FAQs

What is CNG?

Compressed Natural Gas (CNG) is a fossil fuel substitute for gasoline (petrol), diesel, or propane fuel. Although its combustion does produce greenhouse gases, it is a more environmentally clean alternative to those fuels, and it is much safer than other fuels in the event of a spill (natural gas is lighter than air, and disperses quickly when released).

CNG is made by compressing natural gas (which is mainly composed of methane [CH4]), to less than 1% of its volume at standard atmospheric pressure. It is stored and distributed in hard containers at a normal pressure of 200-248 bar (2900-3600 psi), usually in cylindrical or spherical shapes.

CNG is used in traditional gasoline internal combustion engine cars that have been converted into bi-fuel vehicles (gasoline/CNG). Natural gas vehicles are increasingly used in Europe and South America due to rising gasoline prices. In response to high fuel prices and environmental concerns, CNG is starting to be used also in tuk-tuks and pickup trucks, transit and school buses, and trains.

CNG's volumetric energy density is estimated to be 42% of LNG's (because it is not liquefied), and 25% of diesel's.

What is a Conventional station?

The natural gas in the pipeline is usually at a pressure between 1 up to 100 bar. The GETPack compress the gas up to 250 bar and send it to the Storage. The Storage is made by cylinders and its scope is to guarantee refueling stations have permanent pressure of gas ready to be sold trough the Dispenser.

The Dispensers are the devices that supply vehicles with CNG fast and safely. The Dispenser can be one or double hoses, to fill one or two vehicles simultaneously.

All these process are monitored by the Control Panel. The Control Panel monitors alarms, control the pressure and the gas discharge from the compressor to the Storage cylinders and the use of Dispensers, reporting the filling data to the station computer.

The Conventional station in some case can be used to refill trailers, in this case instead of a normal Dispenser, it will be used a filling post.

What is a Mother station?

The natural gas in the pipeline is usual at a pressure between 1 up to 100 bar. The GETPack, compress the gas, increasing the pressure up to 200/250 bar, according to the standards in each country.

Once compressed, the gas is stored in the trailer cylinders to be delivered to the daughter stations or, in case of an industrial use, to the final client.

This process is regulated by a control panel that control the pressure, per each stage of the gas compression, the gas discharge from the compressor to the cylinders. All this process can be monitored also by a remote pc, by using GET proactive maintenance program.

What is a Daughter station?

The Daughter station in a CNG station that receive the gas not from the pipeline but from a trailer. The CNG in the trailer is at a pressure of 200/250 bar, according to the standards in each country.

The GETPACK compress the gas up to 250 bar and send it to the Storage. The Storage is made by cylinders and its scope is to guarantee refueling stations have permanent pressure of gas ready to be sold through the dispenser.

The Dispensers are the devices that supply vehicles with CNG fast and safely. The Dispenser can be one or double hoses, to fill one or two vehicles simultaneously.

All these process are monitored by the Control Panel. The Control Panel monitors alarms, control the pressure and the gas discharge from the compressor to the storage cylinders and the use of Dispensers, reporting the filling data to the station computer.

What is a Mobile station?

The Mobile station is a daughter station assembled on a trailer, generally used to bring CNG in areas far from the pipeline or as feasibility study instrument for \'daughter station projects\' in special areas.

The mobile station receive the gas not from the pipeline but from a trailer. The CNG in the trailer is at a pressure of 200/250 bar, according to the standards in each country.

The GETPACK compress the gas up to 200 bar and send it to the Dispensers. The Storage is made by cylinders and its scope is to guarantee mobile stations have permanent pressure of gas ready to be sold through the Dispenser.

The Dispensers are the devices that supply vehicles with CNG fast and safely. The Dispenser can be one or double hoses, to fill one or two vehicles simultaneously.

All these process are monitored by the Control Panel. The Control Panel monitors alarms, control the pressure and the gas discharge from the compressor to the storage cylinders and the use of Dispensers, reporting the filling data to the station computer.

The mobile station can be assembled in different configuration. Depending on the client request, it can be with a big storage or without, in case a power generator is needed.

What is NGV?

A natural gas vehicle or NGV is an alternative fuel vehicle that uses compressed natural gas (CNG) as a clean alternative to other automobile fuels. Natural gas can be used in all classes of vehicles - motorcycles, cars, vans, trucks, buses, lift trucks, locomotives, even ships and ferries. Natural gas can be used either by converting an existing gasoline or diesel engine, or by using a purpose built natural gas engine.

Benefits of natural gas vehicles include:

• Reduced particulate and NOx (Nitrogen Oxides) emissions
• Reduced greenhouse gas emissions
• Widespread availability of natural gas
• Lower cost
• Can be derived from renewable sources (biogas)
• Technically proven
• Available now
• Can be used in all vehicle classes
• Minimal processing or refining requirements
• Safer than most liquid fuels
• Can be refueled at home or workplace
• Noise reductions of as much as 50%
• Reduced engine wear
• and more...

With these benefits, its easy to see why natural gas vehicle (NGV) numbers have more than doubled in the last 5 years alone. There are almost 9.6 million NGVs worldwide and the International Association for Natural Gas Vehicles (IANGV) is projecting that this will increase at least ten-fold, to 50 million vehicles by 2020.
