GAS DISTRIBUTION STATIONS "SARATOV"

 

Gas distribution stations are intended to supply gas taken off from gas mains and branches under working pressure up to 8 MPa to settlements, industrial and agricultural facilities and individual gas consumers located in areas with a moderate climate.

Gas distribution stations (GDS) "Saratov" are produced in seven modifications with the capacity from 100 to 50000 m3/h and are used for supplying the natural gas to separate users from gas mains with pressure from 1.2 to 7.5 MPa.

The designed outlet pressure for users - 0.3 – 1.2 MPa and for own needs - 0.002 – 0.005 MPa is automatically kept with the given accuracy.

The stations "Saratov" work in the open air in districts with the seismicity equal to seismic force 8 and at the environment temperature from –40 to +50 of °С and the relative humidity (95±3)% at 35 °С.

GRS "Saratov" work in automatic regime and guarantee the carrying-out of the following MAIN FUNCTIONS:

• the gas cleaning from the condensed moisture and mechanical impurities;
• the automatic discharge of sediment in drainage tank and it’s recovery by means of overpressing;
• the gas heating before pressure reduction;
• reduction of high gas pressure up to the designed low pressure and keeping this low pressure with the given accuracy when gas input pressure or gas flow rate change;
• gas odorization in proportion to flow rate before user feeding;
• measurement of gas flow rate with everyday data registration for a long period of time;
• automatic control of work station regimes;
• generation of emergency and warning signals on the operator’s or dispatcher’s desk during the work regime breaking.

TECHNICAL SOLUTIONS:

• GDS is delived on the erection site in the form of complete tuned up equipment in strict accordance with questionnaire requirements. The cover walls and the roof are made of the warmth-keeping material in the form of "sandwich-panels".
• The gas flow rate measurement in GDS with everyday registration is accomplished by complexes "SuperFlow-II", "HyperFlow-3Pm" or by the counter type SG with the electronic corrector EK-88/K.
• In the discharge condensate system there is a gas separator, which gives the opportunity to use a tank instead of the high pressure reservoir, the tank dumping is carried out by means of overpressing.
• The block of gas pressure reduction consists of two lines (work + reserve), in which two regulators are installed in consecutive order, one regulator is "protective". These pressure regulators with the elastic gate are characterized by the high accuracy of pressure keeping and low noise level.
• The gas heating before reduction is accomplished by the heater with the interval heat-carrying agent or with the flame heater of direct action.
• The automatic control system of GDS is placed in a floor box and provides the work conditions control, generation of emergency and warning signals on the dispatcher’s or operator’s desk.
• The presence of the second exit with "domestic" gas pressure of 2–5 kPa permits to supply gas to users situated near the GDS without installation of separate GRP.
• GDS "Saratov-5; 10; 20; 30; 50" are completed with odorization blocks, providing automatic gas odorization in proportion to flow rate without discharge of odorant vapours in the atmosphere

AUTOMATIC GAS PRESSURE REDUCING STATION, TYPE RP-10

 

Automatic gas pressure reducing stations are used for supplying gas to specific industrial installations and other gas consumers.

Automatic gas pressure reducing stations can be operated in areas with mild and cold climate at ambient temperatures from -40 °C to +50 °C. The station is equipped with a gas heater.

The main functions:

- gas pressure reducing up to the designed level;
- pressure control;
- protection of reducing elements from the overpressure;
- supporting of the pressure gas nominal value in the designed limits.

RP has two independent lines, when one line gets out of order the other may be automatically switched on.

Automatic gas pressure reducing stations, type RP-10S, RP-10S-1 and RP-10SA, are delivered with an original heater maintaining constant temperature (45 - 60°C) in the gas pressure reducing cabinet during the ambient temperature variation from -40 °C to +50 °C, thus preventing formation of hydrates in gas pressure reducing.

 

There are 2 ways to deliver gas to gas consumption facilities:

1. Both lines are united in a single collector and through a single pipeline are connected with a gas consuming facility; in this case, gas flow rate varies from 1 m3/h to 90 m3/h (56 m3/h).

2. Each output line through a separate gas pipeline is independently connected with its gas consumer; in this case, gas flow rate varies from 1 m3/h to 45 m3/h (28 m3/h). Outlet pressure in each line can vary within the certified range, in accordance to the technical characteristic chart.

The heat-insulated jacket in vandal-proof modification, the rational inside arrangement, the possibility of optimization of electric power supply from 150 to 1500 W, the application (on order) of voltage converter of supply 220 V of alternating current allow to create the ideal conditions for the uninterrupted work of GTG-150, radioelectronic equipment, communication devices and so on.

The main functions of the Autonomous Power Supplies:

• uninterrupted electric power supply to users;
• providing of the given temperature inside the block-container (AIPT);
• automatic power transfer in an emergency on the pipeline to reserve supply from accumulators before the arrival of emergency brigade;
• providing the comfort working conditions for the attending personnel during maintenance;

• transmission of emergency signals to the telemechanics system: fire signals, signals about the unforeseen door opening and gas presence;
• accommodation of the equipment in wall and floor variant in protected conditions.

The high reliability, the work without service, the absence of movable parts, the safety maintenance, the protective functions make the working expenses on gas and oil mains service considerably decrease.

CATALYTIC THERMOELECTRICAL POWER INSTALLATIONS

 

The catalytic thermoelectric power installations (KATEU) with electric capacity of 180 to 1000 W are intended for use as the safe autonomous sources of the electric supply for linear telemechanics and automatics, communication system and cathodic protection of gas mains without service in any climatic zones, and also for domestic light and heating of industry objects.

Construction features:

KATEU (basic complete set) is a block-box of vandal-proof modification, inside which are installed:

- catalytic thermoelectric generators KATEG-90/24;
- voltage stabilization block BSN;
- switching and information boards;
- lighting system;
- fire alarm system;
- warning system about the unauthorized penetration inside the block-box.

KATEU are supplied with the reducing block RP-10.

 

The main work characteristic of the catalytic thermoelectric generators KATEG-90/24 as a part of KATEU, is the absence of the open fire. The heat temperature for thermoelectric modules is reached by means of the chemical oxidation reaction (catalysis) of gas-air mixture, which is going on in the closed space of the catalytic chamber of special construction, and the chemical reaction temperature of catalysis is considerably lower than the temperature of gas ignition.

KATEG consists of a case 1, in which the injector 2 is placed, through this injector the gas-air mixture is entering the catalytic chamber 3. The catalytic chamber is filled with the catalyst 4, where the catalysis process is going on. The extracted heat is supplied to thermoelectric batteries 5. The heat abstract is accomplished by radiators 6. KATEG has the equipment compartment 7, where the needed equipment is installed (the stabilizer, the ammeter, the voltmeter and so on).

KATEG use the natural gas out of gas mains and condensed gas (propane-butane) at the environment temperature of –40 to +50 °С.

The main features:

- the absence of the open fire and high reliability;
- simple actuation and service;
- long-life performance and absence of capital outlays during mounting and putting into operation.

POLARIZED DRAINAGE, TYPE PD-ZAM

Polarized drainage, type PD-ZAM, is intended for protection of underground metal structures (oil and gas pipelines, communications facilities, foundations and etc.) from corrosion caused by stray currents.

To protect facilities, stray currents are led away from metal structures to a railroad circuit or a negative bus bar of the tram power substation or electrified railway generating stray currents.
