An odd number of tube passes is seldom used except the 1-1 exchanger. A 1-2 shell-and-tube heat exchanger is illustrated in Figure 5.19. A shell and tube exchanger consists of a number of tubes mounted inside a cylindrical shell. Figure 1 illustrates a typical unit that may be found in a petrochemical plant. Two fluids can exchange heat, one fluid flows over the outside of the tubes while the second fluid flows through the tubes. A shell and tube heat exchanger is a class of heat exchanger designs. It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications.

[1] [2] It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. Design of shell and tube exchanger: A shell and tube heat exchanger is one of the most popular types of exchangers due to its flexibility. In this type, there are two fluids with different temperatures, one of them flow through tubes and another flow-through shell. Heat is transferred from one fluid to another through the tube walls, either from the tube side to the shell side or vice versa. Heat exchanger with removable bundle and floating tube-sheet suitable to compensate the different expansion of the tubes and the shell. The removable tube bundle allows easiness of cleaning also shell side.

As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. Shell and tube heat exchangers can be single-phase, or two-phase.

The Pharma-line shell and tube heat exchanger is designed to operate at pressures up to 10 bar and operating temperatures of 150°C. It is easy to drain and clean and features leakage detection. It is fully drainable on the product side, with no dead spots and has vent and drain possibilities on the utility side. The shell and tube heat exchanger is split into two main systems, referred to as the shell side and tube side.Each system has one associated flowing medium.
