RasGas

RasGas is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand RasGas rather than just read about it. In short: RasGas Company Limited was a liquefied natural gas (LNG) producing company in Qatar. It was the second-biggest LNG producer in Qatar after QatarEnergy LNG.

Key takeaways

RasGas belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect RasGas to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of RasGas from memory before moving on to harder problems.

Reference excerpt

RasGas Company Limited was a liquefied natural gas (LNG) producing company in Qatar. It was the second-biggest LNG producer in Qatar after QatarEnergy LNG. RasGas operated seven LNG trains located in Ras Laffan Industrial City. It was merged with Qatargas on 1 January 2018. RasGas also operated helium plants which produce 25% of the world's helium, and make Qatar the second largest helium exporter. The chief executive officer of the company was Hamad Mubarak Al-Muhannadi.

History

Ras Laffan LNG, commonly known as RasGas, was the name of one of the two initial LNG projects in Qatar, which were founded in and together with the Ras Laffan Industrial Complex in the 1990s. The project was initiated by Qatargas together with its partner ExxonMobil, and later also included other foreign investors. The project started production in 1999. The company RasGas was then established in a joint stock company between QatarEnergy and ExxonMobil in 2001. It was set up as the operating company for the production facilities based in Ras Laffan Industrial City, Qatar. During the early 2000s, RasGas started operating additional LNG facilities (LNG trains) and signed several long-term sales agreements with South Korea, India and other countries. Train 6 came online in October 2009, and was inaugurated on 27 October 2009. Sheikh Hamad bin Khalifa Al-Thani, the Emir of Qatar, attended the ceremony. Train 7 started production in February 2010. Both trains produce 7.8 million tonnes of LNG per year and they among the largest LNG trains in the world. In 2007, RasGas started talks for a new gas project in order to meet continually growing local demand. In 2011, the company then closed a $10.5 billion financing deal for the Barzan Gas project, adding a gas production capacity of 1.4 bcf/day. Construction for the projects two trains began in 2011 and was expected to finish by late 2014 / early 2015. The project was then expected to come online in October 2016, but was further delayed because of technical challenges. In 2013, RasGas became the victim of a series of Cyberattacks, which together with attacks on Saudi Aramco and other companies, were attributed to Iran's "cybercorps". In 2016, RasGas celebrated its 10,000th LNG vessel loading at Ras Laffan Industrial City's port. Rasgas was merged with Qatargas on 1 January 2018. The merger had first been announced in 2016 and was implemented on time.

Organization From 2006 to 2011, Mohammed Saleh Al Sada served as the managing director of RasGas.

Operations RasGas operations consisted of the extraction, processing, liquefaction, storage and export of LNG and all associated derivatives from Qatars North Field. The company's seven LNG trains had a total capacity of 36.3 million tonnes of LNG per year. Trains 1 and 2 were owned by Ras Laffan, and they have a combined capacity of 6.6 million tonnes of LNG per year. Ras Laffan (II) owns Trains 3, 4 and 5 with a capacity of 4.7 million tonnes of LNG per annum each. Trains 6 and 7 are owned by Ras Laffan (3). RasGas operated Helium 1 and Helium 2 helium plants. Helium 1 produces 660 million cubic feet per year (19 million cubic metres per year) of liquid helium, which is approximately 10 percent of the world's total helium production. Helium 2 is the world's largest helium refining facility. It produces 1.3 billion cubic feet per year (37 million cubic metres per year) of liquid helium. Together, these two plants now produce 25% of the world's helium, making Qatar the second largest world helium exporter, after the U.S. RasGas also operated the Al Khaleej Gas Projects, AKG-1 and AKG-2, which supply a daily average of around 2.0 billion cubic feet (57 million cubic metres) at standard conditions to Qatar's network of pipelines, delivering gas for the growing domestic market.

Worked examples

Example 1 — a first encounter with RasGas

Start with the simplest possible case. Write down what RasGas claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to RasGas before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about RasGas ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of RasGas

In research: RasGas appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses RasGas in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: RasGas is common in secondary-school and first-year university syllabi. It links to neighbouring topics Energy companies established in 2001, Former ExxonMobil subsidiaries, Helium, so understanding it makes those chapters shorter.
In everyday life: Look for RasGas outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is RasGas in simple terms?

RasGas Company Limited was a liquefied natural gas (LNG) producing company in Qatar. It was the second-biggest LNG producer in Qatar after QatarEnergy LNG.

Why does RasGas matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study RasGas?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
