ABSTRACT
Jacketing provides the optimum method of heating and cooling process vessels in terms of control, efficiency and product quality.
Using a jacket as a means of heat transfer offers many advantages:
All liquids can be used, as well as steam and other high-temperature vapors Circulation, temperature, and velocity of heat-transfer media can be accu-
rately controlled Jackets may often be fabricated from a much less expensive metal than the
vessel itself Contamination, cleaning, and maintenance problems are virtually elimi-
nated Maximum efficiency, economy, and flexibility is achieved
Alternatives to jacketing include electrical-resistance immersion heaters, external electrical heaters, and ind uction heating.
