Wet-Dry Technology to Abate the Visible Plume from an Existing Cooling Tower Mark Scholl, Alliant Energy and Jean-Pierre Libert, Evapco Inc. 2017
Abstract: Alliant Energy’s Riverside Power Plant in Beloit, WI undertook a cooling tower upgrade project in 2015 to reduce the visible plume from the existing wet cooling tower at a combined cycle power plant. The plume was impacting yard operations at an adjacent Operations Center, several residences, and a high travel county highway. Several different options were investigated and EvapTech’s EVAPDRI wet-dry technology was ultimately selected for this demonstration test. This paper will discuss the challenges of the project and how they were resolved: operational results of the wet cooling tower in winter with significant plume impact, permit limitations, retrofit and installation of metallic heat exchanger coils in the existing FRP Cooling tower structure while in operation, water management issues while utilizing existing plant piping, startup and measurement of the effluent air and plume characteristics of the modified cell, permitting and planning of future activities to retrofit the entire cooling tower.
Cooling Tower Plume Jan Cizek, Czech Technical University in Prague 2017
Abstract: The paper describes the behavior of supersaturated moist air in the space above the cooling tower where the formation of the, so-called, visible steam plume occurs. In order to correctly determine the possibility of eliminating plume, it is necessary to understand the basic principles for formation of the plume, and the main factors impacting such formation. For this purpose, a simple mathematical model of the problem was prepared based on the use of analytical and empirical relationships that form the basis for derivation of the basic dependence of the plume diameter on the crucial physical parameters.
Cooling Tower Plume Jean-Pierre Libert, Evaptech, Inc. 2011
Abstract: Evaporative cooling systems emit a visible plume a significant portion of the time. Even though a cooling tower plume contains mostly pure water and hardly any pollutants, it is often seen as a nuisance. This paper describes the psychrometry of the plume under typical operating conditions and reviews how to specify no visible plume. Several technologies exist to reduce or abate the visible plume and these techniques will be shown. A new technology will be introduced which has the capability of saving water while inherently reducing the plume. Based on this new technology, an additional technology is proposed to abate the plume under more severe operating conditions.
