Abstract: A system for removing salt from a process stream being fed into a flash separator introduces a swirling motive fluid into the fluid column of the separator. The swirling motive fluid comes into contact with salt components residing in the fluid of the column to create a salt slurry. Means to limit the upward movement of the swirling motive fluid can be provided. The salt slurry is then removed and can be sent to a brine generation vessel. Saturated brine from the vessel is transported back to the fluid column to replace the motive fluid in the column.
Abstract: In the production of fuel such as ethanol from carbonaceous feed material such as biomass, a stream comprising hydrogen and carbon monoxide is added to the raw gas stream derived from the feed material, and the resulting combined stream is converted into fuel and a gaseous byproduct such as by a Fischer-Tropsch reaction. The gaseous byproduct may be utilized in the formation of the aforementioned stream comprising hydrogen and carbon monoxide.
