In 2012, it said, US gas plants produced on average 971,000 b/d of ethane. Potential ethane supply growth will substantially exceed the roughly 137,000 b/d of ethane demand growth by way of ...

Anything that would impede the purified natural gas—water, propane, butane, mercury—is also filtered out. Left with mostly pure methane and some ethane, these gases are sent to heat exchangers.

Propane and ethane prices already are down about 25% and 15%, respectively, since March with more downward momentum anticipated, said Kristen Holmquist, managing director of analytics for RBN Energy.

Atmospheric non-methane hydrocarbon concentrations began declining in the 1970s. Surface and column measurements show that Northern Hemisphere ethane concentrations are now rising, probably due to ...

Ethane is more of a problem for air pollution than greenhouse warming. "We didn't look at any of the methane data at all and we still see the same results as everyone else," he said.

Whereas the ethane and propane data do seem to rule out a biological source, there are many ways natural gas can seep into the water supply. "It’s hard to say which hat a rabbit came from when ...

A new study of US NGL markets from Simmons & Co. International, Houston, sees ethane remaining in oversupply near term and export growth bringing balance to propane and butane markets. The ...
