But the temperature difference at the vertical direction in combustion chamber in lead column, that is said by operator, is over 60 ?. ( 2 ) according to the experiences in the practice, the second layer air and the second layer gas had a little effect of support burning, and the third air has little effect for combustion, and the power to drawing exhaust gas can only be adjusted in limited range. the problems, it is said above, restricted more advance of some kinds of technology and economy target in spelter refining in new jersey furnace
由於鋅精餾爐產量提高,一些問題開始暴露出來: ( 1 )燃燒室?舶要求溫度差不超過10 ,而從現場反映的情況來看,燃燒室上、中、下部溫度差已超過60 ; ( 2 )在生產實踐中,發現燃燒室第二層空氣、第二層煤氣作用甚小,第三層空氣失去助燃作用,廢氣出口的抽力可調范圍有限;以上這些問題在客觀上制約了精餾塔在鋅精煉中各項技術經濟指標的進一步提高。The recovery of atmospheric light oil yield of atmospheric in the northern atmospheric distillation tower of shenghua teaching & test factory, science and technology group of china university of petroleum has been increase by about 4 or 5 percent through the following methods : changing the tray perforation of atmospheric tower, adjusting the amount of stripping steam and the outlet temperature of the atmospheric heater and merging atmospheric excess vapor into 3rd atmospheric drawn - stream to keep the fractions content of bottom oil below 5 % before 350
摘要中國石油大學科技集團勝華教學實驗廠北常減壓蒸餾裝置換煉勝利管輸油后,通過改變常壓塔塔盤開孔率、調節常壓塔汽提蒸汽量和常壓爐出口溫度、常壓過汽化油併入常三抽出線等措施,控制常壓塔底油350前餾分含量小於5 % ,使常壓輕質油收率提高約4 % ~ 5 % 。The leakage and treatment of solvent desorber in a butadiene unit of organic synthesis plant are introduced
