Process for manufacture of liquid fuel components from renewable sources

A method for producing liquid fuel components from renewable oil, the method comprising:

• subjecting a fresh feedstock of renewable oil comprising saturated fatty acids to dilution with an organic lipophilic solvent containing less than 5 ppm phosphorus impurities and less than 10 ppm metal impurities, wherein the organic lipophilic solvent consists essentially of a mixture of iso-paraffins with a carbon chain length of C14 to C18, wherein the fresh feedstock is subjected to the dilution during purification of the fresh feedstock by at least one pretreatment process for removal of phosphorus and metal impurities and for forming a purified feedstock, wherein the pretreatment process comprises a degumming process, wherein the fresh feedstock is subjected to the dilution during the degumming process, and
• subsequently feeding the purified feedstock into at least one post-treatment process for producing liquid fuel components,
• wherein a volume ratio of the organic lipophilic solvent to the fresh feedstock is within a range of from 0.1:1 to 2:1, and
• wherein the purified feedstock contains less than 5 ppm phosphorus impurities and less than 10 ppm metal impurities, wherein the metal impurities comprise Fe, Na, Ca, and Mg.
