The role of flushing oil in the residue hydrogenation unit
Thread Content
Hello everyone, I have a question for you: In crude oil hydrogenation units, diesel flushing oil is used in many different areas. What are the functions of this flushing oil? I hope you will kindly share your insights; thank you very much!
Our residue pump uses wax oil as the sealing fluid, as for the diesel flushing fluid, it depends on whether that particular area is to be shut down for replacement
Are you saying it’s to flush the mechanical seal? External flushing oil or something else?
You must be referring to the one used for the heavy oil pump conversion unit.
Do you mean the heavy oil used during pump replacement or flushing? Heavy oil is used for flushing, while nitrogen is used for the light oil pump
Lubrication, cooling, sealing, flushing.
Since residue oil tends to coking and blockage easily, diesel flushing is applied at the lower ends of some instrument pressure lead pipes, such as those for pressure, differential pressure, and flow rate. These pipes should be flushed regularly to ensure accurate instrument readings.
If it’s on the pump, it’s basically used to flush the mechanical seal
It seems that the seals of the pumps, the instruments, and the special valves all need to be flushed. Prevent clogging and equipment damage.
Hello, could you send me some information on residue oil hydrogenation?~! ~Thank you! ! ! Email: jiaohua2016@163.com
