Online measurements of Kraft pulping liquors have historically been a hurdle for the pulp processing industry. Traditional measurement techniques (i.e., conductivity, density, temperature and differential pressure) have only had moderate success due to scaling and fouling of their probes. Moreover, these devices lack chemical specificity. Until recently, the industry has accepted laboratory titrations as its choice method for complete liquor composition analysis.
Today, FITNIR Analyzers provides reliable, accurate and true measurements for the broadest set of liquor properties. With the ability to provide simultaneous measurements of multiple chemical properties, minimal sample preparation, and no plugging or fouling, FT-NIR is quickly becoming the technology of choice for superior causticizing efficiency.
