Use this operation to simulate cake drying in a Nutsche filter.
● Nutsche Filtration Procedure
The material balances for the drying operation are based on the evaporation percentage of volatile components, which are either specified by the user or calculated based on final LOD. If an inert gas is used to facilitate drying, its relative flowrate (kg of gas per kg of solvent evaporated) must be specified by the user. The drying time is either specified by the user or calculated based on the evaporation rate (kg evap./m2-h). The Final Solids temperature simply determines the temperature of the dried cake without having any impact on the energy balance. The heating required for drying is calculated by multiplying the specific heating for drying by the total amount of evaporated solvents. The calculated heating requirement is drawn from the heating agent of choice.
To account for any power requirement for agitation, vacuum, etc. the user can provide a value for the specific power requirement in kW per m2 of filter area or simply specify the power consumed.
