Development of a mathematical model of a packed column for benzene removal from salt solutions

Description: A mathematical model of a packed column was developed to describe the removal of benzene from radioactive salt solutions at the Savannah River Site. The model was developed from existing, generalized mass transfer correlations for randomly dumped packing, and the correlations were adapted for structured packing. Thermophysical data specific to the solutions of interest were incorporated into the model. Verification of the code was completed using operating data from stripping columns at other l… more

Thermal energy storage for power generation

Description: Studies strongly indicate that the United States will face widespread electrical power constraints in the 1990s, with most regions of the country experiencing capacity shortages by the year 2000. In many cases, the demand for increased power will occur during intermediate and peak demand periods. Much of this demand is expected to be met by oil- and natural gas-fired Brayton cycle turbines and combined-cycle plants. While natural gas is currently plentiful and reasonably priced, the availabilit… more

Modeling of coupled geochemical and transport processes: An overview

Description: Early coupled models associated with fluid flow and solute transport have been limited by assumed conditions of constant temperature, fully saturated fluid flow, and constant pore fluid velocity. Developments including coupling of chemical reactions to variable fields of temperature and fluid flow have generated new requirements for experimental data. As the capabilities of coupled models expand, needs are created for experimental data to be used for both input and validation. 25 refs.

Uncertainty in the power distribution for a fast reactor burnup cycle

Description: Demonstration that advanced reactor designs satisfy safety and performance goals requires the analysis of uncertainties in calculated reactor characteristics. Two of the important performance characteristics of advanced liquid metal reactors (LMR) are the burnup reactivity swing and the local power peaking factor. Previous work reported a study of the uncertainty in the burnup reactivity swing attributable to nuclear data uncertainties for a typical advanced LMR design. The results are reported… more

Modeling of Integrated Environmental Control Systems for Coal-Fired Power Plants Quarterly Report: June-September 1989

Description: The general goal of this research project is to enhance, and transfer to DOE, a new computer simulation model for analyzing the performance and cost of environmental control systems for coal-fired power plants. Systems utilizing pre-combustion, combustion, or post-combustion control methods, individually or in combination, may be considered. A unique capability of this model is the probabilistic representation of uncertainty in model input parameters. This stochastic simulation capability allow… more

A Broad View of Model Validation

Description: The safety assessment of a nuclear waste repository requires the use of models. Such models need to be validated to ensure, as much as possible, that they are a good representation of the actual processes occurring in the real system. In this paper we attempt to take a broad view by reviewing step by step the modeling process and bringing out the need to validating every step of this process. This model validation includes not only comparison of modeling results with data from selected experime… more

Development and process evaluation of improved Fischer-Tropsch slurry catalysts

Description: The objective of this contract is to develop a consistent technical data base on the use of iron-based catalysts in Fischer-Tropsch (FT) synthesis reactions. This data base will be developed to allow the unambiguous comparison of the performance of these catalysts with each other and with state-of-the-art iron catalyst compositions. Particular attention will be devoted to generating reproducible kinetic and selectivity data and to developing reproducible improved catalyst compositions.

Establishment and maintenance of a coal sample bank and data base

Description: Data from both instruments indicate that atmospheric oxygen is leaking into the primary and secondary containers. The methods and containers tested cannot maintain an inert atmosphere over the long term. The actual percentage of oxygen in the containers is thought to be influenced by several factors: (1) Flushing with argon by any method only displaces part (50 to 80%) of the atmospheric air present in the container after it is filled with coal. Because the atmosphere may not be homogeneous, an… more

Mechanisms governing fine particulate emissions from coal flames

Description: During this reporting period the global experiments were concluded. The final activities under these experiments involved measuring mineral content of coals as a function of coal particle size. The principal activities during this quarter involved the mechanistic experiments. Three baseline coals were cleaned and two of these sized. The ash from these various cuts were sampled from a bench scale reactor. The ash size distributions were compared to distributions predicted by the breakup model.
