Paraffin dispersants

Paraffin is a family of saturated high molecular weight hydrocarbons, and because paraffin deposition occurs in cooler temperatures, they are most commonly found in surface flowlines, particularly offshore where subsea flowlines are cooled by the water temperature at sea bed level. Ideal paraffin dispersants are surfactants, which help to break the deposits. Thermal techniques are also effective, and can be used in combination with dispersing surfactants. Heat melts the paraffin wax to a certain extent, and allows the deposits to be carried along the flowline, reducing the extent of the blockage.
