Chemicals

Chlorine

Chlorine is produced by electrolysis of sodium chloride and water, initially as a greenish-yellow gas with a strong odor. For transportation and storage, it is liquefied into clear amber liquid. It can be transported in tank trucks and/or isotanks, as long as they are intended for shipping the product and equipped with safety devices. Chlorine has diverse applications, essential in industrial processes, drinking water and wastewater treatment. Also used in swimming pools for disinfection, ensuring safety. Its versatility and effectiveness make it essential in modern life.

Chemicals

Manufacturing process

Chlorine is produced by electrical current flowing through a pre-processed brine solution (common salt dissolved in water). This process is known as electrolysis. The other byproducts are caustic soda (sodium hydroxide or (NaOH) and hydrogen (H2). It is a liquefied gas and, for commercial purposes in that form, it goes through cooling, drying and compression stages. For each ton of chlorine, 1.1 ton of caustic soda and 0.03% tons of hydrogen are produced.

Chemicals

Where can chlorine be applied in our daily life?

It is used to manufacture PVC, chlorinated solvents and agrochemicals, being essential for the treatment of potable water, swimming pools, sewerage and as an intermediate input in the production of polyurethane.

hydrochloric acid, sodium hypochlorite and dichloroethane.
