QatarEnergy. 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. [1] 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% ...
The raw gas is then piped to a gas processing plant where the initial purification is usually the removal of acid gases (hydrogen sulfide and carbon dioxide). There are several processes available for that purpose as shown in the flow diagram, but amine treating is the process that was historically used. However, due to a range of performance ...
A liquefied natural gas ship at Świnoujście LNG terminal in Poland. Liquefied natural gas ( LNG) is natural gas (predominantly methane, CH 4, with some mixture of ethane, C 2 H 6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the ...
QatarEnergy LNG. QatarEnergy LNG, formerly Qatargas, is the world's largest liquefied natural gas (LNG) company. It produces and supplies the globe with 77 million metric tonnes of LNG annually from across its seven ventures—QatarEnergy LNG N (1), QatarEnergy LNG N (2), QatarEnergy LNG N (3), QatarEnergy LNG N (4), [1] RL1, RL2 and RL3.

Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases. [1] [2] [3] It is a common unit process used in refineries, and ...
Regasification. Regasification is a process of converting liquefied natural gas (LNG) at −162 °C (−260 °F) temperature back to natural gas at atmospheric temperature. LNG gasification plants can be located on land as well as on floating barges, i.e. a Floating Storage and Regasification Unit (FSRU). Floating barge mounted plants have the ...
A process flow diagram ( PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations. Another commonly used term for a PFD is ...
The image below is a schematic flow diagram of a typical petroleum refinery that depicts the various refining processes and the flow of intermediate product streams that occurs between the inlet crude oil feedstock and the final end-products. The diagram depicts only one of the literally hundreds of different oil refinery configurations.
