For our Bendel chemical engineering customers, a jacketed vessel is a container that is designed for controlling the temperature of its contents, by using a cooling or heating “jacket” around the vessel through which a cooling or heating fluid is circulated.
A jacket is a cavity external to the vessel that permits the uniform exchange of heat between the fluid circulating in it and the walls of the vessel. There are several types of jackets, depending on the design.
Conventional Jackets provide a large heating or cooling transfer area however, depending upon the pressure, can be substantially more expensive than other alternatives.
Half Pipe Jackets are more expensive than dimpled jackets but do not have the pressure or cycling limitations of dimpled jackets. All three external jacket options do not pose a potential for material contamination.
Dimpled Jackets also provide for a large heating or cooling transfer area but are not recommended for pressures exceeding 200 psi or when the cycling of steam and cooling water is to be utilized in the process. The cost of dimpled jackets is relatively inexpensive.
Internal Coils provide for good heating and cooling surface contact while handling high internal and external pressures. If the stored material is not corrosive to the coil then this may be the most economical option. However, internal coils do not offer the degree of safety from contamination by the heating or cooling medium that external jackets can provide.
Jacketed vessels can be employed as chemical reactors (to remove the elevated heat of reaction) or to reduce the viscosity of high viscous fluids (such as tar).
