Study Notes
Characteristics and Handling of Natural Gas and Liquefied Natural Gas (LNG)
- Natural gas is a petroleum-based fossil fuel that is mainly composed of methane (85%-95%) and may contain other gases such as ethane, propane, nitrogen, carbon dioxide, water, and sulfur compounds.
- Methane is the simplest hydrocarbon group and is combustible, igniting only when the mixture of methane to air is between 5.3% and 15%, respectively.
- Methane is odorless, colorless, and tasteless, but odorants like mercaptan are added to the gas stream for easy detection if accidentally released.
- LNG has a boiling point of -260°F and is mainly composed of methane, which is odorless, colorless, non-toxic, and non-corrosive.
- The vapor of LNG is flammable and can displace oxygen, which may cause asphyxiation if inhaled.
- The ratio of LNG to gas vapor is 1:640, and LNG weighs about 42% that of water at standard conditions.
- In case of a large LNG spill, all sources of ignition should be eliminated, and the area should be evacuated.
- LNG has a violent reaction with water, resulting in rapid vaporization and may resemble an explosion if under the right conditions.
- Personnel involved in LNG handling should be thoroughly familiar with its characteristics and wear proper Personal Protective Equipment (PPE) such as safety glasses, cold material grade leather gloves, long sleeve shirt or jacket, protective outer garment, and boots.
- Exposure to LNG can cause serious injury, and proper first aid procedures for cryogenic burns should be followed.
- The violent boiling of the liquid will occur if a large enough volume of LNG spilled to the ground, causing the formation of a flammable vapor cloud.
- The visible fog produced by the cold LNG vapor serves as an indication of the approximate travel of the methane vapors, but the location of the visible fog is not necessarily the entire location of the LNG vapors.
