DRYING SOFTWARE – SIMPROSYS: MOTIVATION, DEVELOPMENT, APPLICATIONS AND POTENTIAL ROLE IN PRACTICE

Drying related process simulation requires intensive calculations of not only the states of moist gas for convective dryers, which constitute over 90 percent of all industrial dryers, but also special state variables such as wet-bulb temperature as well as absolute and relative humidity. Due to the nonlinearity and complexity of these calculations, humidity charts were developed a century ago and have been widely used. However, using the century old humidity charts for drying related calculations is obviously inadequate in this electronic age. Given the high price of oil during the past few years and the likelihood that this will not change soon energy conservation technology will once again become a focal point for both industry and academia. Simprosys, probably the first software of its kind, has been developed by Simprotek Coporation (www.simprotek.com) specifically for drying and evaporation based process modeling and simulation.
