"Demineralization and Degasification of Boiler Feedwater in Gas Turbine Combined Cycle Plants" - Hot Topic Hour - August 28 at 10:00 a.m. Central Time
The webinar on August 28 will focus on demineralization and degasification in combined cycle gas turbine plants. Participants can review lots of information ahead of time posted to
Degasification and Demineralization. This website covers semiconductor, pharmaceutical, nuclear and coal applications. However, this webinar will be focused on the unique needs of combined cycle power plants. This includes the need for rapid cycling due to the role of the GTCC in supplementing wind and solar. Many new gas turbine plants are using treated municipal wastewater which presents its own set of problems.Tom Tschanz of the McIlvaine Company will provide the initial overview.
Deaeraton with forced and induced draft designs, degasification with vacuum degasifiers and membranes will be analyzed. Locations including pre treatment, post treatment and condensate return will be reviewed. The advantages of the Membrana membrane approach will be compared to alternative mechanical approaches and to the chemical approach which entails continuing chemical cost plus energy consumption and water cost with excess blowdown.
Ion exchange will be compared to electrodeionizaton. Michael Snow president of Snowpure will present the case for electrodeionization. He will address concerns relative to the capability to handle the flow from a large GTCC with the
higher-capacity EXL™ product.Ken Kuruc of Hach will be relating the desired measurements to the reasons why they are important. For example, cationic conductivity is a conductivity measurement after cation exchange: Allcations, and, therefore, ammonium ions (NH4+), are removed and converted into Hydrogen ions (H+). Inorganics (chloride, sulfates) and organics (acetate, formate)anions present (counter ion of cations, Cl-, SO42-) can be easily determined because they are in their highly conductive acidic form (H+, Cl- ; 2H+, SO42-). Any increase in cationic conductivity highlights anionic contamination. A detailed analysis of the instruments, processes and measurement locations by Hach is posted on the site.
Brad Bueker of Kiewit will summarize from direct experience and also the extensive work of personnel at organizations such as the Electric Power Research Institute (EPRI) to show that 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 attacks have caused numerous failures, some with fatalities, at a number of power plants in the U.S. Yet, specifications for new power plants, most of which are now combined cycle units, often continue to call for oxygen scavenger feed to the condensate, even though the feedwater system typically contains no copper alloys. He presented a paper on this subject at IWC. We will seek permission to reproduce it for the site.

Reverse Osmosis Equipment and Membranes Will Account For 50 Percent of the Cross-Flow Market Next Year
Sales of cross-flow membranes and equipment will exceed $10.8 billion in 2015. Fifty percent of this total will be spent for the more efficient reverse osmosis technologies. The remainder will be split between ultra filtration and microfiltration. This is the latest forecast in

Desalination applications will account for much of the market. Reverse osmosis provides the desalting. The other membrane technologies are often used for pre-filtration. The Middle East remains a major purchaser of desalination systems. The recent decision by Dow to locate a reverse osmosis module manufacturing plant in the region is indicative of the importance of the region.
Membrane technology growth in Asia is in part due to the need to upgrade the quality of drinking water. The size range of reverse osmosis membrane modules has been expanding. A 500 gallon per day module is now available. A tankless design is now possible with this large size module.
Water reuse at power plants is also driving the expansion of the cross-flow membrane market. Many combined cycle gas turbine plants under construction and planning in the U.S. are relying on treated municipal wastewater as the water source.
Ultrafiltration and microfiltration continue to be popular in the pharmaceutical and chemical industry as a way to separate products.
