Values may range from 5 to 9, depending on how good are your reactor stripper performances. For a defined kind of stripper and stable operative conditions, the value doesn’t change too much. In my opinion, you may observe in your unit at maximum +/- 0.5 of variation due to normal operative. For a bigger change, you have to modify the structure of stripper and steam distributors.
