High temperature liquid injection apparatus |
摘要 |
A feed line to a pyrolysis furnace and a liquid injection apparatus for introducing a liquid coke inhibitor in the feed line are disclosed. The injection apparatus includes a central passageway for supplying the liquid coke inhibitor, an annular passageway for delivering an atomizing gas and a mixing reservoir for mixing the liquid and gas wherein the mixed fluid is atomized by passage through an orifice in a nozzle. A cooling jacket surrounding the annular passageway prevents decomposition of the coke inhibiting agent which products can plug the nozzle. The injection apparatus is typically installed in a bend of a process feedstock conduit with a discharge end aligned to an axis of the flow. A hot injection point close to the inlet of the pyrolysis furnace is preferred for best results. To help ensure complete evaporation of a carrier liquid prior to the furnace, the injection apparatus can include an evaporation shroud. For a modularized injection system, the evaporation shroud can include a larger diameter bonnet exterior to the conduit having the injection apparatus attached thereto. For a retractable injection system, the injection apparatus is received within an isolation valve having an outlet end stuffing box.
