Application of a modular gas regulating unit (MGRU)

Modular gas regulating units are designed:

  • to decrease a high and medium natural gas pressure to the required range and its automatic maintenance within the set limits according to GOST 5542;
  • to purify gas from mechanical impurities;
  • to measure gas flow for commercial and process needs;
  • automatically to shut off of gas supply during emergency increase and decrease of the outlet pressure.

MGRU are applied for gas distribution and gas consumption systems in industrial and public utility spheres.

Working conditions:

The modular gas regulating units (MGRU) are designed for operation in areas with moderate (U in Russian, N in English) and moderately cold (UHL in Russian and NF in English) climate as well in areas with cold climate (HL in Russian, F in English). Climatic type of MGRU is chosen depending on a construction area according to the requirements of GOST 15150–69. MGRU can withstand 8.0-magnitude earthquake according to the Construction regulation SNiP P-7-81. Designed snow load (200kgf/m2) complies with the requirements of the 5th territorial region; wind load (85kgf/m2) conforms the 7th territorial region according to SNiP 2.01.07–85.

The modular gas regulating unit consists of:

The structure of the modular gas regulating units depends on a technical design assignment and on the basis of this assignment MGRU can include: a gas purification skid, a gas flow measuring skid, a gas reducing skid, a heating skid (a boiler house), instrumentation and automation cabinet with ACS TP and telemetry.

The design of the gas purification skid includes filters with 100% or 50% backup (depending on the customer's requirements) as well there is an automatic switching from working filters to backup and automatic discharge of condensate into a condensate collection tank.

The gas pressure reducing skid includes working and backup reducing lines with 100% or 50% backup). As well there is an automatic switching from main gas pressure reducing lines to a backup one.пожарно-охранной сигнализацией, производитель БатысМунайГазЖабдыктары

MGRU is equipped with a gas detection system, a fire and security alarm system and APCS of MGRU.

САУ ТП ПГБ, производитель БатысМунайГазЖабдыктарыAPCS of MGRU based on SIEMENS automatically controls isolation valves and monitors correct operation of all process equipment. Protective algorithms of APCS ensure a high operational safety. Thus, MGRU is insulated from gas supply if pressure deviates from the set range, if there is any fire signal or if the concentration of combustible gases in the compartments is exceeded. Process parameters and alarm signals are remotely transmitted to the control room (via a leased line, a telephone line, GSM, etc.). ACS has a backup power designed for 3 hours of autonomous operation (according to the specification it can be up to 3 days).

Process equipment of MGRU is placed in a block container that protects it from influence of climatic factors and unauthorized access. The MGRU block-container consists of an all-welded metal frame, mounted on a rigid frame of sections. Incombustible mineral wool plates on the basis of basalt fiber are used as a heat keeping material; hydro and vapor insulation is also provided. The interior decoration of the walls and ceiling are made with a painted corrugated sheet metal C8 that is fixed to the frame through a magnesium oxide wallboard (magnesia board) (non-combustible material) to minimize so called “cold bridges”. Exterior finish: walls from metal siding, roofs from corrugated sheet metal MP-20. The block container is divided into two rooms by a sealed separated wall: the first room is for process equipment and the second room is for a heating system and an automated process control system (APCS MGRU). Each room has a separate entrance.

Our technical specialists will handle your application as soon as possible and provide their expert assistance in selecting the configuration of equipment and components.

BatysMunaiGazZhabdyktary, LLP has experience in developing MGRU of various modifications: with two or more outputs, with different regulators (medium and low pressure) and with large gas capacities (up to 500,000 Nm3/h or more).
