Abstract

The paper considers the process of formation of hydrate deposits on the walls of the pipeline, in the process of gas extraction from the ”dome-separator“, designed for emergency collection of hydrocarbons on the ocean floor. On the basis of the constructed mathematical model the influence of the kind of tube material on the deposition of gas hydrates is shown.

Article outline

Purpose: Study of the influence of the type of tube material for gas extraction on deposits of gas hydrates on its walls.

Methodology: The results were obtained using methods and approaches used in the field of mechanics of multiphase media. The simulation of the studied processes was performed in the Pascal programming environment.

Findings: On the basis of the constructed model the results of changing the thickness of hydrate deposits on the tube walls, as well as the velocity, temperature and gas pressure are obtained. It is shown that the use of rubber as a material for the manufacture of extraction pipes contributes to a longer preservation of the temperature of the gas in comparison with polyurethane, which in turn shifts the region of possible blockage of the pipeline to the surface of the ocean.

Originality: Reduction of heat removal from the extraction pipes by using various materials will help to prevent blockage of the pipes in the process of gas extraction from the ”dome-separator“.
