Welcome to Fluitec

Successful optimisation of a hydrogenation reactor and significant catalyst savings with the new Contiplant reactor from Fluitec.

It is well known that almost all hydrogenation reactions take place under mass transfer limited conditions. In addition, there is an increasing demand for the use of catalyst powder in small quantities.

Due to a novel gassing concept and an efficient cooling system, higher mass transfer rates and thus higher space-time yields can be achieved in the Fluitec reactor at pressures of up to 100 bar and temperatures of up to 250°C as standard, with generally improved product quality. The payback time for converting a trickle bed reactor to a Fluitec hydrogenation reactor is only 1-3 catalyst changes. Furthermore, there is the possibility of measurement of the temperature profile in the reactor. This allows not only process optimisation but also safe and reliable reaction monitoring.

Fluitec offers complete assemblies for precise temperature control of food products. Viscous and temperature sensitive products can be gently heated up or cooled down without causing any damage to the product such as discolouration and encrustation due to local temperature peaks.

The Fluitec CSE-XR and CSE-W heat exchangers have proven themselves in the food sector as the core components. The systems can be equipped with pumps, instrumentation and controls and installed on a rack.

A good surface finish of the components with low surface roughness and good cleanability of the equipment is very important to Fluitec. The picture shows a Fluitec system for tempering chocolate for a throughput of 450 kg/h.

Possible applications:

• Chocolate and filling masses
• Animal and vegetable fats such as margarine
• Vegetable oils
• Dairy products such as in the pre-cooling of milk
• Peanut butter
• Processed cheese
• Sugar masses
• Sauces and ketchup

Scale-up of mass transfer limited processes (gas-liquid or liquid-liquid) is challenging, as the mass transfer rate should be kept constant during scale-up. This requires well-characterized flow reactors in terms of pressure drop and kLa correlations even at lab scale. Fluitec offers static mixer test reactors with a clearly defined mixing performance that allow direct scale-up to laminar/turbulent static mixers as well as mixer heat exchangers.
