The excessive foam can lead to the reduction of the separator capacity as well as its efficiency. A defoamer is needed to break and destroy the foam in the separator. There are many commercially available defoamer agents in the market, but not all defoamers are suitable for every application. For this reason, four modified silicone-based defoamers were successfully synthesized and characterized based on the data obtained from the screening process using various commercial defoamers. The performance of modified defoamers was evaluated using TECLIS FoamScan that imitate real conditions of treatment. The results show that all four of the modified silicone-based defoamers, especially amide-terminated-modified defoamers (S2) showed excellent performance as a defoaming agent to mitigate foam in specific conditions. The best-case condition for the modified defoamer to perform was at a high temperature (60 °C), gas flow rate of 1.0 L/min, and low ration concentration of the surfactant to brine (30:70). The study on the bubble count and distribution using a KR�SS Dynamic Foam Analyzer revealed that S2 excellently contributes to the formation of unstable foam that can fasten foam destruction in the foaming system. © date: 2021 publisher: American Chemical Society official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85108830035&doi=10.1021%2facsomega.1c00350&partnerID=40&md5=f8cadfd1901da5503cf4f099d0c4979a id_number: 10.1021/acsomega.1c00350 full_text_status: none publication: ACS Omega volume: 6 number: 23 pagerange: 14806-14818 refereed: TRUE issn: 24701343 citation: Hassan, A. and Jumbri, K. and Ramli, A. and Borhan, N.
