Demulsifiers

PZT-DEMUL-1 is a surfactant blend, often an ethoxylated block copolymer, dissolved in an aromatic or other solvent carrier. It migrates to the oil-water interface in produced crude oil emulsions, displacing the natural emulsifying agents (asphaltenes, resins, fine solids) and allowing water droplets to coalesce and settle out by gravity or in separation vessels. Often the single highest-value chemical in upstream production chemistry: without an effective demulsifier, meeting sales spec can require far more expensive heat treatment or long settling residence times.
