The Draft Tube Baffle Crystallizer is an elaborated Mixed Suspension Mixed Product Removal (MSMPR) design, which has proven to be well suited for vacuum cooling and for processes exhibiting a moderate evaporation rate. The concept is such that if no (or little) heat make-up is required, it results in a rather compact arrangement; therefore the initial investment is minimized.

As a rule, these units operate with a rather low supersaturation, which is sometimes a limitation to crystal growth, so that very large crystals can be produced only by providing extensive and costly dissolving of fines.

The Draft Tube Baffle unit (Figure 1) includes a baffled area (settling zone), peripherical to the active volume, from where excess of mother liquor and/or fines are removed for further processing. The necessary agitation of the suspension mixed with the incoming feed solution is provided by a bottom entry agitation at moderate energy consumption.

Draft Tube Baffle crystallizers are often equipped with an elutriation leg below the body to classify the crystals.

When destruction of fines not needed or wanted, baffles are omitted and the internal circulation rate is set to have the minimum nucleating influence on the suspension (Draft Tube design, draft-tube crystallizer).

When large evaporation rates are required, an external heating loop must be provided, making the arrangement less competitive from an initial cost standpoint.

TypeIndustrial

A falling film evaporator is an industrial device to concentrate solutions, especially with heat sensitive components. The evaporator is a special type of heat exchanger.

In general evaporation takes place inside tubes. But there are also applications were the process fluid is located on the outside tube. The process fluid to be evaporated flows as a continuous film downwards controlled by gravity. The fluid will create a film along the inner tube walls, progressing downwards (falling) - hence the name. The Fluid distributor has to be designed carefully in order to maintain an even liquid distribution for all vertical in parallel aligned tubes through which the solution falls.

In the majority of applications the heating medium is placed on the outside of the tubes. High heat transfer coefficients are required in order to achieve equally balance heat transfer resistances. Therefore most commonly condensing steam is used as a heating medium.

Separation between the liquid phase (the solution) and the gaseous phase takes place in the tubes Increasing vapour velocities downwards to the bottom of the exchanger increases the shear force acting on the liquid film and therefore also the velocity of the solution. The result can be a high film velocity and a progressively thinner film resulting in increasing turbulent flow. The combination of these effects allows very high heat transfer coefficients.

Rolled ShapeRectangular Bar

Batch pan evaporators consist of spherical shaped, steam jacketed vessels. The heat transfer per unit volume is small requiring long residence times. The heating is due only to natural convection; therefore, the heat transfer characteristics are poor. Batch plants are of historical significance; modern evaporation plants are far-removed from this basic idea. The vapors are a tremendous source of low-pressure steam and must be reused. Batch pan systems are used in some jam processes. Soluble solids are increased to 65% or above in a jacketed vacuum kettle. Evaporation of liquid in open pan evaporator is achieved by use of internal coils, direct heaters, or by means of jackets. When heat sensitive products are to be processed, the heating vessel is connected to a vacuum system so that boiling of the product occurs at lower temperatures.

Flash Evaporator

A flash evaporator unit for a multistage flash evaporation plant wherein successive evaporation stages are operated at successively decreasing temperatures and pressures to evaporate water from a brine solution, said evaporator unit comprising:an elongated enclosure having opposed end walls; a tube bundle extending between said end walls to provide at least one upper condenser chamber to which vapor is directed from a lower evaporation chamber through which brine flows in the cross-direction; means including a tray for collecting distillate from said tube bundle; duct means extending in the cross-direction through successive evaporator units in said plant and disposed to collect distillate from said tray means; means for holding the tray distillate in a space isolated from said duct means prior to its entry into said duct means; means for detecting the conduction of the duct distillate outflow from said evaporator unit; and means for bypassing distillate from said holding space to an evaporation chamber in the same or a subsequent stage so that contaminated distillate can be withheld from the accumulating distillate flow in said duct means when said detecting means indicates said evaporator unit is producing contaminated distillate.


Oslo Crystallizer


Oslo type crystallizer also called classified-suspension crystallizer is the oldest design developed for the production of large, coarse crystals.


The basic design criteria are twofold:
  • Desupersaturation of the mother liquor by contact with the largest crystals present in the crystallization chamber.
  • keeping most of the crystals in suspension without contact by a stirring device, thus enabling the production of large crystals of narrow size distribution.

The classifying crystallization chamber is the lower part of the unit. The upper part is the liquor-vapor separation area where supersaturation is developed by the removal of the solvent (water for most applications). The slightly supersaturated liquor flows down through a central pipe and the supersaturation is relieved by contact with the fluidized bed of crystals.


Conispherical Magma Crystallizer

Crystals are grown in many shapes, which are dependent upon downstream processing or final product requirements.  Crystal shapes can include cubic, tetragonal, orthorhombic, hexagonal, monoclinic, triclinic, and trigonal.  In order for crystallization to take place a solution must be "supersaturated".   Supersaturation refers to a state in which the liquid (solvent) contains more dissolved solids (solute) than can ordinarily be accomodated at that temperature.

As with any separation method, equilibrium plays an important role.  Below is a general solubility curve for a solid that forms hydrate (a compound that has one or more water molecules attached) as it cools.

On an industrial scale, a large supersaturation driving force is necessary to initiate primary nucleation.  The initiation of primary nucleation via this driving force is not fully understood which makes it difficult to model (experiments are the best guide).  Usually, the instantaneous formation of many nuclei can be observed "crashing out" of the solution.  You can think of the supersaturation driving force as being created by a combination of high solute concentration and rapid cooling.  In the salt example, cooling will be gradual so we need to provide a "seed" for the crystals to grow on.   In continuous crystallization, once primary nucleation has begun, the crystal size distribution begins to take shape.  Think about our salty water, as you look at Figure 2 describing the progression of crystallization.

Rising Film Evaporator

Minimum Order Quantity: 1 Piece

Automatic GradeAutomatic, Semi-Automatic
DesignCustomized, Standard

We offer a complete range of Rising Film Evaporators of both short and long tube design.

In Rising Film Evaporators, due to the ascending force of the vapour bubbles, which are produced during boiling, the liquid and vapours flow upwards in a parallel flow. Simultaneously the vapour quantity also increase thereby forming a "Climbing" film on the walls of a tube. Due to this there is a high turbulence in the liquid and these evaporators are advantageous for heat sensitive, highly viscous and moderately scaling liquids.

The temperature difference in the rising film evaporators should be high between the heating chest and boiling chamber to ensure the circulation and formation of a climbing film.

These evaporators are flexible enough to be converted to Forced Circulation Evaporators.


TYPICAL APPLICATIONS -


  • Chemical Industry
  • Effluent Treatment Plants

FEATURES OF COMPRISING FILM EVAPORATORS
