Euan,
With regards to Hawiyah production from the Permian Khuff, the articles I read stated unequivocally that the liquids production was Natural Gas Liquids, NOT Liquefied Natural Gas. The link you posted (http://www.hydrocarbons-technology.com/projects/saudi-aramco/) is pretty clear on that.
Current NGL production is 170 kbpd, scheduled to rise to 480 kbpd by the end of 2007.
As far as I am aware, there is no present or planned production of Liquefied Natural Gas in Saudi Arabia.
Yes - but ethane - C2H6 - is a light gas that will only go liquid if cooled. Methane (CH4), Ethane, Propane and Butane are all gasses. It is only when you get to Hexane (C6H14) and higher chanes that you would call it NGL.
I'm not 100% sure on this but it was the comment about 310,000 bbls bpd ethane that led me to say the report was equivocal.
Ethane is used in LPG (liquified petroleum gas) in varying proportions together with propane.
http://en.wikipedia.org/wiki/Liquified_petroleum_gas
LPG drives many taxis in Australia. It is liquid under pressure and ambient temperature and therefore requires a special tank which is fitted in the boot
I think propane and butane compress to a a liquid at ambient temp.
Ethane would be too high a pressure for basic domestic use. And it's a chemical feedstock, so too useful to burn??
i think you are refering to condensate (c6+). which is more or less stable at stock tank conditions. lpg (primarily propane) is stored in a pressurized vessel. ngl refers to the whole range of intermediate components (c2 - c6) which can be liquified by cooling and are components of gasoline and chemical feedstocks. lng is liquified methane.
and with all of these designations, it is important to remember that they arent a pure single component. condensate will contain a small fraction of methane for example.
methane b.p. -161 ºC, ethane b.p. -88 ºC , propane b.p. -42.1 ºC, butane b.p. -0.5 ºC, pentane b.p. 35-36 ºC and hexanes 68-70 ºC
