Base Water-Quality Specs on Reality, Not the GT OEM
Even if you don’t have a steam cycle, chances are your gas-turbine plant uses plenty of treated water—for evaporative cooling or inlet fogging, water/steam injection for NOx control and/or power augmentation. The quality of this water is critical to minimize deposition and corrosion problems.

Power Plant Chemicals Webinar - Hot Topic Hour September 25, 2014
The level of knowledge demonstrated by the speakers relative to the challenges of preventing corrosion and malfunction of gas turbine combined cycle plants which are cycling hundreds of times per year and may be using poor quality source water makes a persuasive case for continuing expert advice.

Ion Exchange and Reverse Osmosis
The water treatment plant at a coal and biomass-fired power plant in the Netherlands was 35 years old and needed to be replaced. Ovivo provided an ion exchange and reverse osmosis system which upgraded the boiler feedwater quality to the new standards without replacing the condensate polishing plant.

The reducing environment produced by oxygen scavengers initiates and propagates flow-accelerated corrosion (FAC) in the feedwater system and other components of high-pressure steam generators, including heat recovery steam generators (HRSGs). Since 1986, FAC-induced attack has caused numerous failures, some with fatalities, at a number of power plants in the U.S. Yet, specifications for many new power plants both domestically and globally, and in which the condensate/feedwater system contains no copper alloys, continue to call for oxygen scavenger feed to the condensate. This document is a response to this misguided trend.

Providing Israeli Utility With Demineralized Water
The Israel Electric Company, which chose to convert some of its inland power generation stations to use natural gas, needed a high-quality source of demineralized water to generate steam for the high-pressure boilers and inject UPW in their gas turbines for NOx reduction in its combined-cycle power stations.
