Embodiment Construction
[0012] A receiving system and processing method for liquefied natural gas provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0013] In general, the present invention provides a multi-functional LNG receiving system. On the basis of receiving terminal storage and regasification functions, the system adds LNG transfer function, CNG service function and CNG delivery Features. Among them, the transshipment function of LNG can be water transportation or land transportation, and the water transportation of LNG can be bulk transportation or container transportation; the land transportation of LNG is transported in the form of containers. CNG can be delivered by water or land, and both water and land transportation of CNG are shipped in the form of containers.
[0014] Such as figure 1 As shown, the multi-functional liquefied natural gas receiving system of the present application includes: LNG ...

The invention provides a liquefied natural gas (LNG) receiving system, which comprises an LNG transport ship, an LNG transport ship anchoring dock, an LNG unloading system, an LNG storage system, an LNG regasification system and an LNG transport system, wherein the LNG transport ship carries LNG to travel to and fro between the receiving system and an LNG source; the LNG transport ship anchoring dock is provided with a pipeline and used for unloading the LNG from the LNG transport ship through the LNG unloading system; the LNG unloading system is used for unloading the LNG from the transport ship to the LNG storage system through a low-temperature pipeline arranged on a terminal marine facility and the LNG transport system; the LNG is transported to the regasification system, an LNG bulk transshipping system and an LNG container transshipping system from the LNG storage system through the LNG transport system; the gasified natural gas is exported through the LNG regasification system; and the LNG transport system is arranged between the LNG storage system and the LNG receiving terminal marine facility as well as between the regasification system and the LNG storage system, and is used for transporting the liquefied gas or the regasified gas inbetween.
Description
technical field [0001] The present invention relates to liquefied natural gas (LNG) storage and transportation technology, more specifically, the present invention relates to a liquefied natural gas receiving system and processing method. Background technique [0002] For the use of natural gas in places other than the gas source, three methods are usually used for transportation. The first is to send natural gas from the gas source to the user through the natural gas pipeline. The second is to liquefy natural gas at the gas source to form liquefied natural gas (LNG) to the place of use by water or land, and then send it to the user after regasification at the place of use. The third is to compress natural gas to form compressed natural gas (CNG) and transport it to the user by water or land. [0003] At present, long-distance water transportation is usually transported in the form of liquefied natural gas. Combined with the actual situation in our country, the eastern co...
