Abstract: 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.

Abstract: A storage tank system includes a storage tank for storing biological feedstock, a filtering system configured to separate sludge from the biological feedstock, and a water separator configured to separate water from the biological feedstock. A material transfer system transfers biological feedstock from the lower portion of the storage tank via the filtering system to the water separator and, from the water separator, residual biological feedstock from which water has been removed at least partially back to the storage tank. The removal of water reduces unwanted gas generation by microbiological reactions, and safety of the storage tank system is improved.

Abstract: A system for storing biological feedstock includes receiving tanks, storage tanks, and at least one slop tank. The biological feedstock is supplied to the receiving tanks from sources external to the system. Fat separated from the biological feedstock is transferred from the receiving tanks to the storage tanks, and sludge deposited on a bottom portion of each receiving tank and on a bottom portion of each storage tank is transferred to the slop tank. Fat separated from the sludge is transferred from the slop tank to the receiving tanks. Biological material is blended from biological feedstocks. The tanks act in different roles to improve the removal of sludge, and increases the yield of desired biological material.

Abstract: 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.

Abstract: 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° 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.
