Dynamic Process Simulation (DPS) can make a significant difference to the final outcome of process design, whether upgrading an existing plant or planning a greenfield operation, from the scoping stage right through to detailed design. Every aspect of the design can be validated through the use of DPS, for steady-state and dynamic performance criteria. Early adoption of Integrated Process Design and Pinch Analysis principals built into a DPS can unearth significant saving of materials, fresh water and energy, and will remain up to date as new processes and utilities are engineered and added to the site and DPS. A validated and up to date DPS can form the launching point of all future process design and optimization projects, ensuring that new upgrade or expansion projects integrate seamlessly with those that have already been implemented. Dynamic Data Reconciliation (DDR) can be applied to a DPS to validate information that is coming from an existing plant and ensure that engineers start future design projects with an accurate and valid plant model.


The ongoing task of process optimization is made easier and more constructive with the aid of Dynamic Process Simulation (DPS). Pumping performance, buffer storage times, redundancy systems, product changes and CIP cycles, decaying heat exchange coefficients, seasonal effects on the plant or the feedstock and many more dynamic effects can all be modeled and built into production schedule optimization or plant upgrade projects. How will my water saving projects affect the heat balance around my plant? If I debottleneck my process at point A then where will the new bottleneck be and will it be in a process or utility limitation? Is it possible to increase production while maintaining or even decreasing water and energy use at my site? What is the real cost of production across all product lines and how does a schedule change affect this cost and my marginal utility costs? A validated DPS can help to answer these questions and can even go on to form the backbone of an operator training platform as well.


The well-worn phrase “A picture tells a thousand words” has never been so true as when it is applied to engineering projects. Whether gathered around PFD or P&ID or observing DCS operator screens you cannot beat graphical display of information for pure clarity and ease of communicating complex ideas. Dynamic Process Simulation (DPS) brings together the clarity gained from colorful, animated pictures with the raw power of a mass and energy model of the processes on display. Early adoption of DPS in the project cycle facilitates strong, clear communication between all project stakeholders around a single visual tool. From the design desk to the board room and on to the operator training facility there is a single graphical engineering tool aggregating all of the quality and ingenuity that has gone into a project and making it accessible to everyone involved.
