“…The reliability of the static synthetic isothermal (SynT) apparatus and the experimental procedure employed to measure the solubility of methane and ethane, which are sparingly soluble gases in sweetening solvents, was demonstrated in our previous work . Detailed descriptions of the apparatus and experimental procedure can be found in previous works. ,, The apparatus has a transparent equilibrium cell made from a sapphire tube and two stainless steel flanges with a capacity of 36.29 cm 3 . To monitor the temperature and pressure within the cell, two 100 Ω platinum resistance (Pt-100) probes (WIKA; 1/10 DIN) and a pressure transmitter (WIKA; P-30; 4 MPa) were utilized.…”

The absorption of hydrocarbons into the solvent during the gas-sweetening process is undesirable since this is a fuel source. To address this issue and improve the process design and efficiency, it is important to have a comprehensive understanding of the solubility characteristics of hydrocarbons. Such knowledge plays a crucial role in optimizing the gas-sweetening process and improving the overall production efficiency. The solubilities of methane and ethane in solvent mixtures of diglycolamine, n-methyl-2-pyrrolidone, and water with amine mass fractions of 0.3 and 0.5 were investigated via the static synthetic technique. The data were measured isothermally at 313.15 K with pressures of up to 2.185 MPa. The experimental data were modeled using either the Soave− Redlich−Kwong or Peng−Robinson equations of state. The experimental results indicate that substituting n-methyl-2-pyrrolidone for water in aqueous diglycolamine solvents results in an undesirable increase in the solubility of key natural gas components. However, compared to the use of pure n-methyl-2-pyrrolidone as in the Purisol process, the results show that incorporating amines into the Purisol process could potentially lead to increased carbon dioxide solubility and decreased methane and ethane solubility.

“…The solubility of methane and ethane in the hybrid solvents was measured using a static synthetic isothermal (SynVis) apparatus. The apparatus and experimental procedure were described in detail in previous works. ,, A transparent equilibrium cell with a capacity of 36.29 cm 3 and constructed from a sapphire tube is the core of the apparatus. The cell was submerged into a temperature-regulated water bath to control temperature.…”

Hydrocarbons of natural gas are captured by the solvent in the gas-sweetening absorption process and added to losses in production. Therefore, knowledge of hydrocarbon solubilities in solvents is required to assess and overcome these losses. In this study, the solubility of the main components of natural gas, methane and ethane, in n-methyl-2-pyrrolidone and monoethanolamine-based solvents was determined at the temperature of 313.15 K and pressures up to 2.366 MPa. Mass fractions of 0.10, 0.20, and 0.30 amine in the solutions were used in measurements that were performed using a static-synthetic method. The experimental data were modeled using the Soave−Redlich−Kwong Equation of State. Experimental results showed that the replacement of the aqueous part of conventional monoethanolamine solvents with n-methyl-2-pyrrolidone increased the solubility of desirable components of natural gas which is a negative side effect. The addition of monoethanolamine to n-methyl-2-pyrrolidone outperformed the Purisol solvent in terms of carbon dioxide absorption and decreased hydrocarbon solubility.
