Product Mix Design
This is used for arriving at various product mix which is feasible for given plant conditions. Before starting Product Mix Design, it is required that be done first. Product Mix Design will give the stream and plant parameters to be maintained for specified product mix.
Stream Details
This page displays the stream details and allows them to be copied into a text file or print them.
Stream Properties
This page will display physical properties of all the plant streams. All the displayed items could be saved into a text file or printed also.
Export Data
This is used to send the data to a text file to be used by AutoCAD for making Process Flow Diagram and Material Energy Diagrams.
Export PFD Data
Exports stream data in Process Flow Diagram format.
Export MED Data
Exports stream data in Material Energy Diagram format.
Convertor Module
This module pertains to the Convertor design and simulation for SO2 oxidation to SO3.
Convertor Editor
This will open the convertor editor if not already open otherwise switch to it.
Catalyst Loading
This will calculate the amount of catalyst required for specified conversion in each pass. Pressure drop also is calculated in each pass and can be seen by (Examining the stream details. :Stream Data)
Conversion Simulation
This will calculate the conversion possible in each pass for specified amount of catalyst loading in each pass. Pressure drop also is calculated in each pass and can be seen by Examining the stream details.
Absorbers
This module pertains to design/simulation of various absorption towers.
Packed Height Calculation
After entering all the data this is used to calculate the packed height required and pressure drop in packing.
Absorber performance simulation
For a specified amount of packed height this will give the outlet streams and pressure drop.
Concentration Profile
This will generate the data for concentration profile in the absorption tower along the height of packing.
Copy Stream
This copies the current stream onto the clipboard.
Cut Stream
This cuts the current stream and places it on the clipboard.
Paste Stream
This will insert the stream from clipboard at current place.
Mark as First Stream
Current stream is marked as first stream. This is used when marking streams for heat exchanger, absorber, heat balance, adding streams etc.
Mark as Second Stream
Current stream is marked as second stream. This stream is used as other stream for heat exchangers, adding streams etc.
Add Streams
Two marked streams are added and resulting stream placed at current cell.
Exchange
Two marked streams are exchanged.
Heat Balance
After marking first stream in a set of four streams for inlet, outlet of cold and hot fluids, this heat balance is done.
Saturation
This calculates the saturation vapour pressure of stream and pressure is set to that value.
Saturation Temperature
This calculates the saturation temperature of stream and temperature of stream is to that value.
Compute Temperature
This calculates the temperature of stream corresponding to the current enthalpy value of the stream.
Compute Enthalpy
This calculates the enthalpy of the stream at the current temperature.
Heat Balance
In the stream editor itself you can do the heat balance. For doing the heat balance you, place the 4 streams viz.
- Hot/cold inlet stream
- Hot/cold outlet stream
- Cold/hot inlet stream
- Cold/hot outlet stream in four subsequent rows
Then select the beginning row containing 4 streams. You can do heat balance of these 4 streams by pressing "H" button on tool bar or from pop-up menu. For doing the heat balance, leave the parameter to be calculated as zero e.g. if you want to calculate inlet or outlet temperature of any stream, then leave the temperature of that stream as zero. If you want to calculate flow rate then leave the flow rate of inlet stream (hot or cold) as zero. You can set the heat loss percent to be used from pop-up menu. Default value is set at 3%.
