  • Drying a coating using electromagnetic radiation or heating of drum
    Patent number: 11492300
    Abstract: Methods, systems, and apparatuses for coating a material by contacting the material with a coating material and a solvent are disclosed herein. The coated material can be obtained by evaporating the solvent: by heating the coated material directly or indirectly with electromagnetic radiation; by heating with heat generated from a heat source that heats an internal container for the material to be coated and/or coated material; and/or in an interior volume of a coating container having a side wall, by heating a portion of the side wall of the coating container and/or internal container with a heat source that is positioned outside of the interior volume of the coating container.
    Type: Grant

  • Solvent recovery from sweep gas streams
    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.

  • Selective olefin oligomerization
    Patent number: 6376731
    Abstract: A process is provided for the production of a gasoline blending fraction rich in isooctane by the dimerization of isobutylene using tertiary butyl alcohol modifier and lower alkane diluent; advantageously the isobutylene is derived from the dehydration of tertiary butyl alcohol.

  • Isobutylene oligomerization using isooctane diluent
    Patent number: 5877372
    Abstract: A process is provided for the production of a gasoline blending fraction rich in isooctane by the dimerization of isobutylene using tertiary butyl alcohol modifier and isoalkane diluent; advantageously the isobutylene is derived from the dehydration of tertiary butyl alcohol and the isoalkane used as diluent in the dimerization is the product formed by hydrogenation of the oligomerization product.
