1 Basics of Kraft Pulping & Recovery Process Art J. Ragauskas Institute of Paper Science and Technology Georgia Institute of Technology

2 Outline History Goals Process Overview Kraft Pulping Process Kraft Recovery Power Plant Caustic Plant

3 History Soda pulping process patented, Soda recovery via incineration patented, First successful soda mill, Kraft pulping process patented by Dahl, First commercially viable kraft mill, Sweden, Kraft recovery furnace, 1930 s.

4 Kraft Pulping and Recovery: Overall Objectives Chemical convert wood into cellulosic pulp High quality, strong pulp for papermaking Operate safely Minimize impacts on air and water Satisfy customer needs Maximum product quality Minimize cost

5 Kraft Pulping Objectives Use chemicals, heat, pressure to liberate fibers. Operate safely. Minimize impacts on air and water. Satisfy customer needs - maximum product quality. Minimize cost.

6 Kraft Recovery Objective Concentrate and burn black liquor. Provide energy produced from organics. Provide partially reconstituted pulping chemicals. Operate safely. Minimize impacts on air and water. Satisfy customer needs, product quality. Minimize cost.

7 Kraft Caustic Plant Objective Final step in reconstituting pulping chemicals. Provides fresh cooking liquor. Regenerates lime from lime mud. Operate safely. Minimize impacts on air and water. Satisfy customer needs, product quality. Minimize cost.
