Initialising a Unit Procedure What a Unit Procedure? Initialising an Operation
What is a Unit Procedure? In the batch modeling mode, a Unit Procedure may consists of various Operations: Reactor procedure: feed charge, reaction, product withdraw, etc Filtration procedure: filtration, cake wash, CIP, etc In continuous modeling mode, a Unit Procedure= Unit Operation
Hierarchy in batch modeling Entire plant Procedure(s) level Operation(s) level The same for continuous process modeling
Function of each unit procedure Vessel Procedure (P-1): Acts as a batch reactor to carry out reaction: A + B C Heptane is used to dissolve components A & B, to aid separation in P-2 Plate and Frame Filtration (P-2): Component C is not dissolved in heptane, hence is filtered out by the filter cloth Heptane is used to wash out the trapped heptane ( and also the dissolved A & B) from the filter cake
Stream specification Heptane flow = 800 kg/batch Ingredient flow T, P = default Click to insert Heptane here
Set spec for Stream A & B Stream ID Component Amount (kg/batch) Temperature Pressure Heptane Heptane 800 A B A B 50 40 Default

A question to ponder Q: Why do we only specify the inlet stream?
Sequential modular approach Individual equipment blocks may require iterative solution algorithms Overall process solution is sequential & not iterative (Turton et al., 1998)
Adding operations to P-1 3 Charge operation (to charge A, B and heptane respectively) 1 React (Stoichiometric) operation (for reaction to be carried out) 1 Transfer Out operation (to deliver product to next unit)
Adding operations to P-1 Add new operation before the currently selected operation Add new operation at the end of the list
Initialising operations in P-1
Initialising CHARGE-1 Emission calculation (next slide ) Vol. flowrate =100 L/min Setup time = 5 min 800 kg heptane
Emission calculation lick to perform mission calculation OK, next operation (CHARGE-2) OK, previous Operation (none) Go to selected operation Previous operation (same tab none) Next operation (same tab)
Initialising CHARGE operation Operation Operating condition Emission CHARGE-1 Charge 800kg/batch of heptane using stream Heptane CHARGE-2 CHARGE-3 Setup time= 5 min Process time : 100L/min Charge 50 kg/batch of A (limiting component) using Stream A Setup time = 5min Process time: calculated based on 20 kg/min Charge 40/kg batch of B using Stream B (B is in excess) Setup time = 5 min Process time : calculated based on 20 kg/min Please complete the initialisation of CHARGE-2 & CHARGE-3 Perform heptane emission on this stream Nil
Initialising REACT-1 & TRANSFER-OUT-1 Operation Operating condition Volumes Reaction REACT-1 Final temp = 50 C TRANSFER- OUT-1 Heat transfer agent: steam Process time = 6 hour Leave other values as defaults Using stream Rxt out Duration: same as Cloth Filtration in P-2 (using Master-Slave Relationship) Max Allowable working/ vessel volume: 80 % Nil Extent of reaction = 95 % Reaction stoichiometry A + B C
Initilising REACT-1 in P-1 Final temp = 50 C Max allowable volume = 80 % Steam Process time = 6 h
Initialising REACT-1 in P-1 Edit reaction stoichiometry Rename reaction Reaction extent = 95 % Add reaction(s) OK, next operation (Transfer-out) Delete stoichiometry (when needed) Molar stoichiometry
Initialising Transfer Out Transfer out stream Click here to select Master-and-Slave to calculate duration To quit Vessel Procedure Select the Master Operation in Master Procedure Select the Master Procedure
Master-Slave Relationship Slave Master Master operation processing step that control the duration of another operation (slave) When simulation is executed, duration calculation for the slave operation will be bypassed (note: M&E balances affected), until the master operation is met Both master and slave operation may exist in the same procedure or in another procedure
Working session Let s try before we proceed further
Initialising operation for P-2 Cloth Filtration operation (by default, to filter product C) Cake Wash operation (to wash out left over trapped A & B in filter cake) Transfer Out operation (to deliver product)
Adding operations to P-2
Initialising operations for P-2
Initialising FILTER-1 Operation Operating condition Scheduling FILTER-1 Particulate component removal: 95% C (assuming that A & B are completely soluble in Heptane & C is virtually insoluble). LOD (loss on drying) = 35% (this value cause a portion of heptane & any soluble component to be held in the wet cake 65% is insoluble C). Filtrate stream: B + Heptane By default, first operation of any batch unit procedure is scheduled to start at the beginning of the batch Start time: relative to the START of TRANSFER-OUT-1 operation in P-1 procedure
Initialising FILTER-1 Scheduling C = 95% removal LOD = 35% By default Filtration will only start when product is transferred out from P1 Filtrate
Initialising CAKE-WASH-1 & TRANSFER-OUT-1 Operation CAKE- WASH-1 TRANSFER- OUT-1 Operation condition Wash In stream: Wash in Wash Out stream: Wash out Wash solvent: heptane (click on Composition, select Autoadjust, the program will estimate a value automatically) Wash time: 30 minutes Wash type: slurry (Note: A slurry wash will essentially dilute the soluble components trapped in the cake and remove most of them in the wash stream, whereas a displacement wash will remove the soluble components form the cake in a plug-flow fashion.) Transfer out using stream C Duration: calculated based on 10kg/min
