Abstract

The disclosure elates to the field of biodiesel production to provide fuel for diesel internal combustion engines. In particular, the disclosure seeks to provide an improved process for manufacturing diesel fuels having at least a component derived from waste natural (non- synthetic) oils which are contaminated with free fatty- acids, especially used cooking oil. Accordingly, there is provided a process for the production of biodiesel from natural oils comprising: providing waste natural oil having a relatively high free fatty acid content, providing virgin natural oil having a relatively low, or zero, free fatty acid content, blending the waste oil and virgin oil in appropriate proportions to produce an oil blend having a target reduced free fatty acid content, stripping the oil blend to produce distilled fatty acids and separating the fatty acids from the oil blend, feeding the oil blend to a transesterification stage thereby to form biodiesel end product. Also provided is apparatus for conducting this process.
