ABSTRACT:
Additional waste heat recovery from a high temperature reaction effluent is effected by cooling the effluent in a shell and tube heat exchanger, having continuous tubes, with the shell being divided into two sections. In the first section, the effluent is cooled by indirect heat transfer with water at a pressure to generate medium pressure steam, and in the second section, the effluent is cooled by water which is at a pressure to generate low pressure steam or a pressure to effect preheating thereof without vaporization. Heat recovery is effected with a minimum pressure drop.
