The absorption and solubility of pure ethane and ethylene gases were investigated in an experimental pressure decay setup, where a small amount of silver nanoparticles was added to pure N-methyl-2-pyrrolidone (NMP) solvent. All the experiments were performed at temperatures of 278.15, 298.15 and 328.15 K and different pressures (up to the gases dew points) as well as different concentrations of silver nanoparticles (0.05 and 0.1 g/l). The kinetic data of absorption, Henry’s law constants, heat of absorption, entropy, Gibbs free energy, and ideal selectivity were reported. Also, the effects of temperature, pressure, and nanoparticle concentration on the equilibrium results were evaluated. The absorption results revealed that the presence of small amounts of nanoparticles in the solvent intensified the absorption performance between 1.5–18 % for ethylene and 1–41 % for ethane. The results also showed that the solubility of ethylene in pure solvent and nanofluids was better than that of ethane. Increasing the nanosilver concentration up to 0.1 g/l resulted in reducing the absorption equilibrium time specially for ethylene/nanofluid experiments. Also, the ideal ethylene/ethane selectivity improved by increasing the nanoparticle concentration at the same temperature.

吸收和纯乙烷和乙烯气体的溶解度在实验压力衰减setup，其中加入到纯的银纳米颗粒的少量进行了调查Ñ-甲基-2-吡咯烷酮（NMP）溶剂。所有实验均在278.15、298.15和328.15 K的温度，不同的压力（达到气体露点）以及不同浓度的银纳米颗粒（0.05和0.1 g / l）下进行。报告了吸收动力学数据，亨利定律常数，吸收热，熵，吉布斯自由能和理想选择性。此外，评估了温度，压力和纳米颗粒浓度对平衡结果的影响。吸收结果表明，溶剂中少量纳米颗粒的存在增强了乙烯的1.5–18％和乙烷的1–41％的吸收性能。结果还表明，乙烯在纯溶剂和纳米流体中的溶解度优于乙烷。将纳米银浓度提高到0.1 g / l可以减少吸收平衡时间，特别是对于乙烯/纳米流体实验。同样，通过增加相同温度下的纳米粒子浓度，可以提高理想的乙烯/乙烷选择性。
