA How to improve efficiency further ? More intensive mixing requiring higher energy input MORE EFFICIENT GUMS/FFA REMOVAL Using less chemicals

8 Science behind Technology8www.desmetballestra.com Nano Reactors Generation, growth and collapse of bubbles Release of large magnitudes of energy over small location (high energy density) Locally very high temp/pressure with overall ambient conditions Mechanical Effects *High turbulence *High shear forces *Fine emulsions Chemical Effects *Fragmenting of molecules *Formation of radicals

9 Science behind Technology9www.desmetballestra.com POSSIBLE APPLICATIONS OF NANO REACTORS 1.Process intensification (faster-higher yield-more selective) 2.Cell disruption (biotechnology) 3.Microbial disinfection/destruction contaminants 4.Many other specific applications Nano reactors Can Nano Reactors be applied in Oil Processing ? Ref : Gogate – Chemical Engineering and Processing 47 (2008),

10 Science behind Technology10www.desmetballestra.com 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 degumming Moulton and Mounts (1999) > 90 % PL removal

11 Science behind Technology11www.desmetballestra.com Hydrodynamic Nano Reactors HYDRODYNAMIC 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 processes Typical velocity and pressure profile in a hydrodynamic Nano reactor

12 Science behind Technology12www.desmetballestra.com Nano-Reactors NANO-REACTORS * Unique internal geometry * Generation of very small nano bubbles in 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 mixer Proprietary design of CTI

13 Science behind Technology13www.desmetballestra.com Nano- reactor NaOH Nano-Neutralisation TM Standard Neutralisation Nano- Neutralisation

14 Science behind Technology14www.desmetballestra.com - Patent pending technology - Add-on process to existing oil refinery neutralisation system - Process benefits (industrial proven) No addition of H 3 PO 4 (NHP converted in HP in nano-reactor) No acid retention tank Less NaOH required (no need for H 3 PO 4 neutralisation) Less soaps in nano-neutralized oil reducing need for silica or wash water Improved oil yield due to improved separation of soapstock (Less neutral oil/no salts in soapstock) Nano-Neutralisation TM

15 Science behind Technology Nano-Neutralisation TM Industrial plant : 500 TPD

16 Science behind Technology16www.desmetballestra.com Nano-Neutralisation TM FeedstockWater-degummed soybean oil ( ppm P; % FFA) Nano-neutralizationClassical caustic refining Process parameters -Phosphoric acid (ppm) -NaOH (% 16.6 °Be) -Pressure (bar) -Temperature (°C) Refined Oil Quality -P-content (ppm) -Ca & Mg (ppm) -FFA (%) -Soaps (ppm) 1-3 < 1 < 0.03 < < TPD Nano-neutralisation of soybean oil Industrial data

17 Science behind Technology Nano-Neutralisation TM Industrial plant : 500 TPD Proven Process Advantages - 90% less phosphoric acid % less caustic soda - min. 0.2% extra refined oil yield - less silica consumption

18 Science behind Technology18www.desmetballestra.com Other possible applications 1. Nano-degumming of crude/WDG oils Deep degumming to allow physical refining 2. Nano-degumming of palm oil Replacing the dry phosphoric acid degumming Also suitable in biodiesel feedstock pretreatment 3. Enzyme assisted nano-degumming Still in testing phase, not proven yet

19 Science behind Technology19www.desmetballestra.com Summary - Conclusions * Efficiency, Quality and Sustainability are key criteria for new/improved processes in edible oil refining * Enzymatic degumming meets all these criteria and is therefore being applied more * Hydrodynamic Nano Reactors is interesting technology for edible oil refining * Nano-neutralisation is being implemented on industrial scale * Nano-degumming (in combination with enzymes) is tested on lab/pilot scale
