    摘要： A method of steam cracking using a steam cracking arrangement including an electric cracking furnace without a convection zone and a quench cooling train is proposed, wherein a process gas stream is passed through the cracking furnace and the cooling train. The cooling train is operated to comprise at least two distinct cooling steps arranged in either order, wherein in a first cooling step at least a part of the process gas stream withdrawn from the electric cracking furnace is cooled against vaporizing boiler feed water at an absolute pressure level between 30 and 175 bar and wherein in a second cooling step at least a part of the process gas stream withdrawn from the electric cracking furnace is cooled against a superheated mixture of feed hydrocarbons and process steam used in forming the process gas stream which is thereby heated to a temperature level between 350 and 750° C.

    摘要： A hybrid steam cracking process including, in addition to combusting a fuel in a steam cracker furnace to provide thermal energy to the radiant and convection sections, heating a segment of an external furnace piping using an electrical heating device. The external furnace piping can include, e.g., the hydrocarbon-containing feed inlet piping, the cross-over piping, the radiant section inlet piping, and the radiant section outlet piping. Capacity and selectivity of the steam cracker furnace can be enhanced compared to conventional steam cracking process without electrical heating. The technology can be conveniently deployed in existing conventional steam cracking facilities.

    摘要： A process for catalytic reaction of heavy oils and a particulate solid medium, which comprises withdrawing a part or the whole of the used medium from the reactor, separating the withdrawn particles into the particles which have been rendered magnetic by the deposition thereon of nickel, vanadium, iron and copper originally contained in the heavy oils, and non-magnetic particles, using a high gradient magnetic separator which is so designed that a ferromagnetic matrix is placed in a uniform high magnetic field, and returning the non-magnetic particles of the medium into the reactor for re-use.
