| 208132000 | With heating in tubular confined stream | 7 |
| 20080302702 | Hydrocarbon thermal cracking using hardfaced fittings - A thermal cracking process that employs (1) a sinusoidal conduit in the convection section of a thermal cracking furnace, (2) a cross-over conduit, and/or (3) a transfer conduit that contains at least one bend fitting, at least one bend fitting carrying a protective layer comprising a steel carrier and carbide pellets composed of submicron hard particles cemented with a metal binder. | 12-11-2008 |
| 20090057200 | Production of an upgraded stream from steam cracker tar by ultrafiltration - This invention relates to a process of producing an upgraded product stream from steam cracker tar feedstream suitable for use in refinery or chemical plant processes or for utilization in fuel oil sales or blending. This process utilizes an ultrafiltration process for separating the steam cracker tar constituents resulting in a high recovery, low-energy process with improved separation and product properties. | 03-05-2009 |
| 20090107888 | Tube handling method and apparatus - An apparatus and method for both removing and installing an elongate member at an elevated location on a piece of equipment. The apparatus includes a cantilivered elongate bed having a lattice work support system that carries a motor driven cable draw works, a portion of the lattice work being removable. One method involves using the apparatus to remove a tube from a pyrolysis furnace. Another method involves using the apparatus to install a tube in a pyrolysis furnace. | 04-30-2009 |
| 20090250378 | CONTINUOUS STEAM PYROLYSIS METHOD - A continuous steam pyrolysis method is provided. The method comprises feeding a material to be pyrolyzed into a tubular reactor and carrying out a pyrolysis reaction in the tubular reactor in the presence of a superheated steam flow. The material to be pyrolyzed passes through one or more proceeding zones and one or more blending zones during the pyrolysis reaction in the tubular reactor. The total length of the one or more blending zones ranges about 5% to about 35% of the total length of the proceeding zones and the blending zones. | 10-08-2009 |
| 20100133146 | Coil for pyrolysis heater and method of cracking - Randomly packing with filler material at least part of a pass in a coil used in a system for pyrolyzing hydrocarbon feedstock to lighter hydrocarbons. Randomly packing increases heat transfer and decreases the rate of coke build-up within the coil, yielding an improvement in overall system efficiency. Packing material can comprise or be treated with a suitable catalyst for increasing the rate of chemical decomposition, thus further improving system efficiency. | 06-03-2010 |
| 20140174986 | ELECTRICAL INDUCTION HEATING ASSEMBLY - The invention discloses an electrical induction heating assembly which comprises an induction heating coil surrounding and being thermally insulated from a concentric closed cylindrical chamber having an inlet and an outlet. An electrically conductive element is located within or forms part of the chamber. The chamber includes means for uniform distribution of material that is to be heated in the chamber. A body of discreet agitating media is contained within the chamber. The body of discreet agitating media typically comprise steel balls. | 06-26-2014 |
| 20140238899 | System and Method for Controlling and Optimizing the Hydrothermal Upgrading of Heavy Crude Oil and Bitumen - A system and method is provided for upgrading a continuously flowing process stream including heavy crude oil (HCO). A reactor receives the process stream in combination with water, at an inlet temperature within a range of about 60° C. to about 200° C. The reactor includes one or more process flow tubes having a combined length of about 30 times their aggregated transverse cross-sectional dimension, and progressively heats the process stream to an outlet temperature T(max)1 within a range of between about 260° C. to about 400° C. The reactor maintains the process stream at a pressure sufficient to ensure that it remains a single phase at T(max)1. A controller selectively adjusts the rate of flow of the process stream through the reactor to maintain a total residence time of greater than about 1 minute and less than about 25 minutes. | 08-28-2014 |
