Varied in line with each application, our design concepts take into account the product characteristics, cleaning concepts, the required capacity, availability and pressure of steam and cooling water as well as local energy costs.
Since concentration and hence the properties of the evaporated solution change considerably during the process, a well-chosen combination of different evaporation modes in one unit ensures high efficiency.
for stillage from alcohol production comprising both forced circulation and falling film evaporators.
This system is suitable for low and medium solids content and viscosity. It can handle small differences of temperature well which makes it suitable for temperature sensitive products. Ample recirculation rates ensure high turbulence in the falling film resulting in a reduced tendency to fouling.
Besides a low consumption of electrical energy, a small footprint and less steel structure, its characteristic is a small hold-up inside the evaporator with the result of a low demand of cleaning liquids / agents and reduced thermal exposure of the concentrated product.
Rising film evaporation in plate type evaporators is a feasible option for media having low tendency to fouling. Due to the minimized hold-up in this type of evaporator it is widely used for concentration of temperature-sensitive products and offers further advantages due to its compact design and low investment costs.
Typically used for feeds with medium to high solids content and viscosity. Its multipass design for high velocity in the pipes leads to high turbulences inside the tubes which minimizes fouling tendencies. Consequently it has the longest operation periods between cleaning cycles.
As an engineering company without inhouse fabrication we can independently select the best type of evaporator procured within our global supplier network.
Our services for evaporation plants include the process design, detail engineering or review of client’s detail engineering, the supply of equipment or procurement assistance, automation including field instruments and hard- and software of DCS as well as on-site supervision. Alternatively the complete unit can be provided within an EPC solution.
As far as practicable, systems can be prefabricated in easy-to-install skid-mounted modules.
Our advanced thermal integration techniques save energy by improved heat recovery and re-use of secondary energy in evaporation plants.
