【正文】 is a huge waste of oil resources. Therefore, efforts to reduce evaporation loss, the construction of China39。在當(dāng)今國際原油資源日漸減少、需求量日益增大、價(jià)格持續(xù)飆升的環(huán)境下，蒸發(fā)造成的油品損耗量也逐漸明顯 .油品儲(chǔ)運(yùn)時(shí)的蒸發(fā)損耗占到整個(gè)儲(chǔ)運(yùn)損耗的 65％左右，這是石油資源的巨大 浪費(fèi)。 油品的蒸發(fā)損耗是指油品中的部分較輕的組份氣化，逸入大氣的過程。 關(guān)鍵詞 ：油氣損耗 浮頂罐 編程計(jì)算 《 油氣儲(chǔ)存技術(shù)與管理》課程設(shè)計(jì) ABSTRACT II ABSTRACT Oil depots storage and sales of crude oil and gasoline and other light oil contains a large number of light hydrocarbon ponents, the highly volatile, so inevitably there will be a part of the vaporization of liquid hydrocarbon ponent, in the form of oil and gas into the atmosphere environment, not only a waste of energy, but also cause environmental pollution, affect human body health. Evaporation loss of oil product refers to the ponent parts of the product is lighter gasification, the process of escape into the atmosphere. In today39。The programming calculation 《油氣儲(chǔ)存技術(shù)與管理》課程設(shè)計(jì) 目錄 III 目 錄 1 緒 論 ...................................................................................................................... 1 常用的計(jì)算方法 .............................................................................................. 1 2 油庫油氣蒸發(fā)損耗 .................................................................................................... 2 引起蒸發(fā)損耗的原因 ................................................................................... 2 溫度變化 ............................................................................................ 2 油罐上方空間的影響 ........................................................................ 2 油罐嚴(yán)密程度 .................................................................................... 2 大呼吸損耗 ........................................................................................ 2 小呼吸損失 ........................................................................................ 3 油品蒸發(fā)損耗的類型 ................................................................................... 3 油氣損耗的危害 ........................................................................................... 4 火災(zāi)危險(xiǎn)性 ........................................................................................ 4 造成能源浪費(fèi) .................................................................................... 5 油蒸氣污染環(huán)境 ................................................................................ 5 3 浮頂油罐的蒸發(fā)損耗量的計(jì)算方法 ...................................................................... 6 浮頂罐“小呼吸”損耗 ................................................................................. 6 浮頂罐“大呼
