Abstract (en)
[origin: WO2015200022A1] A process and system are provided for controlling an amount of ammonia and/or air provided to an ammoxidation reactor. The process includes maintaining a pH of a quench water bottoms and adjusting an amount of ammonia in a reactor feed to provide an ammonia to hydrocarbon ratio of about 1 to about 2 in the reactor feed. Further, the process may include adjusting an amount of air the reactor feed to provide an air to hydrocarbon ratio of about 9 to about 10 in the reactor feed.
