ProSimPlus 3.5.18

  • Improvement of the economic evaluation module: users will find it easier to use this module thanks to the automation of the retrieval of the unit operations parameters taken into account in the economic evaluation.
  • Temperature profiles in decoupled heat exchangers: from now on, when heat exchangers are represented by two independent modules (one that sets the temperature of one stream and generates the heat duty required; the other that receives this heat duty and calculates the temperature of another stream), it is possible to generate the temperature profiles and temperature differences profiles using the scriptlet: "Temperature profiles of the heat exchanger".
  • New feature to calculate the NPSH (Net Positive Suction Head) in the pump unit module.
  • New option for displaying 2D profile plots: users can now change the axes in the "profiles" tabs of the modules. For example, the user can change the profiles representation in the columns.
Simulis Thermodynamics 2.0.17

  • Addition of the PPR78 generalized mixing rule. This mixing rule adopts the formalism defined by Jaubert et al. and allows the use of group contribution parameters of the PPR78 model. It can be used with any cubic equations of state (RK, PR...) and any alpha function. Therefore, this mixing rule allows any cubic equation of state to be predictive. With this approach, users can also combine binary interaction parameters identified on experimental data with other binary interaction parameters predicted by group contribution methods.
  • Addition of the "Generalized Twu-Nancy" alpha function. This alpha function has a formalism identical to the Twu alpha function previously available, but the parameters have been modified so that the alpha function respects the thermodynamic consistency constraints. Thus, the use of this alpha function allows a better modeling of the fluid properties.
  • The volume translation parameter for cubic equation of state has been added to the list of predictable properties. Previously, this was done automatically in the thermodynamic code, which did not allow users to choose, nor to know what value was used. The information is now clearly available and it is possible to choose the method that one wishes to use to predict this value.
  • Sour Water model: for this thermodynamic model that allows the modeling of many electrolytic systems, the consideration of the NH4Cl crystallization has been added.
  • Addition of the "copy and paste" feature and possibility to calculate simultaneously several residue curves within the calculation service "residue...".
BatchReactor 1.4.16 - BatchColumn 1.4.16

  • Possibility of carrying out an extrapolation calculation of the reactor or boiler of the column. Very useful for scale-up purposes, the process extrapolation techniques are based on the principles of similarity which stipulate that the ratios of one or more parameters must be the same on both scales in order to reproduce the same phenomena to obtain a final product of identical quality. In the case of a stirred tank, there are five such principles: geometric similarity, kinematic similarity, dynamic similarity, thermal similarity, chemical similarity. The software calculates the invariants that can be used in an extrapolation of a mechanically stirred tank, thus enabling the user, depending on his field of application, to know the characteristics of the equipment for production on a different scale from the one initially simulated.
  • Calculation of the vortex depth inside the reactor or the boiler of the column. Users are able to learn more about the influence of the mixing parameters on this phenomenon.
  • Possibility to define several identical agitators on the same shaft for a given number of stirring devices already available.
  • Addition of a high efficiency impeller with optimized blades (Chemineer HE3).
  • Addition of a curved blade turbine (Pfaudler type) in the long list of agitators already available in the software.
