DESIGN & SIMULATED TEST: ROUND-UP
Chemical
process plant operators are in decline
PLANT TRAINING SIMULATOR TACKLES SKILLS SHORTAGE
I
n the oil, natural gas, petrochemical, chemical, and other industries, the number of skilled operators continues to
decline each year. As a result of the pressing need to train new operators, interest has grown in plant operator training systems. Omega Simulation was established in
April 1997, bringing together Yokogawa’s plant control systemknow-how andMitsui Chemicals’ process simulation technology. Yokogawa has an 85.1 per cent stake in this company, with the remainder held by Mitsui Chemicals. Omega Simulation’sOmegaLand
integrated dynamic simulation environment enables the construction of virtual plant models that can be used not only for the training of plant operators but also for the study and verification of chemical processes and the design of new processes. With the ability to precisely reproduce
plant operations based on the processes at actual plants, OmegaLand consists of the
36 /// Environmental Engineering /// April 2017
VisualModeler plant dynamic simulator and a variety of functionalmodules. These include a graphicmodule for the on-screen display of plant operations and a simulation controlmodule.With the assistance of an engineer, thesemodules can be combined to construct a systemthat meets the needs of each user. With this latest release, the user
interface has been updated to allow users to operate different functionalmodules using the same integrated environment. Previously, engineers had to launch multiple functionalmodules before they could carry out a task; with this new version, tasks can all be easily executed on a single screen. Operability has also been improved by standardising screen design based onWindows 7 andWindows 10. Previously, when building and tuning a
virtual plantmodel to reproduce the behaviour of a plant, engineers had to wait for the simulation to complete before modifying the program.With the new version, the simulation can be paused at any time if a problemis encountered with themodel; once the programismodified, the simulation can be continued. In addition, the graphics and instruction functions have beenmodified to improve operability.
ENGINEERING ANALYSIS FOR EVERYONE
W
hy does it still take a highly-trained expert to run an engineering analysis or computer simulation?
HBMPrenscia has developed Aqira, which allows engineers to gain faster results and more collaboration. Engineers canmanage analysis processes
and share themvia a web portal. Aqira uses a token-based licensing systemfor time- zone operations formore cost-effective global usage. It can run any configuration of nCode software for engineering tasks fromprocessingmeasured data to performing fatigue life prediction or acoustics and vibration analysis. Additionally, Aqira eliminates the need for local software installations because it runs nCode software via a web browser. Additional features include:
ability tomanage and share analytical processes via a web portal; scalable, server-based analysis; benefits of cost-effective deployment and licensing; and control and track licence token usage.
