Laboratory and product testing

De Nora’s laboratories are equipped with all the main instruments for characterization and tests on electrodes.

Our laboratories are designed to support the Research and Development activities as well as for providing support to the technical assistance to our customers in any application. The three location of the main labs are equipped with all the necessary instrumentation for electrode characterization and destructive and non-destructive tests on any kind of electrodes 

The best-known and more frequently used electrolytic process is the chlorine and caustic soda generation from a saturated sodium chloride solution that, today, contribute through two different processes – membrane and diaphragm – to most of the  80+ million tons of chlorine generated worldwide.

Chlorine and caustic soda generation from a saturated sodium chloride solution is the best known electrolytic process. Today the worldwide production of chlorine exceeds 80 millions tons, produced almost entirely through Ion Exchange Membrane process and in a smaller quantity via diaphragm process.

The same NaCl brine solution is used for the sodium chlorate generation, a product widely deployed in the paper industry for pulp bleaching; chlorine (without the concurrent production of  caustic soda) could also be generated via the electrolysis of a waste solution of hydrochloric acid resulting from TDI / MDI production.

A different (minor) industrial chlorine source is represented by the caustic potash production plants, where the used brine is a saturated solution of potassium chloride in water.
Different types of acids and bases (organic and inorganic) can be obtained from the so called “salt splitting processes“.
Hydrogen and oxygen generation is obtained through alkaline water electrolysis (AWE), a well-established technology that, thanks to recent innovation and improvement, is able to allow an economical route to green hydrogen using only renewable energy sources. This process, contributing to the world decarbonitazion and easing the future energy transition, is a possible using as electrolyte a sodium potash solution and has zero emission nor CO2 footprint.
For all these different process and technologies, De Nora provides solutions to offer competitive advantages in terms of power consumption and process yield allowing lower total cost of ownership (TCO).
