The Synergism of PEG to Kinetic Hydrate Inhibitor

摘要

The inhibiting effect of Inhibex 301 for the CH_4 + C_2H_6 + C_3H_8gas mixtures + brine systems was assessed using a high pressuresapphire cell. The onset time of hydrate formation was determined byvisual observation. The hydrate onset time of Inhibex 301 wasprolonged apparently by the addition of polyethylene glycol (PEG).The subcooling of Inhibex 301 was improved dramatically after PEGwas added. PEG is thought to be synergic with Inhibex 301 in thehydrate inhibition.
