THE FIRST SODIUM HYPOCHLORITE FACTORY IN THE CANARY ISLANDS

The first sodium hypochlorite factory in the Canary Islands, Biomca Química, was inaugurated on 11 May 2016. The President of the Canary Islands, Mr Fernando Clavijo Battle, and the President of the Cabildo Insular de Tenerife, Mr Carlos Enrique Alonso Rodríguez, attended.

The Mayor of the Santa Cruz de Tenerife City Council, Mr. José Manuel Bermúdez Esparza, the President of the Santa Cruz de Tenerife Port Authority, Mr. Ricardo Melchior Navarro and the Subdelegate of the Spanish Government in Santa Cruz de Tenerife, Ms. María del Rosario Cabrera Guelmes, also attended the event.

ELECTROLYSIS WITH MEMBRANE CELLS

The chlorine that is used to produce sodium hypochlorite is made through cell membrane electrolysis, regarded as the best available technique for this activity, as it represents the most innovative and efficient technology from the energy consumption standpoint.

CAPACITY TO INCREASE PRODUCTION

The plant has been designed for an annual sodium hypochlorite production of over 27,000 tons. The factory is currently operating at 66% of its capacity, this means it is supplying around 17,000 tons a year.

About Us

BIOMCA QUÍMICA

BIOMCA QUÍMICA is a company from the Special Canary Islands Zone (ZEC) established in 2014 in Santa Cruz de Tenerife with the purpose of making sodium hypochlorite. The company inaugurated the first sodium hypochlorite factory in the Canary Islands on 11 May 2016, capable of producing more than 27,000 tons a year to supply the needs for this product on the islands. The facilities are located on a plot of land within the Free Trade Zone in the Santa Cruz de Tenerife port fishing dock, where some 6 million euros and nine months of work have been invested for its construction.

What we do

Sodium hypochlorite is a universal disinfectant which, due to its properties, is highly effective in combatting all kinds of microbes. It is a clear solution with a basic nature, a light yellowish colour and a distinctive odour.

Sodium hypochlorite solutions are inherently unstable and start to decompose from the very moment they are prepared, and continue to do so until they have completely decomposed. If appropriate precautions are taken, the decomposition rate of sodium hypochlorite solutions can be controlled to the extent that relatively stable solutions can be prepared.

Process

How we do it

Membrane electrolysers produce gaseous chlorine (Cl2), sodium hydroxide (NaOH) and gaseous hydrogen (H2), from the electrochemical decomposition of a sodium chloride (NaCl) aqueous solution, also called "brine", and from the electrochemical decomposition of water by passing electrical energy in the form of direct current.

2 NaCI + 2 H2O = 2 NaOH + Cl2 (gas) + H2O (gas)

Both the chlorine gas generated by the electrolysers as well as the residual chlorine from the rest of the process is absorbed with sodium hydroxide in the chlorine absorption unit, with the resulting production of sodium hypochlorite as a by-product, according to the following reaction:

Cl2 + 2 NaOH = NaClO + NaCl + H2O
