Sulphur gas analysis in the pulp and paper industry

Abstract

Various techniques of determining total reduced sulphur (TRS) gases that are emitted in the manufacture of pulp and paper, particularly in the kraft pulping process, are reviewed. Particular emphasis is placed on two types of popular TRS analyzers used in Canada, viz. coulometers and gas chromatographs, with a discussion on the automation of the latter. © 1988 Taylor & Francis Group, LLC.
