<p>The present invention relates to a process for quenching the effluent gas of a furnace comprising :
a) providing a furnace comprising a radiant zone enclosure means having a plurality of tubes disposed therein, an inlet means for introducing the process fluid into the tubes, means for exposing the external surface of the tubes to radiant heat for heating said process fluid and thereby produce an effluent gas,
b) providing a quench zone having a plurality of quench tubes in which the effluent gas is passed and such as the inlet of one quench tube is connected to the outlet of one or more tubes of the radiant zone,
c) recovering the effluent gas after it has been cooled in the quench tubes, wherein,
at least a part of the quench tubes and advantageously all the quench tubes are tubes having means inside of it, on all the length or a part of the length, to promote turbulent flow. The present invention also relates to a quench exchanger to carry out the above process.</p> |
