Changes in Petro-SIM 4.1 Builds

SIM Suite v4.1 Service Pack 3 - Release Notes

These are the issues addressed by 4.1 SP3 (build 707)

In addition to the items below, please review information about a bug fix to feed viscosity handling in the FCC and Hydroprocessing reactors.

New Features

  • Optimiser - Add new optimiser diagnostics that track the status of recycles, adjusts, and attachments and report when they are worse than initial conditions.
  • Assay Synthesis - add two new synthesis parameters to give users better control over the naphtha modification process. Change also adds more diagnostics to help tell people what is going on. Parameters are:
    • Naphtha Modification - Scope: this lets you control the modification range relative to known or estimated component data
    • Naphtha Modification - Limit Temperature: this is used in conjunction with one of the Scope options
  • Reformer - supports a Combined Effluent product configuration for use with Once-Through Hydrogen

  • Optimiser - Promote step size to the optimizer view, it was previously set heuristically behind-the-scenes with little recourse for user intervention
  • Optimiser - Start reporting the initial values on optimizer iterations page, also fix logic hole in convergence monitor where it could have been stopping the optimization too quickly when multiple cases were being used (wasn't distinguishing which case iterations were coming from)
  • Fix recycles reporting they are not converged to the KPI Utility when they really are.
  • Bugzilla 5034 - Correct issue where Calibration Application refuses to accept feed rate after calibration.
  • Bugzilla 4877 - fix issue where meters were not always pushing out values when "Send on Execute" was enabled, which raised other issues around the exceedingly large default tolerance for StdLiqVolFlowVar.

  • Bug fix to make response factors default to 1.0001 to keep use original calibration factors in predict.Set response factor at 1.0 will still apply new default calibration factor value when model detects new feed type. This replaces the old default response factor of 1.0 that causes wrong behavior when just doing predict step out runs. Bug was reported in Helpdesk F0033115 for V4.1SP1

SIM Suite v4.1 Service Pack 1 - Release Notes

These are the issues addressed by SIM Suite v4.1 Service Pack 1 (build 686).

New Features

  • AROM-SIM - this service pack introduces a new Aromatics Reactor object offering auto-calibration and tuning of key reactions. Like the new Isom Reactor introduced in the original 4.1 release, this reactor operates within the standard Petro-SIM calibration environment and can be used in conjunction with auto-generated Reactor Workbooks in Microsoft Excel. This reactor object provides an alternative to the existing Aromatics Transalkylation and Xylene Isomerisation reactor objects, with revised chemistry that should offer greater ease of use and more robust predictions. The reactor is available to licensees of the existing AROM-SIM objects
  • FCC-SIM - the reactor now supports a mid-riser injection point on the 2nd riser of two riser systems.
  • Data Reconciliation - this now supports calculating an adjusted raw overall mass balance that can back-out the effect of unmeasured constituents like sulfur and nitrogen across hydroprocessing reactors and inerts across FCC reactors.

Documentation

Both the pdf version of the documentation and the online help files have been updated to reflect any and all changes made in this service pack.

Security Utilities

  • KBC License Tester - correct install license file feature so it understands additive licenses and doesn't try and yank the feature first.
  • KBC License Tester - make sure ability to save changes to the KBCLicServers file only applies when running with admin rights.
  • Bugzilla #4227 - Make commuter manager trap use of ~ in kbclicservers and warn user since it prevents use of commuted licenses.
  • Made the security heartbeat a little more tolerant of intermittent network outages.
  • License Tester verifies admin rights before running cleanup tool since lsclean requires them
  • Commuter Manager aborts attempts to commute codegen 11 or higher licenses from license servers running version 8.1.0 or lower. (An 8.1.0 license server will handle these licenses for normal network operations but has bugs preventing commuting).
  • Commuter Manager limits the maximum checkout days to the lesser of 30 and any maximum set on any license selected for commute.
