Water Solubility and Low-Temperature Heat-Transfer-Fluid Performance
Paratherm Corporation to present new research at Chem Show Educational Conference in New York City November 2, 2005.
(PRWEB) October 4, 2005 -- Sean Stoner, Research and Product Development Manager at Paratherm Corporation, recently undertook to explore how the difference in water solubility of two chemically similar heat transfer fluids directly affects coil freeze-ups at fluid temperatures down to -90°C.
Low-temperature heat transfer fluids are used in the chemical processing industries, typically at temperatures down to -50°C, for reactor temperature-control loops, condenser cooling, and freeze drying.
Further lowering that temperature capability, to -70°, -80°, or even -90°C, can theoretically provide fine- and specialty-chemical producers with more options to increase yields, reduce cycle times and/or increase throughput.
But a number of factors come into play at these low temperatures, factors that can sometimes prevent the application of these theoretical advantages. It can be difficult to completely eliminate and prevent water ingress in these closed-loop cooling circuits. While very small amounts typically pose no problem, above certain threshold quantities dissolved water freezes onto the coil surface forming an ice layer that can significantly reduce cooling efficiency and capacity.
Mr. Stoner will present this work at the Chem Show Educational Conference at the Jacob Javits center in New York City, New York on Wednesday, November 2 at 10:30 a.m., as part of the Keep Your Plant Safe, Compliant and Efficient conference track.
Paratherm Corporation's product line has grown to seven heat transfer fluids and two high-performance system-cleaner liquids, but the service mission of Paratherm Engineers and Staff has remained the same; to use their thorough knowledge and experience with thermal systems and heat transfer fluids, their relationships with heater and equipment manufacturers, and their focused attention on the needs of customers, to deliver smoothly operating systems and applications, and maximum production, to processors that choose Paratherm. Paratherm will exhibit at the Chem Show at Javits Center in New York City November 1-3, 2005, in booth 934.
