Characterization of Nonmicrobiological Paper Mill Deposits by Simultaneous TG-IR-MS.

Area of Science:

• Chemical Engineering
• Materials Science
• Analytical Chemistry

Background:

• Paper mill operations face persistent challenges with deposit formation and identification.
• Deposits, comprising non-fiber materials, accumulate in closed water systems, causing impurities and equipment contamination.
• Traditional analytical methods for pulp and paper process impurities include chromatography and spectroscopy.

Purpose of the Study:

• To introduce and evaluate simultaneous thermogravimetry-infrared-mass spectrometry (TG-IR-MS) as a novel technique for analyzing paper mill deposits.
• To demonstrate the efficacy of TG-IR-MS in rapidly identifying the sources of contaminants in paper mill systems.

Main Methods:

• Application of simultaneous thermogravimetry-infrared-mass spectrometry (TG-IR-MS) to mill deposit samples.
• Analysis of deposit composition and identification of contaminant origins.

Main Results:

• TG-IR-MS provides a rapid analytical approach for mill deposits.
• The technique enables swift identification of contaminant sources within the paper manufacturing process.

Conclusions:

• Simultaneous thermogravimetry-infrared-mass spectrometry (TG-IR-MS) is an effective and rapid tool for paper mill deposit analysis.
• This advanced analytical method aids in mitigating issues caused by impurities and contamination in paper production.
