再生系统:燃烧待生催化剂上所吸附焦炭产生的热量,由再生催化剂带到反应器

Regeneration system: The heat generated by burning the coke adsorbed on the spent catalyst is brought to the reactor by the regenerated catalyst to provide the heat required for the reaction. Therefore, the catalytic cracking process is basically a self-heating balance process. As the feedstock oil becomes heavier and the coke yield becomes larger, the regeneration heat is surplus, and this part of the heat is taken away by the production of steam through the external heat extractor of the regenerator. The increase in coke production rate also increases the amount of regeneration air required and requires a larger main fan. The regenerated flue gas passes through the third-stage cyclone separator to separate the catalyst dust (fine powder) carried by the flue gas, enters the flue gas turbine, and uses the pressure of the flue gas to drive the aforementioned main fan that provides regeneration air. The surplus is also used to drive generators to generate electricity. Then, the flue gas is sent to the waste heat boiler to produce steam.

Regeneration system: The heat generated by the coke absorbed on the combustion to be born catalyst is carried from the regenerative catalyst to the reactor to provide the heat required for the reaction, so the catalytic cracking process is basically a self-heating balancing process. As raw oil becomes heavier and the coke yield becomes larger, there is excess regenerative heat, which is removed by producing water vapor through the regenerator's external heat collector. The increase in coke yield also increases the amount of regenerative air required and requires a larger main fan. After the regeneration of the flue gas through the third stage cyclone separator to separate the flue gas carried by the catalyst dust (fine powder), into the flue gas turbine, using the pressure of the flue gas can drive the previously described main fan to provide regenerative air. The excess is also used to drive generators to generate electricity. The fumes are then sent to the waste heat boiler to produce water vapor.
