The influence of plate and packed column on the mass transfer of free fatty acids from palm oil mixtures

Stream stripping of free fatty acids from oil and splitting of oil into fatty acids are the key processes in the Malaysian Palm Oil and Oleochemicals industry. Both consumes an enormous amount of high pressure steam to provide heat and vacuum. Typically as much as 30% of the operating costs is due t...
