  • Method of using an upper discharge in a fluidized bed reactor and system thereof
    Patent number: 8153068
    Abstract: A method according to one embodiment includes operating a reactor or providing a reactor after operation, wherein the reactor includes a bottom section, a bed section above the bottom section, a distributor plate between the bottom section and the bed section, an expanded section above the bed section, and an upper section above the bed section, wherein the bed section has a height H measured from the distributor plate to the expanded section; measuring a concentration of particulates in the upper section of the reactor to obtain a first determined level of particulates in the upper section; and discharging at least some of the particulates from the reactor at an upper discharge point located above 0.55H as measured vertically from the distributor plate based on the first determined level. Additional systems and methods are also provided.
