CNG Storage Tank to Minimize the Filling Time of CNG into a Storage Tank

Now a day, most of the vehicles are running on CNG storage system. The natural gas is also economical and efficient. In CNG storage system, sometime it happens that if there is a low pressure at the fuel station and high pressure is required in storage tank. Thus, it will consume more time from fuel station to tank. So, i will going to design the storage tank as per the requirement which can fill storage tank with low pressure too with cascade connection system. At compressed natural gas refilling station, CNG must be stored in storage system in order to make utilization and usefulness of the refilling station more efficient. There are two types of storage system buffer and cascade. In this research there are different material used for CNG tank and by this analysis for finding which material is best suitable for better designing of CNG tank. In designing i will reduce the pressure inside storage tank for that i will going to make partition in CNG storage tank so that the pressure inside the tank will reduce and also install the control valves system for maintaining required pressure. This will help to increase the fueling rate as well as reduce the time required for filling process. Also i will use the cascade cylinder for refuelling the high compressed gas in small cylinder without use of compressor.
