MIBK | methyl isobutyl ketone | solvent recovery | activated carbon

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.).

Methyl isobutyl ketone (MIBK), also known as 4-methyl-2-pentanone, is a versatile solvent with a wide range of applications. Its properties make it useful in various industries: coatings, resins, adhesives, as an extraction agent and as an intermediate in various organic synthesis.

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 cyclohexanone 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 cyclohexanone recovery is dated back to 1992.
