Process water analytics for power plants

In today's energy market green and renewable power is on the rise such like solar power and wind energy. Nevertheless, thermal power plants are still the backbone for the production of electricity and process steam in many countries and industries.

Steam, cooling and condensate - water for every process step

The fuel for these power plants can be coal, oil, gas, nuclear energy or green energy such like biomass and geothermal heat. Thermal power plants operate a thermodynamic cycle where pure boiler feedwater is transformed into steam and driving turbines to produce electricity. The steam can also directly be used to heat buildings or industrial processes. Used steam will be cooled down to form liquid condensate. Condensate is sent back to the boiler to restart the thermodynamic cycle.

Besides the boiler feedwater circuit as the core process, a thermal power plant also needs feedwater makeup systems (reverse osmosis, ion exchangers), a cooling water system, a fluegas scrubbing system and of cause a waste water monitoring system.
