The present invention provides an improved and efficient biorefining of crude tall oil (CTO) in to valuable fuels and fine chemicals. According to a first aspect of the present invention there is provided an efficient process for the production of refined tall diesel (RTD) or TOFA, specifically the combined production of RTD or TOFA and RA (resin acid(s)) from a CTO. According to yet another aspect of the present invention there is provided a process for the production of an optimised RTD and also such an optimised RTD composition in itself, said RTD composition comprising at least RA, FA (fatty acid(s)) and also CST (crude sulphate turpentine(s)). Furthermore, the present invention is also directed to an improved pre-treatment process for the removal of impurities from a CTO.
