Proc. Annu. ISA Anal. Div. Symp., 2000, 33, 139-148. The measurement of Flash Point is an important safety parameter for refinery products. Online Refinery analysers are designed to correlate with ASTM laboratory methods. The purpose of this paper is to present an online method for the measurement of flash point of refinery products such as diesel, kerosene and fuel oil. The analyser used for the online flash point measurement is the ABB Analysis Model 4214 Flash Point Analyser. An important feature of the online analyser is the ability to adjust the heating rate of the sample to give agreement with the ASTM laboratory methods. The progress of the Flash Point Analyser analysis cycle can be observed on the LCD screen of the analyser. Other important design features are reliability and up time. Auto-validation with a standard sample ensures the reliability of the Flash Point Analyser. A maintenance concern for the operation of online Flash Point Analysers is the build up of coke on the sparking electrode. An anti-coking device is used in the flash point analyser to minimize coking problems and reduce maintenance requirements. 02/00190 Performance evaluation of heavy residual oils in the 500 MW IGCC plant Lee, S. et al. Hwahak Konghak, 1999, 37, (5), 775-781. (In Korean) As a way to evaluate the performance of the IGCC process with fuels from petroleum refineries, heating values of the raw gas as well as the plant efficiency were simulated by employing the static process simulation technique. Fuels chosen were visbreaker residue, butane asphalt and an asphalt from one Korean refinery. In order to verify the simulation technique, simulated results of a visbreaker residue were compared first with the actual demonstration plant data published from Shell Co. and then the simulation technique was applied to the cases of other fuels, butane asphalt and a Korean refinery asphalt. At the gasifier temperature of 13 OOO”,simulation results showed that the heating value of raw gas produced from residual oils was in the range of 2750-2800 kcal/m3 with the plant efficiency over 43%. The results exhibit the technical and economical viability of using heavy residual oils from petroleum refineries as successful fuels in IGCC power plants. 02/00191 Predictive heat model for Australian oil shale drying and retorting Berkovich, A.J. er al.

The exploitation of Australia’s oil shale reserves has been the subject of much research over several decades. The extraction of oil from shale is usually a thermal process and therefore oil shale processing is dominated by heat-transfer and thermal reactions. To fully develop any oil shale processing technology, knowledge of an oil shale’s thermodynamic properties is desirable. This paper presents a novel approach for the determination of an oil shale’s thermodynamic properties and subsequent development of a predictive heat model. This approach involves experimental determination of the thermodynamic properties of an oil shale’s individual components, in particular, the unique kerogen and clay minerals in Australian oil shale. The experimental data was then used to develop a predictive heat model for Australian oil shale based upon its kerogen and mineral, composition, and concentrations. The predictive heat model allows investigation of heat capacity, enthalpy, and total enthalpy for Australian oil shale during the process temperatures of drying and retorting. 02/00192 Problems of nonlinear fluid dynamics in industrial plants Terenzi. A. et al. Comvlex Flows Ind. Processes. 2000, 63-124. Edited by Fasano A. 1 Pipeline transportation of complex fluids generally involves an analysis of non-linear fluid dynamic phenomena, especially during transient phases. Snamprogettc has developed some models for predictions of pipeline flow characteristics relevant to both non-Newtonian solidliquid suspensions and compressible fluid transport. This chapter is divided into two parts. CWS (coal water slurry) Pipeline Flow: Homogeneous and Heterogeneous Conditions, describing the properties of coal-water slurries considered both in their homogeneous flow conditions (transient motion influenced by complex rheology behaviour) and with respect to prediction of unstable flow caused by settling processes. Transient Compressible Flow at High Mach Numbers: A Conservative Method for Pipeline Flow, describing the development of a code for simulation of transient phenomena associated with gas pipeline flow at high Mach numbers. 02/00193 Procedure for the separation of sulfur-free components from a motor fuel on board a motor vehicle Holder, E. ef al.

Rom. RO 108,575 (Cl. ClOC3/04), 30 Jun 1994, Appl. 9,301,420, 22 Ott 1993. 8. (In Romania) Oxidized bitumen is prepared from petroleum or coal processing residues containing minimum 5-S% asphaltenes and ignition temperature >295” by oxidizing with oxygen, air or a gas containing 20-150 L/ kg oxygen. The oxidation process takes place at 250-285” by bubbling the oxygen-containing gases through the molten residues. The oxidation promoters are selected from aluminium and iron chlorides, carbonates and/or sulphates of iron, zinc, copper and antimony, metallic sodium, silica gel impregnated with phosphoric acid or bismuth phosphomolybdate, oxides, sulphides or carbides of iron, copper, zinc, manganese, cobalt and titanium. The oxidation equipment consists of column-type reactors, heating devices and various accessories for oxidative gas inlet and outlets as well as other structural systems supporting the oxidation process of the petroleum or carbon processing residues. 02/00196 Process for the desulfurization of a hvdrocarbon stream Hansen, J.-H.B. et al.
