Introduction

This page provides detailed descriptions of the SysCAD solver and add-ons that are available when you purchase a SysCAD license.

Please contact Kenwalt for a pricing document for the SysCAD licenses and add-ons.

Solver Modes

SysCAD is offered in two main solver modes and with a number of optional add-ons. This structure allows clients the flexibility to purchase only the SysCAD features that they need for their requirements.

When purchasing or leasing a license one or both of the solver modes must be selected. The two main solver mode options are Steady State (ProBal) and Dynamic Transfer.

The solver modes include a number of standard models as described in the sections below. Both SysCAD solver modes will perform mass balance calculations. However to include any energy calculations the Energy Balance add-on is required.

Steady State (ProBal - Process Balance)

This mode is used to simulate a plant model under steady state conditions in order to produce a plant mass balance, or mass and energy balance with Energy Balance add-on. There are many and varied applications for steady state modelling throughout a project’s lifecycle. Examples include:

  • Feasibility studies;
  • Assessing flowsheet options;
  • Optimisation studies;
  • Data evaluation;
  • Operations tool;
  • Training; and
  • Planning and development of a process knowledge base.

Dynamic Transfer

This mode is the basic dynamic license option for flow based dynamic simulation. It is used to represent unsteady state conditions and more complex control processes. Pipes are usually modelled as transfer links, where fixed flow rates or flow rate capacities are specified directly. It is well suited for the following applications:

  • Material handling processes;
  • Surge and availability studies;
  • Production planning forecasts;
  • Design verification;
  • Plant equipment sizing;
  • Supporting process control strategy development;
  • Metallurgical accounting;
  • Process understanding, studies, optimisation;
  • Control system (e.g. PLC) testing; and
  • Operator training.

Solver Mode Functionality add-ons

There is currently one solver mode functionality add-on.

Energy Balance add-on

This add-on is required to perform energy balances and/or heat transfer calculations in the solver for a project. If this add-on is not included only mass balances are performed.

Model Library Add-Ons

Both Steady State and Dynamic solver modes include a substantial set of standard models. Extra model add-ons are available to provide access to additional models that may be required depending on the process to be simulated.

Not all models operate in all of the simulation modes. All the models are described in the online SysCAD documentation.

Standard Model Set

The standard model set is included with both the Steady State (ProBal) and Dynamic solver modes and includes the basic building blocks, such material source/sink, pipe, tank, tie (mixer/splitter), controllers, reactions and the standard species properties model. Slightly more advanced units such as pumps, valves and various separation units (thickener, washers, filters, etc) are also included.

A number of standard models are only functional if the Energy Balance add-on is included. Examples include heat-exchangers, flash tanks, contact heaters, barometric condensers and the environmental heat exchange option.

The dynamic solver mode includes a conveyor belt model and some extra “controller” models (profile, events, statistics, etc).

Alumina Add-on

This add-on is used for modelling alumina refineries. It allows Bayer Properties models to be used and also includes a precipitation unit model.

Prerequisites:

  • The Energy Balance add-on.

Potash Add-on

This add-on is used for modelling potash processes. It allows KCl-NaCl or KCl-NaCl-MgCl2 Properties and solubility models to be used and also includes an evaporator unit model.

Prerequisites:

  • The Energy Balance add-on.

Sugar Add-on

This add-on is used for modelling sugar factories. It allows Sugar Properties models to be used and also includes various sugar factory specific models such as a vacuum pan filter unit model.

Prerequisites:

  • The Energy Balance add-on.

Size Distribution Add-on

This is used for modelling processes that require Particle Size Data (PSD) entry, tracking and manipulation. This add-on includes unit operations such as the crusher, screen and cyclone.

Client Model (SMDK Runtime) Add-on

The SMDK Runtime add-on is required for:

  1. Any client specific property or unit operation models delivered as a client specific add-on developed by Kenwalt (or a third party).
  2. Any property or unit operation models developed by a client for their own use using a Developer License with the full SysCAD Model Developers Kit (SMDK).
  3. Any use of commercial or 3rd party software integrated into SysCAD as a SysCAD add-on. For example OLI, LIMN or in-house libraries.

Note: The SMDK Runtime add-on does NOT provide the functionality for the users to develop their own models. Contact Kenwalt for information on Developer License for this functionality.

Thermodynamic Engine Integration Add-Ons

SysCAD can be integrated with various 3rd party thermodynamic calculation engines and databases.

OLI Add-on

This is used for including OLI Systems Electrolyte thermodynamic calculations and aqueous chemistry in SysCAD. An appropriate OLI License is required. Contact OLI Systems for further information.

Prerequisites:

  • The Energy Balance add-on.
  • The SMDK Runtime add-on.
  • OLI Engine license from OLI Systems.

PHREEQC Add-On

Only available in Build 138. This is used for including PHREEQC thermodynamic calculations and aqueous chemistry in SysCAD.

Prerequisites:

  • The Energy Balance add-on.
  • The SMDK Runtime add-on.

ChemApp FACTSage Add-On

Only available in Build 138. This is used for including ChemApp (FACTSage) thermodynamic calculations in SysCAD. An appropriate ChemApp License is required.

Prerequisites:

  • The Energy Balance add-on.
  • The SMDK Runtime add-on.
  • ChemApp license from GTT-Technologies.

AQSol Add-On

Only available in Build 138. This is used for including AQSol thermodynamic calculations in SysCAD. An appropriate AQSol License is required.

Prerequisites:

  • The Energy Balance add-on.
  • The SMDK Runtime add-on.
  • AQSol license from Aqueous Solutions ApS, Denmark.

Dynamic Mode Functionality add-ons

There is currently one dynamic solver mode functionality add-on.

SysCAD Marshal (OPC) Add-on

SysCAD can be configured as an OPC Server and/or as an OPC Client. The SysCAD OPC Client runs in a separate window and is called “SysCAD Marshal”. OPC is an industry standard and is used in dynamic projects to connect SysCAD to other OPC Clients or OPC Servers such as software (e.g. Scada, HMI, etc.) and hardware (e.g. PLC, DCS). The main applications for OPC in SysCAD are control system testing and operator training.
