treatment of dust and gases polluted flows.
The main installations have been done for the treatment of flue gases coming from industrial process, therefore characterized by high concentration of specific pollutants.

For example, Donau Carbon realized plants for the treatment of flue gas produced during processing of materials for telecommunications, able, therefore, to capture very light dusts and strongly acid vapors.

The flue gases produced by production process contain very light dusts (less than 1 micron), hydrochloric acid and chlorine.

The polluted flow is maintained hot in order to remove the dust with special designed bag filters and then cleaned with basic reducing solution, by means of an high efficiency scrubber.

The aggressivity of flue gases needs the employ of materials resistant to corrosion and temperature.
This emission is included in the most restrictive limits requested by laws.

We offer different type of concentrators for the depuration of polluted air with low solvent concentration (< 1 g/m3).
This technology allows to reduce of 10-15 times the flow polluted by solvent, increasing the concentration and reducing the management costs.

Donau Carbon 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!
It is composed of a series of preassembled modules, tailor-made according to Customer layout, solvent laden flow rate, quality and concentration.
