1. Definition of Pressure Vessel

- A pressure vessel is a closed container designed to hold gases or liquids at a pressure different from the ambient pressure.

- The pressure differential is potentially dangerous and many fatal accidents have occurred in the history of its development and operation.

- Consequently, its design, fabrication, and operation are regulated by engineering authorities backed up by laws. For these reasons, the definition of a pressure vessel varies from country to country, but it involves parameters such as the maximum safe operating pressure and temperature.

2. General Design

- MAWP: The maximum allowable working pressure (MAWP) is the maximum permissible gauge pressure in the pressure vessel. It is determined as the lowest MAWP of all the vessel's components based on their actual supplied thicknesses.

- MDMT: The minimum design metal temperature (MDMT) is the lowest temperature at which the component is designed to have adequate fracture toughness. It is a function of the component’s material specification and thickness.

3. Designing Vessel Support

1) Seismic Design

Earthquake can cause large scale destruction of industrial structures and equipment. To minimize this, the loading generated by the earthquake should be properly taken into account at the design stage.



2) Wind Design

A wind load differs from a seismic load in that it is more orless constant; whereas, the seismic load lasts a relatively short duration.In addition, the wind pressure varies at different heights of thevessel. A vessel must be designed for the worst case of windor seismic loads, but it is not designed for the case where both maximum loads are applied simultaneously.
