Abstract: The present invention features a coke drum de-heading system that provides unique advantages over prior art de-heading systems, namely the de-heading of a coke drum without having to physically remove the head units. This is essentially accomplished using a specially designed dual seated, linear motion goggle blind gate valve, or de-header valve, that is removably coupled to and seals against the flanged portion of a coke drum much the same way a conventional head unit would be attached. The de-header valve is equipped with, among other things, a sliding blind that is contained and capable of moving within an upper and a lower seat, wherein one of such seats is a floating dynamic, live loaded seat that is capable of automatic adjustment through one or more loading zones so as to seal the blind between the upper and lower seats.

Abstract: An apparatus for processing an organohalogen compounds includes a catalyst container containing a catalyst layer, a supplying path for supplying a carrier gas containing organohalogen compounds and steam through the catalyst container, a cooling chamber arranged at a lower portion of the catalyst container, a spraying apparatus mounted in the cooling chamber for spraying a cooling liquid to cool exhaust gas containing a decomposed gas of the organohalogen compounds exhausted from the catalyst layer and a baffle member forming a bent path which introduces the exhaust gas containing the decomposed gas into the cooling chamber from the catalyst layer and mounted in the cooling chamber for preventing mists generated by spraying cooling liquid from the spraying apparatus from back flowing into the catalyst container.

Abstract: A process and method is provided for operating a small-scale high-throughput gasifier. As is known in the art, the exothermic combustion reactions can be separated from the endothermic gasification reactions. The exothermic combustion reactions can take place in or near the combustor while the endothermic gasification reactions take place in the gasifier. Heat from the exothermic zone is transferred to the endothermic reaction zone by circulation of an inert particulate solid such as sand. In order to increase efficiency by reducing heat loss from the gasifier, the gasifier is concentrically-disposed within the endothermic reaction zone of the combustor.

Abstract: Apparatus (10) for recovering fumes from a roofing kettle (12) includes a fan (72) for drawing air from the hollow interior of a housing (20). A conduit (34) extends through the housing front wall (22) and terminates in the hollow interior. A burner assembly (44) is disposed within the conduit (34) for providing a flame within the conduit (34). The housing side wall (30) includes a fresh air intake (78). A flexible metal hose (80) extends between the outer free end of the conduit (34) and the roofing kettle (12). Rotation of the fan (72) causes air to be drawn from the interior of the housing (20) and in turn through the fresh air intake (78), through the conduit (34) and the hose (80) from the interior of the kettle (12), and through the duct (46) and tube (58) of the burner assembly (44).

Abstract: A method and apparatus for treating wastes by two-stage gasification recovers metals or ash content in the wastes in such a state that they can be recycled, and gases containing carbon monoxide (CO) and hydrogen gas (H2) for use as synthesis gas for ammonia (NH3) or production of hydrogen gas. The wastes are gasified in a fluidized-bed reactor at a low temperature. Then, gaseous material and char produced in the fluidized-bed reactor are introduced into a high-temperature combustor, and gasified at a high temperature and ash content is converted into molten slag. After water scrubbing and a CO conversion reaction, the gas is separated into H2 and residual gas. The residual gas is then supplied to the fluidized-bed reactor as a fluidizing gas.
