减压塔 meaning in Chinese
vacuum distillation tower
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。 - 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。
