Unit Operations

The most important unit operation in thermal process engineering is distillation, which has such wide application. A&D AS Solutions Process Industries offers a complete range of services for this operation:

• Rigorous simulation of distillation columns using physically based models
• Dimensioning of the column and selection of appropriate internal equipment
• Design of additional equipment (evaporator, condenser, decanter)
• Design of constructive details
• Optimization of the separation sequence
• Setting up a control concept
• Concepts for separation of azeotropes (decanter, extractive distillation, crystallization etc.)
• Reactive distillation
• Distillation trials for single columns and column sequences
• Safety analysis

Distillation is the most important, but not the only, unit operation for fluid separation: absorption, extraction and crystallization as well as adsorption and membrane separation often prove to be more suitable than distillation and are successfully employed by us.

Our specialists work on the development of these operations both theoretically and experimentally. Our customers benefit from being provided with the best process option.
