  The Crude Glycerin obtained from the process of Oils / Fats Splitting ( Sweet Water Crude ) OR Saponification ( Spent Lye Crude ) OR Trans esterification ( Biodiesel Crude ) can be converted to Refined Glycerin of different grades ( Chemically Pure , Industrial or Pharma ) by using the following process in sequence .   Drying cum Dearation Distillation & Deodorization Bleaching Salt Decanter or Agitated / Wipe Film Evaporator ( Optional – To improve yield & reduce waste generation )

The inherent harmful factors for human consumption like free fatty acids (FFA), gums, sediments, odoriferous and colouring materials present in crude oils are removed completely to make the oil edible. MECTECH takes special care in all the stages and after undergoing the process of neutralisation, bleaching and deodorisation, the oil is safe and fit for human intake. Degumming / Neutralization Degumming is a process of removing phospholipids to improve its physical stability and facilitate further refining. Presence of phospholipids leads the oil colour rise in high temperature and they can also serve as precursors of oil off -flavor. Free fatty acids, pigments and other impurities are also partially removed by degumming. Mectech follows different types of  degumming processes . These processes are (ie water degumming acid degumming Exzymatic degumming) being selected based on methods of processing, chemicals used and the content of phosphatides in the crude vegetable oil.

Fatty Acid industry is associated with production of fatty acids and glycerine. Both vegetable oils & animal fats are being used as feedstock for fatty acids / glycerine manufacturing. The fatty acids are manufactured as a distillate mixture or a pure fraction. Pure fractions can be obtained either from  fractionation plant or by selectively choosing the feed-stock & carrying out straight distillation. Fat Splitting Plant In  Fat Splitting Plant , hydrolysis reaction of oil / fat is carried out. The reaction takes place at high pressure and high temperature. Triglycerides (fat/oil) react with water to convert into fatty acids and glycerol. The  Fat Splitting Plant  is a high-pressure single tower system. The fatty matter proceeding from battery limits is pre-heated and fed to the de-aerator operating under vacuum. The de-aerated fat is fed via a high-pressure pump to the bottom of the tower. In bottom of the tower, there is a heat recovery section where de-aerated fat isheated by the exiting sweet water. The process water is fed via a high-pressure pump to the top of the splitting tower. In top of the tower, there is a heat recovery section where process water is heated by the discharging crude fatty acids. The high pressure splitting tower is provided with temperature controllers. Fatty Acids Distillation Plant Fatty Acids Distillation plant  is broadly divided into three main section. vis. de-gasification, pre-cut system and main distillation system. These main process section are supported for optimum cooling based on thermostatised water system. Crude fatty acids from battery limit is filtered, pre-heated and admitted to the de-gasifying unit operating under vacuum, where it is dried and de-gasified. Crude fatty acids, from de-gasifier is heated in thermic fluid exchanger and fed to the pre-cut column. The pre-cut column operates under vacuum and is composed of various section; starting from bottom, the main sections are vaporization section, Two sections of distillation packing bed, pump-around section and scrubbing section. From bottom of the column, the product is sent to  Fatty Acid Distillation  column. The main distillation column operates under vacuum and is composed of various section; starting from bottom the main sections are vaporization section, stripping section, one set of washing section, one pump-around section and one scrubbing section     Soap noodles Fatty acids sourced from Palm stearin, Rice-Bran Oil, Coconut Oil, Tallow…etc. are typically blended together to form fatty acids blend for soap manufacturing. Today all premium grade soaps are being manufactured from blend of the distilled fatty acid. Mectech's Revolutionary on-line seperation system for fatty acid and glycerine phase Working principal Driving force for Static Separator is gravity flow. The Separator is a static device having highly specialized internals and level controller. The internals are so specially designed that, the disperse phase smaller droplets gets agglomerate on the surface to form bigger globules. This enhances process of separation of the two phases. Fatty Acids Distillation Column The agglomerated bigger globules represents Free Disperse Phase and is padded through an environment where sufficiently quiescent conditions are maintained, so that disperse phase globule rises to the continuous phase surface; forming a layer of disperse phase liquid. The removal of both phases from the separator is through level controller. Both phases are freely discharged under gravity. Advantages Each plant component is designed to MICRO level; hence performance of each component is controlled to the required level. Our plants are 100% custom-built and we do not sell the “standard plants”. It results in good “Turndown” Ratio for plant operation.. Customer need not compromise on his requirements. We can supply the plants of required capacities at desired parameters such as utility consumptions, operability, plant life as per customer’s request.
