TAPPI T618

Analysis of limestone, Test Method T 618 cm-24

Applicability: TAPPI T 618 cm-24 – Analysis of Limestone – is a standard that describes the chemical analytical methods used to determine the calcium carbonate (CaCO₃) content and related chemical characteristics of limestone used in the pulp and paper industry.

Purpose: TAPPI T 618 cm-24 provides standardized chemical methods for determining the composition and quality of limestone used in kraft pulp mill chemical recovery systems. Its primary purpose is to ensure that the limestone used to produce lime (CaO) in the causticizing/lime reburning cycle has the correct chemical characteristics for efficient kiln operation and high-quality lime production.
