Saturated vapour pressure is considered the most important property of LNG; it is the absolute pressure at which a liquid is in equilibrium with its own vapours at a given temperature. Some gas species within the raw natural gas will condense to a liquid state if the temperature is reduced to below the hydrocarbon dew-point temperature at a definitive pressure. The higher pressure needs to be compatible with the cooling media used for qH. Water boils at 18°C under 15 millimeters of mercury. Natural Gas Liquids (NGL) Associated gas found in combination with crude oil comprises mainly methane and NGL. 109 0 obj <>stream The boiling point is defined as the temperature at which a liquid's saturated vapour pressure equals the atmospheric pressure surrounding it.

Liquefied natural gas (LNG) is a fuel alternative that utilizes natural gas in its liquid form. Recent practice has been to liquefy the gas that is normally flared in oil fields in remote areas, but liquefaction can also be made from landfill gas when purified. The boiling point of a substance is the temperature at which it can change state from a liquid to a gas throughout the bulk of the liquid. %���� In 1959 a shipload of LNG went from Louisiana to Britain and restarted the LNG industry. It is now a major worldwide energy industry and the topic of this work. Compressed Natural Gas carrier ships CNG carrier are designed for transportation of natural gas under high pressure.

Propane, with a boiling point of -44 ºF (-42 ºC), can be stored as a liquid under moderate pres-sure, although it is a gas at atmospheric pressure. <> LNG is a colourless, odourless liquid kept at a temperature slightly below the boiling point at a relative pre-pressure of 60 mbar to 100 mbar [4]. Natural gas may be converted to a liquid state by pressure and severe cooling for transportation purposes, and then returned to a gaseous state to be used as fuel.

For example, the European Union uses the boiling point, rather than its volatility in its definition of VOCs. The principal reason for liquefying natural gas is a 600-fold reduction in volume that occurs with the vapor-to-liquid phase change. 3.18. . The "boiling point" is the temperature at which a liquid boils or at which it converts rapidly from a liquid to a vapour or gas at atmospheric pressure. boiling point at atmospheric pressure (approximately - 160 degree C).

The purification and cooling transform the gas into a liquid, which is then cooled below its boiling point to remove extra compounds in the fuel. Perhaps the most important and widely-used fluids are liquefied natural gas or LNG (bp = boiling point about 120 K), liquid oxygen (bp 90.2 K) and liquid nitrogen (bp 77.3 K).. If there is any accidental spill or loss of containment on ground surface or water, flammable vapour (predominately methane) will be produced due to the heat transfer to the liquid pool. Methane is used as feed stock to chemical industry and is the main constituent of the fuel natural gas. 62 0 obj <> endobj point and the critical point, with a particular interest in the normal boiling point, i.e. VOCs are sometimes categorized by the ease they will be emitted. boiling point of LNG at atmospheric pressure is -258.7 °F, which requires piping and containment systems to be insulated to protect personnel and maintain the temperature of the fluid. LNG, which is predominantly artificially liquefied methane , is not to be confused with NGLs , natural gas liquids , which are heavier fractions that occur naturally as liquids. Boiling Point. The rationale for liquefying natural gas is that at atmospheric pressure, the liquid density at normal boiling point of methane is approximately 610 times greater than that of the gas at ambient . These ships are usually dedicated vessels, but some smaller examples may also carry basic LPG cargoes. The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. Density of 458-463 Kg/m 3 (depending on composition). It is a colourless, clear fluid with no odour. Please read AddThis Privacy for more information. LNG is usually stored at atmospheric pressure and at its atmospheric pressure boiling temperature of approximately -162oC. LNG is an acronym for Liquefied Natural Gas, which is basically constituted of methane (C1) supplemented by ethane (C2), propane (C3), and butane (C4).
