The application of anti-agglomerants (AAs) is becoming attractive due to effectiveness at low dosage and high subcooling. However, limited attention has been paid to the synergism effect between different AAs to increase their performance. In this study, anti-agglomeration performance of single and compounded chemical additives using a sapphire rocking cell is evaluated. The experimental results show that cocamidopropyl dimethylamine (AA) combined with sorbitan monooleate (Span 80) exhibits good anti-agglomeration performance. A compounded anti-agglomeration mechanism, in which Span 80 promotes the dispersion of water droplet in the oil phase before the formation of hydrates and AA prevents the agglomeration of hydrate particles formed from water droplets, is proposed. The physical appearance of the octane/brine/AAs mixtures has been studied and related to the anti-agglomeration performance of the AAs.
