    摘要: A spin pack for spinning multiple components includes a distribution device which distributes mutually separated molten polymer streams to a spinneret so that each mutually separated molten polymer stream is accessible at each active spinneret backhole. Intermediate the spinneret and the distribution device, a selection assembly selects which, if any, mutually separated molten polymer stream flows into which backhole.

    摘要: Oxidation of an alkane to an alkanone in a process stream forms aldehyde-based impurities. A method of minimizing the aldehyde-based impurities introduces an amine into the process stream to minimize the aldehyde-based impurities. The amine interacts with the alkanone and the aldehyde-based impurities thereby forming heavy products. The method separates the heavy products from the alkanones to reduce a level of the aldehyde-based impurities. The process stream preferably includes cyclohexyl ketone as the alkanone and n-hexanal as the aldehyde-based impurity. The method is typically involved in synthesis of a caprolactam.

    摘要: An apparatus for treating a plurality of particles, such as ammonium sulfate, with a coating, such as a wax, to prevent caking of the particles. The apparatus includes a feed chute, a diffuser and an exit chute. An applicator is mounted adjacent a base of the diffuser for spraying the coating downwardly away from the diffuser into a predefined pattern. The exit chute includes a deflector for intersecting a curtain of particles falling from the diffuser and for redirecting the particles into the predefined pattern of the coating. A heating element is mounted to the deflector for maintaining a predetermined temperature of the deflector thereby preventing accumulation of the coating on the deflector.
