A method which reduces iron contamination of a system which receives ammonia from an ammonia recovery process by one or more of the following techniques:a) Physically separating iron oxide, iron containing colloidal particles, and liquid droplets from the gas stream;b) Preventing AC from depositing on piping via elimination of condensation, thereby preventing corrosion of the piping; orc) Installing piping and equipment that is not susceptible to corrosive attack by AC, thereby eliminating the source of iron contamination.
