Abstract: A process for the thermal treatment of incombustible liquids in a combustion space of a combustion apparatus by contacting the incombustible liquid with a supplementary fuel in the combustion space in the presence of at least one reactive gas. The process of the invention comprises feeding the incombustible liquid and the supplementary fuel into the combustion space (1) at different points, mixing the incombustible liquid with at least one reactive gas and the supplementary fuel with at least one inert gas prior to the contacting, and vaporizing the incombustible liquid and supplementary fuel prior to the contacting in the combustion space.

Abstract: Polymeric compositions include a nonaqueous additive system having dispersant-coated pigments physically dispersed in a liquid nonaqueous polymeric carrier which may be added directly to a melt flow of a polymeric host material. The additive system employed in the polymeric systems is most preferably in the form of a particulate paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being spun into filaments. By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more into the melt flow of host polymeric material, shaped objects of the polymeric material (e.g., melt-spun filaments) having different additive attributes may be produced on a continuous basis without shutting down the shaping operation.
