LONDON (ICIS)--Shale gas opportunities for players in the North American chemicals sector are beginning to be given some substance, but firm projects have yet to materialise.

Consultants had mulled the idea and economic analysis had been run, Gallogly said.
“There has been a little bit of discussion about some cracker capacity additions, but it’s so early on that it’s hard to call that credible," he added.
“We do think there is an ongoing ethane advantage, but at this time the market doesn’t need the capacity,” he said.
How sector firms build on the new shale gas advantage, apart from the expected obvious ethane price advantage, largely remains to be seen and there are clearly some big hurdles to be overcome.
Shale gas is often very rich in NGLs (natural gas liquids), and there is the question of just who separates gas from liquids.

A couple of the important gas fields look as though they might extend across the border into Canada, suggesting that advantage may be taken of extraction and liquids separation there.
Propylene generally also is tight - because of the overwhelming cost advantage for petrochemical producers to crack ethane - so possibly the opportunities lie more in that direction.
Dow Chemical CEO Andrew Liveris pointed to the propylene opportunities in an earnings conference call on Thursday.
"You can expect us to be more and more active on alternative ways to get propane into the mix," Liveris said when talking about the shale gas advantage.
Dow has taken its first shipment of propylene from PetroLogistics’ new 554,000 tonne/year propane dehydrogenation (PDH) unit in
Dow will eventually take half of the unit's output. The propylene is widely used within its expanded - and more specialty focused - materials portfolio.
"That will help us a lot on sourcing propylene that is back-integrated - so to speak - into the NGL mix versus tied to the refining pool," Liveris said. "It will give us an advantage that we didn't have before."
PDH units may be capital intensive - and notoriously difficult to run efficiently when the feedstock is not priced competitively - but consultants believe that they can produce more-than-worthwhile returns given the disparity between crude and natural gas prices.
Propylene prices over the past few years have run up much closer to ethylene - above ethylene at some points in the
PetroLogistics says its plant is flexible and can produce varying rations of chemical grade and polymer grade propylene (CGP and PCG).
Shale gas is definitely the game changer in the
