DEC IMPIANTI S.p.A. is a private corporation, focused on engineering and supply of turn key sustainable industrial VOCs and HAPs emission control systems for the flexible packaging, chemical, petrochemical and pharmaceutical industries. Backed with 75+ years of global experience, thanks to products of the highest quality, patented and/or innovative processes, with thousands of systems in operation, we are facing the global challenges, focusing on innovative sustainable technologies and research.
As worldwide market leaders in activated carbon solvent recovery systems (SRU), inert gas (nitrogen, N2) regenerated, DEC IMPIANTI has designed, engineered and delivered more units than any other competitor combined.
MEK | butanone | methyl ethyl ketone | solvent recovery
The DEC.RSG™ process is a hot nitrogen regeneration process for activated carbon solvent recovery units (SRUs): a safe and efficient process that avoids hot spots and fire on activated carbon. The DEC.RSG™ process is used to recover a variety of solvents, including ketones (e.g. MEK - methyl ethyl ketone, ACEK - acetone, CHXK - Cyclohexanone, MIBK - methyl isobutyl ketone, etc.).
The DEC.RSG™ process works by passing hot nitrogen through the activated carbon bed. The hot nitrogen heats up the activated carbon, which releases the adsorbed solvents. The solvents are then condensed and collected. A safe and efficient process that has been used to recover MEK streams, alone or in mixtures, since 30 years: it is the preferred process for recovering solvents from activated carbon beds. First installation of the SRU, nitrogen regenerated, for MEK recovery is dated back to 1992
DEC IMPIANTI leads the way in VOC recovery solutions. Our unrivalled technical expertise and experience in sustainable solvent recovery systems make us the world's leading contractor: no other entity has the same breadth and depth of experience or talented inert gas activated carbon solvent recovery engineering resource. This is reflected in our long-term alliances and service agreements with most of the industry's leading companies.
