Hydrate Formation at Pipe Bends

Hydrate Formation at Pipe Bends

Hydrate Formation at Pipe Bends

(OP)
I am looking at wet natural gas piping system.

An expert has advised that hydrate crystals have a tendency to accumulate at piping bends (radius < 3d).

Intuitively, this does not seem right. Also I have been unable to find any references to the phenomenum on the internet.

Has anyone got any knowledge about this?

RE: Hydrate Formation at Pipe Bends

Accumulation at piping bends seems logical to me.
Formation, however, should be irrelevant to the fittings/bends.

RE: Hydrate Formation at Pipe Bends

Hydrates are crystals which means in solid form. Accumulation of solids is quite relevant at low points & fittings.

Thanks for your thoughts.

In my application, gas will be flowing round bends at > 10m/s.

Intuitively, it seems to me that bends will not cause accumulation of hydrate crystals in such circumstances.

For more details, see similar posts in Chemical Process Engineering.
