Q: What kind of UniSim Design models can be used in UniSim Optimization Suite?A: Any steady-state UniSim Design model can be used with UniSim.
Q: Where has UniSim Optimization Suite Technology been implemented and what were the results? A: Although UniSim Optimization is a new product, the technology components of UniSim Optimization have been used extensively on-line. For example, Profit Bridge technology has been installed in more than 15 installations worldwide since 1998 including ethylene and FCCU applications.
Q: Can I use my existing HYSYS steady-state models in UniSim Optimization Suite?A: Yes, as long as the appropriate licensing is in place to use the model on-line for optimization.
Q: What is the payback time on a typical UniSim Optimization Suite project? A: A typical UniSim Optimization Suite project will have a payback time of less than six months.
Q: How do I know if there are enough benefits to justify a UniSim Optimization Suite project? A: There are a number of ways to estimate the benefits of UniSim Optimization. The first way is to estimate the benefits as 25% of what has been achieved with advanced control. Additionally, there are some typical benefits for standard refining units. Finally, a benefit study can be undertaken in which the UniSim model of the process (supplied by the customer) is exercised over the expected operating region, and the non-linear behaviour is noted to estimate the benefits of non-linear optimization and control.
Q: Can UniSim Optimization be used with other vendors’ APC solutions? A: Sometimes. Only when ProfitMax is used for optimization can other vendors’ APC solutions be used.
Q: Can UniSim Optimization be used with other vendors’ DCS systems? A: Yes, as long as Profit Controller/Profit Optimizer is being used on these systems when Profit Bridge is being implemented.
Q: What hardware is required for UniSim Optimization Suite?A: UniSim Optimization runs on any NT node with a Pentium III or higher processor.
