Aspen Plus tutorial (2) – physical property analysis
When we design the process of distillation, extraction and reaction, we often need to know the vapor-liquid equilibrium and liquid-liquid equilibrium relationship of each component, as well as the basic properties of the system such as density, viscosity and vapor pressure. These properties can be analyzed by Aspen Plus / tools / analysis tools to analyze the physical properties of pure components, binary components, ternary mixtures or a certain logistics. Example: chloroform / acetone / water system, physical method NRTL. ① The relationship between vapor pressure and temperature of chloroform was analyzed in the range of 20 ~ 100 ℃; ② The vapor-liquid equilibrium of acetone / water system at 1atm was analyzed; ③ The liquid-liquid equilibrium of ternary system was analyzed. Firstly, the components were input and NRTL was selected as the physical property method ① The relationship between vapor pressure and temperature of chloroform was analyzed in the range of 20 ~ 100 ℃ Click pure in home Finally, the running results The specific vapor pressure can be viewed in results ② The…
Aspen Plus tutorial (1) – a practical simulation of a simple flash example
Learn Aspen Plus through an example of flash evaporation. This example introduces a series of operations such as component input, process establishment, physical property selection and actual simulation operation. Flash evaporation is a common and simple unit process in chemical production.
