IPS Releases Dynsim 4.3

Dynamic Process Simulation Software Improves Design and Analysis

PLANO, TX--(Marketwire - September 17, 2008) - Invensys Process Systems (IPS), a global technology, software and consulting firm, today announced that it has released a new version of its Dynsim™ dynamic simulation program, used by chemical engineers to simulate industrial processes in the oil and gas processing, liquified natural gas, refining, petrochemical and chemical industries for design and operator training.

Version 4.3 of the Dynsim program includes improved features for distillation modeling, compressor modeling, process visualization and ease of use that allow design engineers to improve process designs and control systems, significantly reduce equipment capital costs and avoid startup delays of new facilities. The new features will provide more accurate simulators to train plant operators at new facilities and new plant operators to replenish a retiring workforce.

"The Dynsim solution is one of the only dynamic simulators in the market that can be used over an entire project lifecycle, from process engineering design to control system checkout to operator training," said Tobias Scheele, IPS Vice President of Advanced Applications. "Dynsim 4.3 is an example of our commitment to creating new, powerful solutions that meet the evolving needs of the industry, and we will continue to develop better software and technology that deliver significant value to our clients."

Version 4.3 of the Dynsim program includes improved distillation column modeling for more realistic operator training and rigorous column relief analysis. The program can be easily used to completely model process relief and flare systems from a typical distillation column relief source all the way to the flare tip. Visualization improvements allow dynamic plotting of column internal conditions to reveal what occurs during normal and transient operation, such as pressure relief. It can also be used to eliminate or reduce the cost of a relief and flare system expansion by providing a more accurate alternative to conventional design methods.

Version 4.3 also includes new features that more accurately model compressor systems for process design and control strategy validation. The Dynsim program is integrated with SimSci-Esscor's TRISIM Plus program to provide connections to Triconex's TriStation™ 1131control configuration tools for detailed checkout of turbomachinery controls. Improved visualization features allow dynamic plotting of the compressor operation on its performance curve. Additionally, the Dynsim program can validate the compressor protection control system designs and reduce the time required to commission the new controls in the field for an accelerated plant startup. Other visualization features in the Dynsim version 4.3 program include the plotting of temperature profiles in advanced heat exchange systems, such as a main cryogenic heat exchanger found in LNG liquefaction plants.
