17novAll Day19PPCHEM Seminar & Forum South Africa 2026Plant Chemistry in Cycling Plants – A Major ChallengeThe Capital Menlyn Maine Hotel, 194 Bancor Ave, Waterkloof Glen, 0010 Pretoria, South Africa

Content

- Nowadays, countless power stations are forced into cycling operation as a result of the impact of renewables on the power market.
- Certain installations, such as concentrated solar plants, are in cycling mode simply due to their nature.
- Furthermore, industrial plants often operate in heavy cycling mode due to rapid and spontaneous changes in steam demand (e.g. paper mills).
- The consequences for the overall chemistry of these installations are significant and cannot be compared to those of a constant, steady load operation.
- These challenges affect not only the chemistry within the steam-water cycle, but also the daily routine operation, sampling/sampling systems, monitoring equipment, and, last but not least, the proper control of dosing for chemical treatment.
- This conference will introduce and discuss the major impacts, as well as demonstrate solutions and strategies.
- The PPCHEM Seminar & Forum South Africa 2026 will commence with a one‑day Power Cycle Instrumentation Seminar, followed by a two‑day Power Plant Chemistry Forum.

25mayAll Day26PPCHEM SCHULUNG SCHWEIZ 2027Grundlagen der Chemie in Wasser-Dampf-KreisläufenSwan Analytische Instrumente AG, Studbachstrasse 13, 8340 Hinwil

Content

Die zweitägige Schulung in den Grundlagen der Chemie in Wasser-Dampf-Kreisläufen. Geeignet für Betriebspersonal von Industrieanlagen, Kehrichtverbrennern und Fernwärmerversorgern.
Jetzt in der Schweiz – Wissen kompakt vermittelt!

Unabhängig von der Grösse, der Bauart des Kraftwerks oder ob es sich um ein Industriekraftwerk oder eine reine Stromerzeugungs-anlage handelt, spielt die Chemie im Wasser-Dampf-Kreislauf eine wichtige Rolle.
Eine korrekte und präzise Kontrolle der Chemie in den verschiedenen Prozessen und Systemen ist daher von entscheidender Bedeutung.
Verunreinigungen und Abweichungen von den empfohlenen chemischen Betriebswerten müssen schnell und sicher erkannt werden.
Welche Bedeutung spielt die Chemie im Wasser-Dampf-Kreislauf eines Kraftwerks (Stromerzeugung, Prozessdampfversorgung, Industriekraftwerk usw.)? Ist das nur ein kleines Problem oder kann es teure und empfindliche Auswirkungen haben?
Welche Parameter sollten wo und wie und warum gemessen werden?
Wie nutze ich die chemischen Daten, um «meine» Anlage sicher und wirtschaftlich zu betreiben?
Was kann passieren, wenn chemische Parameter aus dem Ruder laufen, und wie reagiert man am besten?
Welche Schäden lassen sich mit einer guten Instrumentierung verhindern?

Our Events

PPCHEM AG organizes international conferences and seminars all over the world as a platform for sharing experience and discoveries. In addition, PPCHEM also offers seminars and technical sessions for operators.

Over the years, different formats of events have been developed to fit the different needs and interests within the power plant chemistry community.

The Power Cycle Instrumentation Seminar (PCIS)

The Power Cycle Instrumentation Seminar (PCIS) focuses on the analytical methods, the sampling points, and the critical issues for each parameter. The emphasis lies on imparting knowledge about cycle chemistry and an understanding of analytical instruments. Each PCIS consists of a well-proven mixture of theoretical background information on cycle chemistry, sampling, and monitoring as well as analytical methods and instruments, with a practical hands-on session with instruments.

The PowerPlant Chemistry Forum (PPCF)

The PowerPlant Chemistry Forum (PPCF) covers a wide variety of power plant chemistry topics and allows more time for the participants to discuss and share knowledge and experiences in the form of plenary discussions. The PPCF series aims to provide insights into the latest developments in cycle chemistry by sharing operational experience from fossil, combined cycle, biomass, nuclear, and other plants from around the world. The agenda consists of both invited and contributed technical papers and is put together by a steering committee.

PPCHEM Seminars

The PPCHEM Seminars offer easy-to-understand insights into the aims and tasks of power plant chemistry, as well as into the necessary basics, such as water chemistry and corrosion science. While the PCIS and PPCF include a variety of speakers and presenters, the PPCHEM Seminars are led exclusively by PPCHEM's Chief Key Expert Michael Rziha, who is joined by a team of additional invited experts.
