Perhaps the Definitive Post on The CRYO Plants West of Williston -- The Bakken, North Dakota, USA

"Anonymous" sent an incredibly informative comment to my posting regarding the natural gas processing plants going up west of Williston. It was too important to be left as a comment only, so here is the entire comment. I will add my thoughts at the bottom, later.

Linde will not be the owner of these plants: ONEOK Partnerships will be the owner and operator.

Linde does operate its own cryogenic plants for oxygen / nitrogen / argon etc, but, as a side business, also has a chemical engineering design/project group that provides chemical process design/construction business to the natural gas business. Pipeline companies like ONEOK rely on Linde and other E&C companies for those services.

Here's a list of nat gas plants Linde has designed, which are generally smaller type plants, not the huge scale plants seen mostly in Texas and Louisiana:

Larger NG plants are not Linde's expertise (more appropriate for Fluor Daniel or some other large-scale chemical process design and construction firm).

Here's a synopsis of U.S. natural gas plants, which show that the new ND plants, while significant to the local economy, have relatively small capacity.
