【摘要】：近10余年來,隨著我國能源需求的不斷增強(qiáng),我國進(jìn)入了大型液化天然氣(Liquefied Natural Gas,LNG)接收站、調(diào)峰站、天然氣液化工廠的建設(shè)高峰期,經(jīng)過不斷實(shí)踐,我國LNG接收站在數(shù)量和規(guī)模方面都有較大提升。根據(jù)全球LNG產(chǎn)業(yè)發(fā)展近況及我國現(xiàn)階段天然氣供應(yīng)所面臨的一系列問題,我國接收站的建設(shè)采取的對(duì)策為:合理規(guī)劃格局,構(gòu)建沿海與陸地穩(wěn)定供應(yīng)的天然氣管網(wǎng);實(shí)施LNG供應(yīng)多元化,逐步優(yōu)化消費(fèi)結(jié)構(gòu);積極帶動(dòng)LNG相關(guān)產(chǎn)業(yè)的發(fā)展,實(shí)現(xiàn)天然氣產(chǎn)業(yè)市場(chǎng)化的長遠(yuǎn)發(fā)展目標(biāo)。蒸發(fā)氣(Boiled-off Gas,BOG)處理系統(tǒng)是接收站最復(fù)雜的部分,主要包括BOG壓縮機(jī)系統(tǒng)及火炬系統(tǒng)。BOG處理系統(tǒng)的平穩(wěn)運(yùn)行關(guān)系到整個(gè)接收站的安全穩(wěn)定性,其流量計(jì)算結(jié)果是BOG壓縮機(jī)、BOG入口緩沖罐、火炬系統(tǒng)、BOG總管等設(shè)備和管線的選型基礎(chǔ)。受卸船、管線漏熱、低壓泵散熱、體積置換和天然氣下游多種用戶用氣不均勻性等多種因素影響,接收站BOG產(chǎn)生量和LNG外輸量呈現(xiàn)實(shí)時(shí)的波動(dòng)特性。本文以某LNG接收站為基礎(chǔ),選取Pro II作為流程模擬工具,分析影響接收站BOG產(chǎn)生量的各個(gè)因素,將接收站的工藝流程劃分為卸船、外輸、裝車等基本單元,對(duì)BOG壓縮機(jī)及火炬系統(tǒng)的計(jì)算方法進(jìn)行了優(yōu)化,使之更接近接收站的實(shí)際運(yùn)行過程。并在8種不同工況下對(duì)各單元進(jìn)行計(jì)算與匯總,根據(jù)計(jì)算結(jié)果完成BOG壓縮機(jī)選型。本文的計(jì)算方法及選型結(jié)果可直接運(yùn)用于大型LNG接收站,為接收站關(guān)鍵設(shè)備的選型及BOG處理系統(tǒng)的優(yōu)化提供了理論依據(jù),具有較大工程實(shí)際意義。
[Abstract]:In the past 10 years, with the increasing energy demand in China, China has entered the large liquefied natural gas (LNG) receiving station and peak-shaving station. The construction peak of natural gas liquefaction plant has been practiced continuously. The number and scale of LNG receiving stations in China have been greatly improved. According to the recent development of global LNG industry and a series of problems faced by China's natural gas supply at the present stage. The countermeasures adopted in the construction of the receiving station in China are as follows: reasonable planning pattern, construction of natural gas pipeline network with stable supply of coastal and terrestrial gas; Implement LNG supply diversification and gradually optimize consumption structure; Promote the development of LNG related industries, realize the long-term development goal of natural gas industry marketization. Evaporation gas Boiled-off Gas. The bog) processing system is the most complex part of the receiving station. The smooth operation of the BOG compressor system and the torch system. Bog processing system is related to the safety and stability of the whole receiving station. The results of flow calculation are based on the selection of equipment and pipelines, such as BOG compressor inlet buffer tank, torch system bog pipe and so on. Because of the influence of volume displacement and gas inhomogeneity in downstream of natural gas, the output of BOG and the output of LNG at receiving station show real time fluctuation characteristics. This paper is based on a certain LNG receiving station. Pro II is selected as a process simulation tool to analyze the factors that affect the output of BOG in the receiving station. The process flow of the receiving station is divided into basic units such as unloading, outputting, loading and so on. The calculation method of BOG compressor and torch system is optimized to make it more close to the actual operation process of the receiving station, and each unit is calculated and summarized under 8 different working conditions. According to the calculation results, the selection of BOG compressor is completed. The calculation method and the selection result of this paper can be directly applied to large LNG receiving station. It provides a theoretical basis for the selection of the key equipment of the receiving station and the optimization of the BOG processing system, which is of great engineering significance.
