Problem of scaling in the vacuum tower: The filter at the inlet of Pump 1 in Line 1 is clogged with black substance.
Thread Content
The flow rate from the primary pump was not good; upon removing the inlet filter, it was found to be filled with black gel-like substance. After being cleared away, it dissolves with just a splash of water, but it doesn’t dissolve in oil; I don’t know what it is. Does anyone who knows know about this? Please give an analysis
It would be best to include a photo; it should dissolve in water but not in oil, probably salts.
Ammonium salt scaling – I have agents to prevent ammonium salt scaling. Do you need them?
Ammonium chloride should be a white scale, right?
Pure ones are definitely white, but those that are contaminated and contain impurities will change color
I don’t know what raw materials the poster used for processing! But it dissolves when rinsed with water; it must be salts! Since it is soluble in water, filling it with water can resolve the blockage issue, if the process permits it!
There should still be some iron chloride crystals left.
To improve oil recovery, oil fields require tertiary oil recovery, for which surfactants such as polyacrylamide or other polymers are used (usually organic ammonium compounds, which are soluble in water but not in oil and do not decompose at certain temperatures). Primary oil recovery is carried out without the use of any surfactants; secondary oil recovery uses water as a surfactant, while tertiary oil recovery employs a variety of surfactants, with polymers being one of them. These polymers are soluble in water but not in oil, and they may be carried into atmospheric and vacuum distillation units. Since they are insoluble in oil, they tend to deposit in dead zones within equipment or pipelines. Due to temperature changes, condensation reactions may also occur, resulting in the formation of gel-like substances. & m) Y4 Z' M; `
