Our investments in innovation and development lead to the creation of projects and patents capable of changing chemical production for the better.
Esseco Industrial looks at chemical production with a constant eye for the circular economy, thus recovering materials that would otherwise be waste, and introducing innovative energy recovery processes capable of drastically reducing the carbon footprint.
Since 2020, the Sodium Hydrosulphate / Sodium Dithionite production plant has been the first prototype developed and installed following the Esseco patent. Sodium Hydrosulphate / Sodium Dithionite is an important reducing agent used in the chemical, textile, and paper industries. The Esseco patent outlines an innovative production process.
Compared to the more common Mitsubishi process, the Esseco patent provides for the purification of mother liquors through the separation of Sodium Thiosulfate Pentahydrate, which is then reused in the production cycle.
This generates a drastic reduction in energy impact and the substantial elimination of environmental impact.
European regulation (2005/396/CE) has set the maximum acceptable level of chlorate in food at 0.01 mg/kg. Altair Chemical, in its Saline di Volterra (PI) plant – the first in Europe to switch to membrane cell technology as early as 2008 – has patented an industrial process for the dechlorination of KOH (caustic potash).
The plant is capable of destroying all the quantity of the chlorate compound KCIO3 during the electrolysis of KCI brine: by acting on the raw material (the brine), its finished product (KOH) is purified.
This allows the production of healthy products suitable for all consumers.
