Topics:
- Chemical Reaction Engineering and Reactor Design – examples
from pulping, bleaching and other bio derived chemical processes
- Solid-liquid separation processes – filtration,
thickening, sedimentation, settling
- Solid-solid separation processes – screening,
cleaning, centrifugal separation – examples from paper
manufacturing and wood composites manufacturing (screening fiber/fines,
oversize materials and classification)
- Transport processes through porous media -
fluid flow through porous media - examples from washing, chemical
recovery, waste treatment, sheet forming, pressing etc.; heat
and mass transfer into Veneer logs during impregnation, preservative
treatment of lumber and logs; other bio based materials manufacturing
processes
- Evaporation – heat and mass transfer – single
and multiple effect evaporators and process systems, vapor recompression – examples
from black liquor chemical recovery and other bio-based products
manufacturing
- Combustion – drying, pyrolysis, char
combustion – solid and semi-solid combustion – waste
heat boilers, chemical recover boilers - energy recovery; bio-derived
fuels (ethanol, diesel etc.)
- Mechanical treatment of bio-based materials – communition
(size reduction – materials to particles – chipping,
debarking), mechanical pulping, fiber refining, stock preparation
process systems, sawing, flaking, stranding, peeling, slicing,
peripheral milling (planing, shaping), grinding – abrasion,
sanding,
- Drying – heat and mass transfer, process
design, equipment design – examples from wood drying (lumber,
flake, strand, chip drying, veneer), paper drying etc.
- Bio-based Products Manufacturing Processes – Paper
machine design and operation – various machine designs,
characteristics, and operation; - wood products manufacturing
systems design and operation – wet process, high density
fiber board (Masonite), medium density fiber board (MDF); other
bio based materials manufacturing – PLA, PHB, Cellulose
Acetate etc.; finishing and converting – calendaring, super
calendaring, tempering
