What is difference between LNG and NGL?

LNG–Liquefied natural gas, is gas that has been compressed at very low temperatures and is transported as a liquid. Primarily methane. NGLNatural Gas Liquids, heavier hydrocarbons that have been extracted from field gas for use as a feedstock in chemical plants.

What are NGL products?

Natural gas liquids (NGLs) are hydrocarbons—in the same family of molecules as natural gas and crude oil, composed exclusively of carbon and hydrogen. Ethane, propane, butane, isobutane, and pentane are all NGLs (see table above).

How is NGL produced?

By definition, NGL production happens at natural gas processing plants and petroleum refineries, but between 2009 and 2016, all of the growth in NGL production occurred at natural gas processing plants as a byproduct of processing the growing supply of natural gas from shale gas and tight oil formations.

What is a Deethanizer?

The deethanizer (DER) operates at about 450 psia and. separates ethane from the propane and heavier components. Because the critical temperature of ethane is about 90oF, the condenser of the deethanizer must be refrigerated.

Is condensate dangerous?

HOW DANGEROUS IS CONDENSATE? Like all fossil fuels, condensate contains toxicants which are harmful to the environment, animals and humans. It is generally more flammable and explosive than normal crude oil.

Is LPG and NGL the same?

LPG is isolated from the hydrocarbon mixtures by its separation from natural gas or by the refining of crude oil. Natural gas liquids (NGL) range from 1% to 10% of the natural gas flow. Similarly, LPG produced from crude oil refining constitutes between 1% and 4% of the crude oil processed.

Is natural gas the same as butane?

Natural gas is found underground, and it contains several different gases, including butane, propane, and methane. It can be a liquid or a compressed or uncompressed gas. Propane, also called liquefied petroleum gas or LPG, is stored as a liquid after it’s separated from natural gas at a processing facility.

Is LPG liquid or gas?

At normal temperature and pressure – as in your living room or garden – you will meet LPG as a gas. But when it is either cooled down or put under pressure, it changes into a liquid. Exactly the type of liquid that is filled onto the cylinders you use for your BBQ in the summer.

Why is it called Y grade?

The story is that Ygrade got its name from an old Texas pipeline company that assigned different letters to the various products that they shipped. Ygrade was the designation for the natural gas liquids mix.

Why are NGL prices so low?

NGL prices have eased largely due to strong U.S. upstream production, focused in the key plays and basins – namely the Permian Basin and its sub-plays. But there’s limited U.S. demand growth to absorb that production. U.S. butane and propane markets, for example, are considered “mature.”

Is condensate and NGL the same?

In U.S. usage, a “plant condensate” is the equivalent of products classified as “pentanes+” and natural gasoline, and these are considered NGLs. On the other hand, U.S. usage typically does not consider “field or lease condensate” as an NGL, instead classifying these commodities as crude oil.

Is ethane a liquid or gas?

What is ethane? Ethane (C2H6) is a colorless, odorless combustible gas that is part of the mixture known as natural gas. It is a naturally-occurring hydrocarbon that can be found underground in liquid form in rock formations, such as shale and coal beds, including the Marcellus and Utica shale formations.

How does a Deethanizer work?

In short, the answer is: initially liquid, and then both liquid and gas. The point of the deethanizer is to separate the methane, ethane and other things. The initial incoming stream is liquid which falls and separates. Then a gas (c2) gets reintroduced and rises.

What is a demethanizer column?

DEMETHANIZER – this fractionation column is stainless steel and carbon steel. It is designed for approximately -150 (top)150oF (bottom) @ 560 psi. They are typically over 100 feet long. The biggest fraction of natural gas is the methane. It is about 95% of the total volume.

How do you separate butane and propane?

Depropanizer extracts propane from propane + and sends the remaining mixture, called butane cut +, to the debutanizer. The debutanizer extracts butane from butane + and the remaining products are called condensates or pentane +. The splitting is then complete.
