摘要： Combustion gas such as air, oxygen-enriched air or oxygen is introduced to a calcining zone at an intermediate level in a vertical shaft kiln for the calcining of petroleum coke utilizing a plurality of radially disposed combustion gas injectors and at least one vertically disposed injector located within the shaft kiln and extending into the calcining zone. The injector includes means for circulating coolant around the periphery of the injector so that common metals may be used in the high temperature (above 2000.degree. F.) environment of the shaft kiln. The vertical combustion gas injector may extend from the top of the calcining chamber to the calcining zone or from the bottom of the calcining chamber to the calcining zone. When the vertical combustion gas injector extends vertically upwardly from the bottom of the calcining chamber, means for introducing recycle gas to the calcining chamber may be incorporated into the vertical combustion gas injector.

摘要： A vertically disposed gas distributor for injection of combustion air into a shaft kiln. The air distributor extends from the upper portion of the shaft kiln to an intermediate combustion zone, and includes at least one cooling water inlet line and at least one cooling water return line. The cooling water inlet and return lines extend along and adjacent to the outer surface of a central gas conduit. The distributor includes an insulation layer covering the central gas conduit and the cooling water inlet and return lines, and includes a baffle member which directs cooling water from the cooling water inlet line around the outlet end of the gas conduit and to the cooling water return line.

摘要： A slide valve for use in a high temperature gas line is described. The valve is constructed to allow field assembly and disassembly for ease of service, and has insulating means and gas purge means for maintaining the exterior of the valve housing at a low temperature. The valve includes a slide plate which can be provided with a flow opening in either a first location such that the slide plate is in tension when the valve is closed while hot or in a second location such that the slide plate is in tension when the valve is opened while hot.

摘要： An internal draw tray is added to the flash zone of a coker fractionator below the coker vapor inlet to collect condensed coke drum overhead components and to keep the condensed material separate from the fresh feed to the coker furnace.

摘要： A delayed coking process in which the coker furnace feed is free of conventional heavy recycle. Elimination of this material from the coker furnace feed produces, based on fresh feed to the process, increased liquids and decreased coke. Coker furnace feed is initially combined with a diluent hydrocarbon having a lower boiling range than conventional heavy coker recycle and then transferred to the coker furnace. The hydrocarbon diluent is much lower in coke-forming components than the heavy recycle which is normally combined with the fresh feed and fed to the coker furnace.
摘要翻译： 延迟焦化方法，其中焦化炉进料不含常规重循环。 根据该方法的新鲜进料，从焦化炉进料中除去该物质会增加液体和减少焦炭。 起始炉料进料最初与沸点比常规重焦化循环再沸的稀释烃组合，然后转移到焦化炉中。 碳氢化合物稀释剂比通常与新鲜进料组合并进料到焦化炉中的重质循环物相比低得多。
