You should have wiki'd up that knowledge before you pretended to understand that the title of the thread was Gas-To-Paint or Gas-To-Fertilizer. And then missed the idea that the Pearl plant made jet fuel for the Qatar airlines, just like it did engine oils available at your local walmart. All of these things I've mentioned are LIQUIDS, just like the title says.

Why don't you and the wife adopt a 6 year old Chinese child, teach them a months worth of English and let them post in your stead, the entire flavor of this place would change if you added that level of intelligence to your posting.

I'd call it cool, interesting, and a good start. But we're a LONG way from a practical, affordable solution on a planetary scale, IMO.


according to EIA more than 90% of total global GTL output comes from 4 projects, two in Qatar, one in South Africa and one in Nigeria. Using EIA reference price scenario they see no new large-scale GTL plants being built due to economics. They suggest there will be modular small-scale plants built (~5000 bpd capacity) but again due to economic constraints “Production from small-scale GTL plants is not a significant contributor to volumes of petroleum liquids by 2040".

These economic constraints are noted in global LNG markets as well where the addition of a number of new volumes to global trade has resulted in a global gas price that tracks somewhere between LNG operating cost and full cycle export costs.

The largest, Pearl GTL has been operating at half planned capacity for a while, due to unplanned "maintanance"
In 2003, the project cost was estimated to be US$5 billion. However, after facing huge cost escalation, it was reported to be $18 billion in 2007,[1] and, according to Qatar Petroleum sources, final project cost is expected to reach as high as $24 billion.[9] Because Shell's contract provided them with the input gas for free, the project was calculated to be viable once the price of oil exceeded $40 per barrel.[10]

Is it viable at $70? Perhaps

From this and the rest of this thread, it seems like GTL for liquid fuels is only borderline economically viable -- its viability is very sensitive to the relative prices of natural gas and crude oil.

However, GTL for specialty hydrocarbons like motor oil seems to be thriving. I think that it is more successful there because (1) one needs much less lubricant than fuel and (2) GTL lube has demonstrably superior performance. This makes a price premium much more tolerable.

I hope that I have gotten the economics straight.
