Abstract
A method and apparatus for steam cracking hydrocarbons in a furnace (10) having rectilinear single-pass tubes (12) which are interconnected at their outlet ends by a manifold (18) within which the steam cracking effluents are subjected to limited pre-quenching by injection of a cooler gaseous medium, with the effluents then being conveyed to quenching means (22). The invention serves in particular to increase the yield of hydrocarbon steam cracking installations.
