HSC Chemistry

HSC Chemistry is the world’s most widely used computational thermochemistry application.

Chemical Reaction and Equilibrium Software HSC Chemistry is the world’s favorite thermochemical software with a versatile flowsheet simulation module. HSC is designed for various kinds of chemical reactions and equilibria calculations as well as process simulation.

The current HSC version 7 contains 22 calculation modules:

  1. Sim – Process simulation
  2. Reactions Equations
  3. Heat and Material Balances
  4. Heat Loss Calculator
  5. Equilibrium Calculations
  6. Electrochemical Cell Equilibriums
  7. Eh-pH Diagrams – Pourbaix
  8. H, S, C and Ellingham Diagrams
  9. Tpp Diagrams – Stability diagrams
  10. Lpp Diagrams – Stability diagrams
  11. Water – Steam tables, etc.
  12. Formula Weights
  13. Conversions – Species to elements
  14. Mineralogy Iterations
  15. Periodic Chart – Elements
  16. Measure Units
  17. HSC AddIn Functions
  18. Data – Statistical analysis
  19. Geo – Mineralogical calculations
  20. Map – GPS material stock
  21. Fit – Numerical Data fit
  22. Aqua

The name of the program is based on the feature that calculation modules automatically utilize the same extensive thermochemical database which contains enthalpy (H), entropy (S) and heat capacity© data for more than 25,000 chemical compounds. This database is equivalent to more than twenty thick data books. HSC contains also other databases:sim-user-interfaceb1

  1. H, S and Cp Thermochemical Database
  2. Water Steam/Fluid Database
  3. Heat Conduction Database
  4. Heat Convection Database
  5. Surface Radiation Database
  6. Gas Radiation Calculator
  7. Particle Radiation Calculator
  8. Elements Database
  9. Measure Units Database
  10. Minerals Database with 3581 minerals
  11. Aqueous Solution Density Database
  12. The Pitzer parameter database

The objective of HSC is to make conventional thermodynamic calculations fast and easy to carry out using personal computers. Therefore HSC has a wide range of applications in scientific education, industry and research. Thermochemical calculations are useful, for example, when developing new chemical processes and improving old ones. HSC Chemistry is also a useful tool for universities and schools in chemical practicals and studies.
Traditionally, thermodynamic calculations based on experimental or assessed data have utilized stability functions in various thermodynamic data books and papers in scientific journals. The difficult searching stage and complicated calculations, as well as inconsistencies arising from different selections of standard and reference states, have made this calculation procedure quite time-consuming.
HSC Chemistry offers powerful calculation methods for studying the effects of different variables on the chemical system at equilibrium. For example, if the user gives the raw materials, amounts and other conditions of almost any chemical process, the program will give the amounts of the product as a result. HSC also makes heat and material balance calculations of different processes much more easily than any manual method. The Eh-pH-diagrams option also offers a very fast way of studying the dissolution and corrosion behavior of different materials.
Of course, HSC cannot solve all chemical problems, because it does not take into account the kinetics (rates) of the chemical reactions and non-ideality of solutions. However, in many cases it is a very inexpensive and useful tool which helps to find the optimal reaction conditions and yields for experimental investigations without expensive trial-and-error chemistry.
