Automated Gas Odorization Unit (AGOU)

3689-002-55402257-2009 Specification
Use Permit No. РРС 00-35424

AGOU: Application

Automated Gas Odorization Unit (AGOU) is designed for a dosed supply and metering of the supplying odorant (ethyl mercaptan С2Н5SH) to natural gas flow before supplying it to a consumer in an automatic, semi-automatic or a manual mode.

The team of BatysMunaiGazZhabdyktary, LLP can assembly AGOU by using up-to-date technological standards of welding and protecting coating.

 

Operating Conditions

Automated Gas Odorization Unit (AGOU) is designed for operating in macroclimatic areas with moderate and moderate cold climate (NF), as well in areas with a cold climate (F).

 

AGOU includes the following main elements:

  1. supply tank
  2. odorant level metering and supply regulating package that includes:
    • level indicator
    • metering solenoid valve
    • filling solenoid valve
  3. level indicator with measuring scale
  4. level alarm SU-60
  5. gas ejector
  6. manometers
  7. gas pressure reducer
  8. binding fittings of odorant dosage package
  9. control unit BU-103.

AGOU has 3 modes: automatic, semi-automatic and manual.

Control is carried out from the control unit BU-103М (hereinafter is referred to as BU) that is installed in an operator’s room.

Odorizer control unit shows the following parameters:

  • current odorant flowrate, g/hr
  • current daily and previous daily odorant flowrate, kg/day
  • current monthly and previous monthly odorant flowrate, kg/month

One can enter data of actual odorant density manually.

BU provides a constant control for odorizer equipment condition and for any deviations from the specified value. If a such problem takes place BU generates a “Gas Odorizer Failure” signal that will be transferred to a high level. Signal type: dry contact.

 

 

AGOU: Automatic Mode

An automatic dosing mode through the metering solenoid valve (MSV) with automatic setting of the gas flow rate is carried out as follows: in automatic mode a signal about the gas flow rate can be transferred to the BU by three ways:

1. As a current signal with a range of 4 to 20 mA. A minimum GDS flowrate meets 4 mA of the BU setting, a nominal (maximum) value of the GDS flowrate is 20 mA of the BU setting. The values of the minimum and nominal flowrate of every particular GDS are recorded by a manufacturer in the BU memory.
2. As a direct value of gas flow through a MODBUS channel
3. As a pulse signal from the flowmeter with the setting of the gas flow rate corresponding to one pulse.

AGOU: Semi-Automatic Mode

A semi-automatic dosing mode is carried out through a metering solenoid valve with a manual setting of gas flow. In this mode, the gas flow rate to quantify the odorant dosing amount is set manually by an operator. The operator receives current gas flow rate (Qflow) from an external gas flow metering device and records this data in the BU ("Manual flow rate" function in the operating menu) using a keypad. A main signal forms a volumetric capacity and frequency of the solenoid metering valve actuation. A minimum interval of MSV switching on corresponds to the maximum GDS flowrate recorded in the memory of the BU./p>

AGOU: Manual Mode

A manual dosing mode is carried out through a regulating valve. This mode is a reserve one and it is applied in case of failure of automatic dosing system.




 

AGOU types:

Cabinet-type

 

  • Cabinet-type is divided to the following variants depending on climatic location area:
  • without heating;
  • with heating on the basis of water heating from an external source or electric heating. This unit is explosion-proof
