Assessment of the Potential for the Direct Application of Renewable Resources. Staff Issue Paper

Description: This issue paper is intended to take a general look at the direct application of renewable resources. The focus of the paper is to provide background information on what is currently known about these resources. The Council is interested in comments to supplement the information discussed in this paper. Perhaps more importantly, the Council is looking for recommendations on how to treat these resources in the next power plan. The Council is faced with at least two important questions related to this issue. First, should the Council attempt to develop detailed supply curves for these resources? Second, should programs be developed to encourage the acquisition of these resources? The direct application of renewable resources is generally defined as the use of a renewable resource such as solar, hydro, wind, geothermal and biomass for the direct reduction of electrical energy use by a consumer. While there have been previous staff analysis of these resources they have not been explicitly treated in previous power plans. Given the renewed emphasis on evaluating the environmental consequences of resource development, these relatively benign resources merit further analysis. This paper will provide the basis for treatment of direct application of renewable resources in the 1990 Power Plan. Most of these resources tend to be site specific and typically require large collection areas to capture a significant amount of energy. Because of high fixed installation costs, they also tend to be most cost effective with higher usage. These characteristics generally prevent widespread regional application and limit the size of any particular resource. Early programs designed to encourage these resources focused on individual end use applications. However, given the unique characteristics of these resources, it is likely that future programs will treat these resources as one option among several conservation measures applied to a given end use or ...

Enzymatic desulfurization of coal

Description: Our current efforts to develop clean coal technology emphasize the advantages of enzymatic desulfurization techniques and have specifically addressed the potential of using partially-purified extracellular microbial enzymes as well as commercially available enzymes. Our work is focused on the treatment of model'' organic sulfur compounds such as dibenzothiophene (DBT) and ethylphenylsulfide (EPS). Furthermore, we are designing experiments to facilitate the enzymatic process by means of a hydrated organic solvent matrix.

Establishment and maintenance of a coal sample bank and data base

Description: For each sample, one 30-gallon drum containing approximately 90 lb of coal at {minus}1/4 inch was designated for headspace oxygen analysis and coal quality monitoring at yearly intervals. Headspace oxygen analysis and retrieval of a 5-lb sample for coal analysis have begun. Headspace oxygen contents are shown in Table 1. Preparation and analysis of these samples for the second yearly quality evaluation is in progress. We have initiated a study of different means of storage in preventing sample deterioration and in maintaining an inert headspace atmosphere. The work was performed with support from the Penn State Cooperative Program in Coal Research. A run-of-mine sample of medium-volatile bituminous Lower Kittanning coal was collected as PSOC-1536 and promptly processed. Gieseler fluidity FSI, alkali extraction and preparation of petrographic pellets were accomplished within 32 hours of extraction of the coal from the mine face. Splits of the sample were sealed under argon in several container types.

Cross flow filter for AEPSC: TIDD slipstream HGCU project preliminary design package for Westinghouse cross flow filter system

Description: The Westinghouse ceramic cross-flow filter element is constructed of multiple layers of thin, porous ceramic plates that contain ribs to form gas flow channels. Consecutive layers of the ceramic plates are oriented such that the channels of alternating plates are at an angle of 90 degrees ( cross flow'') to each other. The current size of a ceramic cross flow filter element is 12 in. {times} 12 in. {times} 14 in. Both sides of the short channels (4 in.) are exposed to the particle-laden coal gas. One end of the long (12 in.) channels is sealed while the other end of the long channel is mounted to the clean gas plenum. The particle-laden coal gas flows through the roof and floor'' of the porous ceramic plates that comprise the short, dirty side'' channels. The gas flows through the porous plates to the long, clean side'' channels. The gas flows through the porous plates to the long, clean side'' channels and finally to the clean gas plenum. The dust cake on the dirty side'' channels is periodically removed by applying a high-pressure reverse pulse of dry, clean gas through the clean gas plenum. For the TIDD plant filter slipstream, air will be utilized for filter cleaning.

Proposed method of assembly for the BCD silicon strip vertex detector modules

Description: The BCD Silicon strip Vertex Detector is constructed of 10 identical central region modules and 18 similar forward region modules. This memo describes a method of assembling these modules from individual silicon wafers. Each wafer is fitted with associated front end electronics and cables and has been tested to insure that only good wafers reach the final assembly stage. 5 figs.

Enzymatic desulfurization of coal. Fourth quarterly report, March 16--June 15, 1989

Description: Our current efforts to develop clean coal technology emphasize the advantages of enzymatic desulfurization techniques and have specifically addressed the potential of using partially-purified extracellular microbial enzymes as well as commercially available enzymes. Our work is focused on the treatment of ``model`` organic sulfur compounds such as dibenzothiophene (DBT) and ethylphenylsulfide (EPS). Furthermore, we are designing experiments to facilitate the enzymatic process by means of a hydrated organic solvent matrix.
