... is a general tool for the description and simulation of dispersed systems. Main applications are industrial crystallization, dispersion, granulation, particle reactions in two phases and general reaction-convection-diffusion systems. So Parsival has proven to be a first choice for particle balance modeling.

All results are presented in online-graphs during simulation or optimization runs. Import and export of results and data in text files or via the COM-interface ensure the communication with other program packages.


  • Rigorous and modular treatment of particle size distributions in heterogeneous process units
  • Reaction step patterns for particle growth, nucleation, agglomeration, breakage, fine's dissolution, convection, diffusion, boundary conditions, kinetic reactions
  • Flow sheets with classified flow and exit
  • Parameter estimation including fit of full particle size distributions
  • Applications are
