Membrane System for Recovery of Volatile Organic Compounds from Remediation Off-Gases.: Phase 1.

In situ vacuum extraction, air or steam sparging, and vitrification are widely used methods of remediating soil contaminated with volatile organic compounds (VOCs). All of these processes produce a VOC-laden air stream from which the VOC must be removed before the air can be discharged or recycled to the generating process. Treatment of these off-gases is often a major portion of the cost of the remediation project. Carbon adsorption and catalytic incineration, the most common methods of treating these gas streams, suffer from significant drawbacks. This report covers the first phase of a two-phase project. The first phase involved the laboratory demonstration of the water separation section of the unit, the production and demonstration of new membrane modules to improve the separation, the design studies required for the demonstration system, and initial contacts with potential field sites. In the second phase, the demonstration system will be built and, after a short laboratory evaluation, will be tested at two field sites

Field Demonstration of a Membrane Process to Recover Heavy Hydrocarbons and to Remove Water From Natural Gas Annual Report

The objective of this project is to design, construct and field demonstrate a 3-MMscfd membrane system to recover natural gas liquids (NGL) and remove water from raw natural gas. An extended field test to demonstrate system performance under real-world conditions is required to convince industry users of the efficiency and reliability of the process. The system will be designed and fabricated by Membrane Technology and Research, Inc. (MTR) and then installed and operated at British Petroleum (BP)-Amoco's Pascagoula, MS plant. The Gas Research Institute will partially support the field demonstration and BP-Amoco will help install the unit and provide onsite operators and utilities. The gas processed by the membrane system will meet pipeline specifications for dewpoint and Btu value and can be delivered without further treatment to the pipeline. Based on data from prior membrane module tests, the process is likely to be significantly less expensive than glycol dehydration followed by propane refrigeration, the principal competitive technology. At the end of this demonstration project the process will be ready for commercialization. The route to commercialization will be developed during this project and may involve collaboration with other companies already servicing the natural gas processing industry

Treatment of Organic-Contaminated Wastewater by Pervaporation

The removal and recovery of organic contaminants from aqueous streams by pervaporation membrane systems is a viable and economical treatment for many waste streams. Specific opportunities for the technology are identified in this paper. Laboratory and pilot system data are used to develop system designs and to calculate the cost of treating specific streams
