Methods of production of caustic soda

Caustic soda production

Caustic soda, caustic soda, caustic soda, caustic soda and other synonyms of the substance NaOH - is the most common substance in the world of alkaline origin. 

Various enterprises of the chemical industry produce about 57 million tons of this product per year. In this article, we will take a closer look at production methods, as well as the largest players in this market.

Caustic is used in many areas of production and in everyday life, while it is not inferior in its characteristics and actions to many expensive chemicals of various brands. 

Caustic production methods

The production of caustic soda is carried out by many different methods, among which the chemical and electrochemical methods stand out . The chemical option for producing caustic soda includes lime, ferritic and pyrolytic, which are currently practically not used due to the high consumption of energy carriers and the low quality of the final product.

The chemical method has been replaced by a more efficient and less costly electromechanical method for making caustic soda, which includes three main options:

Variants of the electromechanical production method:

  • mercury is based on the process of electrolysis with a mercury cathode, as a result of which pure sodium hydroxide is obtained without impurities;
  • the diaphragm method is the simplest in the organization of the caustic production process and allows the presence of impurities in the composition of soda;
  • the membrane method requires complex installations and automation systems in the production of sodium hydroxide.

Each of the options for obtaining caustic soda in the chemical industry has its own characteristics, positive and negative sides.

So the most effective way to obtain a pure product - mercury, is being replaced by the other two due to high safety requirements at work.

Despite the high cost of the processes, the membrane method is gaining popularity, as a result of which purified caustic soda is obtained.

Can you make caustics at home? How to make caustic at home:

Caustic home

To clear a blockage in sewer pipes or bleach clothes, as well as clean kitchen utensils and an oven, you do not need to buy products from advertised brands, but you can use caustic soda and make it yourself. How to get caustic soda at home?

In order to make caustic soda, it is necessary to heat 1 kg of soda ash at a temperature of 30 ° C, and then dissolve in 4.5 liters of water. The soda solution is placed in a boiler, heated at a temperature of 60 ° C and a lime solution is poured in.

Stir thoroughly during cooking so that the process of converting ordinary soda into caustic occurs faster. In the process of making soda at home, it is important to follow safety rules when working with chemicals.

Soda production plants

On the territory of Russia there are several factories for the production of caustic soda in various forms: granules, scales and liquid. They are located in different parts of the country. For example, the Nikokhim group of companies occupies a leading position among Russian enterprises for the production of caustic soda.

The largest caustic soda production site is Volgograd, where the main capacities for the production of solid caustic soda are concentrated. 

Abroad, the leaders in the production of caustic soda are China, South Korea and Iran, exceeding Russia by hundreds of thousands of tons in terms of production of caustic soda. Small volumes of caustic soda are produced in almost all countries. 

Our plant, thanks to its many years of experience in exporting products abroad, as well as extensive experience in participating in international exhibitions of chemical products and raw materials, has acquired a network of long-term partnerships and since 2019 has been supplying imported chemical products for its customers - Russian enterprises.

All supplier enterprises selected by our specialists meet environmental safety standards, are equipped with the latest production equipment and a modern base of treatment facilities. The products supplied to the Russian market by our enterprise have the highest quality parameters.
