While one would hope that the natural ingenuity and problem-solving skills of mechanically-minded maintenance teams would know all the tricks of the trade to keep a chemical plant functioning optimally, this should not be taken for granted. In every industry, professionals must continue to learn and grow in their skills while staying abreast of technologies that can improve routine maintenance. One of these areas is corrosion protection, which can have a significant impact on the longevity of process heating and cooling equipment and whether or not unwelcome corrosion-related interruptions occur. Awareness of the proper tools for prevention can make a significant difference.

Fouling occurs when unwanted substances accumulate on heat-transfer surfaces, reducing the efficiency of the ammonia recovery process. Effective fouling-control strategies are therefore essential to ensure efficient and sustainable ammonia recovery operations. Common fouling-control strategies include chemical cleaning, mechanical cleaning and filtration. Implementing these strategies early in the design process is important to minimize fouling and maximize ammonia recovery efficiency. Furthermore, an understanding of the different equipment and process-technology configurations during the early design stage can help to reduce the risks for fouling. This article examines various ammonia recovery technologies and discusses design considerations related to fouling.
