A system and method for liquefied natural gas gasification based on solar cycle power generation

Abstract

The invention provides a liquefied natural gas gasification system and method based on solar power cycle power generation. The gasification system includes a heat collection and heat storage unit, a power generation unit and a natural gas gasification unit, and the heat collection heat storage unit and the power generation unit pass through the first A heat exchanger is connected to the power generation unit, the power generation unit is connected to the gasification unit through the third heat exchanger and the fourth heat exchanger, and the natural gas gasification unit is connected to the gasification unit through the second heat exchanger The heat collection and heat storage units are connected. In the gasification system of the invention, the collected solar energy is used in stages, the high-temperature heat transfer working medium first generates electricity through the organic Rankine cycle system, and the waste heat is used for the gasification of jet liquefied natural gas. Gasification, which improves the gasification rate of liquefied natural gas and realizes the saving of non-renewable energy.

Description

technical field [0001] The invention relates to the field of gasification of liquefied natural gas, in particular to a system and method for gasifying liquefied natural gas based on solar cycle power generation. Background technique [0002] With the rapid development of the global economy and society, people's demand for energy is increasing. Under the premise that the requirements for environmental improvement are getting higher and higher, how to improve the utilization rate of renewable energy and further improve the utilization rate and saving degree of non-renewable energy is becoming more and more important. [0003] The gasification process of liquefied natural gas needs to consume a lot of energy. The existing gasification methods of liquefied natural gas generally have the disadvantages of limited adjustable heating load, great impact on the environment, complex system, and the need to burn a large amount of natural gas for gasification itself. The operation is in...

[0003] The gasification process of liquefied natural gas needs to consume a lot of energy. The existing gasification methods of liquefied natural gas generally have the disadvantages of limited adjustable heating load, great impact on the environment, complex system, and the need to burn a large amount of natural gas for gasification itself. Inconvenient to operate and not conducive to saving energy

In addition, in my country, solar energy is a kind of long-lasting renewable energy that is ubiquitous and has a very large developable reserve. It is still relatively seldom used in the field of natural gas gasification, and there is almost no use of concentrated solar energy and injection methods for natural gas gasification. cases and studies
