Sasol to build the first gas-to-liquids plant in the US

South African oil and gas company Sasol (NYSE:SSL) has chosen southwest Louisiana as the location of its planned gas-to-liquids (GTL) facility. The first GTL plant in the United States, the Sasol facility would produce GTL transportation fuels and other products.

“We believe Sasol’s proprietary GTL technology can help unlock the potential of Louisiana’s clean and abundant natural gas resources and contribute to an affordable, reliable and high quality fuel supply for the United States,” said Sasol Managing Director: New Business Development Ernst Oberholster at a press conference with Louisiana Governor Bobby Jindal.

Over the next 18 months, Sasol will conduct a feasibility study to determine the possibility of building the GTL facility in Calcasieu Parish, Louisiana. The study will consider two development options. The first option includes a facility that would produce 2 million tons per year, and the second option would double that production rate.

In December 2010, Sasol revealed that the company will build the world’s first Ethylene Tetramerization Unit in Calcasieu Parish.

Clean-Burning Fuel Alternative

GTL transportation fuel is cleaner-burning than conventional diesel, but GTL has a comparable, or possibly lower, greenhouse gas profile. In addition to reducing emissions of particulates, nitrogen oxides, carbon monoxide and other pollutants that would improve air quality, GTL fuel is nearly free of sulfur and aromatic compounds.

“GTL fuels are an important part of the energy mix because they can advance energy independence in a way that is both cost-efficient and environmentally friendly,” Oberholster said.

Unlike other clean fuel alternatives, GTL fuel can be used in existing vehicles and fuel delivery infrastructure without any modifications.

Additionally, a Pricewaterhouse Coopers study in 2005 revealed that a GTL facility provides air quality benefits in comparison to an oil refinery due to lower sulfur dioxide, nitrogen oxide and hydrocarbon emissions.

New Market for Shale Gas

The state of Louisiana has extensive natural gas resources both in the conventional form and in the prolific Haynesville Shale formation in the state.

Gas drilling, development and production is currently being limited because the increase of natural gas production across the US due to shale developments has glutted the domestic market, sending natural gas prices very low.

While a number of companies are working to build LNG liquefaction facilities or convert existing gasification plants along the Gulf Coast to export natural gas to international markets, Sasol’s GTL facility would create a domestic market for the natural gas production.

Sasol converts gas and coal into liquid fuels, fuel components and chemicals through its proprietary Fischer-Tropsch process. In 2007, the South African company started its first international GTL plant, Oryx GTL, in partnership with Qatar Petroleum. The company is also looking to build a GTL plant in Uzbekistan and has launched a feasibility study for another GTL plant in Western Canada to produce fuels from the Montney Shale.



GTL diesel is of significant higher quality than diesel derived
from crude oil. GTL diesel has a high cetane number (at least
70 compared with a 45 to 55 rating of most diesels), low
sulphur (less than five parts per million), low aromatics
(less than 1%), and good cold flow characteristics, which
can be optimised to suit specific applications.
GTL diesel is positioned as a clean, premium product or as a blend
stock to enhance the quality of conventional diesels.
Best of all, GTL diesel can be used in all modern diesel engines.
Its high-quality properties result in reduced noise and other
performance benefits. The high cetane number and very low
levels of sulphur and aromatics ensure a more efficient and
cleaner-burning combustion environment. This leads to a
substantial reduction in engine wear and exhaust emissions.
Significantly, too, GTL diesel is compatible with established fuel
distribution infrastructures. It can therefore be distributed by ship,
road tanker or rail tanker without transport operators having to
undertake new investments to modify their equipment. It can
also be used with both current and envisaged future engine
and exhaust technologies. Compression-ignition vehicles using
GTL diesel do not need to undergo any engine or exhaust
system modifications.
GTL ventures offer other benefits. A high-quality GTL naphtha is
also produced in the Fischer-Tropsch process. With a high content
of paraffins and very low contents of sulphur, naphthenes and
aromatics, it is ideal as cracker feedstock to produce ethylene for
the plastics industries (mostly for producing polyethylene and
polyvinyl chloride).

 

70 Cetane!!!!!

Where do I get some for my truck???

 

2.5 gear ratio in a truck?? Bet that duck aint got no cluck on the hills!!

 

go two pages back

scania with 2.07 diff ratio cruising speed at 960rpm

point is truck have automated transmission and when going uphill it will make downshift earlier , since automated transmission is much faster than manual you wont feel any difference in pulling

however who drive over heavy hills often and off highway will need shorter differential for better overall lifetime because you keep it in higher gear


largest problem is on city driving with stop-start because truck often struggle to accelerate and it can use even more fuel than short transmission truck

now 2.59diff ratio and similar is already standard here

as i can see volvo presented xe in US so i guess other manufactures will fallow this lead.....personally i was also very skeptical to long transmission but once i try it it works well cruising speed of 1030rpm works well even on largest mountains

please delete..... i make double same post

 

You run that fast of a ratio with a direct drive transmission (1:1), not with a reduction tranny (.73:1 or .74:1).

 

Yeah that would make sense!
