Dynamic simulation is an extension of steady-state process simulation whereby time-dependence is built into the models via derivative terms i.e. accumulation of mass and energy. The advent of dynamic simulation means that the time-dependent description, prediction and control of real processes in real time has become possible.
This is a list of software used to simulate the material and energy balances of chemical process plants. Applications for this include design studies, engineering studies, design audits, debottlenecking studies, control system check-out, process simulation, dynamic simulation, operator training simulators, pipeline management systems, production management systems, digital twins.
HYSYS is used extensively in industry and academia for steady-state and dynamic simulation, process design, performance modeling, and optimization. [3] [4] Etymology
Chemical process modeling is a computer modeling technique used in chemical engineering process design. It typically involves using purpose-built software to define a system of interconnected components, [ 1 ] which are then solved so that the steady-state or dynamic behavior of the system can be predicted.
Steady state determination is an important topic, because many design specifications of electronic systems are given in terms of the steady-state characteristics. Periodic steady-state solution is also a prerequisite for small signal dynamic modeling. Steady-state analysis is therefore an indispensable component of the design process.
The COCO Simulator is a free-of-charge, non-commercial, graphical, modular and CAPE-OPEN compliant, steady-state, sequential simulation process modeling environment. It was originally intended as a test environment for CAPE-OPEN modeling tools but now provides free chemical process simulation for students.
It can perform steady state mass and energy balance calculations for modeling, simulating and optimizing continuous processes. [4] [5] ROMeo 6.0 has been released with increased access to native Refinery Process Models based on technology from ExxonMobil. From ROMeo 7.0, ROMeo changed from 32 bit to 64bit.
DWSIM is an open-source CAPE-OPEN compliant chemical process simulator for Windows, Linux and macOS.DWSIM is built on top of the Microsoft .NET and Mono Platforms and features a graphical user interface (GUI), advanced thermodynamics calculations, reactions support and petroleum characterization / hypothetical component generation tools.
