  • Patent number: 11833448
    Abstract: A feedstock processing system extracts a product from a solid using a CTSE system comprising a plurality of continuous stirred tank extraction stages arranged in fluid communication with each other in series such that effluent from one stage flows to a next stage in the series. One of the stages has an inlet to allow a measured amount of liquid solvent and the solid to be introduced to the continuous stirred tank extraction stage. The stage mixes the solid with the introduced solvent to form a homogeneous slurry to enable the product associated with the solid to be extracted with the solvent. A solid-liquid separator is arranged in fluid communication with the continuous stirred tank extraction stages, and receives an effluent from one of the stages and separates the liquid solvent containing the product from the solid to form a product-containing liquid and a product-depleted solid.

  • Patent number: 11802101
    Abstract: Processes and systems for dehydrogenating ethylbenzene may include mixing a steam stream and an ethylbenzene stream to form a feed mixture. The ethylbenzene/steam feed mixture may then be fed to a dehydrogenation reactor containing an alkali metal promoted catalyst. A liquid, selected from an alkali metal liquid, an alkali metal compound liquid, or a liquid solution comprising an alkali metal, may be injected into a feed stream, such as the steam stream, the ethylbenzene stream, or the ethylbenzene/steam feed mixture. Following injection, the liquid vaporizes and disperses into the feed stream upstream of the dehydrogenation reactor. The liquid may be maintained as a liquid from a point upstream of injection to an injection nozzle. The liquid is dispersed through the injection nozzle, in liquid form, to form droplets of liquid dispersed in the feed stream, which evaporate and/or dissolve into the vaporous feed stream.

  • Patent number: 11786877
    Abstract: In the hydrochlorination reaction, silicon tetrachloride (STC), metallurgical silicon, and hydrogen are converted to trichlorosilane (TCS) at about 540° C. Previously, a pilot-scale reactor was used to study the yield of TCS produced by the hydrochlorination reaction. The yield observed by experimentation compared favorably with a scalable mathematical model developed to predict the rate of TCS conversion. The model predicted that 90% of the final amount of TCS produced was achieved after the reactant gas traveled a quarter of the vertical distance in the reaction section of the reactor. The pilot-scale reactor was shortened to verify the model predictions. In addition, some catalytic effects on the reaction were studied.
