Question: Is it possible to operate the water injection buffer tank at atmospheric pressure, or is nitrogen sealing required?
Thread Content
Can a water injection buffer tank operate at atmospheric pressure, or is nitrogen sealing required? According to the documents, it is indeed nitrogen-sealed to prevent water oxidation; however, as far as I know, several of these systems operate with an open design… I’m confused
They are usually open-type and do not require nitrogen sealing; how can oxidation occur at lower temperatures?
Oh, what kind of technique is it? Is the water requirement very high? Water generally doesn’t oxidize, right?
Thank you ·· P.S. What if it’s purified water? ··
I am dealing with those that are nitrogen-sealed. Let’s take a look at what device it is. 1# dpl613000
It is possible to use nitrogen sealing or gas sealing, for the following reasons: 1. To isolate the tank from the atmosphere and prevent oxygen from causing corrosion of the pipe walls； 2. Increase the inlet pressure of the injection pump to boost the processing capacity ； 3. Increase the inlet pressure of the injection pump to prevent cavitation and protect the pump.
Our hydrogen and water injection tanks are also sealed with gas
I wonder if your manufacturing process uses acidic water for injection, because acidic water contains sulfur, which can lead to spontaneous combustion of FeS; therefore, nitrogen sealing is necessary.
No, the purpose of nitrogen sealing is to prevent dissolved oxygen from entering the water and reaching the reactor.
