【摘要】The present study investigated the wax deposition tendencies of a light Malaysian crude oil (42.4° API),and the wax inhibiting potential of some surfactants and their blends with nanoparticles.With the knowledge that the majority of the wax inhibition research revolved around polymeric wax inhibitors,which cause environmental issues,we highlighted the potential of surfactants and their blend with SiO2 nanoparticles as wax deposition inhibitors.Different surfactants including oil-based,silane-based,Gemini and bio-surfactants were considered as primary surfactants.The primary surfactants and their respective blends at a concentration of 400 ppm were screened as wax inhibitor candidates using cold finger apparatus.The screening results showed a significant influence on the paraffin inhibition efficiency on wax deposition by using 400 ppm of silane-based surfactant,which decreased the wax deposition up to 53.9％ as compared to that of the untreated crude oil.The inhibition efficiency among the silane-based surfactant (highest) and bio-surfactant (lowest) revealed an appreciable
