PROCESS FOR SELECTIVE REFINING OF THE DI-HYDROL POLYMER BY TEMPERATURE AND PRESSURE CONDITIONS BELOW THE CRITICAL POINT OF WATER
Description
1. Problem identification
The permanent and daily conversion of drinkable water into contaminated water is significantly greater than the existing refining capacity of industrial and natural water treatment systems to convert it back for re-use. The consequences are a daily accumulation of irreversibly polluted water and also a permanent loss of usable water.
2. Problem solution in the state of the art
The current state of available technology proposes to solve the problem
referred to above in paragraph 1 by means of a large number of technical
solutions, involving a variety of procedures and processes. These
procedures have in common their inability to totally eliminate pollutants from
the effluents, only achieving a reduction of such pollutants. The continuous
drainage of these effluents into rivers, lakes or oceans causes an
accumulation of residual pollutants and thus does not solve the problem
referred to above in paragraph 1.
The biological or chemical oxidation of organic materials can be obtained by
the use of oxidation reagents. The use of these reagents is not very
advantageous as they are costly and can themselves produce pollutant
RECORD COPY
byproducts, which, in turn, require appropriate treatment.
The aforementioned biological processes executed below the critical
temperature of water, although commonly used, are not efficient enough and
cannot achieve complete oxidation, as well as developing undesirable
byproducts. Moreover, biological agents cannot be used to oxidize organic
products that are toxic or difficult to oxidize.
The wet air oxidation process, executed at temperatures below the critical
temperature of water, which has been used to oxidize many organic
products, has not, however, been able to achieve complete oxidation and
produces byproducts that are detrimental to the oxidation process.
The various solutions for eliminating organic materials, namely, the known
techniques based on the use of water in supercritical conditions, are
generally solutions used in batch form (discontinuous process) using
temperatures above 647 K and pressures above 221x105 Pa. The negative
consequences from these high pressure and temperature conditions are the
high cost of equipment, the high cost of the process and the risk of
corrosion. Additionally, these solutions do not adapt well to the objective of
regaining reusable water.
The known hydrothermal processes, such as supercritical water oxidation,
are used to fully oxidize the organic compounds. The critical temperature
and pressure of water which are, respectively, 647 K and 220.4x105 Pa, may
substantially oxidize all of the organic matter in the reaction, releasing water,
C02, N2 and inorganic byproducts, such as metals and salts.
These processes are referred to in the following North American Patents.

range of temperatures and pressures used in the above processes are

3. Invention description and fundamentals.
The invention establishes the combination of a wet air oxidation process, at
low vacuum conditions, which takes place in the second chamber reactor,
with an infracritical oxidation at temperatures below the infracritical point of
water, which takes place in the first chamber reactor, allowing the recovery
of 75 to 80% of the total liquid mass. This process is achieved by
maintaining constant the pre-selected pattern of the di-Hydrol polymer.
The Infracritical Water Oxidation reactor allows the operator to control and
adjust the infracritical water intervals at a constant pressure achieving
spontaneous superoxidation between 328 and 368 K at constant speed and
pressure of the pre-selected polydispersion at the shear stress. The photon
beam, of a specific wavelength, projected at the moment of repulsive
electrostatic stress, after the shear stress, onto the pulverized liquid stream
containing dissolved complex organic matter, inside of the first chamber of
the reactor, provokes spontaneous and short-lived first order half-reactions.
In order to sustain the oxidation potential, a specific dose of an oxidant is
added, supplying paramagnetic oxygen, thereby maintaining the irreversible
nature of the reaction, in which the high oxidation potential has an
accentuated reducing effect on the di-Hydrol polymer.
The reactor permits the operator to adjust the cinematic control of the auto-
regeneration process of the "clusters" of di-Hydrol polymer (coherent
electrostatic superposition), at low vacuum, obtaining pre-selected
refinement of the dielectric equipotential, within varying electrical potential,
selected between 0.3 and 0.4V of oxi-redox potential.
The oxi-redox neutralization, in a oxygen saturated medium, induces an
electrical flow charge, reducing the volume density of polarization and
increasing the superficial density of the charge in the polar dielectric of the
aqueous solution, due to a combination of the oxygenation cone (enriched
by a dynamic flow of micro-bubbles) and the photon beam of a specific
wavelength, during the dispersive phase inside of the second chamber of
the reactor.
The effect of the apparent electrical neutrality, after the influence of
intermediate short-lived superoxydes, accelerates the precipitation of salts
and the separation of the colloidal structures, achieving the elimination of
over 99% of the di-Hydrol polymer contaminants.
The peripheral procedures that follow these phased reactions consist of salt
filtration, extraction of gas and foam and the cleaning or burning of gases
produced during the process.
The fundamentals of the invention are as follows:
Inside each isobaric cycle of energy preservation, under wet air oxidation
conditions, the thermal variation induces a mechanism of self-oxidation di-
Hydrol, which establishes electric equipotential nano-condensators
(clustering), with limited electric capacity to produce variables in the pattern
of tri-, di- and mono-Hydrol, consequently conditioning the dynamic
characteristics of the dimerous medium (liquid phase).
During the incremental increase of temperature, inside the isobaric cycle of
energy conservation, below the critical point of vaporization and at a
constant pressure, spontaneous variations in the quantum states occur in
the Hydrol connections of an electrostatic nature, in overlapping
compressive conditions. These conditions are fundamental for the dimerous
medium to function as a nano-condensator), by electric overcharge of the
condensator, the intensity and frequency of which expresses the relation
between the relative mass and energy flow of the polar dielectric.
The periodical state of "short circuit" sets off electronic quantum jumps,
producing spontaneous quantitative differences in the relative proportions of
the tri-, di- and mono-Hydrol patterns per mol, allowing efficient free energy
absorption and, simultaneously, establishing a tendency to apparent oxy-
redox electric neutrality.
The energetic and molecular rearrangement in the dimerous medium,
resulting from the spontaneous electronic quantum jumps, define an
infracritical interval with specific expression in the ratio between the relative
mass (in mols) and the free charge flow in the polar dielectric.
In the infracritical interval, the mechanism of self-induced water regeneration
is characterized by: re-nucleation of free polarization charges, duplication of
the characteristics of oxygen of a paramagnetic nature and recombine the
Hydrol patterns in the ratio between the internal energy and a volume mass
at a given moment.
Each isobaric of water conditions the magnitude and frequency of the
mechanism of self-induced regeneration, based on auto-oxidation of a
paramagnetic nature, which can greatly reduce the Hydrol polymer, with
capacity to increase the quantity of mols and to fix the free energy, followed
by an oxi-redox neutralization with capacity to vary the relative proportions of
the patterns.
The process of refining the di-Hydrol polymer must be induced, due to the
binary character of the infracritical interval, expressed in the dimeric matrix
of liquid, that does not allow a random variation of combinations by function,
equivalent to the most complex systems, inherent in the continuous process
of auto-regeneration. Hence, the di-Hydrol polymer remains active, due to
the limitations and induced inter-relational dynamic of the dimeric matrix, in
other words, its dependency on the character and frequency of external
stimuli.
In the continuous process of refining the di-Hydrol polymer, the
superoxidation is efficient in the elimination of dissolved organic specimens,
and the neutralization is efficient in the precipitation of dissolved inorganic
specimens at low temperature.
The invention permits the recombining of the molecular structure of water,
and simultaneously eliminating therefrom, all the contaminants that are
present and recalibrating the regeneration levels, with or without chemical
oxygen demands, according to the requirements of industrial, municipal and
domestic applications. The method applied in this invention avoids the
accumulation of contaminated water and makes it possible to decentralize
local recovery operations.
The process in this invention has the following advantages: maintaining
conditions of low risk of corrosion and incrustation in the equipment;
reducing operational costs, when compared with supercritical oxidation;
eliminating the dissolved organic matter in the water, derived from the
effluents used as raw material in the process, and eliminating biological
activity; destroying the simple and complex organic chains in gas phase,
that are then reused as an alternate fuel; refining the di-Hydrol pattern and
allowing the recovery of the total liquid mass in the range of 70 to 80 per
cent.

The present invention consists of a sequential process of oxidations,
beginning with the influx 1 of real effluent, through an effluent filter 2, with
discharge regulated by on/off valve 3; using a pump of medium pressure
with regulated valve 4, for pumping said liquid effluent through a heat
exchanger 5, in order to pre-heat said liquid effluent between 325 and 375
K; the effluent then passes, with pressure controlled between 10x105 and
15x105 Pa, to a polymerizing device 6, for polymerizing hydrolyzed
coordination complexes of the effluent, with an injection of 2 to 4% in weight
of steam between 410 to 450 K, achieved by control device 7; removing
gases and foams through a modulated valve 8. In order to regulate the flow
of extraction of the polymerizing device, there is a modulated valve 9, as
well as a medium pressure pump 10 for pumping the polydispersion
obtained in the polydispersion device, at a pressure between 30x105 and the
60x105 Pa. The pumped flow will then cross an electromagnetic field
produced by a coil device system 11, powered by an electric current in the
range of 2 to 5 V, to polarize the polydispersion. This polydispersion is
projected, with constant pressure and velocity between 70 and 100 m/s, on
a pre-heated target through an induction coil 14, producing micropolarized
polydispersion inside of the first chamber of the reactor 13. Next, a radiation
source device 12, with wavelengths between 1.6x10"7 and 3.8x10"7 m, is
used to bombard, with a beam of ionizing radiation, the micropolarized
polydispersion in the said first chamber of the reactor 13, where the
infracritical water oxidation took place. The resulting gases are conducted to
a backpressure device, with gases and foams extracted by a three-way
valve 16, controlled by adequate sensors, composed of a backpressure
regulator 15 and a modulated valve 17, controlled by adequate sensors.
The monodispersion resulting from infracritical oxidation is then subjected to
the addition of the oxidant of paramagnetic nature, whose reaction is
prepared in a rapid mixing system 21 and polarized in an electromagnetic
field produce by a electromagnetic coil 22. This polarized monodispersion is
projected at constant pressure and velocity on to the heel of the second
chamber of the reactor 24, in parallel with compressed air stripping,
obtained from a compressor 23, at a pressure between the 5x105 and the
7x105 Pa and a temperature between 283 and 288 K, with a comparative
flow between 1 to 2 % of the circulating stream. By the combined effect of
air stripping, with the micropolarized monodisperson flow in the heel of the
second chamber of the reactor 24 an oxigenation cone with micro-bubbles
and ascendant streams develop, by ultracavitation, which allow the capture
of the colloid stuctures extracted in the expansion chamber of gases, on low
vacuum, controlled by a modulated valve 32. This process takes place in
wet air oxidation conditions. Subsequently, the apparent electric
neutralization process is started, in which, in addition to the already
mentioned ascendant streams, descendant streams occur, dragging salts
by gravity, conducted through an electromagnetic field, produced by an
electromagnetic coil 34, powered by an electric current between 2 and 4 V,
which caused the inorganic particles to aggregate. Inside the oxygenation
cone, various streams are produced simultaneously, created by the
pressure differential between the internal and external surfaces of the wall of
oxigenation cone, which is being cooled by recycled water, producing
microvortices exposed to an external source of polarizing radiation 26, with
wavelengths of 4x10"7 to 2x10"2 m. The stability of neutralization is obtained
with a cooling, which results from the mixture of the recycled water streams,
supplied by valve 36, with the passage of the liquid mass as a whole
through the auxiliary cooling device 27, which is a part of a system
composed of a cooling tower 30, a water pump 31 and an on/off valve 29
controlled by adequate sensors, where the refined and filtered water is
regulated by an on/off discharge valve 25, and also controlled by adequate
sensors. The refined water, controlled by the on/off valve 37, is added to the
oxidant of paramagnetic nature in the tank 18, the resulting mixture then
feeds a dosing pump 19, controlled by modulated valve 20, to be injected
under pressure into the fast mixing device 21.
The extraction of gases and foams, regulated by modulated valves 8, 17
and 32 controlled by adequate sensors, are drawn into a collector 33 which
feeds into a cyclone with a forced extraction system by vacuum pump or
high pressure fan 39, to separate solid matter from gases, conducting solids
to a container40.
The refined water, after passing through an electromagnetic field, produced
by an electromagnetic field 34, passes through a filter 35 and is recuperated
by modulated valve 38, controlled by adequate sensors.
