Lopushans'kyj A. Rational maintenance of gathering facilities and transportation systems of products of gas condensate fields taking into account ecological safety.

The Thesis is devoted to the investigation of internal corrosive process regularity in the pipelines of gathering facilities and transportation system of the products from drilling wells of gas condensate fields; the influence of this process on mechanical characteristics of pipeline material; corrosive fistulization and areal formation of soil pollution. To increase the hydraulic effectiveness of gas con-densate pipelines and decrease harmful influence of system on environment there have been offered to conduct periodical displacement of liquid phase from the pipelines by ball separator. A number of experimental research have been conducted to investigate the influence of movement velocity of ball separators with different weight and diameter on the effectiveness of liquid phase displacement from pipelines.
