A Comprehensive Guide to Methanol Dispensers

Methanol is an alcohol commonly used in industrial processes, automobile fuel, and even as a solvent. In this comprehensive guide, we’ll deeply dive into methanol’s use in automotive fuels, methanol fueling technology, and more.


1. What is methanol?

Methanol is a colorless liquid with a mild alcoholic odor. It is the simplest form of alcohol, consisting of one carbon atom with three hydrogen atoms and a hydroxyl group (OH). Methanol can be produced by a variety of methods, such as the retort distillation of wood or through the chemical synthesis of natural gas.

2.Properties of methanol

  • Boiling point: 64.7°C
  • Melting point: -97.6°C
  • Density: 0.7918 g/cubic centimeter
  • Solubility in water: miscible

Methanol has a lower boiling point than ethanol or water, allowing it to be used in certain applications requiring low temperatures.

3. Uses of methanol

Industrial applications: Methanol is widely used in pharmaceuticals, plastics manufacturing, chemical synthesis, and other industries.

Automotive Fuel: Methanol can be used as an alternative fuel source for vehicles, alone or mixed with gasoline.

Solvent: Methanol is commonly used as a solvent for paints, varnishes, and other coatings due to its solubility properties.

Antifreeze: Because methanol lowers the freezing point of water, it is often used in antifreeze formulations.

Biodiesel production: Biodiesel is produced by the methane-glyceride transesterification process.

Methanol filling machine

4. Methanol dispensers

A liquid volume measurement system for filling M85 and M100 methanol fuel into motor vehicles.

The materials of the parts of the filling machine that come into contact with methanol should ensure their adaptability to methanol. Carbon steel, stainless steel, nitrile rubber, neoprene rubber, silicone fluorine rubber, acetal resin, nylon, polypropylene, and polytetrafluoroethylene should be used. and other materials. Aluminum, aluminum alloy, copper, galvanized, polyurethane, and other materials should not be used.

A methanol fuel secondary filter should be equipped between the terminal outlet of the filling machine and the oil gun, or an external methanol fuel secondary filter should be equipped. The filtration accuracy of the filter must be ≤1μm.

5. Main technical parameters of the methanol dispensers

  • The maximum allowable error is ±0.30%, and its measurement repeatability should not exceed 0.10%
  • The maximum allowable error of the smallest measured value is ±0.5%, and its measurement repeatability should not exceed 0.17%
  • Noise: ≤80dB
  • Suction distance: vertical distance 6 meters, horizontal distance 50 meters
  • Oil outlet pressure: ≤0.3MPa
  • Flow rate: 5L/min ~ 50L/min
  • Ambient temperature: -25~+55°C
  • Relatively moderate: ≤95%
  • Voltage: 220V/380V 50/60Hz
  • Adaptable media: M85, M100 methanol

6. Working principle of methanol dispensers

The motor drives the oil pump to pump the fuel in the oil storage tank through the oil pipe and filter into the oil and gas separator for oil and gas separation. Under the pump pressure, the fuel is transported to the motor vehicle through the flow measurement transducer, oil sight gauge, and filling nozzle.

While methanol has many practical uses across industries, it can also pose significant health risks if not handled properly: following correct safety procedures when working with methanol is important.
