Management of Soluble Organics in Produced and Flowback Waters with Swellable, Absorbent Glass
Abstract:Osorb®, an absorbent, nano-engineered glass, is being commercialized to remove soluble organics like BTEX and other volatile organic compounds (VOCs) from oilfield produced and flowback waters for the purposes of beneficial reuse, membrane protection, air emission controls, and offshore excursions. The Osorb is reusable, utilizing one or more of centrifugal, thermal, and vacuum regeneration processes. Two pilot water treatment systems are currently being fielded, and a commercial 5 bpm system is undergoing final engineering. PWUnit#1.5 is a fully automated, mobile system that polishes soluble organics from water at 246 L/min. The design parameters for PWUnit#1.5 are based on the manually operated PWUnit#1. Final engineering is being completed for the 798 L/min PWUnit#2, which includes closed-loop water treatment and Osorb regeneration. Excursion Unit#1 is a 160 L/min, fixed-bed system designed for polishing soluble organics from produced water prior to overboard discharge during offshore excursions.
