Sulzer Process Technology is a leading expert and solutions provider for a range of distillation technologies such as Continuous and batch distillation, Single- and multi-stage distillation, Extractive distillation, Azeotropic distillation, Pressure swing distillation, Reactive distillation and divided wall columns.

Reactive distillation is a state-of-the-art development combining distillation and chemical reaction in one single operating unit. This technology is highly valuable for equilibrium-limited reactions, such as esterification. The level of conversion is increased by continuously removing the reaction products from the reaction zone via distillation. In general, reactive distillation units feature fewer distillation columns, no (or smaller) recycle streams, utilization of heat of reaction for mass transfer, higher product yields, lower capital investment and lower energy costs.
