Abstract

The invention belongs to the technical field of liquefied natural gas (LNG) storage and gasification, and relates to a floating storage and gasification device which constantly supplies natural gas fuel to port natural gas users and power stations. The floating storage and gasification device comprises at least one medium-pressure region storage tank arranged on a ship body, a low-pressure region buffer tank, an immersed pump box and an LNG gasification device, wherein the low-pressure region buffer tank, the immersed pump box and the LNG gasification device are sequentially connected with the medium-pressure region storage tanks. Limited to industrial standards, liquid outlets of the low-cost medium-pressure region storage tanks with outer layers made of a carbon steel material are formed in the tops of tank bodies, continuous flow of LNG is achieved through the working air pressure difference between the medium-pressure region storage tanks and the low-pressure buffer tank, and then continuous supply of the high-pressure LNG is achieved. The floating LNG storage and gasification device has the advantages of being convenient to dock, low in manufacturing cost, capable of achieving continuous gas supplying, easy to control and the like.

Description

technical field [0001] The invention belongs to the technical field of LNG storage, transportation and gasification, and in particular relates to a floating storage and gasification device for continuously and uninterruptedly providing natural gas fuel for port natural gas users and power plants, including the control system and control system of the storage and gasification device method. Background technique [0002] LNG is the abbreviation of Liquefied Natural Gas, and its main component is methane. LNG is condensed into a liquid by cooling the gaseous natural gas to -162°C under normal pressure. After the natural gas is liquefied, it can greatly save storage and transportation space, and has the characteristics of large calorific value and high performance. [0003] LNG is a clean and efficient energy source. Many countries have listed LNG as the preferred fuel. The proportion of natural gas in energy supply is increasing rapidly. LNG will become the next hot energy com...
