The general rule of using HanUtil is as followings.
- The security option of Excel shall be set to the "Low" at Tools/Macro/Security menu of Excel before start HanUtil.
This requirement is to use the Excel-macro functions included in the HanUtil Excel formats of HanUtil package. - When start HanUtil, the login dialog box will be appeared.
Input correct User ID with Password, which was set while registering HanolTech member. - If you want to open new program module, select "File / New Application" menu or click
icon and then select appropriate program name. - If you want to open saved HanUtil file, select " File / Open File" menu or click
icon. - Input the required data on the new module window.
In general, the field with color of
indicate the required data, and the field of color 
indicate the optional data. - After input of data, select "Run" menu or click
icon to perform the calculation. - If needed, correct input data and recalculate.
- If you want to save the opened window to a file, select "File / Save File (As)" menu or click
icon. - If you want to close the opened window, select "File / Exit" or "File / Close Application" menu.
- The run charge will be based on the kind of used module and the number of calculation,
and the fee will be charged for the result printout case only after successful execution.
The use log can be viewed on the real time basis from "Help / Member Use Log" menu.
Steam Table- Calculation of steam saturation pressure at given temperature
- Calculation of steam saturation temperature at given pressure
- Calculation of latent heat when steam is in saturated condition
- Calculation of physical properties (density, viscosity, thermal conductivity, specific heat) of water and/or steam at given pressure and temperature
Heat Curve for Ideal Mixture- Generation of boiling or condensing curve for the ideal mixtures
- Component number of 1 to 5 are for the non-condensing component.
- Component number of 6 to 10 are for the condensing (or having the possibility of condensing) component
- Calculation of enthalpy and equilibrium at the given temperatures up to 20 points, including dew and bubble points, which are inserted automatically when these points are included in the given temperature range
- Calculation of Differential Flash when condensing
- The graph of Vapor Fraction vs Temperature and Vapor Fraction vs Enthalpy
- Useful for the generation of condensing curve for the design of ejector condenser,
or for the design of ejector system itself.
Line Sizing- Useful for the determination of pipe line or nozzle size
- Functions for the calculation of Liquid, Gas, Mixture or Compressible Vapor
HEX Size Estimation- Calculation of heat transfer area for the shell and tube type heat exchanger
- Direct input of heat transfer coefficient of shell side and tube side
- Tube material table is included
HEX Weight Estimation- Calculation of Bundle, Empty and Full Water Weight for the shell and tube type heat exchanger
- Possible to estimate the cost of shell and tube type heat exchanger for the proposal work
- Material table for shell, tube and channel is included
- Can calculate with minimum number of input data. It becomes the more accurate with the more input data.
Thus this is the best software for the proposal work. - Generation of heat exchanger list
- Commands for one heat exchanger in the sheet named "Estimation Sheet"
(Calculate) : Calculation of weight for the current heat exchanger (Charged)
(Calc & Save) : Calculate and Save (Charged)
(Clear) : Data Clear for the current heat exchanger (Free)
(Save) : Data Save for the current heat exchanger (Free)
(SaveNew) : Add heat exchanger and Save current data to the added heat exchanger data (Free)
(PreviousHEX) : Load the data of previous heat exchanger (Free)
(GoAnyHEX) : Load the data having the serial number of ... (Free)
(NextHEX) : Load the data of next heat exchanger (Free)
(Unit) : Setting of unit system (Free)
(PJT) : Setting of project description (Free)
- Commands for all heat exchangers in the sheet named "Data Saved"
(CalcBatch) : Calculation for all heat exchanger from saved data (Charged, Unit Charge * Number of Items)
(Sort) : Rearrange by the modified serial number or by the modified item number (Free)
(List) : Generate the list of heat exchanger from saved data (Free)
RhoV2- Calculation of nozzle entrance and exit RhoV2 (Density * Velocity * Velocity) for shell and tube type heat exchanger
- Calculation of "Height Under Nozzle", if RhoV2 value is entered
- Simultaneous calculation for the case with and without impingement plate
- Simultaneous calculation for the case of wide impingement, which has flat impingement extended to the circumference of shell
Surface Condenser- Performance calculation according to HEI(Heat Exchanger Institute) "Standards for steam surface condenser"
- Heat transfer and tube side pressure drop calculation
- Checking of input data and result according to the standard and limitation in HEI
- Input of fouling factor instead of cleanliness factor (or both input) is possible
- Having HEI standard parameter according to tube material and thickness
Combustion- Combustion calculation according to API Standard 560
- Gas Firing, Liquid Firing and Mixed Firing
- Can omit the input data for the property of fuel, which is tedious to find, because HanUtil has its own calculating routine
- Embedded gas enthalpy and gas standard of ASME PTC4-4 and PTC22
- Calculation of acid dew point according to the amount of SOx. This enables designer to avoid low temperature corrosion.
- The flue gas physical property (density, viscosity, thermal conductivity, specific heat, enthalpy) table in "Flue Gas Properties" sheet is automatically updated when doing the combustion calculation in the "Combustion Calc" sheet.
- Air preheater calculation and heat balance calculation is done in the "APH Calc" sheet.
This calculation includes the temperature calculation of all points within the fired heater system and also calculate expected minimum metal temperature within APH.
Heat Loss to Air- Originally, this module is developed to calculate the temperature profile of fired heater wall,
but this module is also useful for the calculation of one dimensional heat transfer of any kind
because its calculation is based on the heat balance of one dimensional (flat or cylindrical) thin element. - Considering the change of thermal conductivity according to temperature of inside material
- Considering the heat transfer through refractory supporting anchor
- Having the thermal conductivity data with temperature for the material of refractory, insulation and Metal
- Calculation of radiation and convection for the inside surface with given emissivity and heat transfer coefficient
- Calculation of radiation and convection for the outside surface according to ASTM C680 method with given wind velocity
- Having the special layer material which can input heat transfer coefficient, thermal conductivity or thermal resistance directly
- Calculation of heat stored within the material from ambient temperature
- Graph for the temperature within material
