GAS DISTRIBUTION STATIONS "SARATOV-0.1; 1; 5; 10; 20; 50"
Gas distribution stations (GRS) "Saratov" are produced in six 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:
Zavod "Saratovgasavtomatika" develops and manufactures the main technological equipment, used in GDS, and constantly work at it’s improvoment.
JOINT HEAT CHAMBERS WITH ELECTRIC HEATING
The heat chambers provide the placement and protection of complicated measuring devices; flowmeters, moisture meters, pressure transducer, temperature transducer and other devices and also prevent the hydrate formation in impulse lines.
Construction features:
AUTONOMOUS POWER SUPPLIES
The autonomous power supplies AIP(T) are destined for supplying the electric power to users and work on gas and oil mains without standard sources of the electric power in remote districts. AIP are capable to work for a long time in any climatic zone without service.
Construction features:
The power unit completely mounted and tested in service conditions is a metal block-container inside which are installed:
- thermoelectric generators GTG-150;
- distributive board;
- information board;
- gas dosage block;
- voltage stabilization block;
- thermostatting system.
AIP are supplied with the reducing block RP-10.
The installation of thermoelectric generators GTG-150 in the warmth-keeping block-container made it possible to develop the autonomous power supplies AIPT, in which the extracted heat from fuel combustion is used as non-electric heating.
The original temperature control system, based on sampling regulation of air, heated in radiators GTG-150, and it’s mixing with the air, entering the container from the outside, allows to keep the given temperature inside the container from +10 to +45 0C with the environment temperature of –50 to +50 0C.
AIP is furnished with the control block for generators GTG-150, which serves: to limit the voltage, for automatic control of generators and also for remote command executions and output of discrete signals about generator’s work to the communication division.
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:
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.
AUTOMATIC REDUCING STATIONS RP-10
The automatic reducing station RP-10 are intended for the reducing of the high variable gas pressure (of 1.2 to 12.5 MPa) and supporting of the outlet pressure of 0.003; 0.05; 0.1; 0.15 MPa in accordance with the customer requirements and serve for gas feeding of the linear maintenance staff houses, industrial objects and other gas users.
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.
The reducing systems are supplied with the gas heater, which supports the constant temperature in the reducing box in the limits of 45-60 °С at the environment temperature changing from –40 to +50 °С, this excludes the hydrate formations and make it possible to use systems in districts with moderate climate and in districts with cold climate.
