Definitions
- This invention is framed in the field of chemical engineering applied in the petroleum industry, especially in exploration, extraction, refining, transport, storage in any area that handles both new and used fuels, to clean and handle the possible handling incidents
- the present invention relates to the manufacture of a solidifier of petroleum and vegetable oils, capable of coagulating on any surface, without interest its viscosity provided it has less density than water, adsorbs gases and vapors generated in the spills, providing protection to the environment environment and safety for relief agencies or specialized groups that attend emergencies; obtained from fibrous plant material from urban solid waste such as: vegetables, used textiles, printed paper, dry inks and soot or carbon black, graphite from discarded batteries, using state-of-the-art technique where materials are used to nano scale
- Hydrocarbon absorbents and adsorbents are composed of a wide range of organic, inorganic and synthetic products designed to remove hydrocarbons from soil and water. Its composition and configuration depend on the material used.
- Micromechanical Exfoliation It is currently the most effective method to produce individual sheets of high quality graphene. This method consists of making a stamping on Si02 support, with highly oriented pyrolytic graphite plates (HOPG). Subsequently, successive detaches are carried out by careful pressure or rubbing by dividing graphene sheets, individual or double, from the stamped graphite, which leads to thicknesses not greater than 3 nm. The low density obtained by this procedure, only a few single or double sheets per substrate area, combined with the lack of precision when positioning these sheets in a controlled manner, limit the implementation of graphene in current devices.
- HOPG highly oriented pyrolytic graphite plates
- Recent work done with ultrasound at low power on the interleaved graphite, with ternary potassium salts, K (THF) X C24 (x 1-3), obtaining negatively charged graphene sheet solutions.
- One technique with the possibility of mass production of graphene is the direct epitaxial growth of graphene on an insulating substrate. It consists of heating silicon carbide solids, to produce a partial graffiti of the upper sheet. However, this technique is hindered by the control of the number of sheets produced.
- Another strategy is focused on generating graphene oxide (GO) sheets, which have no tendency to aggregate and can be deposited as individual sheets on the surface.
- the GO is prepared using the Hummers method which consists of the strong oxidation of graphite.
- Doped graphene is a technique performed during the obtaining of carbon nano structures where manometric particles of some other compatible element can be added for the desired modification of their properties.
- Electrostatic attraction is the property of the matter responsible for electrostatic phenomena, whose effects appear in the form of attractions and repulsions among the bodies that possess it.
- static electricity refers to the accumulation of excess electrical charge (positive or negative) in a conductor or insulator.
- the effects of static electricity are familiar to most people because they can see, notice and even feel the sparks of the discharges that occur when the excess charge of the charged object is placed near a good electrical conductor (such as a conductor connected to a ground) or other object with an excess load, but with the opposite polarity.
- Induced charge occurs when a charged object repels or attracts electrons from the surface of a second object. This creates a region in the second object that is with a greater positive charge, creating an attractive force between the objects. For example, when a balloon is rubbed, the balloon will remain attached to the wall due to the attractive force exerted by two surfaces with opposite charges (the wall surface gains an induced electrical charge because the free electrons from the wall surface are repelled by the electrons that the balloon has gained by rubbing; thus a positively charged surface on the wall is created by electrostatic induction, which will attract the negative surface of the globe).
- Friction charge is transferred to the large number of electrons because friction increases the contact of one material with the other.
- the innermost electrons of an atom are strongly bound to the nucleus, of opposite charge, but the outermost of many atoms are very weakly bound and can be easily removed.
- the force that holds the outer electrons in the atom varies from one substance to another. For example, electrons are retained more strongly in the resin than in wool, and if a resin cake is rubbed with a very dry wool fabric, the electrons in the wool are transferred to the resin. Therefore, the Resin cake is left with an excess of electrons and is negatively charged. In turn, the wool fabric is left with an electron deficiency and acquires a positive charge.
- Electron-deficient atoms are ions, positive ions because, by losing electrons (which have a negative charge), their net charge is positive.
- Induction load a body can be loaded by a simple procedure that begins with the approach to it of a rod of insulated material, loaded.
- a rod of insulated material loaded.
- a non-charged conductive sphere suspended from an insulating wire.
- the conduction electrons that are on the surface of the sphere migrate to the far side of it; as a result, the far side of the sphere is negatively charged and the near one is positively charged.
- the sphere oscillates approaching the rod, because the force of attraction between the near side of the rod and the rod itself is greater than that of repulsion between the far side and the rod. We see that it has a net electric force, even if the net charge in the spheres as a whole is zero.
- Induction load is not restricted to conductors, but may occur in all materials.
- Cohesion / adhesion refers to attraction of a material to the material itself, thus opposing spreading on a solid surface, while adhesion refers to the attraction of one material to another
- Surface area A satisfactory adsorbent material must have a high relationship between surface area and volume, including available internal and external surfaces
- Buoyancy must present and maintain high buoyancy and remain afloat even when saturated with hydrocarbons and water.
- hydrocarbons begin to undergo weathering processes and their physical and chemical characteristics change over time.
- the processes of spreading, evaporation, dispersion and emulsification are important in the early stages of the spill, while photo oxidation, sedimentation and biodegradation are long-term processes that determine the final destination of hydrocarbons.
- the speed at which these processes occur depends on the climatic, meteorological conditions and characteristics of hydrocarbons such as specific gravity, volatility, viscosity and pour point.
- Evaporation and dispersion contribute to the removal of hydrocarbons from the sea surface, while emulsification causes their persistence and an increase in the volume of contaminant.
- Solidification is a physical process that consists of changing the state of matter from liquid to solid.
- Curdling is to bind a liquid so that it becomes solid or pasty; It is also coagulate, condense, solidify, freeze, harden.
- Adsorbent It is said of a body or a substance that adsorbs (attracts and retains particles from another body). It is also said of a substance, usually solid and porous, that has great capacity to retain on its surface another component present in liquid or gaseous streams.
- Catalyst any substance that modifies the speed of a chemical reaction.
- An important feature is that the catalyst mass is not modified during the chemical reaction, which differentiates it from a reagent, whose mass decreases throughout the reaction.
- Electrostatic attraction The electric charge is the property of the matter responsible for the phenomena whose effects appear in the form of attractions and repulsions among the bodies that hold it.
- Nanotechnology it is the study, design, creation, synthesis, manipulation and application of materials, devices and functional systems through the control of matter on a nano scale, and the exploitation of phenomena and properties of matter on a nano scale.
- Graphene It is a substance formed by pure carbon, with atoms arranged in a regular hexagonal pattern, similar to graphite, but on a sheet of an atom thick.
