Mass Transfer Coefficients and Interfacial Area in a One Stage Pulse Column

Description: Over-all mass transfer coefficients were determined independently of the interfacial area by considering the operation of the pulse column to be a stage- wise process. The calculated coefficients describe only the operation of the pulse column for the free rise of organic droplets through a stage, since in the downstroke the aqueous phase passes through the organic phase in the form of rivulets preferentially wetting the plates. The driving force for transfer was based on the aqueous phase conc… more

Flow-induced vibration for light water reactors. Final progress report, July 1981-September 1981

Description: Flow-Induced Vibration for Light Water Reactors (FIV for LWRs) is a program designed to improve the FIV performance of light water reactors through the development of design criteria, analytical models for predicting behavior of components, and general scaling laws to improve the accuracy of reduced-scale tests, and through the identification of high FIV risk areas. The program is managed by the General Electric Nuclear Power Systems Engineering Department and has three major contributors: Gene… more

COMPARISONS OF CRYSTALLINE SILICOTITANATE AND RESORCINOL FORMALDEHYDE MEDIA FOR CESIUM REMOVAL BY IN-TANK COLUMN PROCESSING

Description: Chemical and thermal performance of crystalline silicotitanate (CST) and resorcinol-formaldehyde (RF) ion exchange media were predicted for column configurations designed for installation in high level waste tanks and intended for cesium removal from radioactive waste supernates. Modeling predictions for the processing of a known Savannah River Site tank waste composition were generated. In a two column configuration under presumed nominal operating conditions (432 gallon packed bed, 10 gpm liq… more

Small-amplitude periodic sloshing modes of a liquid in a vertical right circular cylinder with a concave spheroidal bottom

Description: The small-amplitude periodic sloshing modes of a liquid in a vertical right circular cylinder with a concave spheroidal bottom are calculated for the case in which there is not sufficient liquid to cover the bottom entirely. Equilibrium free surfaces of the liquid were calculated by the program CAPIL for the case in which the ratio of the minor and major semi-axes of the spheroidal bottom was 0.724. Perturbations about these surfaces were calculated by the program SLOSH. For the fill heights th… more

Expansion program 190 Building studies results

Description: It is the objective of this study to investigate preliminary expansion program requirements for process water, as supplied by 190 Building equipment; from the point of view of practical pumping, flywheel and pump suction head requirements. These requirements are to be determined at this time in such a form and accuracy as to be useful in refined estimating for budget study purposes. In order to obtain the objectives of this study at this time it has been decided to consider five different condi… more

Diffusionless fluid transport and routing using novel microfluidic devices.

Description: Microfluidic devices have been proposed for 'Lab-on-a-Chip' applications for nearly a decade. Despite the unquestionable promise of these devices to allow rapid, sensitive and portable biochemical analysis, few practical devices exist. It is often difficult to adapt current laboratory techniques to the microscale because bench-top methods use discrete liquid volumes, while most current microfluidic devices employ streams of liquid confined in a branching network of micron-scale channels. The go… more

PULSE COLUMN DESIGN

Description: A stagewise approach was used in a theoretical analysis of pulse columns. In the analysis the column was arbitrarily divided into discrete stages comprising that part of the column between two adjacent perforated plates. The operation of the pulse column was described mathematically using material balance equations, and a design method was derived which used two stage lines and two operating lines, one set for the pulse generator upstroke and one set for the downstroke. Assuming equilibrium con… more

Let-Down System Design for Homogeneous Reactors

Description: A study was made to determine the feasibility of designing a gas let- down system for homogeneous reactors, in which the pressure is taken through a fairly long tube rather than across a throttling valve. A schematic design of such a system is shown for the HRT in which the letdown stream passes through parallel tubes. Control is effected by the cutting in or out of tubes as is needed. Calculations indicate such a design is feasible. It is recommended that experimental work be done before the a… more

Advanced Stripper Gas Produced Water Remediation: Final Project Report

Description: Natural gas and oil production from stripper wells also produces water contaminated with hydrocarbons, and in most locations, salts and trace elements. The hydrocarbons are not generally present in concentrations that allow the operator to economically recover these liquids. Produced liquids, (Stripper Gas Water) which are predominantly water, present the operator with two options; purify the water to acceptable levels of contaminates, or pay for the disposal of the water. The project scope inv… more

Advanced Computational Model for Three-Phase Slurry Reactors Progress Report: November 2000

Description: In the first year of the project, solid-fluid mixture flows in ducts and passages at different angle of orientations were analyzed. The model predictions are compared with the experimental data and good agreement was found. Progress was also made in analyzing the gravity chute flows of solid-liquid mixtures. An Eulerian-Lagrangian formulation for analyzing three-phase slurry flows in a bubble column is being developed. The approach uses an Eulerian analysis of gas liquid flows in the bubble col… more

Productivity and injectivity of horizontal wells. Quarterly report, July 1--September 30, 1995

Description: During this quarter the authors have extended their earlier semi-analytical method for determining critical cresting rates in horizontal wells to the case of both water and gas cresting. The method and the procedure will be briefly described below. They also show the application of the method to an example problem and compare the results with direct numerical simulation.

Hydrodynamics of Gas-Liquid Counterflow Through Corrugated Parallel Plates

Description: Structured packings utilized in today's distillation packed towers consist of stacked units of many vertically oriented parallel corrugated plates. The V-shaped corrugations are oriented at a fixed angle with respect to the vertical direction, and the corrugation angle in adjacent plates are oriented in reverse direction. Points of contact, at the crests of the corrugations, between adjacent plates, form an unconsolidated porous medium with known topology. Modern structured packings have been g… more

Spiral Boiler Evaluation

Description: The results of the boiler optimization are as follows: Approximate boiler weight (filled with NaK and Hg under operating conditions), 102 lbs; tube length, 68 ft; tube ID, 0.587 in.; surface-to-volume ratio, 25 ft/sup -1/. The results of the boiler evaluation indicate that the centrifugal force produced by the spiraling effect is only 1/10 that produced by twisted strip turbulators. Published data indicate that twisted strips do not appreciably increase pressure drop for equivalent weight flow … more

Numerical simulation of coupled two-phase gas/liquid flow in an electric arc furnace

Description: The importance of an electric arc furnace (EAF) process in the production of steel has increased over the last decade. Currently, this process is used for 40 percent of the raw steel produced, and it accounts for the consumption of 20 TWhr of electrical energy. Furthermore, projections indicate that the EAF production process will account for 42 percent and 45 percent, respectively, of the total steel production in 1995 and 2000. The increasing cost of electricity, and the demand to produce hig… more

PRELIMINARY DESIGN OF SRE-PEP CORE III VARIABLE ORIFICE

Description: A single, wide-range variable orifice design is developed, which provides a maximum orifice flow area of 2.0 in./sup 2/ and a minimum oriflce flow area of 0.2 in./sup 2/ The design is based on an overall operating core DELTA P of 4.0 psi and provides for a sodium flow range of 2.45 to 10.0 lb/sec. Bypass leakage around the orifice is analyzed and accounted for in the design. It is shown that the use of piston rings is not necesary to reduce this leakage. The orifice plug profile is calculated f… more
