i 淶 塣2070 80 豸 豸 ii abstract the recovery for oil vapor means in the process of operation, storage, sale and use the hydrocarbons volatilize then we eliminate the dissemination by gas gathering, processing in order to avoid accidents, air pollution and the loss of oil .the oil depot is the main place for oil delivering and receiving, so to work on the application of recovery technology is practical significant. since 20th century 70s, the developed industrial countries began to study the technology of recovery for oil vapor. china began to study the absorption method in accordance with the domestic situation at the time, developed a light diesel oil, gasoline for low-temperature absorbent recovery for oil vapor since 80s.in recent years, the continuous improvement of environmental awareness, our government has been efforts to protect environment. so far, the main parts of beijing and shanghai have been equipped with oil tanks of oil and gas recovery, but on the whole is not very high proportion. anyway, for the purpose of environmental protection, the technology for recovery of oil vapor and installation is the future trend and direction. in this text, i will calculate the evaporation of the oil tank in a depot of zhoushan. compare the efficiency of research and comparison of oil and gas recovery technology. in this text, there are four types of recovery technologies for oil vapor to be discussed, absorption method, adsorption method, condensation method and membrane separation method, and we will focus on the application of membrane separation method and introduce a complex of oil and gas recovery technology research and application. iii . i abstract ii 1. 1 2. . 2 2.1 . 2 2.2 3 3. 4 3.1 . 4 3.2 4 4. 14 4.1 15 4.2 15 4.3 15 4.4 . 16 5. . 16 5.1 17 5.2 . 21 5.3豸 . 24 5.4 28 . 28 29 1 淶 1 塣20 7080 豸 豸 1. 40 縡 档 60 80 桢 2 2. 2.1 2.1.1 gb110851989涨 1.71.00.71m31.7 l1.0 l 0.7 l 涨 1.49 200819229693161 1.32008 4.11 淶 gb162971996 120mg/m3 2.1.2 1 20083.42簴30% 1.02620086342.7 4 0.18%40.72% 73.872400029.5 2 İ 鷴 3 2.2 2.2.1 顢顢 10.21% 200 50%300仯1055 2.2.2 彡 彡 彡 2.2.3 2008 29.5 2.2.4 顢 İ İ 4 İ 3. 3.1 2 3.2 豸 豸蹺 乤4 4 3.2.1 1 5 3 2 豸 -30 豸 2硣 3 91% 4 92% 6 3-1 figure 3-1 low-temperature gas used to be absorbent of oil vapor recovery equipment 95% 3-2 figure 3-2 organic solvents used to be absorbent of oil vapor recovery equipment 3.2.2 7 轺 1 豸豸 2 豸豸 5湤 5 8 3-3 figure 3-3 activated carbon used to be absorbent of oil vapor recovery equipment 崵徭 似 20% 5%100pa 510档 彡 9 3.2.3 1 2 2 4 4 3 3 1 3-4 figure 3-4 absorption and adsorption of two oil and gas recovery technology combined with process map ab ab趨 ab20kpa 6 , İ 10 6 95% 3.2.4 -70-80 7 豸乤10%15% 乤豸 1/41/3乤 乤 100800m3/h 乤30潵3c6 3 潵-32c5-32潵-70 c4 鷽 豸 7 乤豸90% 1 岻 20100% 3 4黯巢 www.docin
