Falling Film Evaporator (FFE) Gentle evaporation for heat- sensitive products The falling film evaporator is a type of film evaporator which is used most commonly because of its wide operating range. A Falling Film Evaporator (FFE) is a vertical shell & tube type of heat exchanger with vapor- liquid separator (VLS) mounted at the bottom. The liquid to be concentrated is fed at the top of heated tubes and distributed in a way that it flows down on the inside surface of the tubes as at thin film. The liquid distributor at the top assures uniform liquid loading of all tubes. As the film gets heated, the vapors generated flow downwards through the tube bundle in co- current with the concentrate. The drag of the vapors increases the turbulence & improves heat transfer performance. Subsequently, the vapor phase is separated from the liquid phase in vapor liquid separator (VLS). Falling Film Evaporator Advantages: Applications: • High heat transfer coefficients • Particularly suited for temperature- • Short residence time on the heated tube surface sensitive products • Can be used from smallest evaporation • Recovery of solvents & alcohols capacities • For low viscous products • Little space needed • Suited for products with low fouling • Low pressure drop tendency • Suitable for operation under high vacuum • Separation of multicomponent mixtures • High evaporation ratios • Concentration of starch products and • Low susceptibility for fouling derivatives in the starch industry • Suitable for GMP applications • Concentration of spent liquor in the • Single pass or with recirculation pulp industry • Process vapors and liquid flow co-currently or counter-currently • Chemical industry • Petrochemical industry • Several evaporator stages are possible in one apparatus • Polymer industry Rising Film Evaporator (RFE) Evaporation technology for concentration of moderately heat- sensitive liquids The rising/climbing film evaporator is a type of film evaporator which can achieve moderate evaporation, suitable for high viscosity and heat sensitive materials. A Rising Film Evaporator (RFE) is a vertical shell & tube type of heat exchanger with vapor-liquid separator (VLS) mounted at the top. The rising film evaporator operates with the density difference of liquid / liquid-vapor mixture inside the tubes. The liquid to be concentrated is fed at the bottom of heated tube bundle. As the liquid feed receives the heat, the vapors generated lift the liquid upwards. The vapor and balance liquid are separated in vapor-liquid separator (VLS) Rising Film Evaporator Advantages: Applications: • Shorter residence time • Juice concentration & food processing • High evaporation ratio • Polymer production • Suitable for evaporation of a wide range of liquid • thermal desalination, concentrations • Pharmaceuticals • High tube velocity minimizes fouling • Solvent recovery • System may be turned down without loss of efficiency or effectiveness • Waste water & Effluent treatment • Able to achieve high concentrations at low temperatures • Suitable for materials with higher evaporation temperature • Suitable for low to medium viscosities liquids • Suitable for heat sensitive materials • Suitable for foamy liquids & liquids with suspended solids Forced Circulation Evaporator (FCE) Forced Circulation Evaporator with axial flow pump experience reduced scaling The forced circulation evaporator is designed for liquids with a high solids content, high viscosity & tendency to foul. A Forced Circulation Evaporator (FCE) has Horizontal or vertical shell-and-tube heat exchanger as the calandria, with flash vessel/separator & a circulation pump for circulation of slurry through the tubes. Use of axial flow pump ensures good velocity in the tubes with minimum power requirement. Forced circulation leads to high tube side velocities (6-18 ft/s), and hence higher heat-transfer coefficients and smaller heating surfaces. Boiling in the forced circulation evaporator is suppressed in the heat exchanger by backpressure and takes place when the liquid enters the flash vessel/separator. Forced Circulation Evaporator Advantages: Applications: • Suitable for highly viscous, scaling & salting • Spent wash from distillery liquids • Corn Steep Liquor • Suitable for waste water with high suspended solids • Liquids with high tendency of fouling • Fouling is minimized due to high liquid velocities • Highly viscous liquids & suppressed boiling in the tubes • Effluent Treatment Plants • High tube side velocities can be achieved • Polymers • Higher heat-transfer coefficients • Food products • Easy installation and move, skid mounted with • Pharmaceuticals small footprint • Optimally suited as crystallizing evaporators for saline solutions. • Axial flow pump ensures good velocity in the tubes with minimum power requirement • Robust and reliable process • Low energy consumption and minimum need of maintenance Multiple Effect Evaporator (MEE) Multiple-effect evaporators (MEE) maximize steam economy as vapor generated from one effect is used to heat another.

(Honours) 1997 --------- Heat Transfer and Fouling in Film Evaporators with Rotating Surfaces ii ABSTRACT A study was made on the heat transfer and fouling in thin film evaporators with rotating surfaces. Both theoretical and experimental studies were carried out, order to gain a better understanding of these evaporators and their design in principles, so that this type of evaporator could be effectively used in an on-farm milk evaporation system. By using Nusselt-type assumptions, a theoretical model, which was used to predict the liquid film thickness and heat transfer coefficients on the rotating cone, was developed. The theoretical equations obtained revealed basic relationships between the variables and provided a fundamental knowledge of the liquid flow and heat transfer in thefilm evaporators with rotating surfaces. The experimental studies on heat transfer were conducted on a Centritherm evaporator, which is available commercially (400 half cone angle), a specially made cone evaporator (100 half cone angle) and a falling film evaporator with a rotating tube. Variables evaluated were the rotating speed, the cone angle, the feed flow rate, the evaporating temperature, the temperature difference between the steam condensing and the liquid evaporating temperatures, and sugar concentration when sugar solution was used.

Conclusion Glossary Bibliography and Suggestions for further study Summary Forced-circulation evaporators can be regarded as the most versatile type of evaporators in the range of possible applications. They are used mainly to evaporate media containing solids brought in by the feed or crystallized during evaporation. In addition, forced-circulation evaporators have large advantages, if the feed contains substances which UNESCOcause encrustations. – EOLSS The minimizationSAMPLE of the energy consumption forCHAPTERS heating and the cooling water quantity for condensation of the vapors is only one of the advantages of using multiple-effect forced-circulation evaporators, as the same effect can often also be reached by using an evaporator with a mechanical vapor recompression, if the boiling point elevation of the final product solution is not excessively high. A plant consisting of multiple-effect forced-circulation evaporators is, however, very flexible for the optimization of crystallization processes.

  • 14.6. Evaporator Operation

    802 CHEMICAL ENGINEERING Enthalpy of steam saturated at 101.3kN/m2 = 2676 kJ/kg. Thus: energy from steam = (2764 − 2676) = 88 kJ/kg or 0.088 MJ/kg and: steam required = (0.489/0.088) = 5.56 kg/kg evaporation at a cost of: (0.01 × 5.56)/10 = 0.0056 £/kg water evaporated and hence: the Diesel engine would be used for driving the compressor. 14.6. EVAPORATOR OPERATION In evaporation, solids may come out of solution and form a deposit or scale on the heat transfer surfaces. This causes a gradual increase in the resistance to heat transfer and, if the same temperature difference is maintained, the rate of evaporation decreases with time and it is necessary to shut down the unit for cleaning at periodic intervals. The longer the boiling time, the lower is the number of shutdowns which are required in a given period although the rate of evaporation would fall to very low levels and the cost per unit mass of material handled would become very high. A far better approach is to make a balance which gives a minimum number of shutdowns whilst maintaining an acceptable throughput. It has long been established(18) that, with scale formation, the overall coefficient of heat transfer may be expressed as a function of the boiling time by an equation of the form: 2 1/U = atb + b(14.11) where tb is the boiling time. If Qb is the total heat transferred in this time, then: dQ b = UAT dtb and substituting for U from equation 14.11 gives: dQ AT b = (14.12) 0.5 dtb (atb + b) Integrating between 0 and Qb and 0 and tb gives: 0.5 0.5 Qb = (2AT /a)[(atb + b) − b ] (14.13) There are two conditions for which an optimum value of the boiling time may be sought–the time whereby the heat transferred and hence the solvent evaporated is a maximum and secondly, the time for which the cost per unit mass of solvent evaporated is a minimum.

    Chapter 21: Evaporation – Principles, Types Of

    CHAPTER 21: EVAPORATION – PRINCIPLES, TYPES OF EVAPORATORS Evaporation is an operation used to remove a liquid from a solution, suspension, or emulsion by boiling off some of the liquid. It is thus a thermal separation, or thermal concentration, process. We define the evaporation process as one that starts with a liquid product and ends up with a more concentrated, but still liquid and still pumpable concentrate as the main product from the process. There are actually a few instances where the evaporated, volatile component is the main product, but we will not discuss that here. In most cases it is essential that the product be subject to minimal thermal degradation during the evaporation process, requiring that temperature and time exposure must be minimized. This and other requirements brought on by the physical characteristics of the processed product have resulted in the development of a large range of different evaporator types. Additional demands for energy efficiency and minimized environmental impact have driven development toward very innovative plant configurations and equipment design. In the field of thermal separation / concentration technology, evaporation plants are widely used for concentration of liquids in the form of solutions, suspensions, and emulsions. The major requirement in the field of evaporation technology is to maintain the quality of the liquid during evaporation and to avoid damage to the product. This may require the liquid to be exposed to the lowest possible boiling temperature for the shortest period of time. This and numerous other requirements and limitations have resulted in a wide variation of designs available today. In almost all evaporators the heating medium is steam, which heats a product on the other side of a heat transfer surface.
