$this->bbcode_second_pass_quote('me2', 'T')hat is the extraction side of things.
I am speaking of refining, where natural gas is used to make a high hydrogen contect gas which is used to crack the heavy oil into lighter crude.
Hmm, thanks for asking the question... it made me research that end of it.
$this->bbcode_second_pass_quote('', 'T')he Long Lake Project uses a unique combination of technologies to provide a solution to the natural gas supply and cost issue. A key component is a gasification facility using the Shell Gasification Process (SGP) which is integrated with the bitumen upgrading to convert the liquid asphaltene by-product stream into hydrogen for the secondary upgrading step and syngas fuel. An Air Liquide air separation unit (ASU) will provide high purity oxygen and other utility services to the upgrader.
Of course Long Lake is unique, but a good indicator of what the future will like. If you look at page 7, it looks like 20% of NG is used typically for upgrading. But it's a lot of tech gooble-di-goc, and I could be reading it incorrectly.
$this->bbcode_second_pass_quote('', 'A') key advantage of the Long Lake Integrated Upgrader configuration is the integration of an asphaltene gasification unit into the upgrader system to provide hydrogen to the hydrocracker and fuel for power and steam generation. The energy balance of the project, shown in Table 2, demonstrates the elimination of virtually all of the natural gas cost exposure, which results in an operating cost advantage of about 50% over currently-configured operations.
