Design guidelines outline solutions for reducing fouling in distillation columns

DISTILLATION—1When designing mass transfer equipment for fouling service, one must first understand the fouling mechanism, the process in which the fouling occurs, and the process' behavior when the fouling occurs.Fouling in distillation columns can lead to:Greater energy consumption due to heat transfer and efficiency problems.Reduced column capacity, which may lead to production losses.Increased down time to clean the tower and dispose of fouling materials.Potential need for chemical additives.There are many different opinions of how to design tower internals for fouling services. Because distillation is part art and part science, different designs can work in the field.Trays ...
