Abstract

The most important and well known examples of reactive separations are reactive distillation (RD) and reactive absorption (RA). This chapter introduces the basics of RA and then presents a case study that is relevant to biofuel production. The novel heat-integrated reactive absorption process described here eliminates all the conventional catalyst-related operations, efficiently uses the raw materials and equipment and considerably reduces the energy requirements for biodiesel production-over 85% lower as compared to the RA and RD base cases. Rigorous simulations based on experimental results were carried out using Aspen Plus and Aspen Dynamics. Despite the high degree of integration, the process is easily controllable using an efficient control structure proposed in this work. The main results are provided for a plant producing 10 KTPY fatty acid methyl esters (FAME) from methanol and waste vegetable oil with high free fatty acid content, using sulfated zirconia as solid acid catalyst.
