Cogeneration projects

CAMET control catalyst was shown to obtain 80% NO reduction and 95% carbon monoxide reduction in this appHcation in the Santa Maria, California cogeneration project. The catalyst consists of a cormgated metal substrate onto which the active noble metal is evenly deposited with a washcoat. Unlike the typical 20 on titania turbine exhaust catalysts used eadier in these appHcations, the CAMET catalyst is recyclable (52).

Most of the turbines you will encounter in your work are called topping, or extraction, turbines. The idea of such a turbine is to extract much of the potential work from the motive steam, and then use the exhaust steam to reboil towers. Typically, the energy content of the exhaust steam is only 10 to 20 percent less than that of the motive steam. That is the calculation we just did with the Mollier diagram. The rest of the energy of the steam may then be used as the steam condensers, to reboil towers. This sounds pretty efficient. It is the basis for the new cogeneration projects you may have heard about. Of course, this system was used by the British Navy in the nineteenth century. 

Also, cogeneration project developers are seriously considering petroleum coke as a viable fuel source. The Delmarva Power plant in Delaware City, Delaware has been producing electricity and steam for Getty Oil s nearby refinery for several years. Atlantic Richfield is currently constructing a cogenerator at its Houston, Texas refinery with start up expected in 1986. The ARCO project will generate 135 MW and consume 500,000 tons of petroleum coke each year.

A major coal-fired cogeneration project (conservation) will cost several billion dollars (Kenney). 

In 2003 the Department of Energy announced FutureGen, also known as the Integrated Sequestration and Hydrogen Research Initiative. This is a 10-year, billion dollar project to produce a 275-MW prototype plant that will cogenerate electricity and hydrogen and sequester 90% of the C02. 

The U.S. Department of Energy (DOE) has started the billion- dollar, FutureGen project to demonstrate a 275-megawatt prototype plant that cogenerates electric power and hydrogen and sequesters 90% of the C02.

Therefore, it is anticipated that this initial project will lead to broader social and environmental advances and act as a model for further cogeneration plants. Conversion of hydro, wind and, solar energy to electricity and to hydrogen will open a new venue for the efficient utilization of renewable energy resources in Azerbaijan. 

What, then, does the future hold This author believes that the catalytic hydrocarbonization/gasification concept will ultimately achieve commercial success for the production of liquid and gaseous fuels from coal. In selected applications, the mild hydrocarbonization of western coal to produce liquid and gaseous fuels with power generation from the low-sulfur char may also be commercially attractive. Finally, further development of the flash hydropyrolysis technology, as exemplified by the Rocketdyne project, may eventually lead to a technically and economically attractive liquefaction process. But the most important questions still remain unanswered. Does private industry have sufficient interest to pursue the possibilities Where is the interest focused Will a private consortium build a hydrocarbonization/ cogeneration complex using western coal Will the phoenix arise from the ashes ...
