The catalytic cracking fractionation system is mainly composed of fractionating tower, diesel stripper, oil refining tank, oil and gas condensation cooling system at the top of the tower, circulating reflux of each middle section and product heat recovery system. Its main task is to reduce the temperature of high-temperature oil and gas from the reaction system, and cut it into fractions such as rich gas, gasoline, diesel oil, oil refining and slurry oil according to the different boiling points of each component, and ensure the quality of each fraction through the control of process factors; At the same time, the high temperature potential energy in each circulating reflux of fractionator can be used as the heat source of each reboiler in the stable system. Some devices also make reasonable use of the low-temperature potential heat source of oil and gas at the top of fractionator.
