Welysis products

Welysis specializes in designing, engineering, assembling, and installing scalable and modular electrolysis plants for chlor-alkali production. Their facilities are engineered to accommodate varying production capacities, ranging from small-scale operations producing 2 to 4 tons of chlorine per day to large industrial operations with outputs of up to 30 tons per day. The plants produce essential chemicals including sodium hypochlorite, hydrochloric acid, and hydrogen, integral to industries like disinfection, bleaching, plastics production, and metal processing. The units comply with stringent international standards, ensuring continuous and reliable operation while maintaining high product purity. By facilitating in-house production, transport costs and regulatory restrictions associated with hazardous materials are minimized. The installations are designed for a lifespan of at least 25 years. Additionally, Welysis offers comprehensive services including commissioning, training, maintenance, and continuous improvement through its international network, facilitating optimal plant performance.

Thanks to our internal research team composed of engineers and chemists, at Welysis, we develop exclusive and innovative technologies. We adapt and incorporate the latest trends in water treatment technology on the market. Our RDi team works constantly to always offer the highest standards of technological innovation. We design and develop our plants to have an excellent return on energy and investment, to make the products produced competitive in the market, and to have minimal or zero environmental impact.

Sodium hypochlorite is primarily used for water purification due to its strong fungicidal and bactericidal properties. It is also widely applied in bleaching textile fibers and disinfecting environments like swimming pools. Given its escalating use and market growth, local production via electrolysis plants is becoming essential due to handling risks and transportation restrictions. The production process ensures quality by maintaining sodium hypochlorite concentration between 12-15% active chlorine, limiting sodium hydroxide and sodium chlorate levels to prevent unwanted reactions, and controlling impurities like iron and nickel to preserve product integrity. The production plants incorporate advanced technologies for process control, waste minimization, and by-product recycling, enhancing safety and efficiency. These plants also comply with rigorous international safety regulations to protect workers and the environment.

Welysis specializes in the production of high-purity hydrochloric acid through advanced electrolysis technology. The process begins with hydrogen and chlorine gases that undergo combustion, followed by absorption of the resulting hydrogen chloride gas in water, resulting in hydrochloric acid with a 32% concentration. Strict quality controls ensure the acid's suitability for industries like pharmaceuticals, electronics, and chemicals, maintaining impurities such as iron and heavy metals at minimal levels. The facility's technology ensures continuous high-quality output with systems that monitor operational conditions like pH, conductivity, and temperature in real-time, and employs strategies for waste minimization and by-product recycling. A strong focus on safety and compliance with international standards ensures that both personnel and environmental safety are prioritized throughout the production and handling processes.
