Avoid These 10 Mistakes When Selecting Your New Water Treatment System
There are a number of reasons why your plant might be looking at new water pretreatment equipment in the near future. One common reason is the addition of new generating capacity. Regardless of the type of new generation, you can be sure that it will require additional high-purity water for processes ranging from direct steam generation to power augmentation, NOx control, and washing the blades of the combustion turbines.

Top Plants: Edward W. Clark Generating Station, Clark County, Nevada
The Edward W. Clark Generating Station, which has supplied electricity to the Las Vegas Strip for more than half a century, has learned the secret of life in the desert: adaptability. The plant’s early years featured conventional steam plants operated around the clock. By mid-life, Clark had been upgraded with two combustion turbine combined-cycle power blocks operated as intermediate-load resource. Today, the old steam plants have been replaced with fast-start peaking gas turbines.

Top Plants: Goodman Energy Center, Hays, Kansas
Midwest Energy has a history of thinking and acting independently, especially since breaking away from the Rural Utilities Service almost 15 years ago. Two years ago, when its board of directors grappled with finding a balance between purchasing and generating electricity, it decided to construct its first power plant in 37 years. A matched set of nine 8.4-MW gas engines at Goodman Energy Center now provides efficient peaking electricity, improved overall system reliability, and backstop capacity for a 325-MW electrical system that features 16% wind power generation.

Copenhagen’s Neverland
The world’s war on carbon emissions isn’t going well. In just six months, the UN sponsored Copenhagen Conference on Climate Change will seek to launch a worldwide anti-carbon strategy with teeth. Billed by alarmists as “the last chance to save our planet,” all the signs are that Michael Jackson has a better chance of recording new material than Copenhagen has of delivering a meaningful international accord.

Combined-Cycle Carbon Capture: Options and Costs, Part I
Uncertainty about CO2 emissions legislation is prompting power plant owners to consider the possibility of accommodating "add-on" CO2 capture and sequestration solutions for coal-fired plants in the future. Those same plant owners may be overlooking the possibility that future natural gas – fired combined cycles will also be subject to CO2 capture requirements. This month we examine the capture options. In a future issue, Part II will present the installation and operating costs of different carbon capture technologies.
