At present, there are economic, ecological and ener-gy efficiency problems in dealing with the oil indus-try. We have tried to solve this problem through a solar thermal application. Thus, parabolic-trough solar plant utilization in the oil industry is a relative-ly new application in the area of solar energy usage. In Azerbaijan (Baki), such an application has firstly been realized in the crude oil treatment process by us. We must mention that a solar energy application has a great advantage for the oil industry to be eco-nomical with fossil fuels partly, to improve safety measures and ecology, and to also reduce addition-al financial expenses. Besides the ecological and economical facets, the obtained results from the experiments, which have been carried out in the Absheron Peninsula (Baki), are useful from an ener-gy efficiency point of view in the field of solar ther-mal applications by using parabolic troughs. These experimental results are significant on account of economic, energy efficient and ecological advan-tages.

In this work, influence of annealing temperature on the electrical properties of unmodified bentonite has been investigated. It is concluded that, by the increase of annealing temperature, the values of permittivity and conductivity are decreased, but the electric resistance and the density of the bentonite are increased. It is also shown that the basic reason for this is the presence of water molecules and alkaline oxides such as Na2O, K2O in bentonite.
