[ Having described my invention, what I now claim is:] [1.] A method for improving the capacity of an uncontrollable discharge shell and tube membrane dehydrator comprising:flowing a feed stream into the tube side of the dehydrator, the feed stream comprising a gas containing a permeate to be removed to lower the dew point of the gas to a target dew point;flowing the feed stream in the range of from 12.27% by volume to 36.9% by volume through the walls of the tube(s) into the shell side, said flow through the walls of the tubes comprising an uncontrollable purge stream;discharging the gas from the dehydrator at a target dew point;introducing a controlled purge stream into the shell side to augment the uncontrollable purge stream, said controlled purge stream having a dew point lower than that of the feed stream; andincreasing the flow rate of the feed stream flowing through the dehydrator while maintaining the dew point of the gas discharged from the dehydrator at the target dew point.
