Feedstock pretreatment is one of the most stringent and critical steps in the manufacturing of biodiesel. It not only governs the quality and yield of the product but also enables us to use low-cost feedstock and thus helps to contribute toward the circular economy.

Kumar’s pretreatment unit (PTU) is uniquely designed to treat feedstock from various sources and efficiently removes all impurities such as gums, metals, moisture, polyethylene, and free fatty acids with minimum energy consumption and minimum effluent generation.

Biodiesel is a product of a Transesterification reaction in which oils/fats are reacted with methanol in the presence of a sodium methylate catalyst. These plants contain various equipment, such as storage tanks, esterification and transesterification reactors, and distillation columns, to process the raw materials and purify the final product.

Kumar supplies the conventional biodiesel plant to cater to various customer requirements, but also provides the state-of-the-art technology called Arisdyne's CFC™ (Controlled Flow Cavitation™) technology, which guarantees the higher yield, lower chemical consumption, and thus lower production cost.

Distilled biodiesel is produced by fractionating methyl esters under vacuum and high temperature. This ensures fuel stability, purity and the production of specialty ester fractions for industrial use.

Biodiesel distillation is a process of distilling methyl esters under vacuum and high temperature to produce distilled biodiesel. The distillation column consists of structured packing to fractionate heavy and light phases. The bottom residue, i.e. pitch, is sent to storage after distillation. The fractional distillation of methyl esters is used to make pure fractions used in the manufacture of specialty chemicals.

Glycerine from biodiesel production is dried, distilled and bleached to produce refined grades. These are suitable for diverse applications in pharmaceuticals, food and industry.
