Safe Savings

 

Salt tends to cake when transported or stored without special additives. Up until now, this is usually prevented by adding ferrocyanide (also called YPS), a powerful anti-caking agent for salt which was developed by AkzoNobel in the 1950s. The additive prevents lumps forming and made it instantly ready for use in industry. 

However, ferrocyanide is not removed during brine purification. It decomposes into ‘free’ iron and cyanide when it enters the membrane electrolysis cell, components which can negatively affect the cell’s performance.

Setting a new standard
This is why we have now introduced AkzoNobel mTA-Salt – the latest innovation from our laboratories. It’s industrial salt with an eco-efficient anti-caking agent that could save up to 5% of a chlorine production plant’s total energy consumption. It’s a state-of-the-art liquid agent sprayed onto salt before transport to the customer.

Increased efficiency – minimal downtime
Extensive research and close monitoring in our own plants has confirmed the benefits of using AkzoNobel mTA-Salt:

• Cost savings, thanks to a reduction in power consumption up to 5%

• Iron contamination is prevented through constant high cell performance

• Less maintenance, thanks to increased cell lifespan:  
     - No iron contamination means less pinhole formation  
     - Fewer pinholes means less damage caused by caustic entering
       the anode compartment  
     - Less oxygen – that can reduce the anodes’ life – develops as a
       by-product

• Less downtime, increased production: forced shutdowns to clean membranes and cells from iron precipitation are reduced to a minimum

• Enhanced product quality: brine acidification no longer a problem

• Cost savings through waste reduction: less chlorate in return brine – and therefore in the purge – could even eliminate the need for an additional conversion unit 

Safer processes
Enhanced safety with less cost: highly-explosive nitrogen derivatives in the feed brine are reduced.

Better eco-efficiency
AkzoNobel mTA is an entirely biodegradable specialty chemical. It quickly decomposes in soil or water – it’s a ‘green’ product. And because it helps to save energy, it increases the eco-efficiency of the whole chlorine production process.
 
Tested… approved… ready
AkzoNobel has used around one million tons of mTA-Salt each year in its own Chlor-Alkali plants since 2005. During this time more than five million tons of salt have benefited from our mTA formulation. Now mTA-Salt is commercially available for the rest of the Chlor-Alkali world.
