Novel Biosurfactants for Effective Inhibition of Gas Hydrate Agglomeration and Corrosion in Offshore Oil and Gas Pipelines

ACS Sustainable Chemistry & Engineering, Год журнала: 2022, Номер 11(1), С. 353 - 367

Gas hydrate and corrosion inhibitors are widely used to ensure a successful economic hydrocarbon stream flow inside oil gas pipelines. However, compatibility problems observed during their co-injection into the flowlines as they have different molecular chemistry. Using anti-agglomerant is an effective method control plugging risk in deep-water lines or throughout drilling operations. Here, oleic acid was develop first class of biosurfactants using click chemistry for assurance applications. The results high-pressure autoclave showed that both bio-based anti-agglomerants (BAAs) significantly inhibited agglomeration, value torque remained constant formation process. particles were effectively dispersed liquid paraffin presence 1 wt % BAA1 BAA2. In addition, dynamic simulation revealed headgroup adsorbed on surface, its alkyl chain formed phase slurry. According electrochemical measurements, BAAs highly efficient prevention mild steel saturated H2S CO2-simulated oilfield water. BAA2 completely protected corrosive medium by 99 98.8%, respectively, at 0.1 %. Moreover, adsorption molecules surface physically chemically direction almost parallel surface. Such provides maximum coverage against corrosion. These findings suggest can be potential starting material eco-friendly

Опубликована: Фев. 20, 2023

The extract of waste feverfew root (FRE) is firstly used as green corrosion inhibitors for carbon steel in H2SO4 solution. Weight loss method and electrochemical tests are carried out to evaluate the inhibition efficiency. in-situ scanning vibrating electrode technique applied monitor inhibitive behavior inhibitor. Water contact angle, electron micrograph X-ray photoelectron spectroscopy characterize compositions microstructure products. Results indicate that optimum can reach 98.1% at 400 mg/L, it retain above 91% after immersion 96 h. Based on adsorption isotherm calculation, FRE KI obey Langmuir model. film possesses hydrophobicity effectively retard evasion corrosive media.

A Combined Experimental and Computational (DFT, RDF, MC and MD) Investigation of Epoxy Resin as a Potential Corrosion Inhibitor for Mild Steel in a 0.5 M H2SO4 Environment

Polymers, Год журнала: 2023, Номер 15(8), С. 1967 - 1967

Опубликована: Апрель 21, 2023

In this work, a tetrafunctional epoxy resin entitled 2,3,4,5-tetraglycidyloxy pentanal (TGP) was tested and investigated as potential corrosion inhibitor for mild steel (MS) in 0.5 M H2SO4 solution. The inhibition process employed alongside various techniques, such potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), temperature effect (TE), scanning electron microscopy (SEM), energy-dispersive X-ray (EDS) theoretical approaches (DFT, MC, RDF MD). Further, the efficacies obtained at optimum concentration (10-3 of TGP) were 85.5% (EIS) 88.6% respectively. PDP results indicated that TGP acted same an anodic type SEM EDS analyses found protective layer formed on MS electrode surface presence could prevent attack sulfur ions. DFT calculation provided more information regarding reactivity, geometric properties active centers inhibitory efficiency resin. RDF, MC MD simulations showed have maximum
