Heat-Balance Calculations
If you have read this far, and understood what you have read, you will readily understand the following calculation. It is simply a repetition, with numbers, of the discussion previously…
Kettle Type Reboiler
Kettle reboilers are commonly applied when a wide range of process operations (high turndown capability), large heat exchange surface, or high vapor quality is required.Kettle reboiler is also called a…
Types of Reboilers
Reboilers are classified according to their orientation and the type of circulation employed. The most commonly used types are described below. A. Kettle Reboiler Kettle reboilers are commonly applied when…
Reboiler Theory
The transfer of heat to and from process fluids is an essential part of most chemical processes. A reboiler is a heat exchanger that is used to generate the vapor supplied to…
Equipment Design in Advantages and Disadvantages
Advantages · Lower condensing pressures than air cooled condensers. · Better control over condensing pressure. · Since water has excellent heat transfer characteristics, water cooled condensers are more compact than air cooled condensers.…
Equipment Design
The water cooled chillers shown below use an evaporator to remove heat from the process and then use a water cooled condenser to remove the heat from the evaporator. Water…
Evaporative
General Information/Equipment Design Evaporative condensers are used when the water supply is insufficient to operate a water cooled condenser, or when the condensing temperature is lower than air cooled condensers…
Water Cooled
This section discusses water cooled condensers, such as the one shown here. General Information In most water cooled condensers, the water runs through tubing or coils in a sealed shell.…
Advantages and Disadvantages of Condensers
Advantages · Easy to install. · Requires no water. · Condensing medium, air, will not freeze. Disadvantages · As water condenses, it has the risk of freezing at low operating temperatures. · Adequate supply of…
Equipment Design
The hot vapor to be condensed travels through a series of finned copper tubes. Fans force air to circulate around the tubes, and this air removes heat from the vapor.…
