What is NGL fractionation?
NGL Fractionation Once NGLs have been removed from the natural gas stream, they must be separated into their individual products to be useful. This is accomplished through fractionation. Fractionation works based on the different boiling points of the different hydrocarbons in the NGL stream.
What is an NGL facility?
Natural gas liquids (NGL) are components of natural gas that are separated from the gas state in the form of liquids. This separation occurs in a field facility or a gas processing plant through absorption, condensation, or other methods.
Are NGL and LNG the same thing?
LNG stands for Liquefied Natural Gas or Liquid Natural Gas and, as the name implies, it is traditional natural gas, which has been cooled to the point of liquefaction. It stands alone as LNG. To recap, the NGLs are comprised of ethane, propane, normal butane, isobutane and natural gasoline.
What is NGL Recovery Unit?
Natural Gas Liquids Recovery is a process for separating ethane and heavier hydrocarbons (C2+) from natural gas. Air Liquide Engineering & Construction delivers high recovery and high efficiency Natural Gas Liquids (NGL) processes, while optimizing capital and operating costs for customers.
How does NGL fractionation work?
NGLs are fractionated by heating the mixed NGL stream and processing them through a series of distillation towers. Fractionation takes advantage of the differing boiling points of the various NGL components. As the NGL stream is heated, the lightest (lowest boiling point) NGL component boils off first and separates.
What is Y-grade used for?
Magellan Pipeline terminology for No. 1 fuel oil. The feedstocks that are sent to a fractionator in order to extract gas liquids.
Is hexane an NGL?
Natural gas liquids include propane, butane, pentane, hexane and heptane, but not methane and ethane, since these hydrocarbons need refrigeration to be liquefied. The term is commonly abbreviated as NGL.
What are NGL used for?
NGLs are used as inputs for petrochemical plants, burned for space heat and cooking, and blended into vehicle fuel. Higher crude oil prices have contributed to increased NGL prices and, in turn, provided incentives to drill in liquids-rich resources with significant NGL content.
What is NGL 691?
NGC 691 is an unbarred spiral galaxy located some 125 million light-years away in the constellation of Aries. This galaxy was discovered by the German-born British astronomer William Herschel on November 13, 1786. It is the foremost member of the NGC 691 group, a collection of nine galaxies of varied shapes and colors.
What is the LNG process?
The conversion of natural gas to its liquefied form allows for the transport of greater quanti- ties. Liquefaction describes the process of cooling natural gas to approximately -162°C ( -259°F ) until it forms as a liquid. This process is known as the LNG Process Chain.
How is LPG recovered from natural gas?
A turboexpander reduces the pressure of the inlet gas to the outlet pressure, and it produces a cryogenic temperature, which aids in the recovery of NGL and LPG from the feed gas stream to meet hydrocarbon dewpoint specifications.
What is fractionated process?
Fractionation processes are processes of separation of mixtures of liquids, gases or solids into their components. Fractional separation is based on differences in a specific property of the individual components. Fractionation processes are physical processes, where phase transition is involved.
