AnonymousWhat kind of De-emulsifier is the most effective in Coker Blowdown system? Any Coker out there without deemulsifier in this system?
-
AnonymousTypically we used RE-SOLV® EC2345A (nalco) , with good results. sometime the main concern is the injection point, since some units were designed with deemulsifier injection in the blowdown drum, being the better in the line going to this drum (near the exit of the blowdown aircooler condenser, main line)

Anonymouswe use nalco demulsifier as well…though…the system rarely works….the blowdown overhead settler is good enough is segregating the water & oil……
-
Anonymouswhere is the injection point on the drum or inlet line? have you made field tests with diferent de-emulsifier?
-
Anonymousin the case of sour water which possesses free hydrocarbons, which further actions would be taken to a higher dose of demulsifier as NALCO Chemical my provider ensures that the effect of free hydrocarbons in the sour water is due to mechanical defect sedimentation drum purge.

AnonymousThese drums are designed to generate the separation of sedimentation, chemical for use in our plant is the RE-SOLV ® EC2345A (Nalco) that accelerates the process of demulsification.
Where our work is NALCO chemical supplier and its views of the hydrocarbons in the water free sour is due to the mechanical design of the drums, so that I have read and researched the effect of the chemical in the emulsion is subject to adequate dosage to be injected to the settling tank and other factors such as oil viscosity, the residence time in the drums, well defined with these parameters is that there should be a good dosage would generate the optimal separation of the emulsion and remove free hydrocarbons in the sour water.
