Oil in Power Plant Wastewater
The water is from the operations of a steam power plant located in the Bahamas. The water samples were taken from the Unit 31 (lower oil content) and Tank #3 (a higher oil content). The samples were tested and it was found through the jartesting procedures that the Floccin K was the best choice for floc size and water clarity. The Unit 31 was dosed at 0.5 gram in 1,000 ml and the Tank # 3 water ...

Project - Malaysia Power Plant - regeneration
Capacity: 500MW A major power generator in Malaysia owns and operates two turbines operating in Malaysia. The turbines, GT1A and GT2A, are gas fired and both have an operating capacity of 250MW. Two SmartCEM 60 Analyzers were installed to determine the effectiveness of PEMS as an alternative to CEMS for gas turbines. A study was conducted to determine which parameters would be suitable for ...

EDI for Power Plants -- Importance of silica
Power plants use high purity water to drive steam turbines. Cogeneration plants are highly efficient, using both exhaust turbines and high pressure steam turbines. In the 1960's, boilers operated at 450C (840F) and 4MPa (40 atmospheres). Today's leading edge boilers operate at 620C (1150F) and 30MPa (300 atmospheres). To keep power efficiency high, maximize uptime, and minimize turbine ...

Electrodeionization for Power Plants — Importance of Silica
Power plants use high purity water to drive steam turbines. Cogeneration and combined-cycle power plants are highly-efficient, using both exhaust turbines and high-pressure steam turbines. The steam must be of the highest purity. In the 1960’s, boilers operated at 450°C (840°F) and 4MPa (40 atmospheres). Today’s leading edge combined cycle systems operate at 620°C ...

Power Plant Turns Waste into Treasure
Chen is a veteran driver of a sewage treatment plant. At 9 o'clock every morning, he drove a closed transport truck to start his day's work. The sewage treatment plant is the largest sewage "reservation station" in Cangshan District, Fuzhou City, Fujian Province, and 200,000 tons of sewage have to be "reported" here every day. The sludge formed after sewage treatment will be compressed into a ...

Monitoring Oil in Cooling Water - Case Study
The Situation A municipal power plant in the southern United States operates more than 10 stationary power plant engines capable of producing 52 megawatts of electric power. The plant is part of a larger statewide power grid system. Within the grid, the municipality brokers the purchase or sale of power hourly, based on the needs of municipality and the market rate for power on the grid system. ...

An application of a puff dispersion model on power plant emissions in Yatagan region, Turkey
The present paper describes the application of the CALMET meteorological model and CALPUFF plume dispersion model to the Yatagan district to study the impact of Yatagan Power Plant emissions on the SO2 levels on December 2000 in the region. Results indicate that SO2 concentrations over the city depend strongly on advected emissions from the power plant and on the local variation of the wind field ...

Drought risk modelling for thermoelectric power plants siting using an excess over threshold approach
Water availability is among the most important elements of thermoelectric power plant site selection and evaluation criteria. With increased variability and changes in hydrologic statistical stationarity, one concern is the increased occurrence of extreme drought events that may be attributable to climatic changes. As hydrological systems are altered, operators of thermoelectric power plants need ...

ADMS 5 Complex Terrain Validation Tracy Power Plant
1 Introduction The Tracy Power Plant is situated 27 km east of Reno. Nevada, in a region of complex terrain. The power plant is in a valley surrounded by peaks rising to around 950 m above the power plant elevation. During 1984. the United States Environmental Protection Agency carried out a series of 14 experiments between August 6th and 27th. for a total of 128 hours of data collection, mainly ...

A mixed-integer non-linear programming model for CO2 emission reduction in the power generation sector
Electricity generation is considered to be one of the main contributing sources to the air pollution problem. It is, therefore, important to develop and implement effective control strategies to prevent the expected abrupt increase in emissions from this sector. Any control strategy must be suitable for local implementation and must also be economically viable. The main objective of this paper is ...

The Flakt-Hydro process: flue gas desulfurisation by use of seawater
ABB's seawater scrubbing process (the Flakt-Hydro process) for flue gas desulfurisation has recently triggered much interest among power producers because of its simple operating principle and high reliability. The process uses seawater to absorb and neutralise sulfur dioxide in flue gases. The absorbed gas is oxidised and returned to the ocean in the form it originated in the first place, namely ...

ACTIFLO® Clarifiers are Heart of Antioch, CA Recycled Water Facility
Due to a number of economic and ecological factors, the California State Water Resources Control Board requires power plant developers to evaluate the use of recycle water for cooling tower needs. For this reason, Calpine (a power plant developer) formed a public-private partnership between itself, Bechtel Enterprises and the Delta Diablo Sanitation District (DDSD) to build a new recycled water ...

Beta Switches Provide Solutions
Power plants inherently have high pressure process applications that require safety shutdown should pressures exceed requirements. BETA's W and C series pressure switches provide the high level of accuracy, repeatability and dependability needed for these potentially dangerous applications. High pressure steam and pressurized natural gas feeder lines are two of the most common high pressure ...

Energy and exergy analyses of a supercritical power plant
Energy and exergy efficiencies of a supercritical power plant have been studied in this paper. The effect of ambient weather condition was considered on the condenser pressure. It was shown that high ambient temperature has more adverse effect on the exergy efficiency than the energy efficiency. As ambient temperature increases, the exergy efficiency of the boiler, condenser, heaters and feed ...
