Abstract

Abstract The objective of the present work was to evaluate the performance of two-stage adsorber of activated carbon from oil palm empty fruit bunch for methylene blue removal. The model was developed to predict optimum adsorbent mass and time at a specified volumes and concentrations of dye solution. Results show that the adsorbent mass can be reduced by 6.67%. Operating time taken to attain the equilibrium in a two-stage adsorber has dramatically decreased from 22 h to 0.52 h. In the performance evaluation, the adsorbent mass in stage-1 is higher than in stage-2, which lessen the workload to achieve equilibrium. A two-stage adsorber aids to optimize the mass and contact time for different percentage of dye removal that economically feasible for industrial applications.

NaOH预洗油棕果穗活性炭去除亚甲蓝的两级吸附塔优化

摘要本工作的目的是评估两级吸附油棕果穗活性炭去除亚甲基蓝的性能。开发该模型是为了预测在特定体积和浓度的染料溶液下的最佳吸附剂质量和时间。结果表明，吸附剂质量可降低6.67%。在两级吸附器中达到平衡所需的操作时间从22小时显著减少到0.52小时。在性能评估中，第一阶段的吸附剂质量高于第二阶段，这减轻了达到平衡的工作量。两级吸附器有助于优化不同百分比染料去除的质量和接触时间，这在经济上适用于工业应用。

期刊介绍： Chemical Product and Process Modeling (CPPM) is a quarterly journal that publishes theoretical and applied research on product and process design modeling, simulation and optimization. Thanks to its international editorial board, the journal assembles the best papers from around the world on to cover the gap between product and process. The journal brings together chemical and process engineering researchers, practitioners, and software developers in a new forum for the international modeling and simulation community. Topics: equation oriented and modular simulation optimization technology for process and materials design, new modeling techniques shortcut modeling and design approaches performance of commercial and in-house simulation and optimization tools challenges faced in industrial product and process simulation and optimization computational fluid dynamics environmental process, food and pharmaceutical modeling topics drawn from the substantial areas of overlap between modeling and mathematics applied to chemical products and processes.
