Bubbleless gas transfer technology for the in situ remediation of chlorinated hydrocarbons

Description: The primary objective of this project is to demonstrate the ability of hydrogen to supply reducing equivalents for the reductive dehalogenation of perchloroethylene (PCE). This objective will be accomplished by two types of activities. First, laboratory experiments will compare the kinetics of hydrogen-mediated dehalogenation with natural routes of loss (hydrolysis and natural attenuation). Secondly, bench-scale column experiments will be performed to demonstrate hydrogen-mediated reductive deh… more

The Federal Energy Technology Center annual site environmental report for calendar year 1998

Description: A comprehensive Directives Program aimed at environmental, safety, and health requirements and risks was initiated in 1997 and will be completed in late 1999 or early 2000. The primary objective of the program is to identify or develop a set of standards that, when implemented, provides reasonable assurance that the health and safety of the workers, public, and the environment will be protected during the performance of the work. In conjunction with the Directives Program, the use of the volunt… more

HEMISPHERIC CENTER FOR ENVIRONMENTAL TECHNOLOGY

Description: The Deactivation and Decommissioning (D&D) Technology Assessment Program (TAP) was developed to provide detailed, comparable data for environmental technologies and to disseminate this data to D&D professionals in a manner that will facilitate the review and selection of technologies to perform decontamination and decommissioning. The objectives for this project include the following: Determine technology needs through review of the Site Technology Coordination Group (STCG) information … more

LLNL heart valve condition classification project anechoic testing results at the TRANSDEC evaluation facility

Description: This report first briefly outlines the procedures and support/activation fixture developed at LLNL to perform the heart valve tests in an anechoic-like tank at the US Navy Transducer Evaluation Facility (TransDec) located in San Diego, CA. Next they discuss the basic experiments performed and the corresponding experimental plan employed to gather meaningful data systematically. The signal processing required to extract the desired information is briefly developed along with some of the data. Fi… more

Molecular-Level Processes Governing the Interaction of Contaminants with Iron and Manganese Oxides - Final Report

Description: Many of the inorganic and organic contaminants present in sediments at DOE sites can be altered or destroyed by reduction and oxidation (redox) reactions occurring at mineral surfaces. A fundamental understanding of such redox processes provided by molecular-level studies on structurally and compositionally well-defined mineral surfaces will lead to: (i) improved models of contaminant fate and transport in geochemical systems, and (ii) optimized manipulation of these processes for remediation p… more

Studies in combustion and explosion

Description: The objective of the proposed research is to investigate the influence of various aerodynamical, diffusive-thermal, radiative and reaction-rate factors on certain fundamental phenomena concerning combustion and explosion of gaseous premixtures. Different modeling techniques will be employed to reduce the study of pertinent physical systems to simple approximate problems tractable either analytically or numerically. Specifically the authors plan to study: (1) fluid dynamical aspects of flame anc… more

TECHNOLOGY TRANSFER TO U.S. INDEPENDENT OIL AND NATURAL GAS PRODUCERS

Description: During FY99, the Petroleum Technology Transfer Council (PTTC) continued pursuing its mission of helping U.S. independent oil and gas producers make timely, informed technology decisions. PTTC's national organization has active grassroots programs that connect with independents through its 10 Regional Lead Organizations (RLOs). These activities--including technology workshops, resource centers, websites, newsletters, and other outreach efforts--are guided by regional Producer Advisory Groups (PA… more
