Aqua-Clear Break 400 & 405 - Demulsifier

DESCRIPTION

Clear Break 400 & 405 effectively "breaks" oilfield emulsions. It works at economical concentrations in a wide variety of oils. Clear Break 400/5 is usually the preferred demulsifier for tank bottoms It rapidly "knocks" out water to reduce BS&W. Clear Break 400/405 is an oil-soluble demulsifying surfactant containing an ammonium salt of a naphthalene sulfonate, with an ethoxylated resin in aromatic solvents.

PURPOSE

Crude oil contains natural surfactants. When mixed with water the natural surfactants can emulsify water into oil. Emulsions are simply water droplets dispersed in crude oil. In some crude oil-producing areas, "reverse" emulsions can occur. They are oil in water emulsions. Emulsions raise the BS&W (bottom sediment and water) of oil, often to the point it is rejected by crude oil purchasers. Emulsions are often very viscous. Heat lowers viscosity and can speed up break time, but often will not completely separate an emulsion by itself.

CHEMISTRY

Surfactant molecules have both an oil-soluble and water-soluble part. Because the oil-soluble part is not soluble in water the surfactant molecule migrates to the oil-water interface. Normally water and oil will not mix; however, when natural surfactants are present in the crude oil, emulsions can form. The surfactant holds the emulsion together by being soluble in both the oil and water. Often sediment such as clay fines, iron fines, etc. are part of the emulsion and help stabilize it. Surface and interfacial tension reduction by Clear Break 400/405 allows water droplets to coalesce into larger droplets, and ultimately separate from the oil. Clear Break 400/405 is formulated to rapidly "drop" water from emulsions.



APPLICATION

The proper demulsifier concentration can be chosen based on a relatively simple bottle test. Normally 30 to 500 ppm is needed. An aromatic solvent should be used if Clear Break 400/405 needs to be diluted.

ADVANTAGES

  • Wide treating of chemical emulsions.
  • Cost-effective compared to heating.
  • Low freezing point.
  • Oil-soluble.
  • Breaks BS&W out of oil.

Safety

WARNING! Break 400/405 contains an aromatic solvent and is volatile in nature. The flash point is below 100°F and is flammable. Do not store Break 400/405 or work with it near open flames or sparks. Vapors may ignite and flash back to the source. Drums may explode when heated. Vent internal drum pressure before opening.

FIRST AID: Break 400/405 may irritate the skin and eyes. If contacted, flush with fresh water for 15 minutes. Wear goggle and rubber gloves. Do not breathe vapors. Victims overcome by vapors should be removed to fresh air.

Read and understand the Material Safety Data sheets.
