The Importance of Evaporator Raw Material selection in Salt making Evaporator Design

Pharmaceuticals, foods and drinks, pulp and paper, plastics, polymers and resins, inorganic salts, acids, bases, and a host of other products are all processed using evaporators. Evaporators come in a variety of shapes and sizes, and which one is suitable for a given application is determined by the product’s characteristics and desired outcomes. AlaquaInc is the evaporators supplier in the USA for all kinds of processing equipment for various processing industries.

Two sources that salt is obtained from are rock salt and brine. Rock salt, also known as halite, is literally crystallized salt. That is the product of ancient seas evaporating millions of years ago. The United States, Canada, Germany, Eastern Europe, and China all have large reserves of rock salt. Salt domes are formed when pressure from deep inside the Earth pushes vast amounts of rock salt to the surface. Salt domes can be located along the Gulf Coast of Texas and Louisiana in the United States.

Brine is saline water with high salt content. The ocean is the most apparent source of brine, but it can also be derived from salty lakes like the Dead Sea and underground salt water ponds. Austria, France, Germany, India, the United States, and the United Kingdom all have large brine deposits. Brine may also be created artificially by dissolving mined rock salt or pouring water into rock salt wells.

Natural brines still have other ingredients dissolved in them in addition to salt. Magnesium chloride, magnesium sulphate, calcium sulphate, potassium chloride, magnesium bromide, and calcium carbonate are the most common. These compounds may be as valuable as salt in terms of commercial value. Rock salt may be completely pure or contain trace quantities of these compounds, as well as rocky impurities like shale and quartz.

However, additives are normally blended in with table salt. To add the trace element iodine to the diet, much table salt is iodized. This aids in the prevention of goitre, a thyroid gland condition. A small amount of potassium iodide is added to include iodine. Table salt also contains trace amounts of chemicals that prevent it from absorbing water and caking. Magnesium carbonate, calcium silicate, calcium phosphate, magnesium silicate, and calcium carbonate are examples of these compounds.

The raw material selection and technical specification requirements for evaporators for salt industry are far higher. Corrosion can occur very quickly after service if the specification is not reasonable or the raw materials are not chosen properly. What are the most important technological considerations when designing a salt evaporator? Monitor the uniformity and particle size of the salt crystals by extending the evaporator washing cycle.

Our company is focused on high technology evaporator design with centrifugal steam compressor. The MVR Evaporator can reduce fresh steam consumption by using lower cost electricity.

LH Evaporator has rich evaporator design experience. We can provide a turnkey solution not only for the MVR evaporator used in salt processing, but also for a variety of other applications such as pharmaceutical evaporation, milk powder evaporation, waste water disposal, sugar mill production, and so on.
