The virtual pipeline system allows LNG to be transported to non-pipeline connected areas, virtual pipeline system that enables LNG to be distributed to industries all across the country, without any disruption in supplies.
Greenville has a fleet of 300 cryogenic LNG trucks which will take LNG from its production unit or refilling stations to customer locations all over the country.
Greenville LNG is produced at our liquefaction plant in Rumuji, Rivers state. At our production plant, LNG is stored at or near atmospheric pressure, in insulated, double-walled tanks of 250m3 capacity each; our LNG storage tanks are full containment tanks. Our LNG is distributed to our customers, refueling stations and kept pressurized in specially designed double-walled and vacuum insulated storage tanks in either a vertical or horizontal position.
Greenville LNG road transport tanks trucks/trailers (this includes both tanker trucks and tank trailers) are filled at our LNG terminals. LNG can be transferred to the trailer or tanker truck from our storage terminals using two methods: by differential pressure (receiving trailer has lower pressure than storage vessel) or by means of a transfer pump. Generally, flexible stainless-steel hoses are used; however, in some cases, hard piped arms with swivel connections or hoses made of multi-layer composite material are used. Greenville LNG provide controlled access or fleet/card lock to help ensure that the personnel performing the transfer operation are properly trained on safe practices.
Economy:
The use of a natural gas vehicle (NGV) provides a very significant saving at two levels. According to data from the Portuguese Natural Gas Vehicle Association (APVGN), on the basis of an equivalent liter, natural gas costs about 70% less than diesel. On the other hand, a NGV consume a clean-burning fuel, which reduces the maintenance requirements as regards the oil exchanges or spark plugs, for example.
Environment:
Natural gas is the cleanest of the fossil fuels currently used as alternative. NGVs emissions of carbon dioxide are about 20% lower, the non-methane hydrocarbon emissions are 80% lower, and the nitrogen oxides are 40% less than gasoline-powered vehicles. Furthermore, NGVs emit significantly lower quantities of greenhouse gases and toxins. Plus, natural gas is not corrosive and does not contaminate the soil.
Security:
NGVs are as safe as vehicles that run on conventional fuels. The excellent safety record of NGVs is due, mainly, to the structural integrity of the fuel system and the physical qualities of natural gas. The NGVs safety requirements powered are quite demanding, which ensures the user unquestionable levels of security.
Abundance:
World reserves of natural gas are almost the double of the oil, according to official information available on the site Association for the Study of Peak Oil and Gas. Another strong argument of this energy source is that it can be achieved through systems pullers applied in dumps and landfills, extracting bio-methane (also known as biogas). The bio-methane can be converted to natural gas and compressed, to be used as a power source for vehicles. Thus, it appears as a renewable energy.
Greenville LNG have Mobile Repair Trucks, in the case of a break down. LNG must be kept in containers which function like thermos bottles – they keep the cold in and the heat out, for it to remain in a liquid state. As heat transfer occurs naturally over time, which results in the increase in temperature and pressure of the stored LNG, some of the LNG vaporizes, thus as a safety measure, pressure release devices (PRDs) are installed to ensure that the increase in pressure does not result in rupture of the tank, or a leak from any component. Should the pressure exceed a defined level, a PRD will open and release gas through an outlet pipe to the atmosphere. Once the tank pressure has dropped back to normal operating pressure, the PRD will reset. However, due to the robust tank design (double walls and vacuum insulated) and the extremely low temperature of the LNG, it is possible for the tanks to remain at a safe pressure for many days, or even weeks, without a need for the PRD to open.
Greenville LNG Mobile Repair Trucks services are open 24/7* 365 days.
Greenville LNG Mobile Refuel Trucks services are open 24/7* 365 days.
Passenger cars, light-duty trucks, heavy-duty vehicles, delivery vans, forklifts, ice cleaners, shuttle buses, school and transit buses can all run smoothly on natural gas.
