Control of a catalytic fluid cracker

Description: Control offers an important tool for savings in refineries, mainly by integration of process models into on-line control. This paper is part of a research effort to better understand problems of partial control; control of a Fluid Catalytic Cracker (FCC) is used as example. Goal is to understand better the control problems of an FCC in context of model based control of a refinery, and to understand the general problem of designing partial control systems.

Particle size distribution of ground ITP washed precipitate for estimating filter box radioactive cesium release during transfer

Description: Synthetic washed ITP slurry (200 g) was oven dried for three days at 60--65{degrees}C in a pan, to a hard solid that stuck to the pan bottom. Between the cracks that formed were a few small particles of unknown size. The solids that were stuck to the pan bottom were pried free and repetitively ground in a mortar and pestle until they all passed through a 40 mesh sieve. This product was then sieved into 50, 80, 100, 170, 200, 325 sieve fractions and the results plotted. A protion of the fines pa… more

Complex source rate estimation for atmospheric transport and dispersion models

Description: The accuracy associated with assessing the environmental consequences of an accidental atmospheric release of radioactivity is highly dependent on our knowledge of the source release rate which is generally poorly known. This paper reports on a technique that integrates the radiological measurements with atmospheric dispersion modeling for more accurate source term estimation. We construct a minimum least squares methodology for solving the inverse problem with no a priori information about the… more

Demonstration of no feasibility of a Crystalline Beam in a Betatron Magnet

Description: This technical report investigates the feasibility of a Crystalline Beam in a weak-focussing storage ring like a Betatron. At the same time the curvature effect due to the bending magnet is also investigated. As a special case, the example of a circular one-dimensional string of electrically charged particles is examined. It is found that the motion of the particles is unstable due to the dependence of the precession movement with respect to each other on their radial displacement. That is a fo… more

Characterization of multiphase fluid flow during air-sparged hydrocyclone flotation by x-ray CT. Twelfth quarterly report, 14 May--13 August 1993

Description: During this quarter some experiments from the previous set were repeated to check the reproducibility of the results. Also, a new set of experiments was carried out to study the effects of (1) collector dosage, (2) Q* -- the nondimensional ratio of air flow rate to slurry flow rate, and (3) slurry pressure on the flow characteristics. Four different Q* values with hydrophobic particles in the feed slurry were studied. The value of A*, the dimensionless ratio of overflow opening area to underflo… more

Description: ADA Technologies, Inc. (ADA) has completed the bench-scale testing phase of a program to evaluate additives that will improve the collection of fine particles in electrostatic precipitators (ESPs). A bench-scale ESP was installed at the Consolidation Coal Company (CONSOL) combustion research and development facility in Library, PA in order to conduct the evaluation. During a two-week test, four candidate additives were injected into the flue gas ahead of a 100 acfm ESP to determine the effect o… more

Restricting Softwood Log Exports: Policy and Legal Implications

Description: The Pacific Northwest is a major exporter of unprocessed softwood logs to foreign countries, such as Japan, that are often sold at premium prices. Consequently, some local mills have had difficulty obtaining unprocessed logs, which has contributed to the loss of timber industry jobs in the Pacific Northwest. Thus, many believe that exporting logs is the economic and moral equivalent of exporting U.S. jobs.

Mechanical degradation temperature of waste storage materials

Description: Heat loading analysis of the Solid Waste Disposal Facility (SWDF) waste storage configurations show the containers may exceed 90{degrees}C without any radioactive decay heat contribution. Contamination containment is primarily controlled in TRU waste packaging by using multiple bag layers of polyvinyl chloride and polyethylene. Since literature values indicate that these thermoplastic materials can begin mechanical degradation at 66{degrees}C, there was concern that the containment layers could… more

Study of Pu consumption in Advanced Light Water Reactors. Evaluation of GE Advanced Boiling Water Reactor plants

Description: Timely disposal of the weapons plutonium is of paramount importance to permanently safeguarding this material. GE`s 1300 MWe Advanced Boiling Water Reactor (ABWR) has been designed to utilize fill] core loading of mixed uranium-plutonium oxide fuel. Because of its large core size, a single ABWR reactor is capable of disposing 100 metric tons of plutonium within 15 years of project inception in the spiking mode. The same amount of material could be disposed of in 25 years after the start of the … more
