Mass Transfer Solver Tool: A software to calculate mass transfer coefficients for Packed-bed Columns

The Mass Transfer Solver Tool is a calculation software for gas-liquid mass transfer coefficients for random and structured packed-bed columns. This software refers to the work of Flagiello et al. (2021) entitled "A tool for mass transfer evaluation in packed-bed columns for chemical engineering students" and published in the scientific journal of Education for Chemical Engineers (https://doi.org/10.1016/j.ece.2021.08.001).

The MT Solver Tool is based on the use of the most acknowledged models available in the pertinent literature (Onda et al., 1968; Bravo et al., 1985, 1992; Billet and Schultes, 1993; Brunazzi and Paglianti, 1997; Olujić et al. , 2004; Hanley and Chen, 2012) to calculate the gas-side (ky), liquid-side (kx) and interfacial area (ae) coefficients separately.
The software includes a "Library File" where geometric data and model fitting parameters for 144 different packings in size and materials are available. The spreadsheet file "MT Solver" operating in default mode uses the data of the 144 packings available in the "Library File" to calculate the mass transfer coefficients. Futhermore, the software can also be operated in user-defined mode "User-defined MT Solver" in order to customize and expand its use when the considered packing is not included in the Library File.

The MT Solver Tool was also used in teaching activities in the academic year 2020-2021 for the Unit Operation and Sustainable Process Design courses of the Master's degree in Chemical Engineering, at the University of Naples Federico II.

All the instructions for use are given in the work: A tool for mass transfer evaluation in packed-bed columns for chemical engineering students (https://doi.org/10.1016/j.ece.2021.08.001).

Any system bugs, calculation errors deriving from the model equations or the parameters set in the library can be reported to the email address: [e-mail] (Dr. Domenico Flagiello).
Suggestions for model equations updates or data and packing parameter values ​​included in the library (or new data packing) are also welcome.

传质求解工具（Mass Transfer Solver Tool）是一款用于计算随机填料与规整填料塔气液传质系数的计算软件。本软件参考了Flagiello等人2021年发表于《化学工程教育》（Education for Chemical Engineers）期刊的题为《面向化工专业学生的填料塔传质评估工具》的研究（https://doi.org/10.1016/j.ece.2021.08.001）。传质求解工具基于领域内公认的经典文献模型（Onda等，1968；Bravo等，1985、1992；Billet与Schultes，1993；Brunazzi与Paglianti，1997；Olujić等，2004；Hanley与Chen，2012），可分别计算气相侧传质系数（ky）、液相侧传质系数（kx）及相界面积（ae）。该软件内置“库文件（Library File）”，收录了144种不同尺寸、材质的填料的几何数据与模型拟合参数。默认运行的“传质求解器”电子表格文件将调用“库文件”中的144种填料数据完成传质系数计算。此外，当所需填料未收录于库文件时，可切换至“自定义传质求解器（User-defined MT Solver）”用户自定义模式，以拓展工具的适用范围。该传质求解工具曾于2020-2021学年，在那不勒斯费德里克二世大学化学工程硕士专业的“单元操作”与“可持续过程设计”课程教学中投入使用。完整的使用说明详见前述研究论文：《面向化工专业学生的填料塔传质评估工具》（https://doi.org/10.1016/j.ece.2021.08.001）。若发现系统漏洞、由模型方程或库参数设置引发的计算错误，请致邮至邮箱[e-mail]（多梅尼科·弗拉吉耶洛博士）。同时欢迎提交关于模型方程更新、库内填料数据与参数优化（或新增填料数据）的相关建议。
