Abstract
This paper takes the conversion system of sulphuric acid plant made with the sulphur as research object, utilizes Aspen Plus process simulation software to carry out steady state process simulate for the conversion process, and obtains physical property data of all the process streams; utilizing Aspen Energy Analyzer software, that the minimum heat transfer temperature difference (ΔTmin) determined is 10 °C, the temperature-enthalpy composite curve and the pinch temperatures of hot and cold streams are got under the ΔTmin, the energy consumption of heating utilities reaches zero, and cooling utilities use 45 °C of desalted water. Simulating for heat exchange network with pinch technology and Simulating the matching design of heat exchange network with Aspen Energy Analyzer software, the heat exchange effect is basically as same as the heat exchange network in actual production.
