Methanol

Methanol is a liquid that is predominantly produced from natural gas and is utilized in a variety of industrial and energy related applications. Methanol (methyl alcohol) was originally produced by heating wood chips in the absence of air. Some of the carbohydrates in the wood are broken down to form methanol, and the methanol vapor is then condensed.

What’s Methanol?

Methanol, also known as methyl alcohol among others, is a chemical with the formula CH3OH (a methyl group linked to a hydroxyl group, often abbreviated MeOH). Methanol acquired the name wood alcohol because it was once produced chiefly by the destructive distillation of wood. Today, methanol is mainly produced industrially by hydrogenation of carbon monoxide.

Condensation of methanol to produce hydrocarbons and even aromatic systems is the basis of several technologies related to gas to liquids. These include methanol-to-hydrocarbons (MTH), methanol to gasoline (MTG), and methanol to olefins (MTO), and methanol to propylene (MTP). These conversions are catalyzed by zeolites as heterogeneous catalysts.

Properties of Methanol

Methanol is a colorless liquid that boils at 64.96 °C, and solidifies at −93.9 °C. Methanol forms explosive mixtures with air and burns with a nonluminous flame. Methanol is completely miscible in water. Methanol has an odour that is similar to ethyl alcohol, the intoxicant of alcoholic beverages, but Methanol is a dangerous poison; many cases of blindness or death have been caused by drinking mixtures containing it.

Methanol is a clear, colorless liquid that is water soluble. Methanol occurs naturally in the environment and as an organic molecule, is a building block of life. Methanol is also a naturally occurring chemical in fruits and vegetables and all humans carry background levels of methanol in their bodies as a result of their diet. Methanol has even been found on newborn stars in space.

The chemical derivatives produced from methanol

Formaldehyde: Formaldehyde is a primary derivative of methanol, Formaldehyde derivatives, such as urethane (for urethane foam products) and plastics, used in home construction and furniture.

Acetic acid: a derivative of methanol, Acetic acid is used to produce terephthalic acid (PTA) and polyethylene terephthalate (PET). PTA is used to make polyester fiber for carpeting and textiles.

(PET) plastic is used to package beverages and household products. Acetic acid is used to manufacture water-based paints and adhesives and is a welcome replacement for solvent-based products.

Methyl tertiary-butyl ether: Methyl tertiary-butyl ether (MTBE) is a clean-burning gasoline component manufactured from methanol.  The use of MTBE as an oxygenate to reduce vehicle emissions.

Dimethyl ether: Dimethyl ether (DME) is a clean-burning fuel used primarily for household cooking and heating in China as a substitute for liquefied petroleum gas (LPG).

Common Methanol Applications

Methanol is an essential ingredient used to produce hundreds of everyday industrial and consumer items. Methanol is also a clean-burning, cost-competitive alternative fuel.

‚ÄčMethanol is the simplest alcohol compound, comprised of one carbon atom, one oxygen atom and four hydrogen atoms (CH3OH) .Methanol is a versatile chemical intermediate used in the manufacture of a broad range of downstream applications which we use in our daily lives, including fuel additives, solvents, polymers and specialized compounds. Methanol is a key chemical ingredient in countless industries. Methanol is a basic for the production of other chemical products such as Plastics, Paints and Man-Made Fibers, use in the production of Gasoline Fuel additives.   Below are a few products and manufacturing processes that use methanol:

Methanol usage used to make

Methanol is a polar liquid at room temperature. It is used as antifreeze, solvent, fuel, and as a denaturant for ethanol. The chemical is also used to produce biodiesel.

Methanol is used as raw material in many industries, environment friendly fuel and also in a lot of other industries, Methanol used to make:

 Chemicals

 Produce formaldehyde, formaldehyde production for use in MDF and plywood industry

 Acetic acid, Acetic acid production for use in VAM and cellulose acetate in textile industry.

Wood adhesives, Types of industrial adhesives, lumber industry, laminates

 Resins

Plastic products

Paint

Solvents for the textile industry, antifreeze

Polyester fibers for clothing and carpeting

Producing ethylene and propylene as raw material of petrochemical companies.

Methanol is used as a direct fuel for automobile engines, a fuel blended with gasoline, and an octane booster in reformulated gasoline.

The methanol in the environment

• Methanol occurs naturally in the environment and as an organic molecule, is a building block of life.

• Methanol evaporates when exposed to air. When released into the air, it is readily biodegradable and will break down into other relatively non-hazardous chemicals.

• Methanol dissolves quickly and completely when mixed with water. When released into water, it is diluted and disperse.

• Methanol does not bind well to soil and will evaporate from soil when exposed to air.

• Methanol does not accumulate in the cells of plants and animals.

Health effect in methanol

Exposure to methanol may cause irritation of the eyes, nose, mouth and throat. Methanol can lead to liver damage, cause headaches, cardiac depression, nausea, vomiting, blurred vision, optic nerve damage, dizziness and a feeling of intoxication.

Repeated contact can dry the skin, resulting in the skin cracking, peeling and itching. Exposure to high concentrations of methanol can cause coma or death, temporary or permanent blindness.

Environmental effects methanol

Methanol may affect animals, birds and fish. Exposure can also cause low growth rate in plants. Long term methanol exposure can affect the fertility of biota. Methanol does not concentrate in fish. Methanol eventually evaporates when exposed to air and dissolves completely when mixed with water.

Fast shipping

Until 1990 Iran had no methanol production unit and it had to ship in the necessary methanol. Following the 1979 Islamic Revolution and during the 1980-1988 imposed war, the NPC envisioned designing a methanol unit to produce 84,000 tons of methanol a year. The would-be methanol facility was decided to be built near the Shiraz Petrochemical Plant which is located near methanol consumption units. The facility was launched in 1990, followed by the Kharg, Fanavaran and Zagros methanol plants.

The US is currently importing over 85% of its methanol needs, while European nations depend on imports from the Middle East and North Africa for more than 60% of their methanol needs.
