How Does an LNG Mobile Refueling Station Work?
The use of liquefied natural gas (LNG) as a fuel is increasing around the world due to its low greenhouse gas emissions and relatively low cost compared to diesel. To make this fuel more accessible, mobile refueling stations have been developed to meet the fueling needs of both on-road and off-road vehicles. In this article, we'll discuss how an LNG mobile refueling station works.
The basic components of an LNG mobile refueling station include an LNG storage tank, a pump and vaporizer unit, a dispensing unit, and controls for safety and operation. Let's look at how each component works.
LNG Storage Tank .
The LNG storage tank is the primary component of the mobile refueling station. It is a highly insulated tank that can store up to 13,000 gallons of LNG. The tank is double-walled to prevent any leaks, and it has a pressure-relief valve to ensure that it doesn't over-pressurize. The tank is also equipped with a pressure gauge that tells the operator how much LNG is left in the tank.
Pump and Vaporizer Unit.
The pump and vaporizer unit is responsible for transferring the LNG from the storage tank to the dispensing unit. This component uses a pump to move the LNG through a vaporizer, which heats the liquid to convert it into gas. The pump also increases the pressure of the LNG to ensure that it can be dispensed at the correct pressure.
Dispensing Unit .
The dispensing unit is where the LNG is dispensed into the fuel tanks of vehicles. It consists of a hose, nozzle, and meter that measure the amount of LNG dispensed. The nozzle locks onto the fuel tank to prevent any leaks, and a venting system ensures that any excess gas is safely vented away from the vehicle.
Controls for Safety and Operation.
The controls for safety and operation are essential to ensure that the refueling station is used safely and efficiently. These controls include an emergency shut-off button, pressure gauges, and temperature gauges, which monitor the pressure and temperature of the LNG at all times.
Dialogue-Style Content.
"Wow, that's a lot of equipment!" Jane said as she looked at the LNG mobile refueling station being set up outside her office. "How does it all work?".
"It's pretty straightforward," replied the technician. "The LNG is stored in the tank and then transferred to the dispensing unit, where it's dispensed into the vehicle's fuel tank. The pump and vaporizer unit ensure that the LNG is at the right pressure and temperature.".
"That's pretty cool," Jane said. "How long does it take to fill up a vehicle?".
"It depends on the size of the tank," the technician explained. "But typically, it takes about the same amount of time as filling up with diesel.".
