Integrated process for producing biodiesel by carrying out the steps of saline demulsification, distillation and esterification of fatty acids and derivatives thereof

摘要

The current invention refers to an integrated process for the production of biofuels, through the application of integrated saline demulsification, distillation and esterification stages for fatty acids and its derivatives in a process involving the breakdown of fatty acids stable emulsions and its derivatives through the isolated or joint utilization of physical processes, as well as saline demulsification of greasy residue denominated from aqueous emulsions, developed in such manner as to promote a suitable destination for such residue, such as the use for the production of biofuels, more specifically, biodiesel. The process proposed herein employs a raw-material purification methodology, which implies in better yields in the production of biodiesel through physical processes, such as sifting, filtration, and distillation of the extracted grease, followed by an esterification and transesterification process.
