PLANTS FOR THE PRODUCTION OF SODIUM HYDROXIDE (caustic soda) BY ELECTROLYSIS

At Welysis, our specialisation focuses on the construction of electrolysis plants for the production of caustic soda, also known scientifically as sodium hydroxide or sodium hydroxide. We focus on designing and developing facilities that allow us to obtain caustic soda in concentrated solutions, optimising the processes to achieve maximum efficiency and operational safety.

The concentration we obtain is 32% by default. However, it is possible to install a soda concentrator with a supplement to obtain a concentration of 50%.

Quality and safety are paramount in our caustic soda production plants. We implement advanced electrolysis technologies and rigorous quality controls to ensure that production meets the highest standards. In addition, our facilities are designed to minimise the risks associated with handling highly corrosive substances, ensuring a safe environment for operators.

Caustic soda is an essential compound in many industries. Some of its most important applications include:

• Pulp and paper manufacturing, where it is used for bleaching and pulp processing.
• The chemical industry, as a reagent in the production of various compounds.
• Water treatment, for acid neutralisation and pH adjustment.
• The textile industry, in the mercerisation process to improve the quality of fabrics.
• The production of detergents and soaps, thanks to its properties as a cleaning and degreasing agent.

Welysis’ commitment to our customers goes beyond the construction of the plant. We offer a complete package of post-construction services including technical training for personnel, preventive and corrective maintenance, and ongoing process improvement advice. Our goal is to ensure that caustic soda plants not only meet initial expectations but continue to operate efficiently and safely over time.

All Welysis facilities are automatically integrated into WIN (Welysis International Network), a collaborative environment where evidence-based experience, wisdom and best practices are exchanged. WIN merges an inter-facility communication mechanism with data analysis through Big Data, with the aim of perfecting procedures that have a direct impact on the improvement of the facilities and the well-being of the communities in which they operate.
