Thermal Separation Process Technology for the Chemical and Oleochemical Industry

The past two decades are affected by a rapid increase of primary energy cost and changing energy and climate policies. This is commonly encountered by our customers.

The high availability of low pressure steam -also due to coupled processes- as well as the rigid and easy design of thermal separation processes hampered the spread of mechanical vapour recompression systems.

Differently in the food industry: only those utilizing this technology are successful in these markets.

Traditional processes for the concentration of aqueous solutions and solvents are on trial. One is bound to re-evaluate the good old steam heated multi-effect plant compared to new concepts.

Despite higher capex costs plants with mechanical vapour recompression are coming to the fore. Often those concepts are realized as pre-concentrators with MVR and high-concentrators heated by steam or abundant heat.

The results of the evaluation speak for themselves: In most cases a ROI below 2-3 years can be achieved due to lower operational costs. The usage of steam and cooling water is only a fraction of the formerly utilized processes. This is contributing to the climate protection of our planet!

M&L plants excel by optimized energy utilization. The falling film evaporator with its benefits -small pressure losses, low retention time, low capex and maintenance cost- is the most used evaporator execution. The evaporation temperatures are always optimized to the product needs. This allows a gentle product processing and reduces fouling and finally also the cleaning effort.

Beside evaporation as the simplest form of distillation also other thermal separation processes like rectification, adsorption, desorption and deodoration are part of our competence profile. We are offering You complete turnkey solutions as well as only a single apparatus or engineering – up to Your need!

Often thermal separation processes can be coupled. For example the bioethanol production from fermentations by usage of distillation rectification and the concentration and drying process of the distillation slopes for animal feed production can be named. As well the vapours of the drum dryer as well as the head product of the rectification column can be used for driving the evaporation process.

Our experienced process engineers will develop with You the ecological and economical most sensible concept.
