Treatment of Produced Waters Using a Surfactant-Modified Zeolite/Vapor-Phase
This project was funded through DOE's Natural Gas and Oil Technology Environmental
Program in support of Produced-Water Management.
The goal is to characterize and optimize the Surfactant-Modified Zeolite (SMZ)
primary and secondary regeneration processes to enable long-term operation of
the SMZ process for a wide range of produced water applications.

SMZ has been studied and characterized, providing an improved understanding
of how the zeolite works for use in the vapor-phase bioreactor (VPB).
SMZ processing will facilitate onsite treatment of produced water, which will
allow significant reduction in operating costs for oil and gas producers.
SMZ is an innovative filtration/sorption medium that has been shown to remove
contaminants such as BTEX (benzene, toluene, ethylbenzene, and xylenes) from
produced waters. Cost-effective operation of an SMZ requires a method of regenerating
the SMZ on-ite. Evaluation and design of the regeneration method for the SMZ
process was not fully addressed in previous research at Los Alamos and the University
The project worked on the development of the VPB in conjunction with the University
of Texas. Analysis of the waste gas composition in the VPB was completed. The
performance of the VPB is undergoing testing.
Current Status (October 2005)
The project was conducted informally as part of the research with ongoing projects
at the University of Texas.
