An integrated design for biodiesel production process from rapeseed vegetable oil was developed. The process simulation software ASPEN PLUS was used as a CAPE tool. The process consists of two steps. The acid-catatyzed pre-treatment achieves total conversion of free fatty acids and partial conversion of triglycerides. This is followed by an alkali-catalyzed step where high conversion of triglycerides is achieved. Compared to other designs reported in the literature, each operation which is common to both steps is performed in one unit, leading to smaller investment cost. Moreover, the detailed composition of the rapeseed oil was taken into account. This was determined experimentally by transesterification combined with gas chromatography and IR spectroscopy. Considerations regarding the importance of the physical properties during the process simulation activity are also presented.
