A method for treating a lipid material containing phosphorous and/or metal compounds is described. The method includes providing the lipid material, preheating the lipid material, to obtain a preheated lipid material, heat treating the preheated lipid material in a heat treatment step, to obtain a heat treated lipid material, and optionally post treating the heat treated lipid material in a post treatment step.

Method for treating lipid materials

Present disclosure relates to a novel process for purification of lipid material for further use as such as, for example, a source of fuel of chemicals.

Apparatus and method for heat treating a feedstock comprising a lipid material

A method of purifying biomass-based lipid material, as disclosed includes providing a feed of biomass-based lipid material; optionally drying the feed; removing oxygen from the feed under reduced pressure; heat treating the feed at 180 to 300&#xb0; C. under reduced pressure to solidify at least part of phosphorous and/or metal containing impurities, simultaneously distilling off at least part of free fatty acids and low molecular weight nitrogen compounds, to obtain at least a fraction containing free fatty acids and low molecular weight nitrogen compounds, and heat treated biomass-based lipid material containing degraded phosphorous and/or metal containing impurities in solid form; and removing the solid degraded phosphorous and/or metal containing impurities from the second fraction.
