MySep Main Features


MySep software has a wealth of features, that provide engineers with tools and insights to design and evaluate separation vessels in a comprehensive and efficient manner. 

Phase separation

  • Gas - liquid separation
  • Liquid - liquid separation
  • Liquid - sand separation

Automatic vessel sizing

  • Full automatic sizing of the vessel based on selected equipment and other optional criteria
  • Side-by-side comparison of multiple vessel configurations
  • Automatic vessel weight calculation for each vessel configuration

Simulator communications

  • Bi-directional communication with process simulators:
    • Aspen HYSYS®
    • Petro-SIM™
    • ScimSci™ PRO/II
    • UniSim® Design
    • VMGSim™
  • Pull process data directly from process simulator into MySep
  • Send vessel carryover and pressure drop to simulator
  • MySep-RunTime geometry file generation

Vessel Motion

  • The Motion module enables time transient simulation and analysis of liquid level height behaviour in the vessel as a result of motion of the facility (e.g. and FPSO)
  • Time transient calculation of liquid level heights
  • Automatic checking of internals against the dynamic liquid levels
  • Warnings are shotn if the moving liquid levels cause operational issues for the separation internals
  • "Video" mode that shows the dynamic level behaviour in the vessel (pitch and roll views)
  • Level monitor graphs vs time
  • Data export to Excel spreadsheet

Vessel weight

  • Calculation of shell and heads thickness
  • Vessel weight calculation
  • Nozzles and internals weight calculation
  • Selectable vessel codes: ASME VIII Div 1, ASME VIII Div 2, PD 5500
  • Selectable material of construction

Input

  • Input up to 6 design and operating cases
  • Selectable input units (SI/metric and English/Imperial and combinations) and automatic conversion upon unit selection change
  • Pull data directly from HYSYS, Petro-SIM, PRO/II, UniSim Design and VMGSim
  • Import case data from Excel spreadsheet
