Changes in Petro-SIM 5 Builds

SIM Suite v5.0 Service Pack 1 - Release Notes

These are the issues addressed by 5.0 SP1 (build 1046). There are two significant bug fixes that we bring to your attention:

  • We have corrected how feed viscosity is handled in FCC Feed characterisation. Please review information about this change at feed viscosity handling.
  • We have corrected the PONA volume <> weight interconversion methods, introducing a new PONA Interconversion method option that has two settings below.
    • Dynamic ratio based on characterisation function which is the default. This calculates weight from volume using PONA density estimates calculated from a carbon-number based characterizing function. This method gives more consistent results in the naphtha region between bulk PONA values and values summed from the Extended Components view.
    • Fixed ratios between PONA Types is the original Petro-SIM 4.0 method

You will also see improvements to managing database connections with a new button/indicator on the top right of the menu bar. These improvements include explicit support for Flaretot databases.

    • updates the various PONA by wt correlations to recognise this new method
    • extends range of non-paraffin species recognised in calculating vol% paraffins by difference (was gas components like H2, N2 etc but now also oxygenates and so on) and hence in calculating wt% paraffins
    • corrects density functions used in new method to (a) use the ratio of species density to stream density as a multiplier and (b) to modify the naphthenes formula with a dampened version developed from SIM model characterisation technology
    • corrects handling of paraffins to include normal as well as iso paraffins
    • fills a few holes in the pure component database around these properties
    • corrects the calculation method in situations where assay data available so it is explicitly sum(LVi*PONAFractioni*SGpona(i))/sum(LVi*SGi) which takes composition into account and has the result that bulk PONA wt% properties in the naphtha region will match those summed from individual component contributions in most cases (this rule depends on how the assay has been synthesised)
    • modifies single point PONA synthesis to make use of detailed component data where available in same way as multipoint synthesis. Corrects consistency of assay between bulk properties and detailed distribution.
