Abstract. Natural gas (NG) must be treated to remove sulphur compounds and acid gases i.e., carbon dioxide (CO2) hydrogen sulfide (H2S) ensure that it complies with requirements for sale transportation. More than 95% of the NG processing plants are operated through removal unit (AGRU) using aqueous amine solvent in removing sour components from hydrocarbon due availability at a low cost. Howeve...

In this work, a mathematical model is established to describe the removal of CO2 from gaseous mixtures including CH4 and CO2 in a polypropylene hollow fiber membrane contactor in the presence of conventional absorbents such as monoethanolamine (MEA), methyldiethanolamine (MDEA), and a blend of them. Modeling was performed in axial and radial directions under the fully-wet condition for counterc...

BACKGROUND Colorectal cancers (CRC) are associated with perturbations in cellular amino acids, nucleotides, pentose-phosphate pathway carbohydrates, and glycolytic, gluconeogenic, and tricarboxylic acid intermediates. A non-targeted global metabolome approach was utilized for exploring human CRC, adjacent mucosa, and stool. In this pilot study, we identified metabolite profile differences betwe...

Asbestos-free gaskets have been used to seal flanged connections on various applications. This paper discusses the use of a different style of gasket and details the advantages and benefits resulting from such a change. The discussion includes an analysis, supported by laboratory testing and successful field experiences. The paper is sectioned into three case studies, each topic relating to a t...

Validation of a Liquid Chromatography Tandem Mass Spectrometry Method for Targeted Degradation Compounds of Ethanolamine Used in CO2 Capture: Application to Real Samples — In the field of greenhouse gas emission, a promising approach consists in CO2 storage and capture. However most of the processes are based on amine solutions which are likely to Oil & Gas Science and Technology – Rev. IFP Ene...

The synthesis, gas sorption studies, magnetic properties, and theoretical studies of new molecular wheels of core type {Mn8Ln III 8} (Ln=Dy, Ho, Er, Y and Yb), using the ligand mdeaH2, in the presence of ortho-toluic or benzoic acid are reported. From the seven wheels studied the {Mn8Dy8} and {Mn8Y8} analogues exhibit SMM behavior as determined from ac susceptibility experiments in a zero stati...
