摘要

A process for the recovery of low-level heat in steam reforming plants by saturating a hydrocarbon gas feed stock with process condensate in a system comprising: (a) injection of process condensate through multiple nozzles into a tubular coil containing multiple streams of hydrocarbon gas feedstock; (b) vaporization of all or part of process condensate by the concurrent heating of the two-phase mixture of hydrocarbon feedstock and liquid in the tubular coil by heat transfer from a low-level heat source such as reformer furnace flue gas or shift reactor effluent; (c) separation of the saturated hydrocarbon gas from any excess liquid condensate, with delivery of the saturated hydrocarbon gas to a steam reforming unit and recycle of excess liquid condensate to the process condensate system.
