Comparison among LNG,CNG and L-CNG Filling Stations

There are three modes with different technological processes and equipment,including LNG,CNG and L-CNG,in natural gas filling stations.The equipment,construction cost,operation cost and safety of the three kinds of gas filling stations are compared.LNG filling station is superior to CNG filling station in construction cost and safety,and L-CNG filling station is one between the both.Under the condition of gas filling capacity of 10 000 m3/d,the annual total operation cost of LNG filling station is higher than that of CNG filling station only if the purchasing price of LNG is higher than that of CNG by 0.151 yuan/m3.It is suggested that LNG filling station should be set up first under permissible conditions.
