This will depend on many factors including the types of vehicles being filled, when they’re filled, how much fuel they need at each fill, the size limitation of the site, and the budget available, to name but a few.
An important issue is whether the station is for private use or for public refuelling as this may determine the types of dispensers and the point of sale equipment as well as the filling method (fast fill or time fill).
Fast Fill is where the car is filled from a stored volume of gas that has previously been filled by the compressor. The speed of fill is comparable to petrol or diesel and is typically found on public forecourts.
This is the only suitable method of refuelling public cars or where cash payment is made, i.e. the quantity of gas put into each automobile has to be known.
Time Fill is where the vehicle is filled straight from the compressor without the need for extensive storage cylinders at the refuelling station. This method requires the vehicles to be parked up for some length of time, typically overnight, and is therefore suited to depot based refuelling like buses. The quantity of fuel dispensed into each vehicle isn’t easily monitored and therefore this method cannot be used for public refuelling.
Electronic dispensers are the more sophisticated and have the ability to be pressure and temperature compensated, that is they have the ability to dispense a very accurate quantity of gas no matter what the operation or ambient weather conditions.
They also have the advantage of being “locked out” until some form of access card or point of sale equipment authorises it to be used.
Electronic dispensers tend to be fully automatic in operation and are always found on public forecourts and massive CNG stations.
The quantity of dispensers required will very much depend on the base parameters of the station.
This includes the number of cars using it per hour, the size of each fill, the type of vehicle using the station (cars, buses etc.) and the size of the refuelling station (compressor, storage, gas pressure)
If for example it takes 5 minutes to fill a car (including time to attach and detach the filling hose) then you can only fill a maximum of 12 vehicles per hour on each hose.
If you have 500 cars filling at a refuelling station then you will be need two hoses, i.e. 12 automobiles per hour for 24 hours = 288 cars per hose (1224) per day, therefore need two hoses.
In relation to the compressor and associated equipment, CompAir has invested heavily in ensuring its equipment is as safe as practically possible.
All CompAir stations have many safety protection devices including:
Inlet Solenoid Valves
Inlet Non-Return Valves
Inlet Pulsation Vessels
High & Low Pressure Switches
Gas Inlet Filter
Auto Drain Solenoid Valves
Blow Down Vessel Return lines
Gas Tight Oil Filler
Vent Stack Manifold
Compressor Delivery Non-Return Valve
Starter Control Panel Pressure Switch
Exd Marshalling Box
IS Marshalling Box
Acoustic and explosion proof enclosures
Answer:
Compressed Natural Gas (cng) is filled into a special tank with an adapter that you go to a typical Gas Dealer (everywhere) and they can fill it up for you no problem. Some cars/trucks have removable tanks that you can fill up as well at the same places.
Answer:
You go to a place, and have them change the empty cylinder of one with the gas in it. Or go to a an exchange place and pick up a cylinder and install it your self.
Answer:
u hve to find cng filling station/find someone who does the refilling in its tank in ur city as its risky to be done by urself as its smell content of leakage is quite minimal & also a improper implantation would result in wastage
Answer:
