Fractionator operation
Thread Content
The top temperature of the coking fractionation tower remains high, and it is higher than the temperature at which extraction takes place in a fixed cycle. If both the set circulation rate and the intermediate flow rate are high, the top temperature cannot be reduced, even though all the top circulation air coolers are in operation. Everyone, let’s also discuss what’s going on.
Gas cold reflux can be put into use; it is necessary to check the top temperature thermocouple, the top circulation flow meter, and the mid-section flow meter, and conduct a thorough investigation from various aspects.
Start from the bottom of the tower, reduce the temperature, appropriately increase the interruption and top circulation rates, thereby lowering the temperature returning to the tower.
