Precipitation of asphaltenes in porous media undesirably influences oil recovery due to pore clogging and subsequent wettability alteration. This study reports, primarily, the potential application of two environmentally-friendly chems., a hydrophobic deep eutectic solvent (DES) and a glycolipid biosurfactant known as rhamnolipid (RL), as asphaltene precipitation inhibitors. While DES was prepared by mixing glycerol, as its hydrogen bond donor (HBD) component, with methyltrioctylammonium chloride, as its hydrogen bond acceptor (HBA) component, RL was extracted from the native strain of Pseudomonas aeruginosa. The inhibition potential of these green chems. was then characterized from exptl. and theor. perspectives. In the exptl. part, the inhibition efficacy of both chems. was initially confirmed based on the precipitation experiments Next, filtration and optical microscopy provided evidence of chem. interaction between inhibitors and asphaltenes. To further illustrate the structural alteration of asphaltenes recovered from the inhibitor-included solutions, Fourier transform IR and elemental analyses were conducted. Results revealed that the dominant inhibition mechanism of DES was the cracking/dissolution of asphaltene particles compared to peptization in the case of RL. Increased oxygen content and H/C ratio plus the decreased aromaticity index of the asphaltenes recovered from the DES-containing solution compared with those of the raw asphaltene were indications of the dissolution mechanism. In addition, comparing the performance of synthesized chems. with a conventional inhibitor, dodecylbenzene sulfonic acid, revealed the preferable performance of the chems. In the theor. part, the propensity of asphaltene precipitation was studied using the surface energy concept based on the extended DLVO theory. The results showed that acid-base interactions among different sub-components of the surface energy played a key role in retarding asphaltene precipitation by decreasing the attraction force between similar asphaltene particles, further supported by the concepts of work of cohesion and adhesion. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Computed Properties of C25H54ClN).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Computed Properties of C25H54ClN
