✦ Synopsis
02 Liquid fuels (sources, properties, recovev) to difficulties in analysing the recovered material but also in analysing the original oil in place. Moreover, the incompatibility of crude oil constituents with each other is a continuing issue and the occurrence of suspended organic solids during recovery (especially thermal) reduces the efficiency of a variety of processes. More detailed knowledge of the composition and reactivity of petroleum will help in understanding the means by which models can be applied to understanding recovery processes. The models that are proposed as a means of being applicable to the prediction of sediment (i.e. asphaltene, resin, wax) formation and deposition from petroleum due to changes in pressure, temperature and composition fall somewhat short in their structure. Further modelling needs to involve an understanding of the chemistry of these materials and reflect the more modern approach to the physico-chemical structure of petroleum in order to more correctly predict the onset of precipitation as well as the location and amount of the sediment deposition in the producing wells and in oiltransport pipelines. 99102424 Combustion heat of Karazharinskii coal, highviscosity petroleum and heavy petroleum residue Baikenov, M.
