灵敏板 meaning in English
sensitive plate
Examples
- Some of problems in distillation technology process are studied using excel , matlab and chemcad . they are distillation with simple balance , determining accurately the position of sensitive plates in distillation tower , distillation of multi - components , and crude distillation at steady state . this paper shows how to solve bubble & dew points for binary ideal system and five cases of flash by means of excel and analizes reducing pressure affects on phase equilibrium as an example of distillation and separation ethyl benzene & phenyl ethylene below atmosphere
基于excel 、 matlab和chemcad软件,对蒸馏过程中的简单平衡蒸馏、精馏塔灵敏板位置确定方法、多组分精馏等进行了数值计算与定量研究,对原油炼制常减压塔进行了初步的稳态模拟,实现了用excel求解双组分理想体系的泡、露点问题和闪蒸计算的五种情况,并分析了减压对其相平衡的影响。 - Results of calculation indicate that the bubble & dew points may be reduced extremely , but the relative volatility rises slightly and the separation of them is affected hardly by decreasing pressure . and this article puts forward more reasonable modifying suggestions after analyzing numerically in detail the common method of determining the position of sensitive plate in distillation tower and finds out something unsatisfactory about it
计算结果表明,减压可大大降低乙苯?苯乙烯物系的泡、露点,但相对挥发度增加甚微,对其分离的难易程度几乎无影响;对常用求取精馏塔灵敏板位置的方法进行了详尽的数值分析,对其不合理性提出了改进措施。 - The results indicate that the position of sensitive plates is located at the section of middle or upper in tower but not near by feeding plate , and the smaller reflux ratio , the closer overhead of distillation tower . accurate calculation for flash is solved using matlab , and the result is correct and reasonable . complicated multi - components distillation and crude distillation are simulated using chemcad , and results are reasonable about profiles of flow for vapor and liquid as well as temperature in the tower
数值分析的结果表明精馏塔灵敏板位置并不在进料板附近,而是位于精馏段的中上部,且回流比愈小,愈靠近塔顶;利用matlab实现了蒸馏过程的严格计算,与参考值比较,结果正确、合理;借助于chemcad进行常减压塔的稳态模拟计算,得出了流量和温度在塔内的分布,经过理论分析,结果合理,可为实际生产提供参考。
