The oil and gas sector widely uses standalone power supply systems whose source of electric power is gas turbine and gas engine generator plants.
The main fuel for these gas turbine and gas engine generator plants is treated natural gas, associated petroleum gas and derivative products resulting from its processing.
An automated gas distribution station is designed for supplying gas to populated areas, industrial enterprises and other consumers in specified volume and at specified pressure and with a required degree of treatment and odorization and quantity metering.
The automated gas distribution stations are used at the following installations:
- oil and gas field installations (for own needs);
- compressor station installations (for own needs);
- installations of small-, medium- and large-size populated areas, towns and cities;
- electric power stations;
- industrial enterprises.
Our company offers comprehensive solutions connected with the design and delivery of power systems, electric generation equipment, automated gas distribution systems and gas treatment units, including booster compressor stations of various types.
The automated gas distribution stations may be comprised of such processes as treatment, pressure reduction, prevention of hydrate formation (heating), odorization and gas flow measurement and, if required, qualitative characteristics control.
The automated gas distribution stations are manufactured in the form of separate functional units of the same kind or different kinds by putting together several functional units to form a common structural system (construction) in a single prefab modular building or permanent buildings in accordance with the design approved by the Customer.
In addition to its use at large installations in the energy sector, one of the methods of utilization of associated petroleum gas is its application as fuel for standalone/mobile gas turbine and gas engine generator plants providing remote oil and gas fields with inexpensive electricity and heat.
The direct use of associated petroleum gas as fuel gas for the standalone gas turbine and gas engine generator plants without due treatment causes power loss at the electricity generating plant and wear of its engines. To reach specified power it is necessary to fulfill a number of requirements.
In addition to the conventional requirements for removal of mechanical impurities and obtaining appropriate dew points (either water or hydrocarbon dew point temperature), there are other requirements relating to component composition and methane number of fuel gas.
Additional integrated fuel preparation techniques may be used in the utilization of associated petroleum gas, as distinct from preparation of natural gas at the automated gas distribution stations.
