double effect evaporation system. See video of system operating at http://www.youtube.com/watch?v=Y6J52r-maPE. Capacity based on a brine stream at 24% to 50% strength. Feedstock of 32,000 lbs/hr(normal operating) or up to 50,000 lbs./hr. brine at ~ 20-25% NaBr is sent to the first effect, where it is strengthened to ~ 35% NaBr. The steam generated from this effect is used for heating on the second effect. Final target for brine leaving the second effect is 45-50% NaBr. The first effect (IPP Stock # 216077) (drum type)t is 2,000 gallon, and is manufactured by Paget. With a 400 sq.ft. "U" tube heater, this unit is operaing at 310 degrees F using 150# steam. The second effect is a modular, forced circulation system, designed by Swenson and manufactured by Four Corp. This effect is operating at atmospheric pressure and using the steam generated from the first effect to heat the second effect 838 sq. ft shell and tube heater(reboiler, IPP Stock # 216082). Overheads are condensed (IPP Stock # 216085). Product at ~ 50% NaBr is sent to storage. Circulation is acheived by a Goulds 6,000 gpm centrifugal pump.

After the 4th evaporator the product is fed through a heat exchanger, where it cools the product to between 50 deg C and 70 deg C, water is used as a cooling medium, from there the product goes to storage tanks (not available) Pressure: 10 bar (145 psi).

Evaporators are used to concentrate a solution, separating the vapor from the solution. All evaporation equipment contains a heat exchanger for heating the process solution and a means to effectively separate the vapor from the residual liquid, called a vapor separator. Evaporator performance is rated by Lbs per hour or Kg per hour of evaporation. The greatest increase in steam economy is achieved by reusing the vaporized solvent. This is done in a Multiple Effect Evaporator by using the vapor from one effect as the heating medium for another effect in which boiling takes place at a lower temperature and pressure. Another method of increasing the utilization of energy is to use a Thermo Compression evaporator, in which the vapor is compressed so that it will condense at a temperature high enough to permit its use as the heating medium in the same evaporator. This type is also called a MVR or mechanical vapor recompression.
Short tube vertical evaporators are natural circulation evaporators. These units consist of short tubes 4-6 feet long and 2” to 4” in diameter set between two horizontal tube sheets that span the evaporator body diameter. The tube bundle contains a large circular down comer that returns concentrated liquid above the top tube sheet to below the bottom tube sheet for product withdrawal. The driving force for flow of liquid through the tubes is the difference in density between the liquid in the down comer and the tubes.
Long tube vertical evaporators accomplish more evaporation than in all other types combined. They are also natural circulation evaporators. They are also categorized individually as rising film, falling film, and rising/falling film types. Basically these units consist of a vertical single pass shell and tube heat exchanger discharging into a relatively small vapor head. Tube length is typically12’ to 36’; and the tube diameters are from 0.75” to 2” OD. Units may be once through or recirculating, depending upon the application. Long tube evaporators are the most economical design.
Forced circulation evaporators are made in a variety of arrangements for services where the feed and/or product liquor has a tendency to salt or scale and where the viscosities of the solutions are so high that natural circulation is not feasible. Force circulation is achieved by using pumps. Forced circulation leads to high tube side velocities and higher heat transfer coefficients and smaller heating surfaces. The pump withdraws liquor from the flash chamber and forces it through the heating element back to the flash chamber. Circulation is maintained regardless of the evaporation rate so this type of evaporator is well suited to crystallizing operations where solids must be maintained in suspension at all times.
Thin Film or Wiped Film are agitated evaporators - essentially a large diameter jacketed tube, in which the product is vigorously agitated and continuously removed from the tube wall by scraper blades or wipers mounted on a shaft rotating inside the tube. The material to be processed is continuously spread as a thin film on the tube walls by the mechanical agitator. This permits processing of extremely viscous and heat sensitive materials, as well as products that crystallize. The heating medium may be steam or hot oil on the jacket side.
