distillation yield-
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 % 。Abstract : study is made of recovery of organic reagents during the preparation of ultrafine powder by metal alcoxides hydrolysis. the phase diagrams of isopropanol - benzene system and isopropanol - benzene - water system have been plotted, based on which, isopropanol and benzene can be recovered and recirculated by distillation - rectification process. the recovery and reused rate of alcohol and benzene are above 75 %. so both the environmental pollution and cost of ultrfine powder are reduced
文摘:對醇鹽水解法制備超細粉末過程中有機試劑的回收進行了研究，繪制了異丙醇-苯的二元相圖和異丙醇-苯-水的三元相圖，在此基礎上採用蒸餾-精餾的方法對制備體系中的異丙醇和苯進行回收，將有機試劑循環使用，使醇和苯的回收利用率達75 %以上，因而減少了環境污染，並降低了粉末成本。
