    摘要： An apparatus for vaporizing volatile liquids comprises a packed column, a gas inlet port (for introducing a hot entrainer gas), a feed tube (for introducing a volatile liquid), a feed distributor comprising a base plate equipped with orifices (through which the liquid flows downward into the packed column) and risers (through which the formed gaseous mixture of entrainer gas and vaporized liquid flows upward), and a gas outlet port. This apparatus can be used to vaporize volatile liquids, preferably volatile tin compounds, optionally in admixture with volatile silicon compounds, wherein steam is used as the entrainer gas.

    摘要： A liquid tin-containing antifoulant composition is injected into a metal-walled thermal cracking reactor tube, concurrently with the injection of a gaseous stream (preferably a steam-diluted C.sub.2 -C.sub.4 alkane stream), through a nozzle of an injection quill which is positioned in the center region of the reactor tube substantially parallel to the flow of the gaseous stream.A liquid tin-containing antifoulant is injected into a metal-walled thermal cracking reactor tube through a nozzle of an injection quill at a temperature of about 1000.degree.-1300.degree. F. while a gaseous stream (preferably a steam-diluted C.sub.2 -C.sub.4 alkane stream) flows through the reactor tube, followed by raising the temperature to about 1400.degree.-1800.degree. F. Preferably, the metal walls of the reactor tube are treated with steam after the antifoulant injection at about 1000.degree.-1300.degree. F. but before the antifoulant injection at about 1400.degree.-1800.degree. F.
