METHOD TO DELIVER NATURAL GAS TO CONSUMER Russian patent published in 2013 - IPC F17D1/65 F17D1/04 F17D1/16 C10L3/10 C07C9/04 C07C9/02 

FIELD: power engineering.

SUBSTANCE: method includes production of gas hydrates, their transportation to a consumer, decomposition of a gas hydrate with production of gas, and is characterised by the fact that the gas hydrate is produced in the form of a water-hydrate pulp with content of gas hydrate particles of around 50% of its volume. At the same time the process to produce gas hydrates is carried out under thermodynamic parameters that correspond to formation of gas hydrate, with heat removal from a mixture of natural gas and water by a water and ice pulp, preferably, with particle size of not more than 10 mcm, with content of ice particles of around 50% of the water and ice pump volume, which are evenly distributed in the reactor volume, transportation of the gas and hydrate pulp is carried out in tight, heat-insulated cargo premises of a vehicle, under thermodynamic parameters that exclude decomposition of the gas hydrate, besides, decomposition of the gas and hydrate pulp with gas removal. Upon completion of its transportation, the pressure in the cargo premise of the vehicle is reduced down to the atmospheric one. At the same time the water and ice pulp produced in process of decomposition of the gas and hydrate pulp is returned, with preservation of its temperature, to the place of production of gas hydrates, where it is used repeatedly in production of the water and ice pulp suitable for production of the gas hydrate.

EFFECT: usage of this invention will make it possible to reduce power, capital and current costs for production of a gas hydrate, and to reduce material intensity of equipment necessary for implementation of the method.
