Properties of fluids under high pressure is of interest for processes design. A literature survey was conducted on experimental vapor-liquid equilibrium (VLE) and density for CO₂+water and CO₂+ethanol. Phase equilibrium and density of pure water, ethanol and CO₂ were evaluated considering 1868 data points. VLE and saturated liquid density data were collected: 544 data points for CO₂+water and 859 data points for CO₂+ethanol. Soave Redlich-Kwong (SRK) equation of state (EoS) with Cubic Plus Association (CPA) was applied for calculation of these properties. Peng-Robinson EoS was evaluated to demonstrate CPA improvement in properties description. The binary interaction parameters were estimated from VLE. For pure compounds, the results indicated suitable description for both phase behavior and density. For CO₂+water, density calculations were accurate (Δρ = 0.5%) and VLE was adequately described (Δx_H2O = 0.49% and Δy_CO2 = 4.63%). CO₂+ethanol volumetric behavior and VLE were also satisfactorily described in CO₂ concentrations up to 30% (Δρ = 2.92%, Δx_EtOH = 1.37% and Δy_CO2 = 5.86%, respectively).

高压下的流体特性对于工艺设计很重要。进行了有关实验气液平衡（VLE）和CO ₂ +水和CO ₂ +乙醇密度的文献调查。考虑到1868个数据点，评估了纯水，乙醇和CO _2的相平衡和密度。VLE和饱和液密度数据的收集：544个数据点为CO ₂ +水和859个数据点的CO ₂+乙醇。具有Cubic Plus Association（CPA）的Soave Redlich-Kwong（SRK）状态方程（EoS）用于计算这些属性。对Peng-Robinson EoS进行了评估，以证明CPA在性能描述方面有所改善。二元相互作用参数由VLE估算。对于纯化合物，结果表明对相行为和密度均适用。对于CO ₂ +水，密度计算是准确的（Δρ= 0.5％）和VLE被充分描述（Δ X _{H 2 O}  = 0.49％，Δ ÿ _CO2  = 4.63％）。CO ₂ +乙醇体积行为和VLE也令人满意地描述CO ₂浓度达到30％（Δρ= 2.92％，Δ X _EtOH中 分别为1.37％和Δy _CO2  = 5.86％。
