Mining of methane from deposits subaquatic gas hydrates using OTEС

The article proposes to using Ocean Thermal Energy Conversion (OTEC) increase the energy efficiency mining of methane from deposits subaquatic gas hydrates on hydrate cycle (GHET), that will allow not spend 10-15% extracted for power supply a gas-producing complex (GPC). circuit-technological solution GPC is described, according which carbon dioxide introduced into layer extract hydrates. To improve kinetics process replacement with in hydrates, it proposed do recirculation part CO2. scheme and gas-hydrate energy-technological installation GHET are given, operates OTEC generates together electricity GPC, fresh water cold. Based method this paper, comparative thermodynamic analysis installations Black Sea conditions was performed. by Anderson cycles shown specific useful work obtained cycle, approximately 3 times more, energetic 1.5 more.
