ABSTRACT:
An apparatus for quenching pyrolysis gas, in which cooling of pyrolysis gas of hydrocarbons can be carried out very rapidly, decoking of pyrolysis furnace can be carried out easily and the life of apparatus can be extremely extended, is provided according to the apparatus in which the upper outlet of each of cracking tubes of a multi-tubular pyrolysis furnace for hydrocarbons is connected directly with each of vertical introducing pipes for pyrolysis gas, having a diameter larger than that of said upper outlet, and situated on a level upper than that of said upper outlet; cooling pipes for pyrolysis gas having closed lower ends are inserted in said introducing pipes in the same direction therewith; pipes for flowing-in a cooling medium, the lower ends of which pipes open into said cooling pipes at the position close to the closed ends of the cooling pipes are provided and opening parts for each of fluids are provided in the neighborhood of the upper ends of said introducing pipes and said cooling pipes, respectively.
