Project Location

A number of Digestion projects are available, these are stored at:
..\SysCAD92\Examples\SS_Alumina\Digestion Example.spf
..\SysCAD92\Examples\SS_Alumina\Digestion with Tube Digestor Example.spf

Brief Description

Project Digestion Example:

  • The digestion reaction assumed to only occurs at the digestor.
  • Steam is directly added to the digestor.
  • Heaters used are Shell&Tube heat exchangers.
  • The digestion circuit consist of 10 flash stages. Flash Vapour are sent to shell and tube heaters where they are fully condensed. The condensate is then reflashed to the next stage's pressure. The last condensate pot is modelled as a tank, as no flash will occur there.
  • Two controllers are set up in the project, 1) to control the steam addition to maintain the Digestor temperature. 2) To adjust the bauxite charge to maintain a user defined DBO A/C ratio.
  • Each set of Flash Tank - Heat Exchanger - Condensate Pot will form a Flash Train where the unit operations will operate at the same pressure, the pressure of the flash train will be determined by SysCAD based on the heater performance.
  • The flash Tank/Heat Exchanger/condensate pot set may be turned offline/off to allow the model be run with fewer flash stages for feasibility analysis.

Falling Film Evaporation Project

Project Location

This is a Steady State project and is stored at:
..\SysCAD92\Examples\SS_Alumina\Falling Film Evaporation Example.spf

Features demonstrated

  1. Shows how to set up a multistage Falling Film Evaporator trains.
  2. Shows how to set up PID controls to balance the pressure in the circuit.

  • Heat transfer coefficient and area are specified for all the evaporators.
  • Recirculation flows are set up for the evaporators.
  • The Falling Film Evaporator (FFE) unit is not included in the suite of flashing train models, therefore, SysCAD will NOT auto balance the pressures in this circuit. To balance the pressures, the project used a series of PID controllers to fine tune the pressure requirements in the various FFE units.
  • The Flash Tank pressures are set using the PGM file.


Precipitation Projects

Project Location

Two Precipitaion projects are available, these are stored at:
..\SysCAD92\Examples\SS_Alumina\Precipitation Example.spf

  4. Shows the use of integrated coolers with the precipitator in the Precipitation with Cooling Example.
  5. Shows the use of Specific Surface Area (SSA) with an average Seed Diameter for Fine Seed and Coarse Seed Charge.

Brief Description

Projects Precipitation

The precipitation circuit is set up as follows:

  • Three stages of Agglomeration Tanks with Fine Seed Charge
  • Seven Stages of Growth Tanks with Coarse Seed Charge
  • Last Precipitator Pump off goes into CL_1, where a product stream is drawn off.
  • The overflow from CL_1 goes into CS_classification, the underflow feeds the growth tank as Coarse Seed.
  • The overflow from CS_classification goes to FS_Classification, the underflow feeds the Agglomeration tank as Fine Seed. The overflow then becomes the spent liquor and returns to the circuit.

Important Settings for the Precipitation Circuit:

  • Tank Size should be specified for residence time calculation
  • Growth Method for hydrate seed must be specified via 1) Fixed rate 2) White-Bateman method 3) SSA Yield Method. If using methods 2) & 3), the growth method constants must be tuned to achieve the correct yield. The constants can be changed in the PGM file (Precipitation_PGM)
  • Bound Soda can be specified via 1) fixed % 2) original method 3) hunter method.
  • Cooling can be achieved via 1) fixed temperature drop 2) internal cooling 3) external cooling. The temperature plays an important part in the precipitator yield. So a change of temperature could greatly affect the result.
  • Seed charge P_17 (Fine Seed) and P_14 (Coarse Seed) have the Specific Surface Area / Average Seed Diameter data defined. These can be found on the last Qi Tab of the pipe. The average Seed diameter for FS and CS can be changed in the PGM file (Precipitation_PGM)
  • Optional Reactions - The hydrate precipitation and Soda co-precipitation reactions are built into the Precipitation unit, no extra reactions are needed in this example.
  • Optional Evaporation Rate can use specified

Using Specific Surface Area (SSA) Functionality:

  1. User must select this option in the configuration file. During Edit Project Configuration Step 1, select SizeDst1.dll|Specie Qualities|SpecificSurfaceArea.
  2. In the SysCAD project, on the Feeder or Pipe Qi Tab (Note, pipe must not be a simply pipe), where the SSA must be defined, under Qualities, select SzSSAct - Create.
  3. Under SSA section on the Last Tab of Content (for Feeder) or Last Tab of Qi (for Pipes), define the SAM or D and the Solid that contains the SSA data, in this case Al[OH]3(s). NOTE to define D, user must select the SetDiameter tick box.

  • Boiler: a single boiler is modelled with a user defined BFW flow, user can specify the Final T&P, Blowdown % and boiler efficiency. Based on the user defined parameters, SysCAD calculated the required heat for boiling and superheating the steam as well as the fuel energy requirements.
  • Combustion: The total combustion reaction energy should be equal to the required fuel energy calculated by the boiler. A PID controller measures this and adjusts the Fuel input to achieve the required energy.
  • Excess Air is also modelled and it's addition controlled by a PID controller. Air passes a preheater exchanging heat with the flue gas.

  • Combustion: The energy from the actual combustion reactions is used to provide energy to the Calciner to heat up the mixture.


Command Script Example

Project Location

This is a Steady State project and is stored at:
..\SysCAD92\Examples\SS_General\Command Script Example.spf


Features demonstrated

A simple project showing how to use command script file to complete sensitivity analysis.

  1. Shows the completion of sensitivity analysis via Excel reports.
  2. Shows the completion of sensitivity analysis via GetTagList and SetTagList.


Brief Description

(A) Using Command Script file with the Excel Report.

Step 1: Create the SysCAD project, make sure the project is solved.
Step 2: Set up an excel report for the sensitivity analysis. (See the Test Cases.xls included in the project.)
The Example Report is set up to run sensitivity for Heat Exchanger that is used to cool a process stream.
  1. Run the model with a number of values for the Heat Transfer Coefficient (HTC) to emulate scaling in the unit.
  2. Run the model with a number of values for the Cooling Water temperature to determine the effect of CW temperature on flow requirements.
Step 3: Set up a command script file to include all the commands to run the sensitivity analysis. (See the UsingExcelReport.ssc included in the project)
Step 4: Run the command script file from SysCAD menu command Tools | Command Scripts..., select UsingExcelReport.ssc and press execute.

The advantage with using the Excel report is that the excel file can be set up with nice formatting, including charts for data analysis. The disadvantage with using the Excel report is that it can be quite slower especially when running a large number of cases.


(B) Using Command Script file with the SetTagList and GetTagList.

Step 1: Create the SysCAD project, make sure the project is solved.
Step 2: Insert unit operations Set Tag List and Get Tag List
Step 3: Create 2 csv files, one containing the User Defined values for the Set Tag List and another containing the results for the Get Tag List. (See GetTagList.csv and SetTagList.csv included in the project)
Step 4: Set up a command script file to include all the commands to run the sensitivity analysis. (See the UsingSetTagAndGetTagList.ssc included in the project)
Step 5: Run the command script file from SysCAD menu command Tools | Command Scripts..., select UsingSetTagAndGetTagList.ssc and press execute.

The advantage with using the SetTagList and GetTagList is that it is much faster when running large number of cases. The disadvantage with using this method is that the csv files do not support formatting.


Cooling Tower Project

Project Location

This is a Steady State project and is stored at:
..\SysCAD92\Examples\SS_General\Cooling Tower Example.spf

Features demonstrated

  1. A simple project showing how to set up a cooling tower with makeup and losses.
  2. Shows the estimate calculation for the air flows required.
  3. Shows the use of PGM file for side calculation.
  4. Shows the use of EHX to set various heat sinks.

Brief Description

  • The Project is set up as two separate sections, Cooling tower and Air flow estimate. The temperature of the cooling water is interlocked with the air temperature out. This is done via a EHX block in the Air_EHX stream, where the HeatTransfer available amount calculated in the cooling tower is pasted there. This transfer is done in the GC_1 PGM file.
  • When setting up the cooling tower, AirWetBulbT, ApproachT/KaVL and LG_Ratio are important parameters to consider. See Cooling_Tower for more information on the definition of these fields.
  • Water loss due to Drift, cycles and evaporation are incorporated into the cooling tower, the total water loss value can be used to set the water make up into the cooling tower. This is done in the GC_1 PGM file.
  • The cooling tower can estimate the required airflow needed to achieve the required cooling. This is presented in the cooling tower model under Air-Water Mixture estimates. In this project, an optional air flow stream is added to mix with the evaporated vapour to give a air-water mixture stream.


Counter Current Washer Project

Project Location

This is a Steady State project and is stored at:
..\SysCAD92\Examples\SS_General\Counter Current Washer Example.spf

Features demonstrated

  1. Shows how to set up a three stage counter current washer circuit using the CCWasher unit operations.
  2. Shows how to set up a three stage counter current washer circuit using the Washer unit operation.

Brief Description

  • The project shows three circuits built using the CCWasher and Washer unit operations. The aim of the sample project is to show the difference in the two unit operations and how to connect them based on user requirements.
  • The CCWasher unit operation allows the user to define the washing efficiency based on the Scandrett Efficiency. This unit operation also assumes NO solids in the overflow. The sample circuit can be found on the CCWasher.scg page.
  • The Washer unit operation calculated the washing efficiency based on a MIXING Efficiency. The Mixing Efficiency can be based on either washing bypass directly to the overflow OR liquid being trap by the mud in the underflow. User must make a decision on which mixing efficiency method to use before drawing the circuit as the connections made to the unit operation would be different.
  • The Washer Circuit.scg page shows two circuits, one based on wash bypass to O/F and the other liquid being trap in the mud.
  • The Washer Unit operation also shows the calculation of the scandrett efficieny, user may not specify a required scandrett efficiency directly from the unit, however, user can still achieve a certain scandrett efficiency if required by the use of a PID controller. (The use of PID controller is not demonstrated in this project.)


Demand Project

Project Location

This is a Steady State project and is stored at:
..\SysCAD92\Examples\SS_General\Demand Example.spf

Features demonstrated

  1. Demand in Pipes and Feeders.
  2. Using saturated and super-heated steam.
  3. Example Stream Report.xls

Brief Description

The project shows an overall view of steam usage in a plant.

  • The plant is supplied with a single source of super-heated steam.
  • The steam is used in the plant at three different pressures, all requiring saturated steam.
  • The saturation is carried out in ties with the amount of water added controlled by a PID Controller.
  • The steam requirement for each area of the plant is set in the Demand section of the pipe feeding the area.
  • A reaction block in each area condenses the steam to water while maintaining the temperature at a constant value. This emulates the conditions in the plant, where the energy from the condensation is taken up with heating requirements.
  • Condensate from the higher pressure and temperature steam is flashed to recover steam at the next lower temperature steam required. The steam recovered joins up with the fresh steam feed.
  • The General Controller sets the temperature and pressure of the feed steam, as well as the required pressures for the HP, MP and LP steam.

Flash Train Project

Project Location

This is a Steady State project and is stored at:
..\SysCAD92\Examples\SS_General\Flash Train Example.spf

Features demonstrated

  1. Setting up flash trains using Flash Tanks, Shell & Tube Heat Exchangers, Direct Contact Heater and Barometric Condensers.
  2. The flash train steam demand is based on Heater duty.
  3. Shell & Tube Exchangers must be operating in a Fully Condensing mode while in a flash train.
  4. If a tie is used to split flash vapour to other units of the Flash train, the Tie|SplitFlow option must be used. Also, the Tie|GM|Operation must be set at General mode for the unit operations to be included in the flash train.

Brief Description

FlashTrain Flowsheet:

  • Slurry is heated with Live steam prior to the flash stages, the hot flash vapour from the flash stages are being recycled to preheat the slurry. The barometric condenser is used to cool the last flash stage vapour.
  • The Live steam heater would require the HX|IgnoreAreaLimit be switched on if user is unsure of the heater area and would require all the steam added be condensed. If not, the heater will only condense what it can and the condensate will be in two-phase. This could potentially create a problem for the temperature controller if the heater area is too small to achieve the required temperature change.

FlashTrain2 Flowsheet:

  • This flowsheet demonstrates the flash vapour being used by three subsequent models. The Tie X_1 has the Split Flow switched on and the it is operating on General Operation mode with all outputs on Demand mode. This allows SysCAD to demand the correct flash vapour from the flash tank based on the heater duties.
  • The steam demand will pass through cross page connections as shown on steam supplied to ST_2.


Heat of Dilution Project

Project Location

This is a Steady State project and is stored at:
..\SysCAD92\Examples\SS_General\Heat of Dilution Example.spf

Features demonstrated

  1. Heat of Dilution changes the Temperature of the mixed stream.
  2. Adding Heat of Dilution data to the Specie database.
  3. Switch on the Phase Change functionality from View|PlantModel|Species|Equilibrium|PhaseChange@MF

Brief Description

This is a very simple project to show how heat of dilution will affect the temperature of a stream as the component composition changes.

  • A stream containing water and one containing concentrated acid 98.3% H2SO4(l) are mixed together to form H2SO4(aq) solution. With the Phase change function switched on, the H2SO4(l) automatically converts to H2SO4(aq) and the heat of dilution is released, resulting in a rise of temperature.
  • The stream is cooled to lower the temperature.
  • A diluted acid stream is added to further dilute the acid solution. A slight temperature increase is observed.
  • The stream is then sent to a reactor where some of the acid is used.
  • The reacted stream is sent to a flash tank, where water is evaporated and the mixture is slightly concentrated, the temperature decreases as the mixture is becoming more concentrated.

For more information on H2SO4, see Sulfuric Acid (H2SO4) in 9.2

  5. Example reporting file can also be found in the project - Report.xls.

Brief Description

  • This is a simple project demonstrating a very simplified High Pressure Leach Circuit, where the slurry is leached with acid at High Temperature. The leached slurry is then cooled in multistage flashing, the flash vapour is re-used to preheat the autoclave feed.


Smelter Project

  2. The use of Make Up Source and Make Up blocks
  3. The Use of Reaction Blocks
  4. the use of PID controllers

Brief Description

  • This is a very simplified model of a smelter section. The project was created based on Glogow 2 Copper Smelter, Poland, as described in Extraction Metallurgy 1985.
  • Copper concentrate is dried and fed into the furnace, where Cu is smelted and sent to Anode Refining. Heating Oil is used to provide energy to the smelter.
  • The main focus of this project is the simulation of the flash furnace. The Flash Furnace, being a complex unit operation, is very difficult to simulate as one unit operation. To overcome this, the flash furnace was broken down to three smaller sections, these are modeled as Reaction Shaft, Settler Section and uptake offgas.
  • Both the reaction shaft and Settler sections contain reactions.
  • The Settler section has multiple outlets, where the slag and metal and offgas are drawn out.
  • The slag is sent to an electric furnace to extract out more metal.
  • Energy is recovered from the offgas in the waste heat boiler (modelled as Shell and tube heat exchanger in the fully evaporating mode).
  • Fines in the offgas is filtered out and returned to the Furnace.

  3. Switch on the Solubility functionality from View|PlantModel|Species|Equilibrium|Solubility

Brief Description

This is a very simple project to show how solubility data will affect a specie as temperature changes.

  • A stream containing water and one containing salt are mixed together and the salt dissolves to form a saturated solution.
  • The saturated stream is heated and further salt dissolves.
  • An unsaturated brine stream is added to the heated stream, and the final stream is saturated at a lower temperature.
  • The stream is sent to a flash tank, where water is evaporated and the mixture cooled. Some of the aqueous salt crystallizes out of solution.


Solvent Extraction Project

  5. Example Report.xls

Brief Description

  • Pregnant leach solution is passed through 2 extraction stages where valuable metals are extracted using organic.
  • The Extraction stage (Extraction_1) shows the use of isotherm. The isotherm is entered into the access window manually to represent the extraction rate for the first reaction, in this case, CuSO4(aq). When the isotherm is in use, the reaction extent for the first reaction is set from the isotherm.
  • The loaded organic is then stripped with an acidic solution in 2 stages to recovery the metal to the aqueous phase.
  • The Stripping stage (Stripping_2) shows the use of isotherm. The isotherm is entered into the access window manually to represent the stripping rate for the first reaction, in this case, R2Cu(o). When the isotherm is in use, the reaction extent for the first reaction is set from the isotherm.
  • The stripped solution is then sent to electrowinning to recover the metal and regenerate some acid to be used as the stripping solution.
  • Two Make up sources and make up blocks are used in the Loaded Organic Tank to
    1. maintain a required organic flow for the circuit.
    2. add in enough extractant to give the organic stream the correct composition.
  • Two Make up sources and make up blocks are used in the Spent Electrolyte Tank to
    1. maintain a required aqueous flow for the circuit (based on a required organic/aqueous ratio set by the PID controller for stripping_1 stage. In this case, it is 1:1 volume based.)
    2. maintain the correct acid concentration.
  • The bleed of electrolyte is done via the filter.
  • The bleed of organic is done via Crude removal.
