Changes in FCCU catalyst and in process conditions have permitted reductions in the CO content of the gases leaving the unit. These changes also result in the gas temperature to the CO boiler increasing from the 1000F (538C) level to as high as 1450F (788C). New heat recovery boilers on FCC units are designed for these new process conditions.
