Column AP Control Via Heat to Reboiler

Before looking at the overall control scheme, let us discuss what is meant by the column impedance. [Pg.420]

Signal flow diagram for column pressure control via manipulation of condenser cooling water [Pg.421]

Relationship Between Boilup and Column Pressure Drop [Pg.422]

So far we have assumed that there is negligible lag in vapor flow between adjacent trays. This means that we treat the acoustic impedance Z oi between the bottom and top trays as a pure resistance approximately equal to [Pg.422]

If the individual RC sections are equivalent, or nearly so, then the impedance looking up from the reboiler is approximately  [Pg.422]
