Heavy, brittle and very hard deposits built on the first row vanes have caused severe erosion of all the first stage blades of a gas turbine during operation with washed and treated heavy residual fuel oil. The high sulphur (3.5–4.0 wt.%) fuel oil consumed by the turbine is also high in vanadium (280–290 ppm) and asphaltene content. In the present work the results of an investigation on the physical and chemical characteristics of erosive ash deposits as a function of operation conditions and fuel oil characteristics are presented. The structure and chemistry of deposits were studied by chemical analysis, x-ray diffraction, microanalysis and scanning electron microscopy. It was confirmed that deposit friability is enhanced by its MgSO4 content and that its hardness depends on the amount of MgO present. It was also found a clear correlation between the gas inlet temperature and the size of the ash particles deposited, and on the degree of compactness and hardness of the deposit. The role of the unburned particles, unavoidable in the combustion of heavy fuel oils, is discussed in relation to their influence on the effectiveness of the magnesium inhibitor.

In the 1980s, Asian energy markets expanded at a rapid rate to meet the surge in demand from Japan, Korea, and Taiwan. This demand boom coincided with an increase in non-OPEC oil production in the region. As oil production stabilizes, demand looks set to rise sharply, this time in the new Newly Industrialized Countries of Southeast Asia, Thailand, Malaysia, and Indonesia. Natural gas will play a key role in this expansion of energy use and could start to lead rather than follow oil markets. The leading role of natural gas will be especially strong if gas starts to make inroads in the high and middle ends of the barrel with oxygenated gasoline and compressed natural gas for trucks. At the bottom of the barrel, natural gas could increasingly usurp the role of residual fuel oil for environmental reasons. At the same time, regional refiners could find that residual oil is their leading source of additional feed for the new process units currently under discussion or planning. The supply outlook for natural gas is increasingly fraught with uncertainties as more of the region's supplies must come from distant areas. In particular, LNG supplies from Malaysia and Indonesia will need to be replaced by the early part of the next century as rising domestic demand eats into the exportable gas production. New sources include China, Siberia, Sakhalin Island, Papua New Guinea, and Canada. There will be intense competition to supply the Northeast Asian markets as the gas production in Southeast Asia is increasingly used within ASEAN.

ABSTRACT A spill of about 7,400 gallons of No. 6 fuel oil into Lake Winona provided an unusual opportunity to observe the behavior of a residual fuel oil in a confined freshwater environment. Oil-laden condensate from Winona State University's heating plant entered Lake Winona via a storm sewer during the winter and, because of ice cover, went undetected until April 15, 1979. Because its density was almost the same as water, the oil caused unusual problems. Surface fractions were readily removed by standard measures, but cleanup was thwarted by heavier fractions which rose continually from the lake bottom and drifted throughout the lake. Scuba divers located a pool of heavy oil in a deep area near the storm sewer outlet and most of it was pumped into an on-shore reservoir. Globules of oil continued to rise from the lake bottom during the ensuing summer season, severely curtailing recreational use of the lake. The spill resulted in the deaths of waterfowl and it apparently stressed spawning sunfish sufficiently to trigger a kill by Flexibacter columnaris bacteria. The oil produced no taste problems in fish flesh. The cost of cleanup was almost $104,000, and a civil penalty of $3,500 was levied against the State of Minnesota. The entire episode was documented photographically.
