Variable Definitions, Ranges and Default Values

The following table shows a brief description of the variables appearing in this tab. The table also displays their default values and their generally acceptable range:

Variable

Default Value

Range

 

Exit Temp. (oC)
The final temperature of vessel contents after the end of the operation.

20.0

Positive

Heating Duty (kcal/h)
The heat transfer rate of the heating agent, if a heating agent is used.

0.0

Positive

Cooling Duty (kcal/h)
The heat transfer rate of the cooling agent, if a cooling agent is used.

0.0

Positive

Heat Transfer Agent Name
Indicates the heat transfer agent used for the operation. Click on the list box to bring up a list of available heat transfer agents in order to select one.

<Steam>

Any Heat Transfer Agent

Inlet Temp. (oC)
The inlet temperature of the heat transfer agent.

152.0

Positive

Outlet Temp. (oC)
The outlet temperature of the heat transfer agent.

152.0

Positive

Rate (kg/h)
The mass flow rate of the heat transfer agent.

0.0

Positive

Heat Transfer Efficiency(%)
The heat transfer agent efficiency. If the value is lower than 100% then an increased heat transfer agent amount will be calculated by the program to satisfy the required duty.

100.0

[0,100)

Excess Neutralizing Agent Set by User

Yes

Yes/No

Inlet Stream
Indicates the input port that is connected to the neutralizing agent stream. If an input stream is already present at the selected port, then the button next to the selection is active. Click on the button to bring up the attached stream’s simulation dialog in order to provide its composition.

<None>

Dedicated Input Port

Excess Amount (%)

0-100

Agent Component
Indicates the pure component that is selected as the excess neutralizing agent. Click on the list box to bring up a list of registered stock mixtures or pure components in order to select one.

<none>

Any Pure Component

Power Type
Indicates the power type that is used by the operation. Click on the list box to bring up a list of available power types in order to select one.

<Std Power>

Any Power Type

Specific Power (Per Volume) (kW/m3)
The power consumed for agitation per volume of material.

0.1

Positive

Total Power (kW)
The total power consumed for agitation (per cycle).

0.0

Positive

Power Per Unit (kW)
The power consumed for agitation per equipment unit.

0.0

Positive

Power Dissipation to Heat (%)
The percentage of total power consumed for this operation that turns into heat, thereby raising the temperature of the material contained in the equipment.

100.0
