Solubility data for CO2 in monoethylene glycol (MEG) are limited in the open literature with most of the data limited to temperatures above 298.15 K through a small number of sources. This work focused on the solubility of CO2 in pure MEG in a wider range of temperatures and pressures as experimental data in such conditions are extremely limited in the open literature. These results can be used to optimize EoS and increase prediction reliability due to the wider range. The solubility of CO2 in MEG was measured between 263.15–343.15 K and 0.2–40.3 MPa. The experimental results from this study are compared to available data from the open literature together with the CPA-SRK72 calculations. The data from this work together and open literature were used to calculate a binary interaction parameter (BIP) of 0.053 between 263.15–398.15 K to correlate the experimental data. The experimental results showed an overall absolute average deviation of 4.81% from the calculated modeling results.

单乙二醇中CO 2在263.15–343.15 K和0.2–40.3 MPa之间的相行为:一种实验和建模方法

在公开文献中,CO 2在单乙二醇(MEG)中的溶解度数据受到限制,大多数数据通过少量来源限制在高于298.15 K的温度下。这项工作集中于在更宽的温度和压力范围内,CO 2在纯MEG中的溶解度,因为在这种条件下的实验数据在公开文献中极为有限。由于范围更广,这些结果可用于优化EoS并提高预测可靠性。CO 2的溶解度MEG的测量值介于263.15–343.15 K和0.2–40.3 MPa之间。将这项研究的实验结果与公开文献中的可用数据以及CPA-SRK72计算结果进行比较。来自这项工作的数据和公开文献被用于计算263.15–398.15 K之间的0.053的二元相互作用参数(BIP),以关联实验数据。实验结果表明,与计算的建模结果相比,整体绝对平均偏差为4.81%。
