【摘要】：随着我国对环境保护重视程度不断深化,LNG作为一种清洁、高效的能源越来越受到广大用户的青睐。在传统的气化工艺中,LNG气化产生的冷能直接被海水或空气带走,造成了能源的损失和浪费,同时由于大量的冷量被排到海水中或者室外,使得附近海域或站区环境受到严重的冷污染。为此如果能充分利用冷能,既可以保护环境又能够创造经济价值。本文以小型LNG气化站为前提,针对冷能利用的各种途径进行分析比较,比对之后总结出小型LNG气化站冷能发电的优势,并分析北京建设小型LNG气化站冷能发电的可行性。本文从五个方面进行阐述。首先对冷能应用方式进行分析及比较并得出结论;其次,对冷能发电进行技术比较与分析,主要包括冷能发电原理、发电新技术以及存在的问题等方面;第三,对LNG气化方式及气化器进行分析与选择;第四,分析了LNG气化站的规划设计及建站要点,主要包括建设规划要点、安全设计与主要附属设备等;第五,以某LNG气化站为例进行冷能发电可行性分析,主要包括分析气化站周边及用户情况,对其发电的经济性和可行性进行探讨。最后针对北京LNG气化站冷能发电的可行性提出建议和设想等。
[Abstract]:As our country pays more and more attention to environmental protection, LNG as a kind of clean and efficient energy is more and more favored by the majority of users.In the traditional gasification process, the cold energy generated by LNG gasification is carried away directly by sea water or air, which results in energy loss and waste. At the same time, a large amount of cold energy is discharged into seawater or outdoors.Make the environment of nearby sea area or station area suffer serious cold pollution.If we can make full use of cold energy, we can protect the environment and create economic value.On the premise of small LNG gasification station, this paper analyzes and compares the various ways of using cold energy, summarizes the advantages of cold energy generation in small LNG gasification station, and analyzes the feasibility of building a small LNG gasification station in Beijing for cold energy generation.This article carries on the elaboration from five aspects.First, the application of cold energy is analyzed and compared, and the conclusion is drawn. Secondly, the technology of cold energy generation is compared and analyzed, including the principle of cold energy generation, the new generation technology and the existing problems.Analysis and selection of LNG gasification mode and gasifier; fourth, analysis of the LNG gasification station planning design and station construction key points, mainly including construction planning points, safety design and main ancillary equipment, etc.Taking a LNG gasification station as an example, the feasibility analysis of cold energy generation is carried out, including the analysis of the peripheral and user situation of the gasification station, and the discussion on the economy and feasibility of generating electricity.Finally, the feasibility of cold energy generation at Beijing LNG Gasification Station is put forward.
