Alaquainc Offer affordable Crystallization of types.


Alaquainc offer the frequently process on the heating pipe of heat exchanger crystallizing. Crystallization are a motion process in which the cool from pan dropping temperature. Differ from one another in the method by this case Super saturation in the swirling liquid near the surface and Produced by evaporation of the solvent. Which result in deposit on swirling suspended crystals? Super saturation is generating by evaporation.

Cooling crystallization from solution or the Evaporative

The processes is Alternative methods of cooling that not require a heat exchanger are flash cooling which involves  crystallizer evaporation of the solvent or direct cooling via insertion of a cold gas or with increasing stability of temperature. Crystallization of the liquid is cooled to a temperature below the equilibrium solubility.

In a cooling crystallization process the feed is cooled in a heat exchanger, but the heat exchanger can also be integrated in the crystallizer in the form of cooled tubes or plates. From the cooling needs to be done carefully to prevent nucleation on the cold surface of the heat exchanger, which will lead to encrustation. The lowest temperature in the system is at the surface of the heat exchanger. 

Basically measures to prevent this unwanted phenomenon is to reduce the temperature difference between the coolant and the Crystallizers cooling  solution, to increase the liquid velocity along the surface of the heat  level out the temperature difference over the length of the heat exchanger or to use a scraper to keep the surface of the heat exchanger free of solids.

In which implement that cooling the saturated solution will not result in a significant amount of crystals mention that evaporative crystallization is usually the preferred method when the amount of dissolved product decreases with less energy level. In the case of compounds with a low solubility the standard option is reactive crystallization/precipitation.
Evaporative Crystallization

The evaporation heat that has been added is in principle captured in the vapor stream. The Crystallizers evaporative are used industry to achieve solid-liquid separation. The crystallization evaporation of the solvent is resulting from the certain moment the concentration of impurities will become so high that they can influence the crystallization and/or the product purity. So that is process creates a vapor and a suspension of crystals in mother liquor. In this principle of energy can be recovered, but the energy will be available on a lower. This is possible to residual amount of product by recycling the mother liquor to the feed. If that is the case, mother liquor will still contain the equilibrium concentration of product.

Alaquainc Manufacture of Equipment for Crystallization System

Alaquainc method is a best crystallization used in some specialized cases. Crystallizers cooling in saturated solutions are allowed to cool in open tanks. Scraped surface of one type crystallizes is the Swenson-Walker crystallizes, Scraped surface crystallizers in which consists of an open trough 0.6m wide with a semicircular bottom having a cooling jacket outside.
An internal agitator is fitted with spring-loaded scrapers that wipe the wall and provide good heat-transfer coefficients. The crystals removed mother liquid is drained after a period of time and the. Difficult to control crystals size are Nucleation. Typically, labor costs are very high. The crystal-size distribution somewhat wide product generally used.
Also called a violator, this type of crystallizer is used in crystallizing ice cream and plasticizing margarine. Cooling water passes in the annular space the growing crystals on turning a slow-speed spiral agitator rotate and suspends. The break and blades pass close to the wall off any deposits of crystals on the cooled wall Double-pipe scraped surface crystallizer.
Circulating-liquid Crystallizers evaporative
Continuous oscillatory baffled crystallizer (COBCTM) the heated liquid then flows into the vapor space, where flash evaporation occurs, giving some super saturation. The vapor leaving is condensed. The suspension or magma of crystals is circulated out of the main body through a circulating pipe by a screw pump. The magma flows though a heater, where its temperature is raised 2-6 K. The saturated liquid is leaving then goes back as a recycle stream to the heater, where it is joined by the entering fluid. Also called Crystallizers Oslo the supersaturated liquid flows down the down flow tube and then up through the bed of fluidized and agitated crystals, which are growing in size.

Circulating-magma Crystallizers vacuum. Here super saturation is reached by evaporation. The crystal is larger settle out and slurry of Crystallizer and mother liquid is withdrawn as a product. The boiling occurs at the liquid surface heated liquor then mixes with body slurry and allowing controlled cooling profiles, e.g. linear, parabolic, discontinued, step-wise or For further information see oscillatory baffled reactor. The vapors leave through the top. A steam-jet ejector provides vacuum.
The circulating liquid is drawn by the screw pump down inside the tube side of the condensing stream heater. That offers plug flow under laminar flow conditions (low flow rates) with superior heat transfer coefficient this gives much better control over crystal size, morphology and consistent crystal products. The COBCTM is a tubular baffled crystallizer this causes super saturation in the swirling liquid near the surface, which deposits in the swirling suspended crystals until they leave again via the circulating pipe.

Try Alaquainc Evaporation Systems to Achieve a Sustainable and Effective Process

Evaporative system multiple effect

As we know that Evaporation is an effective method to minimize the volume of waste products. Our Plate evaporator systems are build in such a way to increase the effluent to its boiling point due to this reason the water get  evaporates and then condenses, obtaining a final concentrated product and water. The method of forced recirculation uses a pump to send the waste product through the evaporator in order to ensure that the heat transfer rates remain high and the adverse effects of fouling are at minimum level.

EVAPORATION SYSTEMS WITH CORRUGATED LONG TUBE:-For the evaporation of low viscosity effluents and waste having a reduced particle size, we use the K Series heat exchanger method, which in turn provides high heat transfer and good resistance.

These systems can be applied in these areas:-
  • sewage water
  • Effluents with low to medium viscosity
  • Low content of suspended solids
SYSTEMS OF EVAPORATION OF SCRAPED SUFFERFACE
For this we use the Unicus Series as an evaporator module for high contamination fluids with high viscosities. By concentrating the materials to a high percentage of dry solids, the risk of fouling and high viscosity becomes evident.

These systems can be applied in these areas:-
  • Effluents with high risk of soiling
  • Organic solids with high concentration of dry matter
  • High content of suspended solids
We use two technologies that maximize the use of energy, within our range of evaporation systems:
  1. MULTI-EFFECT EVAPORATION SYSTEMS

These systems combine several stages of evaporation. The steam obtained from a previous stage is used as a source of thermal energy for the resulting stage. Multiple stages can be combined to reduce the energy consumption required for the amount of evaporated water.
  1. SYSTEMS OF EVAPORATORS - THERMAL RECOMPRESSION
In the MVR configuration, the steam is sent to a compressor (where the pressure and temperature increase) and is used as a source of thermal energy in the evaporation process. In this configuration only electric power is used (to drive the compressor). In the TVR configuration, the steam can be mixed in a thermo compressor with the steam coming from the boiler, which generates a considerable energy saving.
