Houston-based Piñon Midstream commissioned its third sour gas treatment train at its Dark Horse Treating Facility and received a new source review (NSR) permit to continue expanding operations at the plant, according to a May 22 press release.

Piñon’s operations are centered in Lea County in southern New Mexico. The new train is a 450 gallons per minute (gpm) unit, which increases the facility’s overall sour gas processing capacity to about 270 MMcf/d.

With the NSR, the company has plans for a large-scale expansion at the site, including three 900-gpm sour gas treatment units, two cryogenic processing plants with a total processing capacity of 460 MMcf/d and 4,400 bbl of storage capacity.

“With the recent receipt of the NSR permit, Piñon is well-positioned to significantly expand our sour gas treating and carbon capture operations within the Delaware Basin,” Piñon CEO Steven Green said in the press release.

Piñon has grown its sour gas gathering system in the region and now owns and operates more than 15 miles of 16-inch high-pressure steel pipelines and five compressor stations on its network.
