Ammonia Feed Line and Converter
As air and ammonia are fed to the reactor/converter, they must first be cleaned to prevent decomposition of the ammonia and contamination of the platinum gauze. FLEXIFIBER® mist eliminators are used to clean the air and ammonia before they are fed to the reactor/converter. This prevents decomposition of the ammonia and contamination of the platinum gauze. In addition, FLEXIFIBER mist eliminators are used to filter and recover any platinum carried off the gauze from the reactor.
After the process gas is condensed and the absorption takes place, the gas exiting the top of the absorber is referred to as tail gas. This tail gas can contain a large amount of entrained weak nitric acid mist. In addition to yield loss, this acid mist can corrode and shorten the service life of downstream equipment. DEMISTER® mist eliminators and FLEXIFIBER® mist eliminators have been used to remove entrainment in this application.
