FIELD: supply of gas to consumers of power-intensive plants and populated localities at preset flow rate, pressure and required odorizing. SUBSTANCE: gas distributing station consists of two units: technological unit and warning and monitoring unit, with air gap between them. Technological unit has the following components arranged in series: change-over devices, expansion chamber with swirler, condensate receiver, cleaning, flow measuring, preheating and pressure-reducing device and odorant reservoir. Warning and monitoring unit has boiler for preparation and supply of heat-transfer agent to gas preheating device. Odorizer of odorizing system is mounted on the outside of technological unit above outlet gas lines. Formation of hydrates is excluded not only by preheating gas before reducing its pressure but by the purpose of gas preheating device which is simultaneously heater of technological unit interior. Reservoir and odorizers of odorizing system are connected with gas consumer pipe lines by means of coupling pipe line, thus enhancing ecological safety of gas distributing station. EFFECT: high compactness of station, supply of gas to at least two consumers simultaneously, reduced length of piping; avoidance of hydrate formation and ecological safety. |
