shell and tube heat exchanger symbol

The hot process stream leaves the HEx Condenser as a cool, condensed liquid and the air leaves warmer. This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it.

The timestamp is only as accurate as the clock in the camera, and it may be completely wrong. The liquid flows over the weir and leaves through the product outlet, most likely heading to cooling via further heat exchange in more HExes, and finally to storage in the Tank Farm. Various arrangements of convex and concave corrugated tubes were investigated.

("I Put a Spell on You," Screamin' Jay Hawkins, 1956), No hocus-pocus about it, a "shell and tube heat exchanger" is often referred to as a "HEx.". If both tube and shell are corrugated, the exergy loss and NTU increase about 17–81% and 34–60% respectively. Ye Old Familiar 2 Pass-Tubeside (U-Tube) HEx.

The symbol labelled "U-Tube Heat Exchanger" is the familiar 2-pass tube side type HEx that PTOA Readers and Students have already studied extensively and which is once again shown below. Weirs are little dams used in process industry to manage liquid levels and flows. Reboilers are a type of HEx used to return hot vapors into the bottom of a tower and separate hot liquid product from the vapor. This document specifies requirements and gives recommendations for the mechanical design, material selection, fabrication, inspection, testing and preparation for shipment of shell-and-tube heat exchangers for the petroleum, petrochemical and natural gas industries. Dimensions and Weights (full) ASME B36.10 Pipes (11 pages) NPS 1/8 - NPS 80 Corrugated tubes were produced by means of a special machine which was developed for this purpose. This document specifies requirements and gives recommendations for the mechanical design, material selection, fabrication, inspection, testing and preparation for shipment of shell-and-tube heat exchangers for the petroleum, petrochemical and natural gas industries. 2. Great things happen when the world agrees. The bottom row on the above heat exchanger symbol chart exhibits what are called "generic" HEx symbols; the function of the shell and tube are revealed but the actual structure of the HEx is not defined. The flow through the Kettle Type Reboiler is better defined in the symbol labelled "Reboiler" (far right column, just above the row of generic HEx symbols).

A phase change from vapor to liquid is ongoing in this exchanger.

The arrows on the "Reboiler-Labelled" symbol are explained below and illustrated by the photo on the below right. Can you find the big difference between the HEx at the top of this page and the animated HEx? the shell side and tube side may be bypassed to permit isolation of the heat exchanger for inspection, cleaning and repairs.

Here is an example of a 1-2 (1 shell pass and 2 tube passes) heat exchanger.

There are several kinds of HExes and therefore several kinds of HEx PFD and P&ID symbols. This symbol was created with Inkscape. A HEx Heater will have an arrow pointing downward drawn over the circle that represents the shell. PTOA Readers and Students will see the symbols in the above symbol chart appear in basic schematics like the one below.

PTOA Readers and Students understand the shellside and tubeside flow through this 2-pass U-Tube HEx. All structured data from the file and property namespaces is available under the. A shell and tube exchanger consists of a number of tubes mounted inside a cylindrical shell. 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. The upcoming PTOA segments feature equipment that is used to decrease process temperatures. Figure 1 illustrates a typical unit that may be found in a petrochemical plant. 2. Reboilers have weirs that help manage process liquid level and flow.

Two fluids can exchange heat, one fluid flows over the outside of the tubes while the second fluid flows through the tubes.

Another example of a 2-pass tube side HEx is featured at the top of this page.

The "Generic" PFD/PID HEx Condenser Symbol.

English: Symbol of a shell and tube heat exchanger.

Not so long ago, PTOA Readers and Students learned about process industry equipment that is used to increase process temperatures (e.g., fired heaters, steam from package boilers, exothermic reactions). Most shell-and-tube heat exchangers have multiple “passes” to enhance the heat transfer. Maximum exergy loss was observed for heat exchanger made of convex corrugated tube and concave corrugated shell.
