Effect of Mechanical Design – UA

The product of the overall heat transfer coefficient and area (UA) determines the controllability of temperature processes. The deterioration of the UA is a particular concern for crystallization and polymerization processes. Frosting and fouling can decrease process efficiency and production rate even if the controllers are retuned. For exothermic reactors, a decrease in the UA …

Identifying Equipment Performance Problems

Plants often consist of many production units and trains of equipment. The production units may produce raw materials as intermediates in a series of processes that lead to predominant product. Often intermediates or byproducts are also sold. Trains of equipment feed into a common tank that may feed other trains of equipment. Recycle streams further …
