95106390 Integrated energy optlmlzatlon model for a cogeneratlon based energy aupply aystem In the process Industry Arva$~~an,A. et al., Electrical Power & Energy Systems, 1995, 17, (4), Most of the continuous process industries generate electricity by cogeneration using the heat energy required for the process. Electricity is also purchased from external sources such as the grid and generated by internal sources such as diesel gensets. This leads to the de&Ion problem of determining the economically optimum energy-mix during short and long term oeriods. Also it is imoortant to evaluate the various technologies that can ‘unprove the energy sipply system. The paper resents a mixe;l integer (O1) linear programming model to tackle the ago ve decision problem.and presents a case study on the application of the model. It is shown that the model provides the methods for determining the optimal strategies that _ minim&e the overall cost of energy for the process industry. Integrated gaslflcetlon combined cycle In Italy ss/O6391 Taberelli, D. Pet Review, Oct. 1995, 49, (585), 456-457. The author discusses the three Integrated Gasification_ *Combined Cycle (IGCC) projects under study in Italy, where each is at a different stage. All are planned to be constructed in refineries and to use heavy fuel oil as feedstock. Italy has suddenly become the cutting-edge of advanced technology in refineries as far as residue disposal is concerned. The projects represent an attempt by the refineries to enter into the fastest growing and most profitable energy business of the future - electricity. 95/06392 Micro-cogeneretlon: Gas sector’s latest weapon Raaijen, W. Gas (Nerherlands), Sep. 1995, ll:, (9), 28-33. (In Flemish) Low-energy natural gas equipment is an interestmg trump up the gas sector’s sleeve. After all, energy saving is a major social objective. And an objective that in many cases can be served by replacing electrical apparatus with natural gas equipment. The brightest prospect that companies such as Gasunie and Gastec have, however, is even more ambitious. It is about micro-generation, or the power plant at home. In addition to producing hot water for central heating-and tapping purposes, electricity is-generated on site. Within a few years the first micro-cogeneration systems will be put on the market. _ 95106393

Y. and George, 0. Desalination, 1995, 101, (2), 169-176. The pa er discusses the use of heat of compression from the gas compressor anB waste heat from the diesel compressor drive engine in a tripleeffect feed forward evaporator as a means of concentrating saline produced water to facilitate its disposal. The saline water, trapped in deeply buried coal seams, must be contmuously pumped from coal-bed natural gas wells, so that the gas can desorb from the coal amd make its way to the wellbore. Approximately 47% of the energy in the fuel supplied to the compressor drive engine was utilized by the evaporator for the base case. When the approach temperature in all evaporator heat exchangers was specified to be 5.55 K (as a limiting case), the eva orator system could handle a produced water-to-produced gas ratio of 1.4s kg/m’.
