Shell & Tube Heat Exchanger Design

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

S&THex is a software tool that is made to demonstrate the chemical design & rating calculations of Shell & Tube Heat Exchangers. Unlike other tools, ensures that the calculations are performed step by step to help in understanding the design calculations.
Please note that the software can only do the basic chemical design & rating calculations of shell and tube heat exchangers and some mechanical design calculations.

Shell and Tube heat exchanger design Software Features

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

Results:

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

Calculations:

  1. Unknown Flow rate on either shell or tube side
  2. Unknown temperature on shell side or tube side
  3. Unknown exit temperatures on both sides
  4. Duty, Area, Shell and Tube velocities
  5. Number of Baffles and Baffle spacing, Number of tubes, Scale resistance (dirt factor)
  6. Overall heat transfer coefficient for both Clean and Fouled conditions
  7. Select from different correlations to calculate shell or tube heat transfer coefficient
  8. Shell/Tube side Reynolds & Nusselt numbers
  9. Pressure Drops
  10. Recommended minimum shell thickness, minimum recommended number & diameter of rods.
  11. Calculate Shell/Nozzle/Channel/Head/Tube sheet Thickness.
  12. Number of transfer units, Effectiveness, Thermal capacity ratio
  13. Pumping power / Inlet and Exit Nozzles pressure losses / Scale resistance Calculators
  14. Ability to import properties to Shell/Tube sides form Microsoft Excel very useful if you want to import your own physical properties

Included Databases:

  1. 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.
  2. Estimate mixture properties. (ALL ESTIMATION METHODS CURRENTLY SUPPORT LIQUIDS ONLY)
  3. Ability to add your own properties in the additional user databases.
  4. Tube counts
  5. Fouling factors and Overall heat transfer coefficients included.
  6. Material thermal conductivities
  7. 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.
