Abstract
Water treatment compositions useful to decrease surface tension of cooling tower waters are provided as are treated cooling tower waters. The compositions increase the transfer of heat from metal surfaces in contact with the treated cooling water. The increased heat transfer can decrease energy use, for example, in water-cooled HVAC and refrigeration compressors, and can enable increased production rates in many industrial processes, including, for example, plastics molding, metal billet production, petroleum refining, power plants, and condensers for steam turbines. Also provided are cooling tower water compositions formulated to control corrosion, scale, and deposition in a cooling tower and in treated cooling tower water.
Claims20
A water treatment composition comprising an aqueous solution of a coupling agent and an alkoxylated nonoxynol, the coupling agent comprising one or more coupling agents selected from sodium xylene sulfonate, potassium xylene sulfonate, ammonium xylene sulfonate, sodium toluene sulfonate, potassium toluene sulfonate, and ammonium toluene sulfonate
A cooling tower water treatment composition comprising an aqueous solution of an ethoxylated nonoxynol (6-14) surfactant exhibiting a hydrophobic/lipophilic balance (HLB) of from 10 to 14, and a coupling agent, the coupling agent comprising a xylene sulfonate or a toluene sulfonate, wherein the ratio of the ethoxylated nonoxynol (6-14) surfactant to the coupling agent is from 0.5:1 to 3.5:1 based on weight.
