  • Convective thermal removal of gaseous inclusions from viscous liquids
    Patent number: 10173915
    Abstract: A method for removing gaseous inclusions from a viscous liquid in which a viscous liquid stream having gaseous inclusions is introduced into a refining chamber, resulting in a flowing viscous liquid layer. The viscosity of a bottom portion of the viscous liquid layer is reduced in a first refining zone in the refining chamber so as to produce an upwardly mobile reduced viscosity portion of the viscous liquid layer. Heat is introduced into the viscous liquid layer from above the viscous liquid layer in a second refining zone in the refining chamber downstream of the first refining zone, reducing the gaseous inclusions in said viscous liquid layer. Thereafter, the viscous liquid layer having substantially reduced gaseous inclusions is discharged from the refining chamber.
