Abstract

Processes and apparatus for treating a pressurized feed stream capable of undergoing an endothermic reaction are disclosed. The process includes dividing the feed stream and heating a portion of the feed stream in an endothermic reaction zone so as to produce an endothermic reaction product, subjecting that product to a secondary processing step which is favored by a reduction in temperature, expanding the other part of the feed stream, indirectly contacting the expanded portion of the feed stream thus produced with the endothermic reaction product in order to reduce the temperature of the endothermic reaction product and increase the temperature of the expanded portion of the feed stream, and utilizing the expanded portion of the feed stream as means for adding heat to the initial portion of the feed stream sent to the endothermic reaction zone.
