The minor blowing is intended for cooling the coke; since the temperature inside the tower is still high at first, it’s not possible to use cold coke water directly. Moreover, the minor blowing helps to push any remaining oil and gas in the tower into the distillation tower, thereby addressing the issue of insufficient gas flow in the distillation tower caused by the recent change in operation mode. For more details, you can refer to the books posted on the first floor – they are very useful.
Additional note: Cool the coke, recover oil and gas from the old tower, and purge the fresh coke channels to prevent sticking due to sedimentation
