Abstract: A process for producing a partially balanced acid solution that involves metering dicarboxylic acid powder, based on weight, from a loss-in-weight feeder to a feeding conduit that transfers the dicarboxylic acid powder at a low variability feed rate into an in-line disperser, adding a first feed stream of diamine to the in-line disperser in an amount sufficient to form the partially balanced acid solution having a solids content of less than 60%, and storing the partially balanced acid solution at a temperature to maintain the dissolved dicarboxylic acid and to prevent formation of a slurry. The partially balanced acid solution may be used as a feed solution to prepare a nylon salt solution. Process controls for the process are also disclosed.

Abstract: A continuous process for producing a nylon salt solution prepared using a liquid partially balanced acid solution enriched in dicarboxylic acid, and in particular adipic acid. The liquid feed is prepared by metering dicarboxylic acid powder, based on weight, from a loss-in-weight feeder to a feeding conduit that transfers the dicarboxylic acid powder into an in-line disperser; feeding a first feed stream of diamine to the in-line disperser to form a dispersion comprising between 32 wt.% and 46 wt.% dicarboxylic acid, between 11 wt.% and 15 wt.% diamine, and between 39 wt.% and 57 wt.% water, and heating the dispersion at temperature between 50C and 60C to form a partially balanced acid solution. A nylon salt solution is prepared from the liquid partially balanced acid solution and continuously withdrawn into a storage tank. The nylon salt solution has a uniform pH and is suitable for producing nylon polymers.

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.

Abstract: The present invention relates to a system and a process for producing hydrogen cyanide and more particularly, to a process for controlling operational stability of the system and process by blanketing the system with inert gas. More particularly, the present invention relates to the flushing of the system with an inert gas when a crude hydrogen cyanide product exceeds a threshold of oxygen, such as greater than 0.4 vol.% oxygen.
