ABSTRACT:
A process for separating gaseous or liquid hydrocarbons in first and second fractionation zones wherein the first fractionation zone employs a side reboiler discharging below the side draw point. A vapor sidestream is removed from the first fractionator below the side draw point and introduced to the second fractionator. The flow scheme permits control of the first fractionator bottoms temperature to match available low level waste heat which may therefore be used in fractionator reboiling duty.
