Chien Hwa Chong About the book By table of contents Book description Chemical Engineering Process Simulation is ideal for students, early career researchers, and practitioners, as it guides you through chemical processes and unit operations using th This book will help you predict the characteristics of a process using mathematical models and computer-aided process simulation tools, as well as model and simulate process performance before detailed process design takes place. Content coverage includes steady and dynamic simulations, the similarities and differences between process simulators, an introduction to operating units, and convergence tips and tricks. You will also learn about the use of simulation for risk studies to enhance process resilience, fault finding in abnormal situations, and for training operators to control the process in difficult situations.
A mixer unit must be used. Physically, mixers for two streams and splitters to form two streams are normally pipe tees. For a mixer, it is best to have HYSYS take the outlet pressure as the minimum of inlet pressures although a side branch can provide suction, as in a jet pump.
Following is the procedure to produce a desired mixture from specified input streams. Select a Mixer and specify the compositions and properties of the input streams.
Then select the Balance logical operation. Double click on its icon on the pfd and specify the same input and exit streams as for the mixer. On Parameters select general. Then specify the desired composition and Simulation unisim of the exit stream.
HYSYS should do the heat and material balances required to give the unknown input stream flows, provided you have made the required number of specifications. HYSYS may not produce a satisfactory pfd, e. Show feed streams entering at the left and product streams exiting at the right, with the names of each prominently displayed so the viewer can readily see them.
If possible, as in Turtonput a stream table on the same page showing pressure, temperature, fraction vapor, total molar flow, component molar flows and any other vital information. You can use any bitmap bmp for a logo.
You can, for example, use the Clarkson University logo by going to http: Use the following procedure to change, for example, the stream page. This opens a new item in the top toolbar for the Workbook. Click on the Materials Streams tab.
Delete variables not wanted and add variables desired.
The following are recommended: Temperature, Pressure, Vapor fraction, Mass flow, Molar flow, and component molar flows. Alternately, Phase Component Molar Flows can be selected. If desired, change the name of an item by clicking on the left side of the cell with that name. Format the significant figures and put the variables in the order desired.
Return to the Workbook and right-click on the top blue bar of the Workbook window.
Select Print Datasheet and Preview to make certain this page will appear as desired when printed.Simulation Environment of UniSim Design R The first task in the simulation environment is to add one or moor feeding streams.
In this particular case there is only one feed to the column. To simplify the flowsheet some of the. preceding vessels as tanks, mixers, heaters are disregarded and only one stream with the requested parameters is.

The complete dynamic simulation was done in UniSim Design & UniSim Operations. The project involved development of new simulation modules within UniSim by timberdesignmag.comus dynamic testing of the newly developed modules was a major challenge besides volume of the process modeling.
