As for the existing benzene-spurting for the stand-by distillating pump since test running, we analyse it from the aspects of operation and design and raise the corresponding innovative approach.
The extraction and refining process includes distillating washing oil or anthracene oil to get fluorene distillate, then crystallizing the fluorene distillate to get fluorene using cooling or solvent.
The method, especially the conditions of determining nitrogen in plant, is studied. The results obtained show that compared with distillating method, it is simple, safe and accurate.
研究了用气提滴定法测定植物中氮的条件和方法。实验结果表明,与蒸馏法相比,方法简便安全,结果準确。
The results showed that the method was simpler, safer and more accurate compared with distillating method. Furthermore, about 90% electricity was saved by this method.
实验结果表明,与蒸馏滴定法相比,丘氏法简便安全,结果準确可靠。
The main production facilities are mixing device, reactor, air cooler, water scrubber, caustic wash tower, compressing machine, condensate cooler, dissociator and distillating column and so on.
