Demulsifiers

Describes as the the separation of water from crude oil. As crude oil is produced from a reservoir it tends to become mixed with either natural formation water or mixed formation and injection water. This produced mixture of crude oil and water is termed an oil and water emulsion. It is critical to topsides process operations that the crude oil is efficiently and quickly separated from the water to allow dry oil to be exported and clean water to be discharged within consent, thus maximizing crude oil value and minimizing operating costs

Some factors which affect the breaking of crude oil emulsions:  

• Particle Size
  
• Difference in density between oil and water
  
• Temperature and oil viscosity
  
• Flow and type characteristics of emulsifying agent
  
• Treating rate
  
• Mixing and settling time
  
• Type of treating vessel
  

ATC offers breaking emulsion products ranging from those occuring in cruide oils to those formed in water effluents.  ATC demulsifier products are well proven separation of solids from acqueous solutions in the waste waters.  ATC's emulsion breaker will achieved the following:

• Fast and thorough breaking of crude oil emulsions
• Lowered residual BS&W in many cases to zero
  
• Lowered treating cost
  
• Lowered heating requirements in demulsification
  
• Increased crude oil gravity and value
  
• Lower transportation cost
  
• Minimized corrosion of equipment and pipelines
  
• Minimized build up of inter facial layers
  
• Removal of iron sulfide and other solids from oil and oil-water interfaces
  
• Inhibition of scale and mineral deposits in oil transport systems
  
• Inhibition of tank bottoms and slop oils.
