Questions about hydrogen reciprocating compressors
Thread Content
Which marine friend has a hydrogenation unit where fresh hydrogen and recycled hydrogen are used together? ? ? How does it work? Can the new hydrogen machine be shut down separately during shutdown?
It’s supposed to be one piece anyway, right? . Circulating hydrogen raises the hydrogen pressure in the entire hydrogenation system to the operating level; as a result, the system loses hydrogen continuously, so it is necessary to continuously supply fresh hydrogen to the circulating hydrogen system. If the supply of fresh hydrogen is stopped, the amount of hydrogen available in the circulation system will eventually become insufficient, causing instability in the hydrogenation unit.
Haven’t seen it. What does \"integrated\" mean here? Does it refer to a compressor that has both functions, or rather a drive unit that simultaneously powers a new hydrogen generator and a circulating hydrogen compressor? If it’s 1 to 2, it can be repaired separately
The combined compressor for fresh hydrogen/circulating hydrogen shares one motor and casing; its different cylinder sections operate independently – there is a fresh hydrogen section and a circulating hydrogen section. It cannot be serviced individually; both sections must be shut down at the same time. This type of compressor has been widely used in the S-ZORB units of various oil refineries in China, and it is a mature design.
Currently, in domestic hydrogenation plants, many facilities use combined models of recycle hydrogen and fresh hydrogen compressors; these are generally imported brands such as PB and Delaiselan. It occupies little space and has low energy consumption, but according to the workshop staff, it is slightly complex to operate.
Is there any information on hydrogen compressors? 17648179839@163.com
Combining compressors saves money; whether it’s possible to do so depends on the scale of the project
Haven’t used it, learned * it~~~~
The new hydrogen and recycled hydrogen share the same motor. The new hydrogen generator cannot be shut down separately
Have you heard of it or seen it? A colleague from another factory told me that they share one compressor for the new hydrogen and recycled hydrogen. I guess we can stop producing new hydrogen and keep using the circulating hydrogen. On the new hydrogen side, whether a return valve, a unloader, or stepless gas flow control is used, it is possible to reduce the pressure and flow rate in order to shut the system down; as long as this process does not affect the force balance of the compressor’s crankshaft, connecting rods, and piston rods
As long as there’s no power outage, everything is fine; once there’s an outage, chaos ensues. How is the construction of the fluidized bed progressing for the poster?
