METHOD OF PRODUCING GAS HYDRATES BY CONDENSATION OF NANOCLUSTERS Russian patent published in 2020 - IPC B01D7/02 B01D9/00 B82B3/00 B82Y40/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to production of gas hydrates for storage and transportation of gas in power engineering and gas industry. Hydrate formation is carried out in oncoming molecular beams of rarefied steam and gas, which enter the vacuum chamber through de Laval nozzles with reduction of temperature at nozzle outlet below 100 K and condensation to form crystalline ice nanoclusters of cubic diamond-like structure. Formation of clusters is accompanied by capture of gas molecules and formation of crystal hydrate phase. Content of gas in the crystallized condensate obtained at maximum achieved efficiency of the capture of gas molecules exceeds 50 wt %. Such content is achieved due to additional gas sorption during formation of crystalline condensate, which is a gas-saturated nanoporous medium containing a crystalline hydrate phase and crystalline ice.

EFFECT: method increases rate of formation of gas hydrate, reduces consumption of coolant required for cooling of substrate, increases productivity of producing gas hydrates.
