Study On Feasibility Of Constructing LNG Subordinate Station

Among the energies, natural gas (briefly NG) is a safe and great one. 21th is the prime time of NG. Pipe transport is one of the most popular means of NG transport. Practice indicates: pipe transport is one of the most economical and efficient means of large scale of NG transport. However, in some districts pipe transport cannot forms a big NG supplying net, the extension in area of NG provision is limited, only can supply to the cities (towns) along the pipe~system, for the integrated factors of restriction, such as the rate of the people who use NG as their main fuel, the economic state and the extend of NG price of people's affording in a city (town). The provision system of Shenzhen will face this issue, future. Therefore, how to fulfill the demand of NG the normal or small cities (towns), will become another new study project.Besides pipe transport, NG also can be transported by other non-pipe means. One is to construct liquefied natural gas (briefly LNG) subordinate stations, through which NG can be potted and carried to small cites (towns) after being liquefied. The other is to construct compressed natural gas (briefly CNG) stations, through which NG can put into some special vessels then carried to small cities (towns) after being purified and compressed.LNG subordinate station is the station which NG can be transported to in small cites or subordinate cites and far away from the LNG plants in central cites, supply NG to the cites around them. LNG subordinate stations are always 30~200kms far from LNG plants and have a certain number of equipments for reservation. Through vehicles, ships etc, LNG can be transported to subordinate stations, then LNG can be supplied to all kinds of users after being evaporated.For the high cost and complicated crafts of the subordinate station's construction, it has different features compared to normal crafts. The LNG craft needs the assistance of many crucial techniques. The aims of this book is to speculate on the feasibility of subordinate station's construction after learning the properties, crafts of LNG and analyzing the crucial techniques.
