    Abstract: Methods, systems, and apparatuses for coating a fertilizer material by contacting the material with a coating material and a solvent are disclosed herein. The coated material can be obtained by mechanically agitating the fertilizer material while contacting the fertilizer material with a coating material and a solvent. The coating material can be sprayed onto the fertilizer material during mechanical agitation. The coating process and apparatus can use a paddle mixer and can be configured to handle organic solvents used to carry the coating material.

    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.
