Milestones in Separation Technology GEA Leaves Nothing to Chance when it Comes to the Fundamental Step of Separation

Editor: M.A. Manja Wühr

Regardless of whether for distillation, filtration, drying or clarification — without separation technology, nothing goes. After all, most raw ingredients and products of chemical reactions are mixtures of substances that need to be separated for further processing. So it is good to have a partner who is a single provider capable of supplying everything from mechanical separation systems to exhaust air purification.

For example, the company supplies systems for thermal separation of multicomponent mixtures through distillation/rectification, evaporation and crystallization. With the aid of these methods it is possible to produce the ultra-pure substances that are required for further processing into high-quality products.

For the separation of solids from liquids, GEA offers a large number of drying techniques such as spray drying, fluidized bed drying and freeze drying, which are used in the production of all types of powder, whether organic or inorganic.

Since thermal processing is very energy intensive, the main focus of GEA is on saving energy. Thanks to specially developed technologies and clever interconnection of the thermal transfer components, the energy that is fed into a system is used multiple times. A substantial plus in terms of energy consumption!

The perfect mechanical solution: Cross-flow membrane filtration is the technology of choice for many industrial processes in which products need to be separated or concentrated without application of heat. There are applications for this solution in the fields of biotechnology, the chemical/pharmaceutical industry, the food industry and the dairy industry. Cross-flow membrane filtration protects products that are sensitive to heat, and at the same time it offers precise separation through the use of specially selected membranes and plant configurations.

If the product in question has a high solids content, this is where decanters come into play. They deliver high clarification performance and ensure the maximum possible dewatering, or offer the separation of liquids with the simultaneous removal of solids. Using centrifugal force, they are used for separating suspensions consisting of two or more phases of different densities.

The requirements for separation technology processes in exhaust air purification are completely different — solids such as dust particles are separated from gaseous media with the aid of fabric filters or electrostatic precipitators, or different gases are separated by washing out, absorption or chemical reaction.

Based on the vast number of in-house test reports and the availability of test and pilot plants, GEA is able to offer its customers tailor-made solutions to provide them with the best available separation systems.
