Extraction of salt from sea water is a process by which salt is removed from the seawater. Salt extraction has been used for centuries, but it has become increasingly popular as more people have become aware of its many benefits. Not only is salt an essential ingredient in our food and culinary applications, but it is also an essential component in industrial processes and products. The extraction of salt from seawater is done by boiling or evaporating the sea water until only the salt crystals remain. The salt crystals are then harvested for various uses. This process can take place on a large scale or on a small scale depending on the need for salt.
Benefits of Salt Extraction
The benefits of extracting salt from sea water are plentiful. For one, it provides an alternative to traditional mining of salt deposits, which can be costly and damaging to the environment. With salt extraction from sea water, there is no need to disturb land or use potentially hazardous chemicals during the mining process. Additionally, salt extracted from sea water tends to be of higher quality than mined salt, making it more valuable and sought-after. In addition to the environmental benefits, extracting salt from sea water is an excellent way to provide local economies with a sustainable source of income. In some parts of the world, coastal communities rely on salt extraction as their primary source of income. By providing a sustainable source of salt, these communities can build more prosperous futures.
Finally, salt extraction from sea water can have a positive impact on human health. Many coastal communities rely on fish and other sea life as a source of food, which can contain high levels of salt. By extracting and removing the salt from the sea water, the fish can remain healthy and safe for consumption. All in all, there are numerous benefits to extracting salt from sea water, making it a profitable and sustainable business.
Indian Market Outlook
India ranks third in the production of salt in the world next to USA and China. The Average annual production is about 20.31 million tonnes against the average annual world production of 240-250 million tonnes. Worldwide about 25 million tons of salt are used for edible purposes and rest is used for non-edible and industrial purpose. Sea salt constitutes about 70% of the total salt production in the country. Salt manufacturing activities are carried out in the coastal states of Gujarat, Tamil Nadu, Andhra Pradesh, Maharashtra, Karnataka, Orissa, West Bengal Goa and hinter land State of Rajasthan. Among these States only Gujarat, Tamil Nadu and Rajasthan produces salt surplus to their requirement. These three states produce about 70%, 15% and 12% respectively of the total salt produced in the country and cater to the requirement of all the salt deficit and non-salt producing states.
Global Market Outlook
The global salts market size was estimated at USD 15.3 billion in 2021 and it is expected to reach around USD 26.8 billion by 2030, poised to grow at a compound annual growth rate (CAGR) of 6.43% over the forecast period 2022 to 2030. Sodium chloride is derived by using seawater and rock salt for its extraction. The salt is used in agriculture, water treatment, de-icing, chemical processing. When it comes to the usage of industrial sales for the chemical industry it is used in the production of chlorine caustic soda and ash soda. Caustic soda is used in the production of paper and pulp, detergents and soap, chemical products and petroleum products. The demand for industrial salt is expected to grow in the coming years due to the manufacturing of caustic soda and chlorine on a large scale. The demand for the product is expected to grow in the coming years as it is used in many industries. Agriculture chemical processing and water treatment are the major applications of industrial salts. The industrial salts market is expected to grow well in the coming years as there is no other alternative which is cost effective.
Conclusion
The extraction of salt from sea water is a booming business because it provides a much-needed resource for many different industries and individuals, it is environmentally friendly, and it is cost-effective.
