◙ Vol. Flowrate (L/h) The volumetric flowrate of cleaning agent used in the selected cleaning step.	6000.0	Positive
◙ Vol. Flowrate per Vessel’s Circumference (L/min-m) The volumetric flowrate of cleaning agent per vessel’s circumference used in the selected cleaning step.	35.0	Positive
◙ Vol. Flowrate per Vessel’s Internal Surface (L/m²-min) The volumetric flowrate of cleaning agent per vessel’s internal surface used in the selected cleaning step.	15.0	Positive
○ Flow Is Recirculated Check this box to account for recirculation of the flow of cleaning agent used in the selected cleaning step.	No	Yes/No
◙ Recirculation Times The number of times the flow of cleaning agent used in the selected cleaning step is recirculated.	1.0	Positive
◙ Once-Through Equivalent Time (min)	15.0	Positive
○ Remove Contents as Waste with Disposed Agent? Check this box to remove vessel contents as waste with disposed agent used in the selected cleaning step.	No	Yes/No
○ Waste Type Indicates the waste type used in the selected cleaning step. Click on the list box to bring up a list of available waste types in order to select one.	<none>	Any Waste Type
○ Waste Treatment Cost ($/kg) The cost of waste treatment per kg of waste material for the selected cleaning step.	0.0	Positive
○ Deposited to Storage Unit Select a Receiving storage unit to collect agent waste and contents, to track waste material. Once selected the Waste Type and Waste Treatment Cost take the values of the receiving unit. See Registered (in use) Material Storage Units for info on how to defined a Receiving Unit. By default the application will assign the “CIP Waste” storage unit which is created automatically for every new process model (see Special Purpose Receiving Units for CIP & SIP Waste).	<none>	Any Rec. SU
○ Link to template Checking this option will provide the user with the option to link this operation to a CIP Template predefined in the database.	No	Yes/No
○ CIP Skid Indicates the Auxiliary Equipment used to carry out this operation. See Auxiliary Equipment for information on how to define CIP Skids in the process.	<none>	User Defined
○ Include Use of Consumables Check this box to include the use of consumables by the CIP Skid. If the skid does not have any consumables specified this check box is hidden.	Yes	Yes/No
○ Setup Time The amount of time (per cycle) spent before each operation is carried in preparation for the actual execution of the operation. It may involve actions like cleaning, vacuuming, setting up of equipment, etc. which the user opted not to model explicitly.	0.0	Positive
● Process Time (min) The actual duration of the operation.	15.0	Positive

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Specification Choices / Comments

The following list describes the available specification choices in this tab; for more details on how these are implemented, see CIP: Modeling Calculations.

•Multiple CIP Steps...

You can have multiple CIP Steps in one CIP Operation. From the CIP list in the right pane select a CIP-Step and then set its properties. To add a new step click on the Add button. To remove a CIP step, select the step and click on the Delete button. To rename a step select the step and click on the Rename button. To insert a step above an existing step, click on the Insert button.

•Consumption Options...

There are 5 different options for consumption specification. The option for specifying the rate per circumference is only active if the operation takes place in a vertical vessel or another vessel that features a circular cross-sectional area. The option for specifying the rate per internal surface is only active if the operation takes place in a horizontal vessel.

•Recirculation Options...

The cleaning agent can be recirculated during a CIP step. Click on the ‘Flow is recirculated’ checkbox for cleaning agent recirculation. You can either set the recirculation times or the once through equivalent time.

•CIP Skid

A CIP skid can be either selected from a list predefined CIP skids by selecting it from the drop-down list or created by clicking on the Create new CIP Skid button . When creating a new CIP skid you will be presented with the Auxiliary Equipment Properties Dialog: Aux. Equipment Tab for: CIP Skid, SIP Panel and User-Defined Aux. Equipment Type dialog where you can enter the desired skid specifications. The selected skid properties may be viewed at any time by clicking on the view button .

•Sharing of CIP Skids...

When the same CIP skid is shared by multiple operations, the program makes sure that the processing times of those operations do not overlap.

•CIP Templates...

CIP operation templates can be predefined in the database (CIP Templates Databank), and all templates used in the process can be seen from the CIP Templates Currently Used in the Process dialog. Clicking on the button will give the user a dialog with a list of all available CIP templates that can be selected, and when clicking on the a new CIP template can be created from the current CIP specification in the CIP operation. The new CIP template will deposited in the database and also linked to the CIP operation (See Select a CIP Template from the Databank Dialog)

Select a CIP Template from the Databank Dialog

This interface is presented to the user after clicking on the select CIP template button from the CIP: Oper. Conds Tab. It displays all the available CIP templates in the databank, plus the templates that don’t exist in the database but are saved as part of the process, which have originated from a foreign CIP Databank.

This interface is the same as the previous, it is displayed when the user clicks on the create new CIP template button in the CIP: Oper. Conds Tab, but it allows the user to save a newly created CIP template or update an existing template in the databank, using the current CIP specification of the operation.
