Is it necessary to add a demulsifier to the coked crude gasoline tank?
Thread Content
Our crude gasoline tank is always filled with demulsifier, but I have always felt that it is unnecessary (there is no laboratory analysis to see if oil and water cross each other). What do you think? Hi friends, do you install a crude gasoline tank and add demulsifier?
Ours has never been used, and I have never heard of anyone adding demulsifier to coked crude gasoline tanks!
I haven't heard of adding any demulsifier.
We didn’t add it before, but now we do. If no demulsifier is added, the sulfur-containing sewage will always contain crude gasoline.
If the design of the water bag at the bottom of the crude gasoline pipe is too small and the sulfur-containing sewage does not have enough time to settle, you can consider adding a demulsifier to avoid water in the oil, but the cost is too high.； It is recommended to invest once and add a sulfur-containing sewage tank to ensure settling time and avoid emulsification of sulfur-containing sewage and entrainment of light oil.
We haven't added it either. As long as the tank is large and the boundary is stable, gasoline will generally not be carried. Adding a demulsifier will increase the cost too high.
Isn't that a waste of money? It's not necessary.
If there is an absorption stabilizing system, there is no need to add a demulsifier.
I don't add any water here, it works smoothly without oil.
Reverse phase demulsifier should be added to sewage
There was a time when the crude gasoline and water in our coking workshop could not be separated well. The leader asked us to add some demulsifier, but we did not add it. After a while, it worked, and we needed to strengthen the settling time.
Is this necessary? Because of bringing water? I haven't heard of it!
We don't have it, but coked gasoline will settle in the tank area for a period of time, and the water will be relatively large.
