Recent developments in the technology of continuous pulping system

Abstract

In the recent past there have been several major developments in the technology of continuous pulping systems. These developments encompass improvements in chip presteaming. in continuous chip feeding equipment, and in the process chemistry and process configuration of the cooking vessel itself. The Diamondback (TM) Chip Bin is a new atmospheric pre-steaming reactor capable of uniformly pretreating incoming wood chips without the use of any moving components. The Lo-Level (TM) Feed System is a new chip feeding system which provides for increased capacity enhanced flexibility in equipment layout, and decreased capital and operating costs. Lo-Solids (R) Pulping is new pulping process which results in improved pulp quality and improved digester operation. Combined, these developments represent a significant advancement in the technology of kraft pulping.
