What are the “three” principles of the Cat reduction process? Answer: (1) Three lows: low-temperature effluent, low-temperature reduction, and a period of low-load operation after reduction ； (2) Three stabilities: temperature stabilization, H2 supplementation stabilization, and water output stabilization ； (3) Three prohibitions: It is not allowed to raise the temperature while introducing H2, it is not allowed to allow moisture to enter the tower, and it is not allowed to have water exit at high temperature for an extended period of time ； (4) Three controls: controlling the hydrogen supplementation rate, controlling the CO2 concentration, and controlling the hourly water output.
(1) Three lows: low-temperature effluent, low-temperature reduction, and a period of low-load operation after reduction; (2) Three stabilities: stable temperature increase, stable H2 supplementation...
“The “three” principles: (1) three lows – low temperature of the effluent, low H2 reduction level, and a low-load operation period after reduction. (2) Three stabilities: stable temperature rise, stable H2 supplementation, and stable water output. (3) Three prohibitions: It is prohibited to raise the temperature while using H2, it is prohibited to allow moisture to enter the tower, and it is prohibited to discharge water at high temperature for extended periods of time. (4) Three controls: controlling the hydrogen addition rate, controlling the CO2 concentration, and regulating the hourly water output.
