AbstractAbstract
[en] Using encapsulated Co-60, a distillation column in chemical industry was scanned to precisely identify the location and the type of malfunction, which was deteriorating the quality of product resulting in economic loss. On this investigation, flooding was observed in some area of trays and the column was shut down to remove the cause of it. Two more scans were carried out during and after the repair work to get more details on each tray. It has been verified that column scanning provides crucial information about operating column for troubleshooting and maintenance. Radioisotope tracers, La-140 and Kr-78, were used to investigate the flow dynamics of solid phase and gas phase inside a regenerated fluidized catalytic cracker unit in petroleum industry. As the RFCC creates more valuable product from low-grade heavy oil, its condition directly affects to the economic benefits. No other techniques but radiotracer technique can show the flow distribution of each phase in the sections where reaction and separation take place

AbstractAbstract
[en] This study describes and interprets petrochemical variation of the matrix (excluding fractures and large gas cavities) of the Topopah Spring Member of the Paintbrush Tuff. This tuff includes the candidate host rock for a high-level nuclear waste repository at Yucca Mountain on the Nevada Test Site. Cored hole USW G-4, near the site of a potential exploratory shaft at Yucca Mountain, penetrated 359.4 m (1179 ft) of the member within the unsaturated zone. This study shows that petrographic textures and chemistry of the matrix vary systematically within recognizable lithologic subunits related to crystallization (cooling) zones, welding (compaction) zones, and compositional zones (rhyolite versus quartz latite). The methods used for this study include petrographic modal thin section analysis using an automated counter and electron microprobe analysis of the groundmass. Distinctive textural categories are defined, and they can be ranked from finest to coarsest as vitrophyre (glass), cryptocrystalline groundmass, spherulites, granophyre, lithic fragments, and phenocrysts. The two main groundmass compositions are also defined: rhyolite high silica) and quartz latite. The value of these petrochemical studies lies in providing microscopic criteria for recognizing the zonal subunits where they may have greatly limited exposure, as in mined drifts and in core from horizontal drill holes. For example, the lower nonlithophysal zone can be distinguished microscopically from the middle nonlithophysal zone by (1) degree of compaction, (2) amount of quartz, and (3) amount of lithic fragments. The variability between these textural categories should also be considered in designing physical and chemical tests of the Topopah Spring

AbstractAbstract
[en] Petroleum is the major energy source that supplies 35% of the total power all over the world. And the petrochemical industry generates a 120 times higher value from naphtha, and in cooperates new technology in order to keep its business prosperous. These large plant industries require in-service diagnosis technology for an optimal and efficient operation and maintenance. Since diagnosis information obtained from an on-line plant can be used for a correct operation and maintenance workplan in the case of a deteriorated product quality as well as a mechanical abnormality, this technology can contribute to a huge cost benefit and a product competitiveness. The gigantic plants equipped with heavy materials can hardly be evaluated with conventional techniques due to their harsh environment of a high temperature and a pressure. Radiation and radioisotope application technology has been studied to meet the demand of the industry, but has yet to be developed further. In spite of its usefulness, the strategic support is not enough to carry out the research activities on advanced industrial testing technology using radioisotopes. It is of importance to secure a national competitiveness by intensifying the support for the newly emerging technologies such as an industrial gamma tomography and a process visualization and validation incorporated with a CFD

AbstractAbstract
[en] This invention concerns gamma ray spectroscopy logging, and particularly a process and device for studying the lithology of terrestrial formations by gamma ray spectroscopy brought about by a neutron bombardment. This process comprises the following stages: irradiate a formation by neutrons of sufficient energy to trigger off in it the 26Mg(n,γ)27Mg and 48Ca(n,γ)49Ca activation reactions, measure the activity level of the gamma rays resulting from the decay of the 27Mg and 49Ca by using a high resolution gamma ray detector, and combine the 27Mg and 49Ca determinations to provide an indication on the lithology of the formation
