Design Tools
There exists many different tools used to design,
size and rate heat exchangers. Below are some of the tools and information we use on a routine basis:
Heat Transfer Tools:
Preliminary Heat Exchanger Sizing (Shell&Tube)
Determines the preliminary size for a shell and tube heat exchanger
based on the process information provided. The required heat transfer area, the number of tubes and the shell size are
calculated. This tool also calculates the utility requirements for achieving the desired heat transfer.
LMTD Calculator
Calculates the Log Mean Temperature Difference (LMTD) for given
inlet and outlet temperatures. The LMTD represents the temperature driving force for the given application.
Mean Metal Temperatures Calculator
Calculates the tubesheet mean metal temperature. It also
calculates the mean metal temperatures for the shell and the tubes. This information is needed to determine
if an expansion joint is required.
Heat Loss from Vertical Vessel
Calculates the ambient heat losses from a vertical vessel.
The calculations take into consideration the dimensions of the tank, the ambient conditions and the physical properties
of the liquid and the vapour.
Heat Transfer Information:
Provides typical fouling factor values for different process
fluids and various cooling waters.
Tube Material Specifications
Provides the nominal composition of various commonly used tube
materials with their corresponding ASME and UNS code numbers. This information is helpful when looking at the as built
drawings of existing heat exchangers.
Tubes Characteristics
Provides tubes characteristics such as B.W.G. gage, wall thicknesses,
external area and O.D./I.D. ratio for various tube sizes.
Pipe Dimensions
Provides wall thicknesses for welded and seamless pipes
of various sizes.
