<p>A process is described for both (i) quenching a fuel gas mixture including at least one gaseous hydrocarbon foulant (described more particularly herein) and (ii) removing at least a portion of the foulant without substantial formation of mist thereof in the gas mixture. The process includes contacting a flow of the gas mixture with a liquid jet spray of large droplets of a coolant mixture comprising liquid water and viscous liquid hydrocarbon. The contact is maintained for a sufficient period of time such that at least a portion of the foulant is liquefied and collected on the droplets. The droplets having foulant thus deposited thereon are removed from the treated gas mixture in a separation zone.</p> |
