Abstract

Aldol polymer fouling in petrochemical plant is an undesirable process, which needs to be removed for increasing the efficiency of downstream process. In this paper, inhibition and dissolution efficiency of the aminopropyl trimethoxy silane (APTMS), aminopropyl triethoxy silane (APTES), sodium salt of aminopropyl trimethoxy silane (SS-APTMS), sodium salt of aminopropyl triethoxy silane (SS-APTES) were studied at different molar ratio of vinyl acetate (VA):amino alkoxy silane (antipolymerant). The sodium salt of 6-aminohexanoic acid (SS-AHA) and ethanolamine (EA) were used as reference for comparison. The efficiency of antipolymerant for inhibition and dissolution was measured as percentage transmission (% T) by UV spectrophotometry. Solium salt of amino alkoxy silane showed good efficiency for inhibition and dissolution process. Furthermore, the presence of alkoxy group with amino group facilitates inhibition as well as dissolution of aldol polymer in alkaline media, while compounds with amino group acts as inhibitor for aldol condensation only.

Keywords: Aldol condensation, fouling, inhibition, dissolution, amino alkoxy silane, % transmission
