Abstract

In this work, we measure the density and viscosity of CO₂ saturated orange peel oil liquid mixtures under moderated pressure for the purpose of supercritical process engineering design. A high-pressure falling weight viscometer is used to measure the viscosity of saturated liquid mixtures of orange oil + CO₂ at different temperatures (293 K to 333 K) and saturated pressures (2 MPa to 10.3 MPa). An important variation of viscosity (0.35.10⁻³ Pa.s to 1.10 10⁻³ Pa.s) is reported in the range of operating conditions. Results show the operating temperature influences the viscosity of both the pure oil and the CO₂-saturated oily substrates. The new viscosity data correlates with a simple Arrhenius modified type model.

加压二氧化碳饱和橙皮油的密度和粘度

在这项工作中，我们测量了二氧化碳饱和橘皮油液体混合物在适度压力下的密度和粘度，目的是进行超临界工艺工程设计。我们使用高压失重式粘度计测量了橘子油 + CO2 饱和液体混合物在不同温度（293 K 至 333 K）和饱和压力（2 MPa 至 10.3 MPa）下的粘度。据报告，在工作条件范围内，粘度的变化很大（0.35.10-3 Pa.s 至 1.10 10-3 Pa.s）。结果表明，工作温度会影响纯油和二氧化碳饱和油基的粘度。新的粘度数据与简单的阿伦尼斯改进型模型相关。

期刊介绍： The Journal of Supercritical Fluids is an international journal devoted to the fundamental and applied aspects of supercritical fluids and processes. Its aim is to provide a focused platform for academic and industrial researchers to report their findings and to have ready access to the advances in this rapidly growing field. Its coverage is multidisciplinary and includes both basic and applied topics. Thermodynamics and phase equilibria, reaction kinetics and rate processes, thermal and transport properties, and all topics related to processing such as separations (extraction, fractionation, purification, chromatography) nucleation and impregnation are within the scope. Accounts of specific engineering applications such as those encountered in food, fuel, natural products, minerals, pharmaceuticals and polymer industries are included. Topics related to high pressure equipment design, analytical techniques, sensors, and process control methodologies are also within the scope of the journal.
