Abstract

A control procedure whereby a secondary control viable (such as regenerator air velocity) is controlled or maximized at the same time as the carbon balance of the unit is kept under control. A digital computer such as the IBM 1800 is used to solve the algorithm for carbon balance control, and perform a logic sequence to select the proper control step to be taken (e.g. choosing between the flue gas slide valve and the regenerated catalyst slide valve).
