• What is bleaching ?
• Why is bleaching really done ?
• It is based on ADSORBTION
• it is Represented by an equation developed by a great scientist Freundlich log(x/m) = logK + nlogc • Process will continue till Thermodynamic equilibrium is reached
• Temperature should be maintained between 90-110 degree Celsius. • Contact Period of 20 – 30 min.• Bleaching is performed under reduced pressure• Type and amount of bleaching Agent highly influence the process parameters .
2 major processes include –• Batch process
A : Bleacher A1 : Oil inletB : Barometric condenser B1 : Oil adsorbent outletC : Vacuum pump C1 : Steam inletD1: Condensate outletE1 : Bleaching Material inlet F1: Water Inlet
• Continuous process
: Crude Oil Inlet 1: Continuous bleacherB: Oil-Earth suspension to be filtered 2: Earth tankC: Bleached oil inlet 3: Earth dosing unitD: Bleached oil outlet 4: MixerE: Water Inlet 5: Earth-oil pumpF: Steam Inlet 6: Heat Exchanger 7;Cooling unit 8;Condenser; 9;pump r 1
• Fuller’s Earth-• It is a natural clay which is very adsorbtive• Mainly consists of minerals that belong to the aluminium silicate family• Main component is bentonite
• For most bentonites necessary surface area and pores need to be created • Activation is done with acid
• Main component of bentonite is montmorillonite
• Acid activated Bleaching Earth-• Its Catalytic property is self explained by the acid status.• Its maximum importance comes with its property of degradation of peroxide• Results in the formation of trans fatty acids
• Activated Carbon -
•Can be derived from a variety of coal• Contain micropores, mesopores & macropores• It has a large adsorbent surface in a relatively small volume.
