An integrated design for biodiesel production process from rapeseed vegetable oil is developed. The process simulation software ASPEN Plus version V7.0 is used as a computer aided process engineering (CAPE) tool. The process consists of two steps. The acid-catalyzed 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. Different types of vegetable oil are studied. Among them the rapeseed oil is chosen as raw material for biodiesel production because the rapeseed oil oleic acid content is high and because it is the most common oil in Romania. Moreover, the detailed composition of the rapeseed oil is taken into account. This is determined experimentally by transesterification combined with gas chromatography coupled with mass spectroscopy (GC-MS) and Fourier transform infrared-attenuated total reflectance (FTIR-ATR) spectroscopy.
