Reduced order modeling of a pressure column of an air separation …
网页2023年6月1日 · The Edmister method reduces the size of a column model by aggregating several column trays into segments. It was originally introduced by Edmister (1957) as a steady-state short-cut model based on absorption and stripping factors.

网页基于Pitzer定义式的对应态蒸气压关联方程法，具有代表性的如基于Clapeyron方程的Edmister方程法、Lee—Kesler方程法和最近Daniel基于Antoine方程提出的计算法等。. 每一个蒸气压温度关系式都对应一个w估算关系。. 如果蒸气压按照Clapeyron方程表达：. 则可以推得Edmister ...
Edmisters Method - Refinery Distillation - Brewiki
网页2023年1月16日 · Edmisters Method. Last Updated on Mon, 16 Jan 2023 | Refinery Distillation. ASTM distillation is converted to the true boiling point (TBP) distillation using Edmister's correlation. The blend TBP can be determined simply by adding together the volumes contributed by all the components at a chosen …
13.8. ABSORPTION FACTOR SHORTCUT METHOD OF EDMISTER
网页ABSORPTION FACTOR SHORTCUT METHOD OF EDMISTER. This method finds the product distribution ratio b/ d for each component in a column with known numbers of trays above and below the feed and with a known reflux ratio. The flowsketch and nomenclature appear on Figure 13.13.
Aggregate models based on improved group methods for …
网页2010年8月9日 · The next major improvement to group methods was proposed by Edmister (1957) for handling distillation systems. Unlike Kremser (1930), Edmister (1957) retains the energy balance (2) for the cascade. However, he uses a different set of approximation equations depending upon whether the cascade behaves as an absorber or a stripper.

Edmister's rule for the acentric factor | Semantic Scholar
网页On an overall basis, Edmister's rule represents the acentric factor with an average absolute deviation of 6.2%. The effect of this variation on the calculation of thermodynamic properties is shown to be less than 2%, suggesting the use of Edmister's rule for the application and development of thermophysical property correlations
网页Taylor and Edmister (21, 22). Since complex-hydrocarbon fractions are encountered frequently along with the "discrete" components (e.g., methane, ethane, etc.), it is also essential that a general calculation method have the capability of handling both types of mixtures simultaneously in distillation calcu-lations.
