Getting Chemistry Right: Forbes Marshall at the PPCHEM AG Seminar 2025
In power generation, the smallest deviation in water-steam chemistry can lead to the biggest consequences. Recognising this critical link between chemistry and plant reliability, Forbes Marshall participated in the PPCHEM AG Seminar 2025, held from 12 – 13 November at the JW Marriott Hotel, Jakarta, Indonesia.
The two-day technical seminar brought together power plant chemists, O&M engineers, instrumentation specialists, boiler manufacturers, and consultants from across Indonesia. With over 58 professionals in attendance, the event created a focused space for in-depth discussions on chemistry control, Steam and Water Analysis Systems (SWAS), and best practices for modern power plants. A strong emphasis was placed on predictive diagnostics, ASME-compliant system design, and the real-world consequences of poor chemistry control.
Sessions opened with compelling global case studies presented by PPCHEM AG, illustrating damage caused by chemistry deviations – reinforcing why adherence to best practices is non-negotiable in today’s cycling and high-pressure plants.
Participants benefited from a series of technically rich presentations covering the full spectrum of SWAS design and application. Topics included:
- Sampling system design and VGB S-006 best practices, highlighting the importance of correct sample conditioning
- Design and selection of pressure parts in sampling systems for reliable long-term operation
- Degassed conductivity (CACE) and dissolved hydrogen monitoring, especially relevant for cycling plants
- SWAS challenges in geothermal applications, including TOC measurement
Technology that enables early detection
Alongside knowledge sharing, the seminar highlighted advanced SWAN analysers for parameters such as pH, conductivity, dissolved oxygen, sodium, TOC, hydrogen, and turbidity, as well as ASME PTC 19.11-compliant sampling probes and conditioning systems. These solutions demonstrated how early detection of chemistry deviations can prevent corrosion, scaling, and costly equipment failures.
Audience engagement was strong, with questions centred around early corrosion indicators, the impact of poor sampling on data accuracy, and selecting the right SWAS configuration for supercritical and cycling units. Swan’s approach to degassed conductivity measurement drew particular interest, while PPCHEM’s damage case studies validated the urgent need for improved specification compliance.
Building stronger foundations for power plant chemistry
The PPCHEM AG Seminar 2025 reinforced a clear message: reliable power generation begins with reliable chemistry. By combining global expertise, proven standards, and advanced analytical solutions, Forbes Marshall continues to support power producers in building safer, more efficient, and more resilient water-steam cycles.
