Abstract A METHOD AND AN APPARATUS FOR QUENCHING HOT GASES OBTAINED IN TREATMENT OF HYDROCARBONS. A STREAM OF HOT GASEOUS HYDROCARBON ISSUES FROM A REACTOR AND IS CONVEYED IN A CONDUIT. IN THE IMMEDIATED VICINTY OF THE OUTLET CONNECTING THE REACTOR WITH THE CONDUIT THE LATTER IS PROVIDED WITH A LONG RADIUS BEND OF AT LEAST APPROXIMATELY 45* TO FACILITATE THE INJECTION OF COOLING LIQUID CONCURRENTLY AND COAXIALLY INTO THE STREAM OF HOT GASEOUS HYDROCARBONS WITHOUT OBSTRUCTION OF THE FLOW PATH FOR THE HOT GASEOUS HYDROCARBONS, IN ORDER TO AVOID ANY FLOW DISTRUBANCE OF THE STREAM OF HOT GASEOUS HYDROCARBONS PASSING THROUGH THE CONDUIT. DOWNSTREAM OF THIS BEND THE CONDUIT DIVERGES TO CONSTITUTE A DIFFUSOR. THE BEND IS ASSOCIATED WITH AT LEAST ONE FLUID-INJECTING NOZZLE WHICH INJECTS THE COOLING LIQUID, SUCH AS RECYCLED OR RECIRCULATED HYDROCARBONS, INTO THE OUTLET PORTION OF THE BEND.
