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

 

Final Temperature (oC)
The final temperature of vessel contents after the end of the operation.

25.0

Positive

Heating Duty (kcal/h)
The heating duty of the heat transfer agent.

0.0

Positive

Cooling Duty (kcal/h)
The cooling duty of the heat transfer agent.

0.0

Positive

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

<Chilled Water>

Any Heat Transfer Agent

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

5.0

Positive

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

10.0

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)

Pressure Set by User?
Check this box to set the pressure.

No

Yes/No

Pressure (atm)
The operating pressure of the vessel.

1.0

Positive

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 the operation per volume.

0.0

Positive

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

0.0

Positive

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

0.0

Positive

Power Dissipation to Heat (%)
The percentage of total power that is dissipated to heat and raises the temperature of the material contained in the vessel.

100.0

[0,100]

Allow for Split After Storage

No

Yes/No

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 Continuous Storage: Modeling Calculations.

Pressure...

The pressure of the system, if not specified by the user, is set equal to the pressure of the previous operation.

Allow for Split After Storage...

If you check the option ‘Allow for a Split After Storage’ then the Split Tab becomes available. This tab allows you to specify either total flow or specific component splits to the various streams exiting the vessel.
