Course Outcomes Upon successful completion of this course, students should be able to:
1.
Perform a material balance on a typical wood yard.
2.
Perform material and energy balances for a kraft batch digester/blow tank system. Calculate steam
requirements, flash steam production and cold blow black liquor requirements.
3.
Calculate the H-factor given digester operating parameter information.
4.
Perform material and energy balances for a Kamyr hydraulic digester. Calculate various steam
requirements, black liquor flows and %solids in the liquor to evaporator, flash steam produced and all
process flows around the digester.
5.
Perform liquor and dissolved solid balances on vacuum drum washer and calculate washer loss.
6.
Perform material balances on a Tomlinson furnace, calculate air supplied by an F.D. fan and the I.D. fan
load.
7.
Perform material balances on the causticizing section; use a given causticizing efficiency to calculate
slaker flow, white liquor clarifier underflow and overflow streams.
8.
Perform material balances on a lime kiln.
9.
Calculate furnish flows in the stock preparation/approach flow section of a paper machine.
10.
Perform material balances on a Fourdrinier machine.
11.
Calculate single pass retention and overall retention of fillers and fibers.
12.
Perform dryer material and energy balances. Calculate drying rates and thermal efficiencies.
