The Society of Chemical Engineers, Japan recently announced the SCEJ
Awards for the fiscal 2002 and the Dynamic simulator Visual
Modeler developed and being sold by Omega Simulation Co., Ltd.
received the SCEJ Technology Award.
The Visual Modeler has made it possible to produce a
virtual plant representing a real one with complete fidelity which is
applicable to operator training and education, study of operating and
controlling methods, operation optimization and so forth. We would like to
express our gratitude to the Society of Chemical Engineers, Japan who has
highly evaluated our simulation technology that is all-Japanese and that
have produced many good results at home and abroad.
The dynamic simulator, Visual Modeler , is a
general-purpose simulator designed for a plant handling various chemicals
and petroleum. A plant model can be configured by arranging various
process units and instruments units on the PFD (process flow diagram) and
connecting them by material streams (piping) and data streams (signal
lines). The process units include, for example, a distillation tower, a
reactor, a heat exchanger, a valve, and a pump and the instrument units
include a flow meter, a thermometer, and a PID controller. As this model
is calculated every moment, the movement of a plant is simulated. Each
unit is modeled strictly on the basis of the principles of chemical
engineering and many units are calculated as a whole at high speed to
reproduce the plant movement with high fidelity and to realize a virtual
plant on a computer. This virtual plant has been put to diversified
practical uses as a simulator of high level application system (OmegaLand)
for operator training, process analysis and examination, education of
chemical process, tuning of control system, operation support and
optimization.
Unlike existing simulators for processes, the Visual Modeler is capable of executing real time simulation with complete fidelity of a
large plant which consists of more than 10,000 units including all devices
for startup/shutdown and safety necessary for operation. Moreover, it is
possible to simulate accurately in detail even when equipment is empty.
Since more than 200 standard units are contained, a plant can be easily
configured. For special units which cannot be covered by the standard
units, there is an expanding method to create custom-units. Thus, the Visual
Modeler has various unique features.
About 100 license of the Visual Modeler have already been
sold mainly in Japan and are well applied to business at enterprises and
researches at universities.
