High-Recovery Cryogenic Gas Plant | Schlumberger

Cryogenic Gas Plant

Available for immediate delivery to improve your NGL recovery

Employing the field-proven NGL-MAX process using semi-lean and lean reflux, this high-recovery cyrogenic gas plant can provide an ethane recovery rate of 97% and higher from natural gas streams. In comparison with conventional designs, this recovery represents a 10% increase in production revenue. In as little as three weeks, the preengineered, modular cryogenic gas plan can be started up and commissioned at your site.

With a throughput range from 160 to 225 MMcf/d, the high-recovery cryogenic gas plant provides numerous operational advantages.
