What are the key points for the overall control of delayed coking operations? In particular, what details should be paid attention to in the reaction section? I’d like to share some insights from those of us with more experience! ~
What is master control? Please give an example!
The reaction section primarily controls the reaction temperature and pressure; therefore, it is necessary to pay attention to the temperature of the furnace tubes, the temperatures at various points within the coke tower, the pressure at the top of the coke tower, and the height of the coke layer. The actual operations are basically carried out with these factors in mind
Control the reaction temperature, pressure, and recycle ratio to maintain the three equilibria in the distillation column. The most important aspect is preventing coking in the heating furnace.
