Shell and Tube Heat Exchanger Design (S&THex). Very easy to use and user friendly.

S&THex is a software tool that is made to demonstrate the chemical design and rating calculations of Shell & Tube Heat Exchangers. The software unlike other tools, ensures that the calculations are performed step by step to help in understanding the calculations.

Software Features

• Step by step design and rating calculations.
• Support S.I Units and English (U.S) Units of measurement
• Rating and Design Modes• Units converter containing 23 measurements and 200 units conversions
• Save, Load and generate result in different formats

Results:

• Generate Results and export it to Shell & Tube Engineering Data sheet that can be also saved as a .pdf document.
• Export results to Microsoft excel generated data sheet for editing.
• Export Results summary to .csv file format that can be opened in Microsoft Excel• Export Results summary to .rtf file format that can be opened in Microsoft Word
• Print preview / print Results summary

Calculations:

The software performs many thermal analysis calculations and some mechanical calculations, as it is too lengthy to list all the calculations, a summary has been listed below.
• Unknown Flow rate on either shell or tube side
• Unknown temperature on shell side or tube side
• Unknown exit temperatures on both sides
• Duty, Area, Shell and Tube velocities
• Number of Baffles and Baffle spacing, Number of tubes, Scale resistance (dirt factor)
• Overall heat transfer coefficient for both Clean and Fouled conditions
• Select from different correlations to calculate shell or tube heat transfer coefficient
• Shell/Tube side Reynolds & Nusselt numbers
• Pressure Drops
• Recommended minimum shell thickness, minimum recommended number & diameter of rods.• Calculate Shell/Nozzle/Channel/Head/Tube sheet Thickness.
• Number of transfer units, Effectiveness, Thermal capacity ratio
• Pumping power / Inlet and Exit Nozzles pressure losses / Scale resistance Calculators
• Ability to import properties to Shell/Tube sides form Microsoft Excel very useful if you want to import your own physical properties Included

More Features

Databases:

  • Estimate the Physical properties of pure components for more than 1450 components; the database has the ability to estimate Thermal Conductivity, Density, Heat Capacity and Viscosity. The database also included critical properties, boiling and melting points and come as a standalone interface but easily integrated with the software.
    • Estimate mixture properties. (ALL ESTIMATION METHODS CURRENTLY SUPPORT LIQUIDS ONLY)
  • Ability to add your own properties in the additional user databases.
  • Tube counts
  • Fouling factors and Overall heat transfer coefficients included.
  • Material thermal conductivities
  • Standard pipe sizes and Birmingham Wire Gage Scale

Below are a tabulated list of calculations, this list below isn’t conclusive and other calculations are also performed based on conditions.
