AbstractAbstract
[en] The disposition of petroleum coke remains a problem for modern high conversion refineries. Market uncertainty and the price for coke can prevent the implementation of otherwise attractive projects. The commercially proven Texaco Gasification Process remains an excellent option for clean, cost effective coke disposition as demonstrated by the new coke gasification units coming on-line and under design. Previous papers, have discussed the coke market and general economics of coke gasification. This paper updates the current market situation and economics, and provide more details on cost and performance based on recent studies for commercial plants

AbstractAbstract
[en] Environment protection measures at underground coal gasification (UCG) plants were considered. They are subdivided into two groups: measures related to underground and overland complexes. In the underground complex the main problem involves gas leakage control. In the overland complex special attention is paid to gas purification from dust and tar in gas wells directly and to isolation of ammonia and phenols from complex gas condensate, and hydrogen sulfide - from the gas. UCG is a potential source of a new type of energy product of ecologically clean enterprises

AbstractAbstract
[en] The new method of intra cycle pyrogasification of low-grade power fuels at thermal power plants is considered. The advantages of the technique are shown as compared with the conventional gasification. The products, which are produced at the first stage of the process can be partially used as commercial output (e.g. for producting synthetic liquid motor fuel) which allows to reduce or completely reimburse the expenses of TPP fuel preparation. 5 refs., 2 figs

AbstractAbstract
[en] The Texaco Gasification Power Systems integrate Texaco's proprietary gasification technology with proven power generation and energy recovery schemes for efficient and environmentally superior fuel utilization. Texaco's commercial experience on gasification spans a period of over 40 years. During this time, the Texaco Gasification Process has been used primarily to manufacture synthesis gas for chemical applications in one hundred commercial installations worldwide. Power generation using the Texaco Gasification Power Systems (TGPS) concept has been successfully demonstrated at the Texaco-sponsored Cool Water Coal Gasification Program in California. The environmental superiority of this technology was demonstrated by the consistent performance of Cool Water in exceeding the strict emission standards of the state of California. Currently, several TGPS projects are under evaluation worldwide for power generation in the range of 90MW to 1300MW

AbstractAbstract
[en] In order to investigate the potential of Al-SBA-16 Mesoporous Nano material as a candidate for radiopharmaceutical vehicles, the studies of kinetics, thermodynamic, and in vitro stability of Iodide adsorption onto the nano material have been carried out. The adsorption study was conducted at different temperature, time, and iodide concentration and observed with spectrophotometric techniques. The isotherm adsorption was fitted with Langmuir and Freundlich model and the thermodynamic parameters were determined at temperatures of 293 K, 301 K, 308 K, and 313 K. Moreover, the adsorption kinetics was analyzed in terms of pseudo first order model for AlSBA-16 Mesoporous Nanomaterial and Iodide and pseudo second order in overall reaction. The activation energy was determined by using Arrhenius equation, meanwhile, the in vitro stability testing was conducted in phosphate buffer saline at pH variation for 5.5 to 7.0, and at temperature variation for 20 oC to 45 oC and at testing time variation for 6 to 48 hours. The result indicate that the adsorption obeys the Langmuir isotherm model and has a tendency to be chemical adsorption with a value of DH was -116.641 kJ/mol and the nature of spontaneous reactions. The adsorption process followed the pseudo-first-order model and the apparent activation energy was 41.26 kJ/mol. In the present research work, the in vitro stability data were evaluated using P-Value and the theory of Hypothesis Testing or Fisher's significance test. The result of hypothesis testing show that, the adsorption of iodide onto Al-SBA-16 Mesoporous Nanomaterial were highly stable under the experimental conditions adopted. (author)

AbstractAbstract
[en] Fly ash powders are prone to agglomerate due to its properties that easily absorbed moisture even in normal atmosphere. The present study relates to granulation process to reduce particles agglomeration and produce free flowing powders. The fly ash was dispersed in aqueous medium at pH 10.5 in the presence of 1 wt% sodium metasilicate and 2 wt% multifunctional molecules such as glucose and glycerol. The mixture was centrifugally separated dried at 70 degree C for 48 hours and then granulated by rotation. The granules were heat-treated at 400 degree C for 1 hour and separated by sieving using 32 and 45 μm sieve trays. The morphology of fly ash granules was observed using scanning electron microscope (SEM) shows that the granulation significantly reduces the particle agglomeration and produces a homogeneous size of powders. The flow properties of the powder are remarkably improved by the granulation process. (Author)

AbstractAbstract
[en] From the Proceedings of the Lombard Milan Section of the Italian Thermotechnical Association and ANIMA, Italian Boiler Constructors Union, November, 199I, Convention, 'Coal and heavy hydrocarbons gasification for electric power production', separate abstracts were prepared for 15 papers. The topics mainly dealt with the design and energy efficiency aspects, as well as, the cost-environmental benefits to be had by Italian industry with the use of high efficiency, low polluting integrated gasification combined-cycle (IGCC) power plants equipped to run on Italy's Sulcis (Sardinia) brown coal. Technology assessments were prepared for a variety of commercially promising gasification processes, e.g., the high-temperature Winkler (HTW) Rheinbraun, Texaco, and Fauser-Montecatini processes

AbstractAbstract
[en] The transportation sector in the United States is 95 per cent dependent on oil, which is the only primary fuel that is being imported to the country in great quantities. It has been proposed that energy independence may come by supplying electric power with renewable energy sources. It was also suggested that the best solution for future transportation may be to develop electrified guideways that would provide energy to automatically convey personal cars and driverless freight through the roadways. Advantages include zero vehicle emissions, greater safety and decreased road congestion. This paper examined the option of using heavy oil for power generation instead of the current expensive refining practices designed to produce liquid transportation fuels from heavy oil. It compared coal gasification with heavy oil for power generation. The cost to consumers and environmental impacts were considered. The comparison of conventional versus electrified transportation options was based on on a well-to-mine-to-wheels cycle. It was shown that electrified transportation is attractive from a cost, environmental and energy security perspective. If the United States were to import Canadian heavy oil only for transportation, the consumer cost will increase by approximately 25 per cent based on 2003 data. If the United States were to transform transportation from conventional to electrified transportation, the cost of using Canadian heavy oil will be less, even including carbon dioxide capture. It was concluded that all primary fuel sources would seek new equilibrium prices that may affect comparisons between heavy oil and coal. 14 refs., 4 tabs., 10 figs
