Sulfur is a chemical nonmetallic element.

At room temperature, it is normally bright yellow, light solid with an unpleasant smell. When reacting with hydrogen it smells like a rotten egg. It is insoluble in water.

Sulfur may be originated from minerals or gas and oil. Previously Sulphur was mainly extracted from salt domes until the late twentieth century. Today Sulphur is mainly derived as a side product of the oil and gas refining process which is mostly in form of H2S known as hydrogen sulfide.

Another major Sulphur containing impurity in petroleum are the organoSulphur compounds which may be hydrodeSulphurized and yield hydrogen sulfide. This Hydrogen sulfide undergoes the Claus Process in which hydrogen sulfide is oxidized to Sulphur oxide and then again the Sulphur oxide reacts with some other hydrogen sulfide and results in final products: Sulphur and water.

Sulfur Applications

Sulfur is widely used as raw material in numerous applications: Sulphuric Acid, Fertilizers, pharmaceuticals, Bactericide in winemaking and food preservation, and Sulphur inlay in types of furniture.

Fertilizer: Every day the fertilizers composed of Sulphur are increasing. The most important Sulphur containing fertilizer is mineral calcium sulfate.

As elemental Sulphur’s hydrophobicity does not let it be used directly by plants. Soil bacteria can convert it to derivatives that are soluble that is can then be consumed by plants. Sulfur improves the efficiency of other vital plant nutrients, especially nitrogen and phosphorus.

Biologically produced Sulphur particles are naturally hydrophilic due to a biopolymer coating, they are easier to disperse over the land in a spray of diluted slurry, which results in a faster uptake.

The botanical requirement for Sulphur equals or even exceeds the requirement for phosphorus. It is an essential nutrient for plant growth, root nodule formation of legumes, and immunity and defense systems. Sulfur deficiency has become widespread in many countries in Europe.

As atmospheric intake of Sulphur decreases continually, the deficit in the Sulphur input/output is more probable to increase unless Sulphur fertilizers are used.

Sulfur is Known and applied from thousand years ago. It has a varied range of uses so that in the past, sulfur consumption performed as an indicator that demonstrated the industrial activities of a country.

One of its main and primary applications is acid sulfuric production that is useful to produce organic chemicals, minerals, and mainly agricultural fertilizers. Also, sulfur is used to produce explosive materials, rayon, reagents, color emollients, tires, matches, phosphate fertilizers, asphalt, sulfuric concrete, nitrogen fertilizers like ammonium sulfate and etc.

Sulphuric Acid: Sulphur, as an element, is mainly applied to produce Sulphuric Acid. Sulphuric acid is a very important commodity chemical, and indeed, a nation’s Sulphuric acid production is a good indicator of its industrial strength.

World production in 2004 was about 180 million MT, with Asia 35%, North America 24%, Africa 11%, Western Europe 10%, Eastern Europe and Russia 10%, Australia and Oceania 7%, South America 7%.

The major principal application of Acid Sulphuric is extracting phosphate ores to produce fertilizers. Approximate 60% of the Sulphuric Acid market belongs to chemical fertilizers production. Other applications include the refining process of oil, wastewater processing, and extraction of minerals.

That is why only in the US in 2010, Sulphuric acid was produced more than any other inorganic industrial chemical. About 20% is used in the chemical industry for the production of detergents, synthetic resins, dyestuffs, pharmaceuticals, petroleum catalysts, insecticides, and antifreeze, as well as in various processes such as oil well acidizing, aluminum reduction, paper sizing, water treatment.

About 6% of uses are related to pigments and include paints, enamels, printing inks, coated fabrics, and paper, and the rest is dispersed into a multitude of applications such as the production of explosives, cellophane, acetate and viscose textiles, lubricants, non-ferrous metals, and batteries.

Chemical Fertilizers

The consumption growth rate of Sulphuric acid in the United States in 1985-1997 was only 2.2% which raised to 3.9% in 1997-2004. Acid Sulphuric is the key raw material in the production of Phosphoric Acid, Ammonium Sulphate fertilizers, and normal superphosphate, whereas phosphoric acid itself is the raw material in phosphate fertilizers’ production process.

Phosphoric Acid: the major process in which Sulphuric acid is required for phosphoric acid production is Wet Process.

In this process, phosphate rock is used, and more than 100 million MT are processed annually. This raw material is shown as fluorapatite, though the exact composition may vary. This is treated with 93% Sulphuric acid to produce calcium sulfate, hydrogen fluoride (HF), and phosphoric acid.

The HF is removed as hydrofluoric acid. Other phosphoric acid types which is the furnace type, do not require Sulphuric acid. In recent years due to the wet process of phosphoric acid’s massive production, this phosphoric acid is purified in another process and used instead of the furnace of phosphoric acid, either. Hence, the Sulphuric acid market is directly affected by phosphoric acid and its relative fertilizers production.

Ammonium sulfate, a key nitrogen fertilizer, is majorly produced as a byproduct from coking plants to supply the iron and steel-making plants.

Its reacting the ammonia produced in the thermal decomposition of coal with waste Sulphuric acid allows the ammonia to be crystallized out as a salt (often brown due to iron contamination) and sold into the agrochemical industries.

One other important application of Sulphuric acid is in manufacturing aluminum sulfate, also called paper maker’s alum. This can react with small amounts of soap on paper pulp fibers to give gelatinous aluminum carboxylates, which help coagulate the pulp fibers into a hard paper surface.

It is also used for making aluminum hydroxide that is used at water treatment plants to filter out impurities, as well as to improve the taste of the water. Aluminum sulfate is made by reacting bauxite with Sulphuric acid.

Sulphuric acid is also important in the manufacturing of dyestuffs solutions.

Sulfur–iodine cycle: This is a series of thermochemical processes used to yield hydrogen. It consists of three chemical reactions which net reactant is water and the net products are hydrogen and oxygen. The first step of the cycle is called the Bunsen reaction, where the Sulphur and iodine compounds are recovered to be reused, hence the process is referred to as a cycle.

The Sulphur–iodine cycle has been proposed as a way to supply hydrogen for a hydrogen-based economy.

Industrial cleaning agent: Sulphuric acid is widely used in the iron and steelmaking industry to remove oxidation, rust, and scaling from rolled sheets and billets prior to sale to the automobile and major appliances industry.

Used acid is often recycled through a spent acid regeneration (SAR) plant.

SAR plants are commonly added to metal smelting plants, oil refineries, and other industries where Sulphuric acid is consumed in bulk, since operating a SAR plant is way cheaper than the recurring costs of spent acid disposal and new acid purchase.

Catalyst: Sulphuric acid is used for various other purposes in the chemical industry. For instance, it is the usual acid catalyst for the conversion of cyclohexanone oxime to caprolactam, used for making nylon. It is used for making hydrochloric acid from salt via the Mannheim process. Much H2SO4 is used in petroleum refining, as a catalyst for the reaction of isobutane with isobutylene to give isooctane, a compound that improves the octane rating of gasoline (petrol).

Sulphuric acid is also often used as a dehydrating or oxidizing agent in industrial reactions, such as the dehydration of various sugars to form solid carbon.

Electrolyte: Acidic drain cleaners usually contain Sulphuric acid at a high concentration which turns a piece of pH paper red and chars it instantly, demonstrating both the strong acidic nature and dehydrating property.

Sulphuric acid acts as the electrolyte in lead-acid batteries (lead-acid accumulator).

An acidic drain cleaner can be used to dissolve grease, hair, and even tissue paper inside water pipes.

Domestic uses: High concentration Sulphuric acid is commonly the major ingredient of acidic drain cleaners or openers used to remove grease, hair, tissue paper, etc.

Like their alkaline types, such drain openers can dissolve fats and proteins through hydrolysis. Moreover, as concentrated Sulphuric acid has a strong dehydrating property, it can remove tissue paper via dehydration as well.

Strategic Significance of Sulphuric Acid

As further discussed, the major application of Sulphuric Acid is in the production of phosphate fertilizers. Hence this makes the strategic significance of Sulphuric Acid.

The increasing population growth rate and limited agricultural lands increase the necessity of improving production efficiency per land unit. In order to be able to be responsible for population growth, organic fertilizers are no more applicable.

Organic fertilizers only improve the dust’s physical properties and make it ready for plant growth and it is still poor in nutrition. To improve efficiency, using chemical fertilizers is a must which necessity is completely discovered.

Sulphuric Acid is widely used in phosphate fertilizers and ammonium sulfate fertilizers and since it is not replaceable with any other materials, its significance is emphasized.

Extensive Applications of Sulphur in Various Industries

Sulfur is known and discovered thousand years ago but it was mostly overlooked. Today, a huge area of focus is on sulfur as a practical and useful chemical in different industries. Its easy accessibility has made it an important raw material in industry and agriculture and consequently, it is well-paid attention to in recent decades. High activities in sulfur trading are originated from the wide scope of sulfur consumption in four main fields including agriculture, industry, pharmaceutical, and construction. The bellow diagram is representing various sulfur applications.

  1. Agriculture:

The importance of sulfur fertilizer in agriculture has been recognized for more than a century. Sulfur is one of the 17 essential plant nutrients. Although some agronomists believe that sulfur is the fourth major plant nutrient after nitrogen, phosphorus, and potassium which are critical components of a well-fertilized crop, many consider sulfur as the second most important nutrient, placed after nitrogen.

Due to the role of sulfur fertilizer in plant development, it is applied by farmers on large scale and globally. Some of the key effects of sulfur fertilizer on plants are as follow the formation of chlorophyll, protein, amino acids, vitamins, and enzymes as well as the synthesis of oils, and improvement of crop yields. Sulfur deficiencies can cause serious plant health problems and loss of vitality. This significance caused sulfur fertilizer to be a valuable product in the agro-industry.

  1. Industry:

Sulfur application in the industry is also wide and impressive. It is used to produce sulfuric acid, rubber, sugar, detergent, pigment, paper, plastic and etc. The main and primary use of sulfur is to produce sulfuric acid which is composed of sulfur, oxygen, and hydrogen. About 85~90% of the produced sulfur in the world is applied in sulfuric acid production.  Sulfuric acid is a basic material used in the manufacturing of many final products.

  1. Pharmaceutical:

Sulfur is used in soap manufacturing. Along with the sulfur, are the ingredients used in making soap, such as mineral oil or vegetable oils, as well as lye, water, and fragrance. Most sulfur soap producers use a 10% sulfur content, although there are gentler versions with 3% content. Sulfur is also used in the production of some medicines.

  1. Construction:

Sulfur is even welcomed in the production of asphalt, concrete, floor covering, and house façade. Sulfur compounds are used in asphalt to reinforce and increase the resistance and durability of solvents of asphalt.

Sulfuric Acid, the Main Product of Sulfur

Sulfuric acid (H2SO4) as the main product of sulfur is applied widely in various industries due to its acidity, reactivity, corrosive manner, sulfur content, and water solubility.

It is a material used to produce chemical fertilizers, paper, pulp, pigment, textile, detergent, plastic, battery, and explosive subjects. Also, sulfuric acid (alternative spelling sulphuric acid) is used in mineral processing, metal refining, water refinery, oil refining, and petrochemical processing.

About half of the global production of sulfuric acid is used to manufacture phosphoric acid, which is used largely in high-grade phosphate fertilizers. You can see the uses of sulfuric acid below the figure.

Sulfuric Acid Applications

Sulfuric Acid Production

The main elements for sulfuric acid production are elemental sulfur or emission gas obtained from melting base metals and pyrite (iron sulfide). Elemental sulfur is burned or sulfide minerals are melted to produce sulfur dioxide (SO2).

This material becomes oxidized in presence of one more catalyst and creates sulfur trioxide (SO3).

Then sulfur trioxide changes to sulfuric acid by water absorption. Sulfuric acid can be made in various grades and densities. Bellow 4 stages of sulfuric acid production are mentioned:

  1. Extraction of sulfur
  2. Conversion of sulfur to sulfur dioxide
  3. Conversion of sulfur dioxide to sulfur trioxide
  4. Conversion of sulfur trioxide to sulfuric acid

Sulfuric acid producers and consumers                   

The largest chemical market is related to sulfuric acid by 6,242 million MT of production and consumption which is worth more than 20 milliard dollars.

China, the USA, India, Russia, and Morocco are the main producers of sulfuric acid in the world. The key exporters of sulfuric acid are South Korea, Japan, and Canada. America, Chile, Morocco, Australia, India are also known as great importers of sulfuric acid.

Iran high potential in sulfuric acid production

About 44 companies are producing sulfuric acid mainly for the internal market of Iran, a total capacity of 1.98 million MT.  The sulfuric acid demand in the internal market of Iran is less than 800,000 MT which is fulfilled by internal production. It should be noted that about 60% of Iran’s capacity to produce sulfuric acid is inactive.

High international demands for sulfuric acid and Iran’s great potential for sulfuric acid production made the Iranian government encourage and support Iranian producers of sulfuric acid.  Not too far the name of Iran will be found as key manufacture of sulfuric acid.

Due to the wide market of sulfuric acid, Amoot Iranian Trading Company provides sulfur as the main element for sulfuric acid production. We are ready to supply different shapes of sulfur according to the customers’ needs including granulated sulfur, lumps, prilled, and sulfur powder.
