Product category: Solvent recovery plants

Steam Regeneration

This process is employed in presence of water low soluble solvents (ex. Toluene, Exane) and mainly in rotogravure printing, adhesive tapes, rubber production, extrusion and coating industries.

Process description:

The solvent laden air is sucked from production by means of a fan, and after filtering and cooling, is sent to the adsoption section composed by adsorbers connected in parallel or in series.

When the carbon is saturated, the regeneration with steam takes place.

Hereafter mixture of water and solvent vapors produced is condensed and cooled.

The solvents not soluble in water (like toluene, hexane, chlorinated hydrocarbon) are separated from water by means of a decanter, while the organic fraction dissolved in water is removed through stripping with air or steam.

For further depuration of solvent, a distillation section can be employed.
The regenerated carbon is cooled and dried with air in closed circuit (Donau Carbon/Lurgi Aktivkhole patent).

Solvent Recovery Plant with Water Adsorption

This process uses water to recover high-boiling, totally soluble, solvents (ex. DMF).

Mainly it is employed in the synthetic leather, textile and elastic fabrics, on polyurethane basis, production fields.

Process description:

A water solution is fed at the top of a washing column, which inside is equipped with plates and/or with packing structured in counter flow with the solvent laden air stream.
The water solution with the solvent is recovered on the column bottom, and after concentration check up is fed to a storage tank to be distilled, in the factory same or at thirds.
As already said for the solvent recovery plants with activated carbon, Donau Carbon Technologies Srl can supply both the recovery system and the distillery.

Solvent Recovery Plants with Activated Carbon Adsorption

Donau Carbon Technologies Srl realizes solvent recovery plants with activated carbon adsorption in most different field, employing, according to the needs, processes with steam or nitrogen regeneration.

A distillation section, batch or multicolumns, working in pressure or vacuum, equipped with double effect heat recovery systems, and in case, a dehydration section with molecular sieves, usually completes the plant.

Due to our yearlong experience we developed, besides “standard” solvent recovery plants, also solutions on skid in compact and modular type:

DC-CSR (Donau Carbon - Compact Solvent Recovery)
The recovery plant is compact!
The picture shows a closed realisation, with curtain claddings, "container" style.
The civil works are reduced to a platform.
In case of need, it can be easily moved away and transferred to other locations.
The erection times are minimal, because the plant is supplied fully assembled.

DC-MSR (Donau Carbon Modular Solvent Recovery) )
The recovery plant is modular! Assembly of prefixed modules, fully filled up in factory, composed to comply with the different layout, recovery capacity, quality and solvent charge
