COMPLEX FOR NATURAL GAS SUPPLY TO CONSUMER Russian patent published in 2014 - IPC F17D1/65 F17D1/04 C10L3/10 F17D1/16 C07C9/04 C07C9/02 

FIELD: transport.

SUBSTANCE: invention relates to supply of natural gas to consumer at its conversion into gas hydrate. Gas conversion means comprises reactor connected with gas and water sources, means to cool the mix of water and gas, means to maintain reactor pressure not lower than equilibrium pressure required for hydrate formation and means to discharge gas hydrate into carrier. The latter should have cargo compartments that can maintain thermodynamic equilibrium to rule out gas hydrate dissociation and means to decompose gas hydrate for gas production. Complex reactor can form gas hydrate pulp and is composed by the tank designed to sustain pressure over 1 MPa and to keep up temperature at the level of 0.2°C. For this, means to cool the mix of gas and water comprises the vacuum ice generator. The latter is composed of heat-insulated tank communicated with sea water source and vacuum outlet of turbocompressor. Note here that ice generator outlet is connected with separator of ice from brine, separator ice outlet being connected with ice mixer and sweet water. Note here that natural gas source is connected with reactor gas inlet and ice generator turbocompressor gas turbine. Reactor second inlet is connected via ice-bearing pulp duct with ice-bearing pulp accumulator composed of heat-insulated tank. Note here reactor hydrate outlet is connected via first pulp duct with hydrate-bearing pulp accumulator. Reactor water outlet is connected with ice mixer and sweet water. Note also that said outlet of ice mixer and sweet water is connected via second ice-bearing pulp duct with ice-bearing pulp accumulator inlet. Besides, gas hydrate discharge means comprise pulp pump and gate arranged at ice-bearing pulp accumulator discharge pipe to be connected with carrier cargo compartment intake pipe. Note also that carrier cargo compartment can be connected with discharge compressor intake pipe, discharge compressor outlet is connected with gas-holder.

EFFECT: lower costs, power savings.
