Abstract

The potential benefits of implementing several different thermal management approaches to a reactive distillation (RD) system were studied. This was demonstrated using the production of diacetone alcohol (DAA) and mesityl oxide (MO) from acetone dimerization and subsequent dehydration. The selectivity for DAA was quite sensitive to the reboiler heat duty, indicating that the thermal management in this RD process can play key role in optimizing the product selectivity, conversion rate, and energy efficiency. An Aspen+ model for a heat integrated reactive distillation (HIRD) was developed. In one configuration, the latent heat from the overhead condenser was recovered and introduced at selected stages to determine the optimum heat integration. Other configurations evaluated involved both the addition and removal of heat at different stages. The configurations with the greatest energy savings at constant throughput and purity were presented and the effect of HIRD on production rate at a constant energy requirement was discussed. This is an abstract of a paper presented at the 2012 AIChE Spring Meeting and 8th Global Congress on Process Safety (Houston, TX 4/1-5/2012).
