Operation Optimization for the Main Stripping Tower in the Tire Cracking Oil Hydrogenation Unit
The initial conditions were set,and a material balance was conducted on the main stripping tower,and the effects of mixed low separation oil temperature,feed position,stripping steam amount,and tower top operating pressure on the desulfurization effect and cooler heat load of the main stripping tower were analyzed and discussed.The results indi-cated that the mixed low separation oil temperature,feed position,stripping steam amount,and tower top operating pres-sure were set to 230℃,the 8th plate,60 kg/h and 0.8 MPa are more reasonable.Under these conditions,the hydrogen sulfide content in the effluent from the tower bottom and the heat load of the cooler were 6.2 μg/g and 1479.1 kW,respec-tively.
