Melt clarify the pine resin, pressure filtration to remove suspended impurities, measure and put it into the reaction kettle with stirring , vacuum distillation. Control the speed and end of distillation by controling temperature and vacuum degree, steam condensate through the condenser tube, segment received excellent oil, petroleum and heavy oil. After distillation, directly get the material without rosin deep processing. Compared with the conventional method of steam, process greatly simplified. Material loss, low energy consumption, less emission, equipment, versatility, low cost. Short production cycle. Safe and easy operation, comprehensive advantages. Can lay the foundation for subsequent processing.
