Alkaline pulping : deadload reduction studies in chemical recovery system
(Georgia Institute of Technology, 2004-12-02)
The kraft pulping process has been known for decades. The focus in kraft pulping has always been on better operation of the chemical recovery system. One of the targets is on deadload (sodium sulfate (Na2SO4) and sodium ...
Gasification of Black Liquor with the Addition of Secondary Sludge
(Georgia Institute of Technology, 2002-04-15)
The effects of secondary sludge addition on black liquor gasification were studied. Additions of 0, 5, 10, and 15% secondary sludge solids to hardwood black liquor solids were considered. Gasification temperatures were ...
Kinetics of Ba(OH)₂ Reaction with Na₂CO₃ and Na₂SO₄ & Particle Separation Characteristics from White Liquor
(Georgia Institute of Technology, 2003-04-16)
The purpose of this study is to determining the feasibility of replacing causticizing (calcium based reactions and precipitate) with bausticizing (barium based reactions and precipitates). Bausticizing is not limited by ...
Determination of Reaction Kinetics of Barium Sulfide with Sodium Carbonate and Sodium Sulfate to Reduce Deadload in the Recovery Cycle
(Georgia Institute of Technology, 2004-04-15)
The following study deals with the characteristics of the reaction to form BaSO₄ and BaCO₃ from Na₂SO₄ and Na₂CO₃, respectively, using BaS as the other reactant. These reactions would theoretically increase the efficiency ...
Kinetics of the Titanate Causticization Reactions in a Potassium-Based Process
(Georgia Institute of Technology, 2004-04-16)
The objective of this study was to model the kinetics of direct causticization of potassium-based chemical using titanium dioxide, TiO₂. The starting materials were K₂CO₃ and TiO₂. Potassium chemical was used because there ...
