Abstract:
1. A process for the production of synthesis gas from a hydrocarbon feedstock, comprising the steps of: a. reforming at least a portion of said hydrocarbon feedstock in an endothermic reforming stage in a heat exchange reformer and withdrawing from the heat exchange reformer an effluent stream of primary reformed gas; and b. passing the primary reformed gas from the heat exchange reformer through an autothermal reforming stage (ATR), catalytic partial oxidation stage (CPO) or partial oxidation stage (POX), and withdrawing a stream of hot effluent synthesis gas; wherein the process further comprises the step of splitting the hot effluent synthesis gas into at least a first synthesis gas stream and a second synthesis gas stream, wherein said first synthesis gas stream is used as heating medium in indirect heat exchange in the heat exchange reformer of step (a); and wherein said second synthesis gas stream is directed to a second heat exchanger in which it is cooled by indirect heat exchange to produce a cooled second synthesis gas stream.
