METHANOL
Product introduction:
Methanol is a chemical compound known as a polycarbonate alcohol with the formula CH₃OH. This colorless substance with specific smell and high volatility is soluble in water and is used in industry as an active energy source, powerful solvent, and raw material for the production of chemical products.
Methanol production process:
The general process of methanol production generally includes the following steps:
- Synthesis gas production: This stage involves the production of a mixture of hydrogen (H2) and carbon dioxide (CO), which is commonly known as synthesis gas. This mixture is in the form of flue gases.
- Synthesis gas purification: Synthesis gas produced may contain impurities such as sulfur, silica and other pollutants. These gases must be purified to prevent damage to the catalysts.
- Conversion of synthesis gas to methanol: In the presence of a catalyst, synthesis gas enters a reactor where, under certain pressure and temperature conditions, chemical reactions convert synthesis gas to methanol.
- Methanol separation: The product from the reactor is a mixture of methanol, water and other components. Separation of methanol from this mixture is mainly achieved through distillation and absorption processes.
- Refinement and purification: The obtained methanol needs to be refined and purified to reach the desired level of purity. These processes include removing water, removing impurities and adding necessary additives.
- Production of methanol on an industrial scale: in this stage, the produced methanol is packaged and distributed in bulk in industrial production units.
Properties of methanol:
Methanol is a type of alcohol and its properties include physical and chemical properties. Below are some of the properties of methanol:
1) Boiling point: The boiling point of methanol is about 64.7 degrees Celsius, indicating a relatively low boiling point.
2) Freezing point: Methanol freezes at about -97 degrees Celsius.
3) Density:The density of methanol in standard conditions is about 0.791 grams per cubic centimeter.
4) Color and smell: Methanol is colorless and has an alcoholic odor. These properties distinguish this alcohol from other substances that may be used in some applications.
5) Solvent properties: Methanol is a strong solvent and can be used as a solvent in chemical processes and various industries.
6) Fueling: Methanol can be used as a renewable fuel for domestic engines and internal combustion engines.
7) Applications: Methanol is used as a raw material or solvent in chemical industry, plastic production, paint, resin, pharmaceutical, and other industries.
8) Poison: Methanol alone is toxic and its consumption can be harmful to health. Therefore, the use of methanol should be done with caution and with the necessary safety precautions.
Standards and certificates:
For industrial methanol, it is important to use standards and certificates to guarantee the quality and safety of this chemical. In this context, standards and certifications may differ depending on the type of industry and methanol consumption. Some of the common industrial methanol standards and certifications are:
ASTM D1152 – Standard Specification for Methanol (Methyl Alcohol):
The ASTM D1152 standard deals with the physical and chemical characteristics of methanol and is considered a reliable standard for use in various industries.
ISO 15422 – Methanol Specification:
The ISO 15422 standard also deals with the technical specifications of methanol for industrial use and provides quality assurance of this product within certain limits.
GHS (Integrated System of Warnings):
It is important to use the system of labeling warnings to inform about the potential hazards of methanol and safety in the management of chemicals.
Environmental and safety certificates:
Industrial methanol products may require environmental and safety certifications and standards, for example ISO 14001 or OHSAS 18001 certifications.
International certificates:
Some international certifications may also be considered for industrial methanol, such as European Certification (CE) or ISO international certifications.
