Distillation Distillation and Absorption are often the key operation to achieve a required separation. ABN has years of experience with processes including: Batch Distillation Continuous Distillation Azeotropic Distillation Steam Stripping Using computer simulations (ChemCAD) and where necessary pilot plant testing, ABN is capable of finding the most economic solution. The whole range of products available today are evaluated when a distillation system is built. ABN uses proprietary column internals (Sulzer, Montz, a.o.) of high performance.
