Selection of mechanical seals for methanol pumps in methanol-to-hydrogen production
Thread Content
I would like to ask everyone: in the methanol pump seal flushing system of methanol-to-hydrogen plants, the 53B design proposed by the design institute allows the sealing fluid to enter the methanol in case of a leak in the main seal. What problems might this cause in terms of production? What are the actual solutions chosen for implementation in everyone’s devices? Series 53 or 52? Thank you first!
Since the design institute chose the Plan53B flushing scheme under pressure, it proves that it is permissible for the sealing fluid to enter the methanol, as the two are mutually soluble； It also indicates that this process does not allow the medium, methanol, to leak into the atmosphere. Just some personal thoughts, for reference only.
