Mechanical design of Process equipment
Mechanical design of Process equipment is a key subject for chemical engineers.
Here are some situations in which external pressure occurs relative to chemical engineering. We will discuss these situations and type of vessels. The first one is a vacuum vessel. This type of vessel purely designed for low internal pressure. The typical example is triple effective evaporators.
In the design of external pressure vessels, if the preliminary design calculations show that the calculated allowable pressure is less than the design pressure, operating pressure, then two options can be considered to proceed. The first option is to increase the shell thickness, but this may result in higher costs, weight, and machining costs. The second option is to add stiffening rings to the vessel, which will reduce the length of the shell and increase the allowable pressure. Stiffening rings, flanges, and other similar structures are treated as simply supported supports and divide the shell into segments with reduced length. Every segment behaves like a different shell and impacts the mathematical outcome of the equation. Stiffening rings can be placed internally or externally and various types of stiffening rings can be used in industrial fabrication. If the selected thickness is insufficient, the addition of stiffening rings to the vessel will divide the vessel into three sections, each section will be evaluated separately for the design pressure. By calculating l/d0 and d0/t and determining the factor A and B from charts, the overall allowable pressure can be increased
