Abstract:
The adage, ‘the customer is always right’, applies to the helium production and distribution industry. Customers may be looking for a gaseous industrial grade, say 70% He, an A-Grade gaseous product (say 99·99% He) or a very pure liquid product with a purity of >99·995% He. To produce the two higher grades cryogenics will be required. When cryogenically producing liquid helium (LHe) or very pure gaseous helium, liquid nitrogen (LN2) and/ or gaseous N2 will be a co-product. Nitrogen can be a useful and valuable co-product that can assist petroleum exploration and production. The co-production of helium and nitrogen can be win-win activity; this is the theme of this article.
