Silver refining plant

This Degumming section is the first stage in Refinery plant. The purpose ofdegumming is to remove phospholipids or gums from the crude oil. Twotypes of phospholipids are present in crude oils according to their level ofhydration, i.e., hydratable and nonhydratable ones. After addition of water(1-3%), most of the phospholipids are hydrated and are insoluble in the oil.The hydrated compounds can be efficiently separated by filtration orcentrifugation and the non-hydratable compounds still remains in the oilafter this section. This separation of gums and soap from the oil is done by highly trustedMACFUGE equipment which are designed for centrifugal separation ofsolid-liquid, liquid-liquid-solid, liquid-liquid, in all its versions, types andmaterials. MACFUGE separator is a product of Servizi Industriali SRLlocated in Italy, is a partner with Ferro Oiltek for the supply of macfugeseparator in India. Depending on the oil composition, the degumming step can be eliminatedas the phosphatides are also removed along with the soaps during thenext step of neutralization. However, degumming is mandatory forphysical refining and the content of phosphorus after degumming shouldbe lower than 10 mg/kg. In Ferro's Degumming section, the main equipments are Reactor vessels,Knife-mixtures, Centrifuge separators, Plate type heat exchangers, etcalong with various sub-parts like flowmeters, pumps, control valves, hot-and cold-water tank, strainers, etc.
