<p>Cooling of the gas leaving a reactor at high temperature from a process for preparing a gas by partial oxidation of hydrocarbons which may contain free carbon in an indirect heat exchanger with simultaneous steam production, incorporating the improvement whereby part of the cooled gas is recycled, through the exchanger, generally so that the max. temp. of the gas in the exchanger is 1200 degrees C.</p> |
