The Dilute is used to decrease the consistency or solids fraction of a stream by mixing it with a dilution stream. The Pulp_Inlet stream must contain non-zero solution and solid flows. The Liquor_Inlet stream, which contains dilution liquor, may contain a non- zero solid flow. The Liquor_Outlet (bypass liquor) stream is optional. If you don't connect a Liquor_Outlet the dilution stream is set to the dilution liquor required. The excess liquor flow is sent to the Liquor_Outlet. Any solid flow in the the Liquor_Inlet is sent to the Pulp_Outlet. What do you want to see? Data Description Equipment Properties Example Method&Equations Warnings Errors

Method&Equations

The Dilute calculates the total inlet solid flow in both inlets.

If the outlet consistency fraction is specified it calculates the required outlet liquor flow as:

       LIQFLO = (SOLFLO * (1.0 - CONS)) / CONS

where:

       LIQFLO is the required liquor flow

       SOLFLO is the total inlet solid flow

       CONS is outlet consistency you specify

If the outlet solids fraction is specified the required liquor is calculated as:

       LIQFLO = ( SOLFLO - SFRAC * TOTFLO ) / ( SFRAC - SFRAC2 )

where:

       SFRAC is the solids fraction desired

       TOTFLO is the total flow in the Pulp_Inlet

       SFRAC2 is the solids fraction in the Liquor_Inlet

The model also determines the dilution liquor required from the Liquor_Inlet as:

       REQLIQ = LIQFLO - LIQIN1

where:

       REQLIQ is the liquor required

       LIQIN1 is the liquor flow in the Liquor_Inlet

         If there is no Liquor_Outlet stream, the Liquor_Inlet's liquor flow is set to the amount required (REQLIQ in the above equation).
