Petrodist 100 M is a computer controlled crude oil distillation system for semi-automatic operation according to ASTM D-2892.The system is designed for automatic operation of the individual distillation stages, the fraction changes resp. the receiver changes are automatically carried out according to pre-selected boiling temperature or when the receivers are filled up. The vacuum-tight fraction collector contains 9 receivers. The receiver volume is related to the flask size. There are 9 receivers for every distillation stage, thus max. 36 fractions can be obtained with the usual 4 distillation stages. The installation requires water, nitrogen, compressed air and electricity.
