VEGETAL ACTIVATED CARBON FOR HYDROCARBONS ABATEMENT AND RECOVERY 

ACTIVATED CARBON AND ACTIVATED CARBON PLANTS RELATED SERVICES 

As you surely know, vegetal activated carbon is since far along disappeared from the market, and the actual activated carbon present on the market is all from mineral origin. 

Old Customers of vegetal carbon well know the advantages of this carbon, that was the best medium for solvent recovery and gas purification, advantages reassumed as follows: 

LOWER DENSITY OR A LOWER WEIGHT IN A SPECIFIC VOLUME: 

as all plants are designed with a specific volume of carbon to assure the contact time, this means that a vegetal carbon bed has a lower weight and, for consequence, a lower specific cost. 

VERY HIGH ATTRITION RESISTANCE: 

after a 80 minutes test the vegetal carbon still has 98 % of nominal dimension, mineral carbon has only 92 %, this means no carbon sieving and adding after only two-three years of use. 

HIGHER THERMAL SHOCK RESISTANCE: 
this means less disgregation in particles and longer carbon life. 

GREATER ACTIVATED SURFACE: 

more then 1300 m2/g of B.E.T. that has to be compared with the usual lower figure of a mineral carbon. 

ISOTHERM EQUILIBRIUM OF 46 % OF BENZENE ADSORPTION AT 0,9 p/p1 AND 32% AT 0,01: 

unbeatable adsorption figures for a mineral carbon, especially at low concentration. 

MORE RETENTIVITY AND LESS STEAM CONSUMPTION: 

vegetal carbon allows a bigger solvent load in adsorption and has a lower steam demand for its regeneration. 

LESS ACIDIFICATION POWER, LESS HYDROLYSIS - BOTH FOR STEAM AND HOT GAS - AND LOWER BYPRODUCTS (LIKE ACID) FORMATION DURING THE REGENERATION: 
this means 3 time less acid formation and high boiling byproducts. 

CERTIFIED ASH AND HUMIDITY: 
for vegetal carbon no dust or water is sold at carbon's price. 

The vegetal carbon was mainly produced in Europe by the German Degussa. After having bought Degussa, the American Chemviron has shut down the production facility in Germany and the vegetal carbon more or less has disappeared from the market, enforcing Customers to buy far-east produced activated carbon of mineral origin.   

 

Omniatex is glad to inform you that a newest facility for the production of vegetal activated carbon, with Degussa experience and know-how, has entered production in Germany and our Society is the only one distributor in Italy of the new vegetal highly activated carbon, with also the possibility to sell the carbon in other Countries. 

The vegetal activated carbon is produced with a row material that is strictly controlled and with a quality resulting in an highly activated carbon, with the use of a natural binding agent, of natural origin, extremely resistant to the water. 

See the production cycle of the vegetal carbon in the following block diagram: 

 

The new production facility, with a fully integrated production cycle, has also been granted with all DIN EN ISA Certifications, including the 14000 for the environment respect. 

State-of-the-Art production shop 

The R&D Department and his fully equipped Laboratory allows any kind of research and development for a prompt answer for the better solution to any Customer's problem. 
Adsorption/Desorption test Thermogravimetric test
 
All the above listed advantages have already been verified and certified, for the new vegetal carbon, by field-tests on plants in operation in Germany and in Italy, for several solvents.
 
With this new opportunity Omniatex can also supply any kind of service required by any activated carbon recovery plant, as:
  • Emptying of old carbon from the vessel
  • Check and full cleaning of the carbon support
  • Check and full cleaning of the interior of the vessel
  • Check and repair of the carbon support
  • On site modification of the vessel
  • On site modification of the carbon support
  • Filling of the vessels with new or shivered carbon
  • Leveling of the carbon bed
 
 
 
Carbon extraction
  
Packaging of old carbon in big bags
 
 

 

 
 
 

Shivering of old carbon 

All these services are offered in all continental Europe and all the jobs are performed according to German norm DIN 3188 and specifications BG: ZH1/77 et ZH1/78 with full respect of any Safety regulation. 

The jobs are carried out with proprietary tools, equipment and machinery and the Customer has not to provide fans, air compressor, vacuum units, filters, cranes, fork lifts or any other kind of tools that is required by the job and in full respect of the Environment. 

We are ready to answer to any requirement you should have, ready to process any question you will submit us, and offer you our solution to your problem. If you are interested, we can send, on demand, full documentation on the activated carbon, full information on the offered services related to the activated carbon plants and send you further literature on the vegetal activated carbon.
