Paraffin Oil Recovery Process: tail gas first enters paraffin absorption tower, and then comes the counter-current absorption of paraffin
and tail gas, which can reach the ideal state when the stainless steel packing has large surface area. The solvent content in discharged liquid
paraffin (called rich oil) is not more than 5%,so as to ensure the maximum absorption rate.
The paraffin rich oil is pumped into the heat exchanger to exchange heat with paraffin lean oil,and then goes to paraffin heater,and finally
enters paraffin analysis tower.In the analysis tower,the steam-liquid heat exchange is conducted on the surface of stainless steel packing
surface with direct steam and rich-oil paraffin,which can remove the solvent in the paraffin. This kind of paraffin,also called lean oil,
exchanges heat with rich oil, and then is cooled to the ideal absorption temperature through the cooler. Next,it enters absorption tower
for recycling. The gas mixture from the analysis tower enters energy saver,and the tail gas from the absorption tower is discharged from
workshop with the fan. In solvent recovery system, the solvent enters the holding tank through water tank, and the condensed waste water
is discharged from water tank.If the tail gas contains certain solvent, cook it with the cooker to make it meet the emission requirements.
