This study aims to develop a multiphysics model using the finite element method for the simulation of a packed column. This column was filled with ion exchange resins SP112H and GF101, performing purification for the dry washing process mainly to reduce the free fatty acid content (FFA), monoacylglycerol (MAG), diacylglycerol (DAG), and triacylglycerol (TAG) biodiesel samples. Results obtained from simulations were compared to the experimental results for acidity, MAG, DAG and TAG. It was found that the simulation results represented with reasonable agreement the experimental.

用于生物柴油纯化的填充树脂塔的建模和仿真

本研究旨在使用有限元方法开发多物理场模型，以模拟填充柱。该色谱柱装有离子交换树脂SP112H和GF101，主要用于减少干脂肪酸的纯化，以减少游离脂肪酸含量（FFA），单酰基甘油（MAG），二酰基甘油（DAG）和三酰基甘油（TAG）生物柴油样品。从模拟获得的结果与酸度，MAG，DAG和TAG的实验结果进行了比较。结果表明，仿真结果与实验结果吻合良好。
