ABSTRACT For the first time, the PPCHEM Seminar "Monitoring and Avoidance of Chemical Issues in Water-Steam Cycles" took place in Germany. This PPCHEM seminar series addresses important questions about the significance of water-steam chemistry, which parameters need to be measured, and how to effectively interpret and use the resulting data. It also highlights the risks […]
The German-Swiss Association for the Properties of Water and Steam (GSAPWS) e.V. held its annual general meeting and conference on March 5 and 6, 2026. This year, the events took place at Helmut Schmidt University in Hamburg, Germany.
ABSTRACT This article examines the spread of technical misconceptions on platforms such as LinkedIn regarding water-steam cycle chemistry in high-pressure utility systems. It focuses on the incorrect claim that alkalizing amines can replace ammonia for feedwater pH control, supported by a practical case history. While alkalizing amines have valid applications, their use as a direct […]

ABSTRACT This study investigates the root cause of performance deterioration in a demineralisation system, and ultimately identifies polymer fouling of the cation exchange resin as the primary issue. Detailed analysis revealed that surface fouling by cationic polymers selectively impaired the diffusion and exchange of divalent calcium ions due to steric exclusion effects, while monovalent sodium […]
