FlowMac was developed by PaperMac AB<\/a>, and is now taken over by Opdal SimTech AS.<\/strong>
\n FlowMac is based on ExtendSim<\/a> a simulation software developed by Imagine That, Inc. FlowMac is only supported on windows-systems.
\n<\/strong><\/p>\n

FlowMac contains a series of libraries with in total more than 500 blocks as chests, pumps, valves, meters, head boxes, etc. Most of them designed for use in pulp and papermaking models, but other processes can also be modelled.<\/p>\n

<\/p>\n

There are more than 200 tutorial models in FlowMac to be used for training in use of the system, testing and understanding of important processes. Complete models for TMP and recycled fibre pulping lines, paper machines, boiler house and effluent treatment plants are included.<\/p>\n

The system is easy-to-use, modular with a graphical interface. Models are made by connecting process blocks into a flow sheet on the computer screen. The standard blocks in FlowMac should be sufficient for construction of a complete mill model, but customized blocks might be required.<\/p>\n

Customized blocks can be made according to customer specifications. FlowMac also comes with some blocks with open scripts, which serves as examples if the customer would like to create their own special blocks.
\nWith FlowMac the user can build quite accurate process models with simplified control system, and add more complex control functions in the positions needed, when needed.<\/p>\n

Some FlowMac Applications:<\/strong>
\n\u2022 Design of a Process, new or rebuilds
\n\u2022 Modelling of the Complete mill including Energy and Heat Balance
\n\u2022 Modelling of the Mill Environmental situation and evaluation of changes in the Mill or the Effluent Treatment Plant to improve the Mill Environmental situation
\n\u2022 Training of Machine Operators
\n\u2022 Trouble Shooting or detecting bottlenecks
\n\u2022 Simulation of Control Strategies for Buffer Storage Towers
\n\u2022 Modelling the economy of a product. Based on the Mass balance
\n\u2022 Modelling of fractionation in screens. 9 different fractions!
\n\u2022 Modelling of Ash and Bauer McNett fiber fractions on a SC paper machine for delay time studies for the fiber fractions at different operational scenarios
\n\u2022 Modelling of the steam and condensate system on a paper machine
\nHardware requirements<\/strong>
\nExtendSim and FlowMac will run on most computers, desktops and laptops. System requirements for FlowMac is the same as for ExtendSim\u00a0 http:\/\/www.extendsim.com\/sys_req.html<\/a>
\nA large screen is an advantage, but not required.
\nFilesize of the models are mostly dependent on how many iterations the models are set up to run, and how much data that have been stored in plotters inside the model.<\/p>\n

Dynamic Capabilities<\/strong>
\nFlowMac can do both dynamic simulation and steady state simulation. In the library Chests.Lix there is dynamic storage tanks with an ideal mixing, plug flow storage towers and the different storage tanks can be combined to represent the actual process.
\nWhen starting to build a new model in FlowMac, the user have to decide whether dynamic or steady state models are going to be made. Time lags in chests, pipes and paper machine sections are included.<\/p>\n

Simulation using FlowMac<\/strong>
\nDuring a simulation, flows of water, fibre, fillers, pressure, air, steam, condensate and temperature and so far up to 60 tracers are transferred between blocks. Summaries of operation costs and energy consumption can also be included. A simulation can be paused to modify process parameters for sensitivity analysis. Sliders allow continuous changes of important parameters, such as lip opening of the head box or first pass retention of fibres in the wire section. With FlowMac there is also other ways to control the simulation. For a paper machine, you can create a production plan and let this production govern the simulation. For other parts of a Mill you can create an operational pattern (Power Shedding, Planned Maintenance Shuts ++) and look at utilisation of buffers.<\/p>\n

Simulation Outputs from FlowMac<\/strong>
\n\u2022 Data can be saved in Plotters
\n\u2022 Data exported to Excel,
\n\u2022 Text reports: Mass Balance summary, engineering data for Pipes, Pumps, tanks and other equipment.
\n\u2022 Utilise the \u201cNotebook\u201d function in ExtendSim where the user can create a report containing exactly the wanted data.
\n\u2022 Data can also be stored in a Database.
\n\u2022 Data can be imported and exported via an OPC-server<\/p>\n

FlowMac Development<\/strong>
\nFlowMac is continuously developed to fulfil customer requirements and a long term goal is to extend FlowMac to other process areas.<\/p>\n
