Advanced Process Control Business Unit
Hyperion’s Advanced Process Control (APC) Business Unit provides process control solutions to the process industries. APC engineers are based in Nicosia, Cyprus and work closely with Hyperion’s Client, AspenTech. Together, we design, build and install software-based, custom solutions for client plants in the Petroleum, Chemical and related industries. We use AspenTech's DMCplusTM, AspenWatchTM and AspenIQTTM software.
Our services help the client increase plant profitability by improving the way the process is controlled. This in turn improves product uniformity, maximizes throughput and minimizes the time of product grade changes.
The People
Hyperion’s Advanced Process Control (APC) Business Unit consists of highly trained Chemical and Electrical Engineers. Today, all APC engineers hold advanced degrees in Process Control or related technical areas. Newly hired engineers are trained thoroughly in the use of the software and gain expertise quickly by working under experienced, specialised professionals.
The Technology
Our advanced process control solutions use the fieldproven multivariable control algorithm of Dynamic Matrix Control (DMC) pioneered by Dr. Charles Cutler in 1979. The heart of the application is DMCplusTM, a model-based predictive controller, supplemented by two companion applications, AspenIQTM , and AspenWatchTM. Since its initial release, the product has been enhanced significantly to improve reliability, robustness, ease of use and range of application.
 Dynamic simulation capability with graphic and tabular interface allows APC engineers to test the configuration and predictions of a configured controller. This can be done prior to installation, during controller commissioning at the client plant sites or any other time.
DMCplusTM uses a time based step response model of the process to determine the best set of moves that keep the process at a given set of constraints determined by economics. It does this while dealing with disturbances, both measured and unmeasured. It is able to simultaneously manage multiple constraints and optimize an objective function based on economic targets, on-line or off-line. It is compatible with the leading Distributed Control Systems (DCS) and with automated plant optimization software such as AspenTech’s RTOptTM real time optimizer. Critical process properties that are not measured directly, such as feed composition, may be inferred from related process measurements such as temperature, pressure and flow. This is done by the AspenIQTM inferential property estimator.
 DMCplusTM offers a state of the art interface that allows construction of dynamic process models from collected on-line data for each pair of independent versus dependent variable in the design. Many special features allow fast and convenient data analysis such as data smoothing, curve transformations, seamless addition or exclusion of data blocks, seamless combination of model subsets into the overall model, and graphic comparison of predictions against real data, to mention a few.
