  • Patent number: 11291944
    Abstract: A method for removing solvent from a solvent containing sweep gas stream obtained from a fertilizer coating process is disclosed. The method can include directly contacting the solvent containing sweep gas stream with an aqueous composition comprising 50% wt/wt to 100% wt/wt of water, condensing at least a portion of the solvent out of the solvent containing sweep gas stream into the aqueous composition to produce a solvent-enriched aqueous composition and a recovered sweep gas stream, and removing the recovered sweep gas stream from the solvent-enriched aqueous composition.

  • Publication number: 20100132257
    Abstract: Systems and methods for processing carbonaceous material are provided. In one or more embodiments, a carbonaceous material and water can be mixed to provide a slurried mixture. The water mixed with the carbonaceous material can be at least 90% liquid phase. At least a portion of the slurried mixture can be gasified in the presence of a combustion gas to provide carbonaceous solids and a syngas comprising hydrogen, carbon monoxide, and carbon dioxide. The syngas can be at a temperature of from about 400° C. to about 1,650° C. At least a portion of the carbonaceous solids can be selectively separated from the syngas to provide a syngas product and carbonaceous solids. At least a portion of the separated carbonaceous solids can be combusted in the presence of an oxidant to provide at least a portion of the combustion gas.
