1. A process for producing renewable hydrocarbon components from triglyceride containing feedstock, said process comprising:
a. hydrolyzing said triglyceride containing feedstock to provide a mixture containing fatty acids, glycerol and water;
b. subjecting said mixture containing fatty acids, glycerol and water to a phase separation to recover an oily phase containing fatty acids, and an aqueous phase containing glycerol and water;
c. subjecting said oily phase containing fatty acids to fractionation to provide a first fatty acid fraction containing at least 80%-wt of free fatty acids having a carbon chain length of C16 or less, of a total fraction weight, and a second fatty acid fraction containing free fatty acids having a carbon chain length of at least C17;
d. subjecting said first fatty acid fraction to:
hydroprocessing to provide a paraffinic renewable aviation fuel component, wherein hydroprocessing comprises hydrodeoxygenation and hydroisomerization, simultaneously or in sequence, or
ketonisation before hydroprocessing to provide a paraffinic renewable base oil, or
a combination thereof;
e. subjecting said second fatty acid fraction to hydroprocessing, wherein hydroprocessing comprises hydrodeoxygenation and hydroisomerization, simultaneously or in sequence, to provide:
a renewable paraffinic diesel fuel component,
a renewable paraffinic technical fluid, or
a combination thereof;
f. recovering renewable hydrocarbon components, comprising renewable aviation fuel component and/or paraffinic renewable base oil, and a renewable paraffinic diesel fuel component and/or a renewable paraffinic technical fluid, as products from steps d and e; and
subjecting said aqueous phase containing glycerol and water obtained from separation of step b, to a step g for producing propanols,
wherein hydroprocessing conditions applied to the first fatty acid fraction in step d differ from hydroprocessing conditions applied to the second fatty acid fraction in step e.
