Purpose of the program

The MIXTURE software is the component of the Thermal Safety Software (TSS) series and represents a powerful and convenient tool for calculation of physical properties of liquid and gas multi-component non-ideal mixtures.

MIXTURE 2.8 can be used as a stand-alone application or in conjunction with DesK and InSafer software. MIXTURE is an obligatory part of the ConvEx-Pro, BST and Vent software.

Handling data

MIXTURE is essentially based on the MS Access. It is used as for storage of physical-chemical properties of an individual substance as for storage the Projects. A MIXTURE Project comprises the mixture composition and reference to the corresponding project is saved in a data Project of BST, VENT, ConvEx Pro, etc. A Project is composed by the User while working either with MIXTURE in autonomous mode or when MIXTURE is called in the spawned mode from other TSS programs.

Functionality of MIXTURE 2.8:

  • Calculating properties for gas and liquid mixtures:
  •         thermodynamic  properties;
  •         equilibrium properties;
  •         transport properties (thermal conductivity, viscosity, binary diffusion coefficients)
  • Tacking account of non-ideality of a mixture by using cubic equation of state and UNIFAC;
  • Using non-additive mixing rules;
  • Estimating properties of pure compounds by using original technique;
  • An internal data base containing carefully verified properties of more than 250 substances;
  • Possibility to link MIXTURE to commercial databases such as DIPPR 801 and PPDS
  • Possibility to link MIXTURE to a Customer specific data base can be provided on demand.

  1.  When installing the program under Windows 7 and higher we strongly recommend to use the default path  C:\Users\[username]\CISP\[program]
  2. When installing new versions of TSS applications one can meet the problem with Anti-virus tools you use.  Some of them may suspect that TSS programs are hazardous ones. Please don't worry. This may happen  due to new  powerful protection system (provided by  the Enigma Protector - one  of the world  leaders in this  area) which  sometimes causes alarm because anty-virus tools cannot look  inside the protected code. As a result the approcation will be blocked. To avoid such problem ask your IT service to exclude .Users\[username]\CISP  folder from virus  check  ​
    CISP guarantees that TSS is 100% clean, which means its applications do not contain any form of malware, including but not limited to: spyware, viruses, trojans and backdoor.
  3. Be aware - even if you are the licensed user of this program you will have to get new registration key. Please email us the request and don't forget to indicate your company and your name
  4. IMPORTANT! When installing MIXTURE you should run setup.exe "As Administrator". The simple way to run it as an administrator in Windows 10 is to find the setup you want to run on the disk or CD, right click and select 'Run as administrator' 

ATTENTION! Be aware that on the expiration of the Warranty/maintenance Period the License on any TSS application remains valid for the version last updated during maintenance Period. Therefore if your maintenance has expired you wouldn't be able to use new updatesIf you nevertheless download the setup of new version and replace your working version with new one it won't work and you will lose working program! To avoid such situation check please whether you have valid maintenance before downloading any TSS program.
