Drip
Percolation Pulping with Aqueous and Aqueous Organic
Ammonia and
Environment-Oriented and Conserving Technology
by V. S. Krotov
An outline of a new technology developed in the
A
new technology of pulping based on drip percolation using the liquid recovered
from a spent solution is discussed. In this technology, one closed unit can
integrate all the major processes of pulp production including raw material
impregnation and cooking, stock washing and dewatering, recovery of the liquid
fraction of a spent solution, collection and utilization of dirty condensates,
utilization of secondary steam and condensate heat, and collection and removal
of non-condensable gases without air entrainment with a view of their
neutralizing or utilizing.
