DEVICE TO PREPARE NATURAL GAS FOR TRANSPORTATION Russian patent published in 2013 - IPC F17D1/65 F17D1/04 C10L3/10 F17D1/16 C07C9/04 C07C9/02 

FIELD: power engineering.

SUBSTANCE: reactor is a reservoir designed for pressure of more than 1 MPa, heat-insulated to maintain temperature at 0.2°C, equipped with a facility of material mixing. At the same time a medium for cooling the mixture of water and gas is a finely dispersed water and ice pulp, for this purpose the device comprises a vacuum ice generator made in the form of a heat-insulated reservoir communicated with a source of sea water and a vacuum outlet of a turbocompressor, preferably made as capable of developing underpressure in the reservoir, which is equal in value to the pressure of the triple point of sea water. Besides, the outlet of the ice generator is communicated with a separator of ice from brine, the ice outlet of which is communicated with the mixer of ice and fresh water. In its turn the source of natural gas is communicated with the gas inlet of the reactor and the gas turbine of the turbocompressor made as capable of using energy of gases, natural gas combustion products, and the second inlet of the reactor, by means of a pulp line of the ice-containing pulp equipped with the first pulp pump is communicated with an accumulator of the ice-containing pulp made in the form of the heat-insulated reservoir. At the same time the hydrate outlet of the reactor is communicated by the pulp line of the hydrate-containing pulp with the accumulator of the hydrate-containing pulp made in the form of the heat-insulated reservoir, as capable of maintaining pressure not below the equilibrium one, excluding dissociation of the hydrate-containing material, with the possibility to discharge hydrate-containing pulp from it, besides, the water outlet of the reactor is communicated with the mixer of ice and fresh water, at the same time the outlet of the ice and fresh water mixer by means of the pulp line of ice-containing pulp equipped with the second pulp pump is communicated with the accumulator of ice-containing pulp.

EFFECT: reduced power inputs for production of hydrates and reduction of weight and dimension characteristics of a set of equipment required to produce hydrates.
