g. Once production is completed the products are then ready for distribution. A
distribution center normally consists of a small group of storage tanks, frequently
road, or rail; one or two small buildings to include offices, garages, workshops;
and frequently a large drive-in and turning space for road vehicles.
installations are normally situated in or around large residential or industrial
areas (Figure 2-49).
4. Additional chemical processing industries include cellulose pulp (paper)
production, ore concentration (magnesia from brines), soda ash, sulfuric acid,
chlorine, caustic soda, ammonia, alcohol, plastics, solvents, rubber, and
a. Cellulose pulp (paper) production flow (Figure 2-50).
The two most widely
used raw materials for the production of cellulose pulp are pulpwood and cotton.
(1) Cotton is moved from the warehouse to a fiber shredding and cleaning
process and then by conveyor direct to the digestion building. Pulpwood is moved
from open stockpiles by conveyors to the debarking equipment.
(2) The stripped logs are then moved by conveyor to the chipping building,
where they are reduced to chips; these may be stored in chip storage silos nearby.
