  1. Through analyzing the effect of temperature and nitrogen on crude oil viscosity the influences of different nitrogen injection volume and injection modes on steam displacement are contrasted, the mechanism of nitrogen - assisted steam stimulation is clarified, which includes : heat carrying capacity is raised, the saturation of remaining oil is reduced after nitrogen - assisted injection is made ; crude oil flow is enhanced because of nitrogen compression and dispersion and the change of oil flow shape ; water back - production rate is improved by expanding the steam sweep volume and compensating in - situ energy ; steam distillation effect is enhanced

    通過分析溫度、氮氣對原油粘度的影響,對比不同注氮量、不同注入方式等對蒸汽驅油效果的影響,弄清了氮氣輔助蒸汽增產的機理主要表現在:氮氣輔助后增加攜熱能力,降低殘余油飽和度,氮氣的壓縮膨脹作用分散和改變了原油流動形態,增強了原油流動性;擴大蒸汽的波及體積,補充地層能量,提高回採水率,強化蒸汽蒸餾效應。
  2. Whether the fluid of coarse liquid zinc is steady or not is one of the most important factors that effect the life of distillation column and the output and quality of product meanwhile, it also much affects the recovery rate of valuable metals

    粗鋅液流量穩定與否,是影響精餾塔壽命以及鋅產品產量和質量的最重要因素之一;同時,它對有價金屬的回收率也將產生很大的影響。
  3. 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。
