FIELD: heating.
SUBSTANCE: invention refers to continuous gas conditioning method. Method of continuous gas conditioning, preferably natural gas, prior to its pumping to pipeline, and namely to network pipeline designed for delivery to consumers, in which the gas under pressure is taken from the storage and expanded, and before or after expansion, it is heated to certain temperature; at that, partial flow of gas removed from the storage is mixed with oxygen, and formed combustible gas is catalytically burnt and gas supplied from the storage is heated due to waste heat energy. Partial flow of exit gases is separated from flow of hot gases emitted during catalytic combustion and supplied together with cold combustible gas to the first unit (8), and combustible gas in the first unit (8) is mixed with supplied partial flow of exit gases and heated; and thus, heated mixture of exit gases and combustible gas from the first unit (8) is discharged to the second unit (15), in which it is subject to catalytic combustion, the heat after which is used to heat the natural gas supplied from the storage to be conditioned up to the required temperature. Natural gas supplied from the storage is expanded immediately prior to its being pumped to the second unit (15). Expanded natural gas is separated into partial flows, from which at least one partial flow is pumped around reactor (14) of the second unit (15) and at least the other partial flow is supplied to mixing chamber (17) of the second unit (15); at that, partial flow of heated natural gas, which leaves reactor (14), is supplied to mixing chamber (17). Gas flow leaving mixing chamber (17) is supplied with separator (18) means. In order to maintain the condensate separation to the gas flow, absorbent, for example triethylene glycol, is pumped to fix water vapour.
EFFECT: invention allows providing safe conditioning mode.
