1. Introduction. Natural gas typically contains a wide range of light hydrocarbons, sulfur and nitrogen compounds, and other inorganic molecules [1].The presence of acidic gases in natural gas, in particular sulfur compounds, is a major concern because of their corrosivity, toxicity, and ability to deactivate catalysts [2], [3].Therefore, it is essential to remove these components before the ...

Anthropogenic CO2 emissions are considered the major contributor of greenhouse gas emissions worldwide. The mitigation of this kind of CO2 emissions relies on a portfolio of alternatives where CO2 absorption appears as the nearest approach to be applied at industrial scale. Researchers have been focused on developing new formulations of solvents to make more competitive CO2 absorption as a ...

CO 2 removal from the process and/or fuel gas streams, due to its undeniable significance, is one of the most important research areas in the field of separation and purification of industrial gases, in a way that it is mainly considered as a commitment. The existing standards and the required characteristics of the treated process and/or fuel ...

In terms of physical absorption, there are many methods in industry, such as Rectisol, Selexol, Purisol, Fluor. Burr and Lyddon [16] compared the performance of above four methods, and found that ...

Introduction to Carbon Capture by Solvent‐based Technologies. Toheeb A. Jimoh, ... Jude A. Okolie, in Reference Module in Earth Systems and Environmental Sciences, 2023 Methanol. Methanol is a physical solvent that finds application in the Ifpexol and Rectisol processes of physical absorption. Methanol is not only utilized in a single step in the former to dehydrate and recover liquid while ...

1. Introduction. Natural gas is a multipurpose fuel and a vital resource of energy for the world's economy. It is largely used to generate electricity and run important city cores: from medical department to public safety departments, from national safety departments to every habitual buildings which a community needs (Gürsan and de Gooyert, 2021). ...

Understanding gas sweetening processes. Natural gas produced in gas fields is a mixture of hydrocarbons, mostly C₁ through C₆+, inert gases (N₂, He, H₂, Ar, O₂), acidic gases (CO₂ and/or H₂S), organic sulfur species (RSH, RSR, RSSR) and other impurities. The H₂S content in sour a natural gas spans 0.1 vol%-5 vol%, depending on ...

Solubility of Hydrogen Sulfide in Butanols: Experimental, Modeling, and Molecular Interpretation. The solubility of hydrogen sulfide in 1-butanol, 2-butanol and tertiary butanol was investigated at temperature from 313.15 to 353.15 K and pressures up to 2.3 MPa. The results show that the H2S….

9.6.2 Fluor Solvent Process. The Fluor Solvent process uses propylene carbonate as a physical solvent to remove CO 2 and H 2 S. Propylene carbonate also removes C 3 + hydrocarbons, COS, SO 2, CS 2, and H 2 O from the natural gas stream. Thus, in one step the natural gas can be sweetened and dehydrated to pipeline quality.
