PRIOR ART

• • There are many common fire-retardant materials that are generally used in fire extinguishing, for example, water, FOAM, dry chemicals, dry powder, carbon dioxide, and halons. However, these materials do not prevent the evaporation and explosion of crude oil or its derivatives, as they only resist and extinguish fires.
  • There is also found in the invention of US20150151630A1, dated Mar. 12, 2013, titled, explosion and ballistic resistant fuel tanks utilizing molded polymer inner liners, composite fabrics and self-sealing materials.
  • There is also found in the invention of CN102344025B, dated May 8, 2010, titled, anticorrosive flame retardant explosion-proof material. The invention relates to manufacturing and filling explosion-proof fillers made, in different proportions, from a number of alloys of Iron, Copper, Magnesium, Titanium, Zinc, Chromium, Manganese, Aluminum, Silicon, Nickel and Zirconium, formed in the form of a honeycomb-like porous structure.
  • In the processes of crude oil's processing, producing and refining, crude oil is subjected to many complex methods of processing to separate it from water, impurities and salts. The most important method thereof is using hydrophobic demulsifiers, which has many problems, on of which is high cost, wasting time and evaporation of a portion of the petroleum.

PROBLEMS AND SHORTAGE IN THE PRIOR ART

• • The defect and problems in the common fire-retardant materials are that they are not prevent vaporization and explosion of petroleum and gas derivatives, but only resist and extinguish the fires, which results in huge economic and human losses as well as loss of huge quantities of petroleum and gas derivatives.
  • One of the defects and problems is the lack of safety and security when the containers of crude oil derivatives or gas are exposed to fire, handling, transportation, storage, maintenance, collision, or lightning.
  • One of the defects and problems in the invention of US20150151630A1, is that there is a difficulty in the application, in addition to the fact that the method of manufacturing the tank structure is complicated, limited in use, and expensive, as it is used in the manufacture and design of new tanks only with a non-metallic inner liner that is fuel tanks molded from Aramid fibers, polyethylene fibers, quartz fibers, ceramic fibers, polybenzoxazole fibers, boron fibers, basalt fibers, and three-dimensional additives. This design for fuel tanks is of limited use, except in some military matters, as it is designed to resist ballistic missiles.
  • One of the defects and problems in the invention of CN102344025B, is that corrosion- and flame-resistant materials containing rare and precious metals are used, which leads to difficulty in manufacture and application. In addition, it contains some elements with a high density, which occupy a large space of the inner volume of the tank.
  • One of the defects and problems is that the impossibility of performing procedures and carrying out maintenance and welding works in cisterns and tanks that are filled with petroleum and derivatives thereof, as well as when they are empty, as it may expose petroleum and derivatives thereof to self-ignition.
  • One of the defects and problems in refining crude oil is that very large quantities of chemicals are used for treating the emulsions, called hydrophobic demulsifiers, flaws thereof are:

DETAILED DESCRIPTION

The Novelty in the Invention's Subject

• • After research and study on nano-activated carbon, and nano-graphene, the following has been found:
  • 1—The nano-activated carbon has an absorption and adsorption phenomenon depends, to a great extent, on the surface area and the size of the pores. The porous structure determines the size of the particles that can be absorbed, and the surface areas determine the amount of the material that can be adsorbed, assuming that the molecular size is appropriate. The specific surface area ranges from 300-2500 m 2/g. The amount of the substance absorbed by the activated carbon is surprisingly large, as it often ranges from a quarter to its entire weight of vapors and gases. In addition, nano-activated carbon is widely used to control vapors and gases. Accordingly, it was added to the main aluminum alloy of the smart anti-explosive material, because of its unique properties in the absorption and adsorption of gases and vapors.
  • 2—Nano-graphene substance is characterized by unique and superior chemical and physical properties of absorption and adsorption, large surface area, and reasonable price. Accordingly, it is added to the main aluminum alloy of the smart anti-explosive material.
  • 3—The super absorbent polymer (Sodium polyacrylate) absorbs 250-300 times its volume of water (according to the theories of hydraulics and fluids, the evaporation degree of one liter of water increases 1700 times its volume when exposed to fire, which leads to an explosion of the content of crude oil). Therefore, it was used in the extraction, refining and production of crude oil for disposal of the amount of water mixed with crude oil when extracting it. Thus, sodium polyacrylate has a superior capacity to improve the properties of crude oil by 99%, as it removes water in crude oil, making it less than 0.01 to 0.02%. Thus, crude oil becomes highly efficient which is demanded in global markets. In addition to securing petroleum installations from the risks of explosion.
  • Properties thereof makes international oil companies avoid using huge quantities of expensive chemicals that help removing some quantities of water mixed with crude oil (emulsion) as well as avoid environmental pollution.

Therefore, the nano-activated carbon, or nano-graphene adding structural rigidity, flexibility in forming and application, and low density and the lowest affected elements by weather factors, shocks, vibrations, moisture and chemical reactions. And also, the super absorbent polymer (sodium polyacrylate), which absorbs as its volume from 250:300 times of water, therefore, it is considered a novel and innovative addition to the prior art, on the basis of improving the form, content and performance in preventing evaporation and explosion with high efficiency compared to the prior art, and adding many applications in many other fields. Which result in avoiding the defect in the following:

Carbon and graphene, each separately, are mixed with aluminum in specific proportions of 1.5:2%, as needed, and used in petroleum liquids and gas.

When either carbon or graphene is added to the main material, it makes it easy to form a six-dimensional mesh geometrical shape, and it causes heat distraction of 65% according to laboratory tests.

The smart anti-explosive material characterized by being easy to apply without the design, of the containers, tanks or cisterns, of crude oil derivatives or gas, being touched neither internally nor externally.

  • The laboratory and field-testing results of the National Institute of Standards showed a very good explosion-resistant behavior, and it is considered as an anti-explosive material.
  • 4—The mechanism of action results from absorbing and dissipating heat and the resulting vapor, which leads to preventing explosion and delaying ignition.
  • 5—The smart anti-explosive material suppresses the speed of movement of gas particles and thus reduces the pressure on the inner wall of the container, which is one of the factors that prevent the explosion.

The convenience of maintenance and welding work of tanks and cisterns containing petroleum and its derivatives without emptying them (full or empty) without the slightest risk, as it can be loaded, modified or removed from tanks easily and conveniently, which saves effort, money and time.

DETAILED DESCRIPTION

1—The Components of the Invented Material:—

The smart anti-explosive material consists of an Aluminum alloy of purity (99%), nano-activated carbon of ratio 2% or nano-Graphene of ratio 1.5%, high purity Silicon of ratio 2%, Magnesium of ratio 0.5%, and Chromium of ratio 0.25%.

The smart anti-explosive material is formed in the shape of a six-dimensional hollow mesh sheet, thickness thereof is from 0.25 mm to 0.50 mm.

The smart anti-explosive material is formed according to the shape of the container (cisterns and tanks) that contains petroleum, derivatives thereof or gas, wherein the inner walls of the container are lined with the smart anti-explosive material in the shape of an inner shirt the dimensions thereof are calculated according to the measurements. Also, the smart anti-explosive material is placed inside the petroleum content to be protected from explosion in the form of different geometric shapes, one of which is the cylindrical shape, the dimensions of the cylinder are 2 cm to 4 cm in length, the inner diameter is from 0.6 cm to 1 cm, and the hexagonal hole scale for the mesh sheet is from 0.6 mm to 1.5 mm. Dimensions may vary according to the nature of use and application, if necessary. (As shown in drawings, FIG. 1)

The smart anti-explosive material is placed through the nozzle of the tank, pipe or cisterns that contain petroleum materials to be protected from evaporation, explosion and ignition, without the design of the container being touched, neither the internal nor external shape of the cisterns, tanks or gas pipes.

The smart anti-explosive material occupies 2% of the internal volume of petroleum, derivatives thereof or gas.

2—the Super Absorbent Polymer (Sodium Polyacrylate) Absorbs 250 to 300 Times its Volume of Water.

Mechanism of Work

1—the Smart Anti-Explosive Material:

In order for ignition to occur, it is necessary to have an ignition source and a mixture of fuel and air (Oxygen). The explosion occurs as a result of a chemical reaction that is formed as a result of processes in which energy is absorbed, i.e., they are endothermic compounds.

This energy escalates when flammable and interacting materials (petroleum derivatives) are decomposed. If the decomposition process is accompanied by large quantities of gases that expand by heat, resulted from the decomposition, they can perform mechanical work as result of the pressure of the gas formed. If the decomposition is at a speed of more than 300 msec, then this process is called combustion, before the internal combustion by machines, and if the decomposition is faster than said rate, it is called an explosion. Petroleum derivatives are considered very highly flammable materials and ignition starters, and they are highly vulnerable to explosion when hit, heated or ignited.

It has been shown through conducting laboratory experiments that the pressure of the gas is directly proportional to its temperature at constant volume. If the temperature increases, the volume is directly proportional to the amount of heat given to the gas. In case of cooling, it is proportional to the decrease in temperature, according to the general gases law. So, the thermal energy that is given to the gas increases the speed of movement of the molecules, and it is clear that the speed of the movement of the molecules determines the degree of force that they collide with the walls of the container of the gas, and accordingly the pressure on the walls of the container increases when the temperature of the gas increases. When adding the smart anti-explosive and anti-evaporative material in its shapes and weights in the tank, for example, that contains crude oil or its derivatives (gasoline, Kerosene, diesel, gas or oil) when exposed to direct or indirect heat resulting from fire, collision, friction resulted from Maintenance practices, or welding. As well as the formation of the smart anti-explosive and anti-evaporative material in the form of geometric or cylindrical shapes or inner shirt is also efficient, when gases are generated due to exposure of the tank containing petroleum materials to direct fire conditions, the gas's molecules move randomly in straight lines, where the gas molecules can be perceived as completely flexible small balls, and the distances between molecules of the gas are relatively large and the cohesion of the gas is very weak, and then, the gases and vapors generated by the effect of heat move randomly and collide with each other and collide with the walls of the inner tank. The collision between the gas molecules and the compound of the smart anti-explosive and anti-evaporative material constitutes an elastic collision, meaning that the kinetic energy of the gas molecules is constant before and after the collision, according to the law that stating that for every action, there is an equal and opposite reaction.

It has been shown through laboratory experiments that the smart anti-explosive and anti-evaporative material is able to absorb and adsorb the resulting gases and also works at the same time to reduce the movement of the molecules of the substance that is directly proportional to the amount of heat given, according to the three laws of gases:

Boyle's Law: At constant Temperature, Pressure is inversely proportional to Volume.

Charles' Law: At constant Pressure, Volume is directly proportional to Temperature.

Gay-Lussac's law: If a gas of fixed mass and fixed volume put in sealed container, the pressure is directly proportional to the gas's absolute temperature.

• • Experiments: There are 7 laboratory and field experiments (accredited by the Fire and Explosion Department at the National Institute of standards, Ministry of Scientific Research, Arab Republic of Egypt) were conducted to review the properties of the smart anti-explosive and anti-evaporative material.

Experiment No. 7

• • Maintenance was carried out by welding two tanks (diesel and gasoline) one of which was provided with a cylindrical shape of the invented material and the other provided with an inner shirt of the invented material, and it is worth noting here that it has never occurred, and it was previously unreasonable in the field of petroleum, to conduct welding works in a tank of petroleum, or trying to change a corroded sheet, for example, without completely emptying the tank or taking it out of service and replacing the petroleum vapors with nitrogen. However, in this experiment none of these safety precautions took place due to the presence of the invented material inside the tank before launching the ejector on it. The welding work is conducted completely safe in the presence a quantity of gasoline (high evaporation) inside the tank, and this is the only time that such welds can be made in a gasoline or petroleum tank without emptying it, knowing that the welding temperature may reach about 3000 degrees Celsius—and this is impossible to occur without the presence of the invented material (the smart anti-explosive material).
