Dynamic Column with Control Systems<\/figcaption><\/figure>\n

CHEMCAD Dynamics is a remarkable tool for operator training. The example shown is a distillation column that looks like a Piping & Instrument Diagram.<\/h2>\n

Each control loop can be modified by changing the proportion, integral and derivative values. The model responds similarly to a plant distillation column.<\/p>\n

Liquid holdup in the column, heat exchangers and even piping can be added to the simulation so that the control loops respond just like the column in real time.<\/p>\n

Prior to a new technology being brought on line, operators can be trained on a PC running ChemCad Dynamics with a simulation of the new process.<\/p>\n

The operator being trained can see how the plant will respond to changes in level, flow and pressure set points on the various controllers.<\/p>\n

Note that this simulation looks more like a P&ID using International Society of Automation (ISA) Standards for the instrumentation and controls than a simulation or a Process Flow Diagram.<\/p>\n

Process failures can be created on the computer instead of the actual plant.<\/p>\n

Sometimes changes can be made to the control logic prior to startup from the information learned in the Dynamic simulation such as this one.<\/p>\n

CC-DCOLUMN is a module within the CHEMCAD system. As such, it uses all the features which are fundamental to the system. These include:<\/p>\n
