Flow rate of a phase separation element as a function of process parameters. The flow rate is relative to the average cross-section
or inflow zone of the microfiber bed. The inflow zone of a phase separation element of type FTC IV/1250 is 0,5 m².

Phase separator with collection dome for the
separated (heavy) phase. Viewing ports are

For laboratory and pilot plant scale testing,
we are able to manufacture phase separation
elements of smallest dimensions for subsequent
scale-up (e.g. Ø 50 mm)

FTC Phase Separation Elements

Optimum phase separation is achieved by engineering the relevant fiber bed parameters to the specific separation task at hand. High porosity can be achieved, resulting in low pressure losses and high specific loads, even when viscosity is extremely high.

The pressure loss to be taken into account is typically 0.05 to 0.8 bar.
Complete manufacture on our premises means that delivery lead times for
the optimized phase separation elements you order are cut to a minimum.
For liquid-liquid dispersions containing solids, a pre-filter is appropriate.

Phase separator with fast-change system - fast opening via segment clamping screws and cover swivel device - no need to loosen pipes - individual phase separation elements can be replaced (max. weight: 13 kg) Phase separation stage Even larger assemblies are easy to handle.		Phase Separation Stages Phase separators are assembled using the modular components of our adaptable system: no compromises, easy to remove and modify. Phase separators are built around the phase separation stage, consisting of support plate, phase separation elements and cross support plate. The technical separation of very finely dispersed droplets is achieved through our phase separation elements. The phase separation stage provides easy handling as a functional unit. Future upgrading and adaptation are built into our design approach.


Tiny droplets flow into the microfiber bed. During coalescence large droplets are formed and exit the microfiber bed. Flow rate of a phase separation element as a function of process parameters. The flow rate is relative to the average cross-section or inflow zone of the microfiber bed. The inflow zone of a phase separation element of type FTC IV/1250 is 0,5 m². Stainless steel microfibers, magnification x 250		Technology Phase separation elements function by coalescence in a special microfiber bed. This achieves separation of the dispersed phase up to the limit of solubility, even with droplets as tiny as 0.1µm, and with media of high viscosity. Separation and flow rates are determined by the following parameters: - Fiber bed volume - Fiber diameter - Porosity - Coalescence behavior Our manufacturing technology enables optimization in special applications. The microfibers we use are pure, untreated and of defined coalescence behavior. Special manufacturing techniques ensure that the diameter and length of fibers are uniform. By applying a range of different materials in fiber manufacture, we are able to meet any chemical or thermal requirements. This is why our phase separation elements provide maximum separation and flow-through rates. Theory coupled with know-how is the cornerstone of our engineering approach. Fluid dynamics of the two-phase mixture and droplet coalescence are calculated on the basis of process data. Computer simulation provides us with: - Specification of the microfiber bed - Size and number of phase separation elements - Dimensions of the phase separator - Separation and fluid dynamic - Pressure loss Theoretical performance may be influenced by a number of factors in practical application: - Changes in process conditions, e.g. fluctuations in temperature ..or viscosity - Material specifications for the microfibers if medium is corrosive - Extra capacity to cope with later increases in throughput These boundary conditions are additionally built into our calculations.

PT Phase Separators The dimensions of phase separator vessels are determined by process calculation. Phase separators are calculated as pressure vessels to local (national) specifications. Material for vessels can be freely selected. - Steel - Stainless steel - Plastic - Interiorly coated materials, e.g. rubber-coated or enamelled Existing vessels or separators can often be upgraded using a phase separation stage as a functional unit. *) Flow rate under standard conditions
