Chemical phenomena occurring at boundaries between insulating solids and liquids (adsorption, partition, monolayer self-assembly, catalysis, and chemical reactions) are important to energy-related analytical chemistry. These phenomena are central to chromatography, solid-phase extraction, immobilized analytical reagents, and optical sensors. Chemical interactions in these processes cannot generally be identified solely by equilibrium surface concentrations, since the steady-state behavior does not reveal the mechanism or rates of surface reactions. Goal therefore is to develop surface-sensitive spectroscopies by which chemical kinetics at liquid/solid interfaces can be observed on time-scales from nanoseconds to seconds. In the first year, we have used Joule-discharge heating kinetics to study pore structure of silica gels; effects of pore diameter, particle size, and chemical modification on pore connectivity were investigated. Temperature-jump relaxation measurements of sorption/desorption kinetics at liquid/solid interfaces were also carried out using Joule heating; kinetic barriers to sorption of ions from solution were found for both C18 and Cl surfaces. Through a collaboration with Fritz-Haber Institute in Berlin, we were able to acquire laser temperature-jump data on kinetics at liquid/solid interfaces using a colloidal sample. We also quantified the rate of migration of covalently attached ligands on silica surfaces; from the temperature dependence, the large energy barrier to …

This report describes batch and anion exchange column laboratory-scale studies investigating ex situ methods to remove chromate (chromium [VI]), nitrate (NO{sub 3}), and uranium (present as uranyl (uranium [VI]) carbonato anionic species) from contaminated Hanford Site groundwaters. The technologies investigated include chemical precipitation or coprecipitation to remove chromate and uranium, and anion exchange to remove chromate, uranium, and nitrate. The technologies investigated were specified in the 100-HR-3 Groundwater Treatability Test Plan (DOE-RL 1993). The goal of these tests was to determine the best method to remove selected contaminants to below the concentration of the project performance goals. The raw data and observations made during these tests can be found in the Westinghouse Hanford Company (WHC) laboratory notebooks (Beck 1992, Herting 1993). The method recommended for future study is anion exchange with Dowex 21K resin.

The Strategic Petroleum Reserve serves as one of the most important investments in reducing the Nation`s vulnerability to oil supply disruptions. This Quarterly Report highlights activities undertaken during the third quarter of calendar year 1993, including: inventory of petroleum products stored in the Reserve, under contract and in transit at the end of the calendar quarter; fill rate for the quarter and projected fill rate for the next calendar quarter; average price of the petroleum products acquired during the calendar quarter; current and projected storage capacity and plans to accelerate the acquisition or construction of such capacity; analysis of existing or anticipated problems with the acquisition and storage of petroleum products and future expansion of storage capacity; funds obligated by the Secretary from the SPR Petroleum Account and the Strategic Petroleum Reserve Account during the prior calendar quarter and in total; and major environmental actions completed, in progress, or anticipated. Samples of the oil revealed two problems that, although readily correctable, have reduced the availability of some of the oil inventory for drawdown in the near-term. These problems are: (1) a higher-than-normal gas content in some of the crude oil, apparently from years of intrusion of methane form the surrounding …

In the present study we are studying the effects of including carbon dioxide, ozone, methane, and the halocarbons in addition to water vapor in the radiating atmosphere. The study has focused on two principal issues: the effect on the spectral fluxes and cooling rates of carbon dioxide, ozone and the halocarbons at 1990 concentration levels and the change in fluxes and cooling rates as a consequence of the anticipated ten year change in the profiles of these species. For the latter study the water vapor profiles have been taken as invariant in time. The radiative line-by-line calculations using LBLRTM (Line-By-Line Radiative Transfer Model) have been performed for tropical (TRP), mid-latitude winter (MLW) and mid-latitude summer (MLS) model atmospheres. The halocarbons considered in the present study are CCl{sub 4}, CFC-11, CFC-12 and CFC-22. In addition to considering the radiative effects of carbon dioxide at 355 ppM, the assumed current level, we have also obtained results for doubled carbon dioxide at 710 ppM. An important focus of the current research effort is the effect of the ozone depletion profile on atmospheric radiative effects.

This report describes the execution of the CONVEX Liner Add-On to the DIAMOND FORTUNE low-yield cavity test of the Defense Nuclear Agency. CONVEX stands for COntained Nuclear Vessel EXperiment. It concerns the design of underground chambers where repeated low-yield nuclear explosions could be conducted. The approach proposed by the first author in the early 1980`s was to engineer a steel-lined rock cavern where the steel liner would be prestressed against the rock by tendons and/or bolts. These would daylight in tunnels surrounding the main cavity. From there, they could be initially tensioned and retensioned, if needed, after each test. The CONVEX Liner Add-On to DIAMOND FORTUNE consisted of anchoring a 1.4-m square, 2.5-cm thick steel plate to the wall of the cavity, using a 5-cm diameter center bolt, and four 2.5-cm diameter comer bolts. The bolts daylighted in a drift surrounding the gallery, and separated from it by a 9-m thick rock pillar. The liner plate, the bolts, and the rock pillar were equipped with 23 gages to describe the thermal and mechanical response of the system during pretensioning, during the dynamic loading phase, and post-test. Particular emphasis was given to obtaining the response both upon loading and during the …

The CZD process involves injecting a finely atomized slurry of reactive lime into the flue gas duct work of a coal-fired utility boiler. The principle of the confined zone is to form a wet zone of slurry droplets in the middle of the duct walls. The lime slurry reacts with part of the SO{sub 2} in the gas, and the reaction products dry to form solid particles. A solids collector, typically an electrostatic precipitator (ESP) downstream from the point of injection, captures the reaction products along with the fly ash entrained in the flue gas. The demonstration is being conducted at Penelec`s Seward Station, Unit No. 15. This boiler is a 147 MWe coal-fired unit, which utilizes Pennsylvania bituminous coal (approximately 1.2 to 2.5% sulfur). One of the two flue gas ducts leading from the boiler has been retrofitted with the CZD technology. The first existing ESP installed in the station is immediately behind the air preheater. The second ESP, installed about 15 years ago, is about 80 feet away from the first ESP. The goal of this demonstration is to prove the technical and economic feasibility of the CZD technology on a commercial scale. The process is expected to …

The high-severity co-processing long-term operability test and the detailed product analyses from the operability test have been completed. Operational data and detailed product analyses have been used to characterize the high-severity co-processing operation. Using the process characterizations, yield estimate for a commercial-sized high-severity co-processing unit has been performed using operational data and detailed product analysis from the long-term operability study. The estimate is based on a co-processing unit processing the vacuum resid from 50,000 barrels per day (BPD) of Lloydminster crude and also processing 2,400 metric tons per day (MT/day) of Illinois No. 6 coal. The feedstock characteristics for the yield estimate are summarized in Table 1.
