Abstract
A method of injecting a liquid tin-containing antifoulant into a saturated hydrocarbon feed stream for a thermal cracking reactor comprises providing a first open-ended tube, a second open-ended tube which concentrically surrounds the first tube, and a third tube which concentrically surrounds the first and second tubes; passing a liquid antifoulant stream through the first tube, a dispersing gas stream through the second tube, and a hydrocarbon gas stream (preferably containing ethane and steam) through the third tube; injecting the liquid antifoulant through the open end of the first tube and the dispersing gas through the open end of the second tube into the hydrocarbon gas stream; and passing the mixture of dispersed antifoulant, dispersing gas and hydrocarbon gas into a thermal cracking reactor.
