Helium Recovery

Helium Recovery and Purification

 

There are some helium containing gas wells in every one of the contiguous North American States. Usually these occur where high nitrogen content gas is found. So, you may wonder, why don’t more companies recover helium, especially at today’s prices when helium has four times the value of the equivalent volume of natural gas. The conventional wisdom is that the cost to extract helium is so exorbitant that the processing only makes economic sense with large volume of gas where the helium content exceeds 0.3 mole percent. Azota believes that as the scarcity of this rare gas increases, more businesses will investigate the possibility of recovering the helium they are currently venting or sending down the sales pipeline.

 

Helium Supply and Demand

 

The United States Bureau of Mines auctioned most of its helium reserves and with its supply depleted sells only to U.S. government users. This exhausted reserve means that continuing supply will eventually have to come from other sources. An excellent description of the long-term helium supply issue may be found at the website of Helium 1: http://www.helium-one.com/helium-market/

Azota and Helium Recovery

 

The Azota team’s first helium recovery plant was located in Utah’s Lisbon Valley. This plant was designed and built in 1988 in conjunction with a nitrogen rejection unit and liquids recovery plant and remains in operation to this day. We have continued to expand our helium recovery capabilities since then. Today, we have solutions to the increasing need for helium recovery even in situations previously thought to be uncommercial.

Cryogenic Recovery

 

Helium recovery plants are typically associated with nitrogen rejection units (NRU’s).  These deep cryogenic plants permit the integration of the helium recovery equipment particularly if the need is foreseen before the NRU design and construction. Helium recoveries can be more than 98%.

Adsorption Recovery

 

A non-cryogenic process may also be used for the recovery of helium. Based upon the same pressure swing adsorption technology used for helium and hydrogen purification, these units are dependable, robust, and commercially viable for many smaller applications.
