The primary objective of this model is to calculate the amount of material used for cleaning a piece of equipment.
Available in almost every unit procedure.
The amount of material used for cleaning a piece of equipment is calculated based on one of the following specification options:
a) The cleaning agent rate (in L/min)
b) The agent’s specific volume (in L per equipment size); the units of ‘size’ are equipment specific (e.g., m3 for a vessel, m2 for a membrane filter, etc.).
c) The cleaning agent’s total volume (in L)
d) The cleaning agent’s rate per unit of circumference (L/min-m); this option is only available if the operation takes place in a vertical or horizontal vessel or other similar vessel that features a circular cross sectional area.
e) The cleaning agent’s rate per unit of internal surface (L/min-m2); this option is only available in horizontal and vertical vessels.
Please note that the ‘cleaning agent rate’ is the net flowrate and not the recirculating flowrate.
To represent a typical industrial CIP operation, you can use multiple steps for example washing with process water, rinsing with acidic solution, rinsing with caustic solution and rinsing with purified water. You can specify the different parameters for each cleaning step.
The duration of each step is user-specified. The cleaning agent can be selected from the list of registered pure components or stock mixtures. This operation is supposed to be used for cleaning empty equipment items. If material is present in the equipment, the program generates a warning. If the intended use is to remove material from a vessel using a solvent, you should use a Charge operation instead.
A CIP skid can be associated with this operation. If the same skid is utilized by other operations, the program makes sure that the processing times of those operations do not overlap.
