PRODUCTIVITY TOOLS

This release of VMGSim contains an impressive list of general enhancement and productivity upgrades, including VMGSim’s ProTreat® Link unit operation. This highly anticipated feature was developed in an exclusive partnership with Optimized Gas Treating to enable a live, bi-directional link between VMGSim and ProTreat. Users can now integrate their models seamlessly and take advantage of the rigorous calculations and specialized features that each software package has to offer in a unified environment.

New economics module

• VMGSim 9.5 includes the option to estimate unit operation focused capital cost and operating expenditure resulting from energy consumption. A pro forma income statement can be generated for an entire simulation taking into account capital contingency, revenue streams, and direct and indirect expenses. The income statement can be customised and used as the basis to refine, reject or optimise a simulation case.

Flash emissions module

• Monitor emissions throughout your flow sheet

• Account emissions by group such as VOC, GHG, CO2 Equivalent and BTEX

Flexible and comprehensive Excel add-in

• The new VMGSim Excel add-in provides streamlined tools to interact with simulation models directly from Excel®. Simulation data can be extracted and linked to any Excel Workbook, making it available to templates like equipment sizing- sheets or custom reports. In addition, live simulation models can be linked to tailored Excel interfaces.

Any CAPE-OPEN compliant unit operation can be added to the simulator

DOWNSTREAM

VMGSim’s downstream modeling capabilities continue to be enhanced with a new CCR Reactor unit operation as well an extensive set of enhancements to existing reactor suites functionality. The CCR unit operation provides the ability to model the common configurations of reformers with the level of fidelity that is to be expected with the refinery reactor suite in VMGSim.

Added rigorous Continuous Catalytic Reforming (CCR) to our suite of refinery reactors:

• Able to model multi stage catalytic moving and fixed bed refinery reactors

• Predict product yields and properties such as RON, BTEX wt, H2 wt

• Complete catalyst deactivation model containing acid/metal function deactivation including coking, poisoning and sintering mechanisms

Numerous enhancements to our high fidelity reactors such as:

• Continuous Improvement to kinetics of coke growth formation

• Improving convergence time of the refinery reactors

• Claus Waste Heat Boiler - added calculation for the utility steam side

• Fischer Tropsch - added rating calculations

• Ethylene Cracker - the pyrolytic effect of DMDS on light feed stock’s coke growth has been reduced to match better with known data

UNCONVENTIONAL

VMGSim 9.5 includes functionality to make it easier to take advantage of VMGSim’s advanced characterization methodologies for unconventional fluid modeling.

The oil source unit operation has been enhanced with specific entry options for typical analysis available for tight fluids as well as solvent deasphalting. This allows for more streamlined data entry and utilization of available data using VMGSim PIONA based characterization technology. The tight fluid option is applicable to tight and shale formation gases and liquids using extended hydrocarbon analysis. These enhanced characterizations can be used throughout VMGSim including the new recombination operation.

Use PIONA based characterization for enhanced tracking of components and properties throughout the flowsheet

Dedicated Module for characterization of:

• Tight/shale fluids using extended hydrocarbon analyses

• Heavy oils using a SARA assay

• Solvent deasphalting using asphaltene precipitation experimental data

Recombination unit operation to reconcile compositional analyses with field flow data

• Recombination Unit Operation is useful for reconciling gas and liquid flows based on reference well test conditions when the operating conditions change

CN Analysis Unit operation to generate extended hydrocarbon analysis based on stream data

EMISSIONS

• Flash Emissions - Material streams now have the ability to report flash emissions as CO2 Green House Gas Equivalent or grouped by HAP, VOC, GHG, BTEX, NOx, SO2, CO and CO2

• Emissions Summary - A summary of all emissions can be inspected and configured in the new Emissions Summary module

• Tank Emissions:

o Emissions results can now be displayed by component group

o Added emissions tab to separators (enabled in Settings tab)

o Added option to display losses in either mass or flow units

• Tank Emissions - Reports are based on pollutants only instead of all components
