ON THE THEORY OF ACCUMULATION OF HYDROCARBONS IN A DOME USED TO ELIMINATE A TECHNOGENIC SPILL AT THE BOTTOM OF THE OCEAN

Consideration is given to the operation of a dome separator installed at the bottom of the World Ocean and intended to eliminate the effects of technogenic spill of hydrocarbons. It is assumed that oil and gas (methane) escape from the damaged well on the ocean fl oor. Under the conditions of stable existence of a hydrate, a hydration sheath is formed on the surface of methane bubbles. To collect the entering hydrocarbons, a dome from a soft polyurethane shell is installed above the spill site, inside which the hydrocarbons are accumulated. In the regime of steady-state operation of the dome, provision is made for pumping out of hydrocarbons for transportation and further utilization. In the work, temperature fi elds of the hydrocarbon layers accumulated in the dome are investigated.
