Gas quench device for mixed-phase reactors
Abstract
Abstract APPARATUS FOR INTRODUCING QUENCH GAS TO PACKED-BED REACTORS, WHICH APPARATUS IS SUPPORTED WITHIN THE PACKEDBED ITSELF. THE APPARATUS COMPRISES A PIPING ARRANGEMENT SUPPORTED WITHIN THE BED AND PROVIDED WITH A NUMBER OF HOLES SO SIZED SUCH THAT THE QUENCH GAS LEAVES THE APPARATUS IN A UNIFORM MANNER. SUITABLE BAFFLE MEANS ARE PROVIDED IN COMMUNICATION WITH EACH HOLE TO BOTH PREVENT DIRECT HIGH VELOCITY IMPINGMENT OF THE QUENCH GAS ON THE BED AND TO ACHIEVE HIGHER PRESSURE DROPS SO THAT LARGER HOLES MAY BE USED, THEREBY REDUCING THE POSSIBILITY OF PLUGGING. IN A PREFERRED EMBODIMENT MEANS ARE ALSO PROVIDED FOR INSURING UNIFORMITY OF BED TEMPERATURE BY THE ELIMINATION OF LOCALIZED HOT SPOTS.
