Аннотация: Phase transitions of petroleum waxes and of oil well wax deposits in aliphatic and mixed hydrocarbon solvents were studied by differential scanning calorimetry. n-Undecane and gas condensate were used as aliphatic solvents straightly and as binary and ternary mixtures with cyclohexane and p-xylene. The temperature at which the petroleum and oil well waxes start to crystallize is lower in binary aliphatic-aromatic systems than in aliphatic solvents. The degree of crystallinity of waxes is maximal in aliphatic solvents and minimal in aliphatic-aromatic and aliphatic-naphthene-aromatic systems, which is in agreement with the morphological features of the samples studied. The results obtained led to a conclusion that it is appropriate to use gas condensate compounded with aromatic concentrates for removing wax deposits, in particular, at low stratum temperatures. © 2015 Pleiades Publishing, Ltd.
