Industrial salt

What is industrial salt?

Industrial salt is sodium chloride (NaCl) produced for industrial applications, with a purity ranging from 99.4% to more than 99.95% NaCl depending on the type. It is obtained via three production methods: vacuum evaporation (the purest form, suitable for high-grade process applications), solar evaporation, and underground mining (rock salt). For industrial process applications, vacuum salt is used almost exclusively, due to its consistent grain size, low levels of calcium, magnesium and sulphates, and reproducible batch composition.

Industrial applications of industrial salt

Industrial salt plays a key role in countless industrial processes. In the chemical industry, it is used as a primary raw material for chlor-alkali electrolysis, producing chlorine, caustic soda and hydrogen, as well as for the production of soda and other sodium compounds. In industrial water treatment, it is indispensable for the regeneration of ion exchangers in water softeners, demineralisation installations, and condensate polishing units at steam boilers and cooling systems. In this way, it plays a central role in refineries, power plants and chemical installations that produce process water, boiler feed water and cooling water.

Industrial salt is also a fixture in industrial cleaning processes. In CIP systems (Cleaning in Place) in food production, breweries, the dairy industry and pharmaceutical production lines, it is used for the regeneration of water softeners that supply the process water. In food production itself, it functions as a technological auxiliary or raw material in brine baths, brine solutions and fermentation processes. The pharmaceutical and biotechnology industry uses it in production processes where low levels of heavy metals and microbiological purity are essential.

In addition, industrial salt finds its way into textile dyeing and tanning as a process raw material in dye and tanning baths where a constant ionic strength is required. In the glass, ceramics and metal industries, it is used as a smelting and process raw material and in baths for surface treatment. The oil and gas industry applies it as a component in drilling fluids and completion brines, while manufacturers of detergents and industrial chemicals use it as a raw material and as a regulator of pH and density.

Quality and specifications

In the process industry, consistent quality matters more than temporarily high quality. A deviation in calcium, magnesium or sulphate content can lead to membrane fouling, reduced electrolysis yields or deviations in end products. Our industrial salt meets strict specifications, and upon request each delivery is accompanied by a Certificate of Analysis (CoA) with the exact batch specifications. Batch traceability is guaranteed from production to delivery.

Our customers choose Nederlandse Zouthandel for the consistent batch quality delivered to fixed specifications, so that no surprises occur in your process. Our specialists support you with technical advice in selecting the right grade for your specific process requirements, and supply reliability is guaranteed during peak demand. You have one dedicated point of contact for planning, logistics and quality.
