產品特色

 

Vacuum residue after heat exchanged with feedstock oil, it enters in to oxidation tower. As air is blowing from the bottom of oxidation tower, vacuum residue in the tower is oxidizing reacting with air. Fresh water is sprayed from the top of oxidation tower to control the temperature of gaseous phase temperature not higher than 160 c.
Tail gas from the top of oxidation tower will flow in to a saturator, tail gas contact with water and cooled down to have the dirty oil separated away from gas. The residual gas discharged from the top of saturator will flow in to water sealed tank. And residual gas discharged from the top of water sealed tank will be sent to residual gas incinerator, which will be discharged to air after burnt in a incinerator. The heat energy produced from tail gas can be used for heating up of the feedstock oil before entering in to vacuum tower.
The dirty oil discharged from saturator will flow in to residual oil tank, and then pumped out of unit periodically. Circulating diesel is pumped in to asphalt-diesel heat exchanger through diesel circulating pump to make its temperature increased from 65c to 140c. The hot diesel will be cooled through diesel cooler with circulating water to have it down to 65c. The cooled diesel will be sent back to diesel circulating tank.
Compressed gas from the system pipe lines enters in to bottom of oxidation tower.
Saturator, residual oil tank, diesel tank are in the same case.
The degree of asphalt from 60-120 is controlled by the vacuum distillation extraction level, oxidation duration and air blowing quantity.
