TAPPI T 240 Pulp consistency

Standard:  

TAPPI

Method:

TAPPI T 240

Title:

Consistency (concentration) of pulp suspensions

Scope

TAPPI T 240 Pulp consistency describes the measurement of pulp consistency (concentration) of aqueous fiber suspensions. The method applies to most pulps sampled from different process points in a pulp or paper mill. The method is applicable to pulps with up to 25% consistency.

Summary

A known weight of pulp suspension is filtered in a Büchner funnel. Fibers and other suspended matter are retained on an oven dried, pre-weighed filter paper. After drying to constant weight at 105 ± 3°C, the oven-dry weight of the retained matter is determined and calculated as the percentage of original pulp suspension weight.

Significance

Determination of pulp consistency is the starting point for the quantitative analysis of many other pulp characteristics. Furthermore, it provides the basis for mass balance and yield evaluation in a pulp and paper mill.
