Description:
The report gives results of an examination of contaminant content and selected treatment techniques for process condensate from seven different ammonia plants. Field tests were performed and data collected on an in-plant steam stripping column with vapor injection into the reformer furnace stack. Bench scale steam stripping was studied on several different plant process condensates for comparative purposes. Data for design of a commercial steam stripper were obtained on the bench scale unit. Design conditions for the commercial unit were given. Four different methods of treating the stripper overhead were compared. The results indicate that stripping the process condensate and injecting the vapor into the reformer stack offers a viable control technology for reducing the amount of ammonia and methanol discharged to the environment.
