What is coal and how is it used?

What is coal?

Coal is the name of a black and energetic mineral that originates from the remains of trees, shrubs and other living plants of the year. The appearance and appearance of these plants is a sedimentary rock in periods where the air and the air is mild and wet earth of coal. Although some coal mines were formed 400 million years ago and during the Silurian period, the Silvery man appeared in the third period of the first period of geology, which is the emergence of drought plants, but a large part of these reserves is approximately 250 Millions of years ago, during and after the carboniferous period (carboniferous period: carbon dioxide or carbonaceous period is said to be part of the first geological period, beginning at about 345 million years ago). Subsequently, conditions for the growth of ferns of enormous tropical grains and grassless trees were provided in large swamps. These plants fall off into the marshes after drying and disappearing into the marshes, resulting in accelerated anaerobic digestion due to excretion of auxin. The vegetation has been transformed into a slime-like substance, called Pete. The pates were depending on the degree of corruption, some were black and spoiled, and some were black and tight. The sea went on such a deposition, and the mineral deposits sank to them. Pitt is under a dry and hard pressure and is converted to pit coal (lnit or lignite, also known as carbonizing coal). The greater pressure and the passage of time resulted in the production of pitch coal, which every 6 meters thickened the initial sedimentation of the early plants to 0.3 m of coal. The greater pressure caused by the earth’s land was a huge mountain range, the hardest and most profitable type of coal, Anthracite. The quality of coal is determined from the ratio of the amount of carbon stabilized to the moisture content and volatile matter (the material converted to heat to gas).

coal mining plus

Although long-distance coal has only been used as the first source of energy, today it has been a huge waste of time. The most important use of coal is coal for the production of energy and coking coal for steelmaking. In 2001, about 70% of the steel produced was coal It is still, as in the past, the most important importance of coal in the world for the supply of energy and power plants. Now (2001), 38% of the world’s electricity is generated by coal mines and about 23% of the energy needed for human production is from coal. This share is in countries Different varies from one another (Table 1) Until 1999, coal still became the most important source of energy, with 51 percent of its electricity supplied from coal.

Application of Coal in the World

Even this share in the energy supply of some parts of the country is 90 percent. For example, about 90 percent of the Ohio state’s energy is supplied from coal. In 1997, Japan accounted for 17 percent of Japan’s primary source of energy, while more coal was used to produce Electricity has been in operation at the facility (Tables 2 and 3), so that about 19% of the total electricity generated by that country was coal. Similarly, in 1994, 36 per cent of Asia’s coal-fired power plants were in coal-fired power plants. About 80 per cent of the countries in China were about 75 per cent in India.

The thermal value of one kilogram of good thermal coal is 8000-7000 kcal. Thermal value of one liter of petroleum is about 10,000 kilocalories. That is why coal is still an important fuel source of the world. Today, even from coal-fired lignite types of thermal value They are smaller, also used as fuel for cement factories, for example in the former Yugoslavia.

Nowadays, coal coke is used as a reducing agent for metals such as zinc and aluminum. For example, zinc metal coke is used as a reducing agent in the distillation process. In this method, thermal cracking generates zinc as gas and carbon monoxide gas The gases are then passed through various condensers. In this case, metallic vapors are collected in the melt. In Australia, too, aluminum is widely used in coal mining, which accounts for about 10% of the world’s aluminum production.

what is Talc minerals?

The talc consists of magnesium silicate hydrate, the chemical formula is Mg3Si4O10 (OH) 2. Mousse is the softest mineral in a tough table and it can scratch it with a nail on it. Slabs are flexible, but not elastic, the conductor is not good for heat, and when we touch it, we feel that it is greasy. Luminescence is often white to green, yellow, cream, brown, green, and blue. This mineral does not dissolve in water, but it dissolves in acidic minerals and does not melt in the flame. The same mineral is pyrophyllite, which is detectable by Mg (pink). The flower head, which itself is a rock, is completely composed of loose.

Chemical properties of talc are:
Alkaline PH (9.5-9.9), which in spite of it acts neutrally in many chemical reactants, but dissolves in hot phosphoric acid. Its cation exchange capacity for talcum powder with a surface area of ​​17.6 square meters per gram is very low and about 2.4 milliquivalents per 100 grams. The intrinsic properties of sheet or sheet talc in many industrial applications is one of its most important characteristics.
In fact, the most important chemical properties of talc is the lack of chemical effect. This property has also shown a high resistance to chemical weathering in nature. The other chemical properties of talc are highly resistant to most acids.
All of the above properties make talc in various industries such as ceramics, papermaking, dyeing, plastics, rubber, cosmetics, sanitary and pharmaceutical products, agricultural and livestock products, insecticides, waxes, coatings of roof covering materials, Textile, fabrication, preparation of dynamites and chemical industry of explosives, seals and putty.

In Chinese and ceramic industries, tiles and insulators

The presence of talc in ceramic creates resistance in products, and since talc prevents tiles from forming cracks and tiles as time goes by, its use in the industry is more welcomed. Other talents in the ceramic and tile industry are the high heat or acid resistance, and the smallest volume variation in the wide range of heat and its greater clarity. Talc is used in glazes where silica and magnesium need to be found. In low grade, about 4% of talc is used as a melting aid and in high grade as a refractory and an agent for thermal shock resistance.

Talc is generally consumed as melting aid. It also consumes from 5 to 15% in colored slurries. Relatively pure tin is used with a lower percentage in the mixture of tile glazes. Talc consumption in ceramic requires physical and chemical properties of uniformity and should be free of manganese and iron, and for high-frequency insulators, more than 5% CaO and 1.5% iron oxide and 4% Al2O3 are not allowed.

What is mineral barite? What does it use in drilling oils?

What is mineral barite?

Barite is pronounced in English (Baryte), and this name is derived from the Greek language, derived from the word Baros, meaning “heavy” or “weighty.” Which represents a high level of barite. The barite-containing barium sulfate (BaSO4) mineral content. It is usually colorless or dyed, but there are red-brown-yellow-purple colors. The color of the barite depends on its impurities at the time of its crystallization. Hardness of barite is between 3 and 4.30. The high density of barite makes it worthwhile. Barite is chemically neutral and insoluble.

This mineral is one of the main sources of barium in the chemical industry. The highest intake of barium is in the form of lithopone, which is a monolithic composition of barite and zinc sulfur. Lithopone is used as coloring agent in the coloring industry and in the textile industry. Sulfur Barium is used as a filler in the clothing and cosmetics industry as well as in white pigments. Barite in the rubber, paper, leather, glazing (smooth and transparent), ceramics (as glazes), insecticides, refractories, brake pads and atomic reactors (due to absorption of rays Gamma by barium). In the ceramic industry, the barium carbonate compound is used in the refining and producing industries of molasses and barium nitrate to produce bullets and explosive detonators. A mixture of rubber, asphalt and 10% with rite is used to cover the surface of car parks, roads and airports.

The amount of barite production in the world and Iran

Its production in 1996 was around 4.5 million tons. England, Romania, Czech, Slovakia, Morocco, Algeria, Germany, Russia, Mexico, Canada and the United States are the major countries producing barite in the world. There are several mines of barite in Iran. The main Iranian barite mines are shown in the table below. There are about 20 active barite mines in Iran, which annually produces and supplies around 160,000 baritones of barite to domestic and foreign markets.

What does it use in drilling oils?

In deep drilling for oil and gas in a rotary manner, and in areas where gas or liquid pressure is low, for catheterization, a heavy product is required that, in turn, controls the flow of materials and prevents it from being pressurized. Due to the proper conditions of barite in this case it is used. In this case, the barite powder is added to the usual solution of water and clay. Due to the beneficial properties of this mixture, such a heavy chemical composition, cleanliness and a relatively inexpensive price is neutral.

Generally, 3.6 times the annual production of barite is absorbed and consumed in this area. Barite is a vital minerals in the oil and gas drilling industry. According to the 1980s, about 90 percent of the barite was consumed in drilling mud. Barite is used for drilling mud due to its high specific gravity, the simplicity of use during work, chemical neutrality, and fineness and suitability for price. The amount of barite consumed per km of drilling was reported at about 429 tonnes.

What is gilsonite?

Gilsonite is a natural resin hydrocarbon. This bitumen is like a thick bitumen oil known as bitumen and bitumen and mineral bitumen. Gilsonite is soluble in aromatic petroleum solvents and fatty solvents such as petroleum bitumen. Because of the extreme compatibility with petroleum products, they are often used to loosen and tighten them. Gilsonite is a massive black and glowing material similar to glass minerals. This material is fragile and very easily converted into dark brown powder.
Gilsonite is found in vertical veins below the surface of the soil. The width of these veins is between 2 and 6 feet, sometimes reaching 28 feet. These veins are usually parallel and drawn from northwest to south east. The length of these veins may be very large and have a depth of 1500 miles.

Advantages of Gilsonite in pavement coverings

1.  Increase resistance to deformation and road economical benefits and reduce costs
2.  Increased resistance to shear forces and fatigue strength
3.  Increased durability of the way, Compensation for poor mix design, Compensation for degradation
Gilsonite is a natural substance. Carbon containing carbon and fugitive gases such as methane. With special properties defined in the holes and very similar to the synthetic resins obtained in the refinery.
Chemically, Gilsonite is the same bitumen refiner, but without evaporation of gas and coal, such as coal, the increase in gases in Gilsonite makes it more like a bitumen refiner.
Bitumen is usually 160 to 220 degrees Celsius. The temperature is steadily rising to 350 degrees Celsius. At this temperature, all volatile gases are released. The amount of residual material is called pure carbon. The temperature reaches 800 ° C with the same process for decomposition of carbon compounds. The residual material is called ash, which is a combination of iron silicon, calcium carbonate, sulfur oxide, magnesium oxide, aluminum oxide and silicon oxide.
The unique hydrocarbons found in plaster are distinguished from bitumen. Gilsonite can be used as an additive in hot and asphalt materials or as a combination of herbal food and easily bonded to bitumen.
Gilsonite is often used by manufacturers of insulators, insulators, pavements, road engineers and contractors to achieve high performance and affordable prices. Mineral bitumen is known as the asphalt optimizer. It is also a unique material for resistant to asphalt-resistant surfaces.
Advanced experiments on MD solubility can be performed and measure different properties. Some of these experiments included FTIR, NMR, TGA H / C RATIO, RCAP, HPLC, VPO,
Bitumen is an extruder material widely used in asphalt and bitumen factories, as well as insulating and insulating industries. Unfortunately, due to the lack of adequate knowledge about abnormalities and inadequate access to laboratory facilities, these materials are commonly used in factories, and the directors of these industries are often exposed to these materials continuously. The solution is that asphalt, asphalt and insulation as well as other related industries, by increasing the technical knowledge and equipping of standard laboratories, are able to carry out reliable analysis of their bitumen materials provided by them, will also be able to best combine these Have the matter in your processes.
Technical knowledge has been upgraded and modern laboratories of the company may help industrialists. Ensuring the purchase of the same material that your production line really needs is value added and value added that smart managers and industry experts know about. Also, the use of bitumen in the processes of botanical factories and the optimal method of using salt in the Yoghurt production lines, which gives ultimate adhesion and ultimate attraction, is a technical knowledge and experience of many of our years.
