Study on Improvement of Progress of Manufacturing Methods of Acrylic Acid with Quench Absorption Column
摘要:
The concentration of acrylic acid is so high at the top of quench absorption column,resulting in both product and energy loss.The new technology of changing quench column into quench absorption column explored by foreign componies is a effective to reduce overhead acrylic acid concentration and energy cost at the same time.In this paper,NIQUAC-HOC-HENRY mixed model was employed to simulate the existing process and the simulation results were in an agreement with the measured ones.Then this model was used to simulate the new technology and the optimum operation conditions and column parameters were obtained after a comparison of different case-studies.
