What is the technology of this new patent ?
is based on the use of an original formulation, without
oxidant, which acts on the pollutant by transforming
it into bio-available organic compound. This formulation
is based on a well known molecule used in chemistry
since the 19th century for the synthesis of various
specialties. The use of this molecule in the areas we
are interested in is the key to the process which represents
a very important advance in technical and economic terms.
P.T.C. system is a newly patented technology for the
purification of gaseous, liquid or vesicular aerosols
containing pollutants harmful to health and the environment
or simply malodorous.
pollutants are are Volatile Inorganic Compounds (CIV)
COS, NOx, halogenohydric acids, H2S, SO2, SOCl2,
pollutants are Functional Volatile Organic Compounds
amine, amide, nitrile, aldéhyde, cétone, ester,
carboxylic acid, alcool, thiol, disulfide, thioester,
halogenated organic compounds, phosgene and hydrocyanic
innovative "One-pot" process consists in capturing gaseous
pollutants in a physicochemical treatment whose liquid
effluents are subsequently digested by the aerobic bio-purification
process in the treatment plant.
process of absorption (capture) and organic chemical
modification of Functional Volatile Compounds
(organic and inorganic).
This operation is carried out in a single operation
on a collection installation by physicochemical washing..
final destruction of capture products after the simultaneous
chemical uptake and modification process
This ultimate operation (B) is carried out in a biological
treatment plant. The organic compounds present and formed
During the condensation reaction are digested by the
process of natural aerobic bio-purification of the purification
originality of the process resides firstly in the choice
of the reagent which combines with the pollutants to
be treated and secondly in the final natural destruction
in the wastewater treatment plant, which does not generate
any new gaseous pollution.
purification system is unique in its design and applications.
It makes it possible to distinguish itself from the
competition and to improve the productivity of the collection
/ treatment installations, as much as its economic
balance sheet is advantageous.
new patent takes up the existing patent of the
DAVID process (Process for the purification of gaseous
or liquid effluents containing sulfur derivatives) for
which it constitutes an improvement.
