Research on Production Process and Application of Granular Alkali

Granular alkali is a common chemical raw material and widely used in metallurgy, textile, leather, paper and other industries. This paper introduced the production process and application of granular alkali, analyzed the market demand and Prospect of granular alkali, and put forward suggestions for further improving the production process of granular alkali and strengthening environmental protection measures.

I. Introduction
Granular alkali is an important chemical raw material and a form of sodium hydroxide with the chemical formula NaOH. Granular alkali is widely used in metallurgy, textile, leather, paper and other industries. It is an indispensable raw material in many industrial processes. With the development of China's industry, the demand for granular alkali is increasing constantly, and the granular alkali industry has also obtained considerable development.
II. Production process of granular alkali
The production process of granular alkali is mainly divided into electrolysis and NaCl method. Electrolytic method is to use the anode and cathode in the electrolyte cell to react, decompose NaCl aqueous solution into chlorine and NaOH, and then obtain granular NaOH through crystallization, ion exchange and other processes. The principle of NaCl is to mix NaCl and CaOH, obtain NaOH by heating reaction and generate gas, and finally obtain granular NaOH by filtering and drying.

III. Application of Granular Alkali
Granular alkali is an important chemical material and widely used in metallurgy, textile, leather, paper and other industries. In metallurgical industry, granular alkali is mainly used for aluminium smelting and non-ferrous metal smelting. In textile industry, granular alkali is the main material for bleaching cellulose fibers. In the leather industry, granular bases are used for bleaching and neutralization reactions in the leather processing process. In the paper industry, granular alkali is the main raw material in the paper bleaching process.
IV. Market demand and Prospect of granular alkali
With the continuous development of our industry, the demand for granular alkali is increasing. Especially with the increase of environmental awareness, a large number of organic solvents are used in traditional chemical processes.
