Abstract

This chapter will discuss the impact of trace metals in kraft cooking and brownstock washing Although numerous trace metals are present, calcium tends to be the main concern because it is present at higher concentration and is the source of most scale problems encountered in mills. Calcium Will also be the principal focus of this chapter. Other trace metals create management concerns in mills, but generally not within the brownstock washing system and cannot be effectively addressed Within that system.
