Cooling Tower
Plant equipment that is used to dissipate heat into air rather than into a river. Cooling is induced in two different ways. For binary plants, dry cooling towers use fans to draw air across a heat exchanger and this removes heat from a working fluid causing gas to condense into liquid. In flash steam plants, wet cooling towers condense water vapor via evaporation to provide a continuous supply of cooled water that is run through the outlet of a condensing turbine.

Word of the Week – Well Casing
Well Casing Large diameter pipe that is assembled and inserted into newly drilled intervals of a well. The upper portions of a cased well are commonly cemented in place to provide a smooth internal bore, and prevent the inflow of water and/or collapse of the hole.
Word of the Week – Wellhead
Wellhead Surface equipment at the top of a well (oil, gas, geothermal) that provides a structural and pressure-containing interface for drilling and production equipment. It is used to support and attach the anchor casing via a welded connection. Other flow valves...
Word of the Week – Well Logging
Well Logging Methods used to survey and characterize the physical and geological characteristics along and near the wall of a well, including the temperature, pressure, fracture density, fracture orientation, porosity, rock type, casing integrity, and fluid...
