K. Nagamalleswara Rao, M. Venkata Ratnam, P. Rajendra Prasad, V. Sujatha


This paper presents the design and control of acrylic acid production process using Aspen Plus and Aspen Dynamics. Propylene reacts with oxygen and produces acrylic acid and water. Plant-wide operability and control of the entire acrylic acid production plant with controllers is explained. The results indicate that the proposed process gives good dynamic performance (a settling time of less than 3 h).
