ABSTRACT:
A flashing feed inlet device is used in a vapor/liquid contacting column, such as a distillation column, to decrease the amount of liquid entrainment and maldistribution of vapor occurring when the liquid feed stream is introduced into the column at a temperature and/or pressure conditions higher than those existing in the column. The entrainment of the liquid and the maldistribution of the vapor are decreased by substantially decreasing the linear velocity of the vapor produced by the flashing of the liquid feed stream.
