The ASTM D 5236 (Potstill) Standard / L-Series / M-Series

The ASTM D 5236 (Potstill) can fractionize crude oil or crude oil residue from 15°C up to 565 °C (at atmospheric equivalent temperature); from atmospheric pressure down to a vacuum of 0,1 Torr.

The column design complies fully with the ASTM D 5236 method. 

In normal operation mode, the plant completes a preheating and evacuation to the first vacuum stage (1 Torr), distilling until a predetermined flask temperature and reduces pressure to 0,2 Torr while continuing distillation.

After the final cut, it carries out a final cooling sequence.There is a special mode which allows (performing / completing – which you prefer) a full distillation including an initial debutanization. 

This is especially interesting for customers who have the knowledge in data conversion from Potstill yields to TBP yields, as it can save up to 80% of the distillation time.
