Because of the organic nature and the natural foaming characteristics
of kraft mill effluents, it was decided to investigate the
feasibility of using foam separation as a method of treatment. The
treatment efficiency was evaluated by BOD and COD reductions as
well as the decrease in toxicity to marine life....
Combustion properties of kraft black liquor solids were studied using a laminar entrained flow reactor. The tendency of black liquors to release fume (compounds containing Na⁺, K⁺, Cl⁻, SO₄²⁻, SO₃²⁻, S₂0₃²⁻ and C0₃²⁻) during combustion were observed at 1000°C. Black liquor solids with a size fraction of 63 to 100...
"The purpose of this report is to evaluate alternate engineering plans for the disposal of wastes from a kraft process pulp and paper mill located at Toledo, Oregon. These alternatives have been evaluated from the standpoint of estimated annual cost and estimated resulting pollution of Yaquina Estuary in order to...
Formaldehyde-based adhesives such as urea-formaldehyde (UF), phenol-formaldehyde (PF) are widely applied in wood-based composite industry. However, these adhesives are all petrochemical-based and could not sustain in a long term due to a limited reserve of oil and natural gas. Moreover, these adhesives emit carcinogenic formaldehyde in the production or use...
Particleboard is widely used for making bookshelf, furniture, cabinets and many other interior products. At present, particleboard is mainly produced with wood particles and urea-formaldehyde (UF) resins. The emission of carcinogenic formaldehyde in the production and use of particleboard has generated an urgent need for development of a formaldehyde-free wood...
