Design of the electrical reticulation and instrumentation for heating, using ceramic as well as pyro elements. A powder needed to be heated and trace heating of the transfer line in order for the powder to be pumped into a catalyst filled reactor at a positive pressure. Ammonia was also fed through the catalyst reactor at a specified flow rate in order for the reaction to take place, the dual-Thompson effect came into play when feed rates were set too high initially, which freezes the line at a restriction. Eventually flow rates pressures, catalyst regeneration etc were fine tuned and the plant produced efficiently. Temperatures ranged from 450 deg C upwards to enable catalyst reactors to function properly. Heater controllers with Zero crossover switching were used and the area was classified as a Hazardous area. Because Ammonia has such a strong odor an ammonia recovery column was installed with strict monitoring of flow rates and concentration of aqueous ammonia. Products were being developed and therefore the plant had to remain flexible to allow for major control changes. A Broadbent centrifuge also had to be upgraded, tested and setup for the recovery of the white end product CyanoPhenol.
