Operation of the air cooler in the conversion unit
Thread Content
Dear sea friends, regarding the operation of large-scale coal chemical shift units, where air coolers are used in the unshifted section to reduce the temperature of the process gas
In a conventional setup, the high-temperature waste heat from the transformation process is used to preheat demineralized water and boiler feed water； The low-temperature waste heat is cooled by circulating water. Of course, using an air cooler is definitely feasible.
It is generally based on the principle of heat recovery.
