    Abstract: Processes and systems for the production of hydrogen cyanide via the Andrussow process are described. A reaction zone, wherein oxygen, ammonia, and methane can be allowed to react in the presence of a catalyst comprising platinum to provide hydrogen cyanide. A desulfurization zone, wherein a feed stream comprising sulfur and at least one of the oxygen, the ammonia, and the methane can be contacted with a desulfurization material to produce a sulfur-reduced feed stream that is provided to the reaction zone. In an example, the desulfurization material includes zinc oxide.

    Abstract: An elastic thread transporting assembly and method provides for the transporting of thread to a production line. The assembly includes a thread creel for supplying multiple threads. The thread creel defines an unwinding location. A carrier is positioned for transporting the threads to the production line along a carrier path. An attachment device for attaching the threads to the carrier is provided. The attachment device is placed in close proximity to the unwinding location. The carrier path provides unrestricted access to the threads between the unwinding location and the production line.
