    摘要: A tailings solvent recovery vessel substantially without conventional internals utilizes nozzles for forming very fine solvent-containing hydrocarbon droplets from a solvent-containing tailings feedstream. The hydrocarbon droplets are discrete from water droplets. The hydrocarbon droplets are small enough to result in a large surface area and a desired fall residence time but sufficiently large that they are not entrained with the rising vapor in the vessel. The feedstream is introduced to the vessel with a pressure drop to result in an initial flashing of the solvent from the solvent-containing droplets. Heat from the vessel atmosphere or from steam flowing countercurrent to the falling hydrocarbon droplets is transferred to the falling hydrocarbon droplets resulting in vaporization of any residual solvent therefrom. A substantially solvent-depleted pool is collected in the bottom of the vessel and retained only so long as is required to pump the underflow stream from the vessel.

    摘要: The present invention relates to the use of a (1→3)-β-D-glucan as an emulsion stabilizer. The present invention further relates to emulsions comprising a (1→3)-β-D-glucan in an amount of 0.01 to 10 wt. %, based on the total weight of the emulsion. The present invention also relates to bitumen binder compositions comprising a (1→3)-β-D-glucan in an amount of 0.005 to less than 0.1 wt. %, based on the total weight of the bitumen binder composition. The present invention further relates to emulsions comprising a novel biodegradable emulsifying agent, in particular in combination with a (1→3)-β-D-glucan.

    摘要: A method and system are disclosed for treating the effluent from a hydrocarbon pyrolysis unit employing a small primary fractionator. The method comprises cooling the effluent from a furnace through a first heat exchanger, a vapor-liquid separator, and a second heat exchanger before it is passed to a fractionator for further processing. These heat exchangers may also be utilized to heat a utility fluid as part of the cooling process. Further, one or more generators and a third heat exchanger may also be used to assist in heat recovery for the process.

    摘要: A system, apparatus and method for hydrocarbon extraction from feedstock material that is or includes organic material, such as oil shale, coal, lignite, tar sands, animal waste and biomass. A retort system including at least one retort vessel may include a monolithic dome structure surrounded by a process isolation barrier, the dome structure being sealingly engaged with the process isolation barrier. The dome structure and the process isolation barrier define a retort chamber, at least a portion of which may comprise a subterranean chamber. A lower end of the dome retort structure provides an exit for collected hydrocarbons and spent feedstock material. Systems may include a plurality of such dome retort structures. A control system may be used for controlling one or more operating parameters of a retorting process performed within such a dome retort structure for extraction and collection of hydrocarbons.
