What are Pressure Vessels?

A pressure vessel is a closed container that is supposed to be leak-proof and is often cylindrical or spherical. Its purpose is to keep fluids (such as gases or liquids) at a pressure that is significantly different (higher or lower) than the pressure of the surrounding environment. They are often composed of carbon or stainless steel, and the welding process is used to build them from plate components. However, in some contexts, materials besides metals and non-metals, such as aluminium, copper, and other non-metals, are also used to construct pressure vessels. Even though most pressure vessels take the form of a long cylinder with two heads at each end, these containers can also be shaped like a sphere or cone.

Columns, boilers, separators, knock-out drums, towers, bullet tanks, reactors, and heat exchangers all refer to types of pressure vessels used often. All of these pressure vessels see heavy usage in the oil and gas industry, as well as in refining petroleum and processing chemical and petrochemical products. Power plants experience various operating pressures and temperatures in their facilities. Be aware that a tank that stores things at atmospheric pressure is not a pressure vessel.

Different Types of Pressure Vessels Intended for Various Applications

Storage Vessels

Storage vessels are pressure containers that are used to keep liquids, vapours, and gases for a temporary period. The container may be used later in a subsequent process to hold fluids, or it may be used to store completed goods like compressed natural gas (CNG) and liquid nitrogen.

Heat Exchangers

Heat exchangers transfer heat from one fluid to another or between many fluids. They find widespread application in the food processing, pharmaceutical, energy, and bioprocessing sectors. The functionality of heat exchanger equipment is reliant on the thermal and flow characteristics of the fluids participating in the heat exchange and the thermal property of the conductive partition (for indirect contact heat exchangers). The difference in temperature between the hot and cold fluids in a heat exchanger causes the materials in the device to be subjected to stress, as does the internal pressure of the device, which contains the fluids.

Boilers

A boiler is a piece of heat transfer equipment that can draw its heat from a fuel, nuclear, or electrical power source. In most cases, they form an enclosed vessel that acts as a conduit for transferring heat from the heat source to the fluid being heated. The primary purpose of these devices is to heat liquids. Inside the boiler, a phase change from the fluid being in the liquid state to the fluid being in the vapour state will frequently occur. The vapour produced by the boiler is put to use in various heating applications as well as the production of electricity. Steam boilers produce steam at a higher pressure than normal, which is then used to speed up the turbine blades. As a result, the vessel that constitutes the boiler needs to have a high level of strength to withstand such high pressures and levels of thermal stress. When the temperature increases, most materials see a reduction in their level of strength.

Pressure Vessels

The term "pressure vessels" refers to a large category of vessels called "process vessels." These vessels are utilised throughout the manufacturing process for mixing and agitation, decantation, distillation and mass separation, and chemical reaction. The type of the process being carried out and the transformation of the substances being dealt with both have a role in the change that occurs in the internal pressure of the process vessel.
