Due to the combination of low temperatures and high pressure levels, hydrate formation is likely to occur in several types of gas streams. Frames has a long track record in the prevention of hydrate formation. To this end, costly chemicals called hydrate inhibitors are introduced into the production flow. The combination of field experience and process simulation enables us to select the most suitable inhibitor and determine the required amounts to be injected. Commonly applied inhibitors include monoethylene glycol (MEG), diethylene glycol (DEG) and methanol (MeOH).
After having served their purpose, the valuable inhibitors are reused. Various methods are available for recovering the inhibitors, depending on the specific chemical used and the amount of water and/or salts expected.
