Breaking strong oil in water emulsion
Breaking strong oil in water emulsion
(OP)
Hello all,
I am seeking your advice on the following:
The inlet separators are now oversized due to lower plant inlet, I thought that this should be helping in the emulsion as it provides more residence time, however, when one of the inlet separators was isolated for a while, other vessels showed better level control, I could not collect analysis, but looks like it was less emulsion. How can the over sizing affect the separation and emulsion?
The HP inlet separators operate at around 90 psig, water then goes to second separation stage at 35 psig, and then it flows to big settling tank at atmospheric conditions. Water clarifier is currently injected at the outlet streams from the second stage separation. This system is not efficient in breaking emulsion, I am thinking of installing a coalescer in this system. Can you give me some hints to proceed, suggest some suppliers, I am staying at UAE.
Thank you.

Thanks.

Can you please explain more how to use them, do you mean injecting cationic polymer water clarifier at one point in the system and then inject an anionic water clarifier at a following point downstream? also, can you recomment a reference for the cationic and anionic clarifiers.
Thank you.
