Process design
(OP)
Dear all , Good day
I would like to ask about some issues & if it could be solved.
We here in gas plant consist of three trains SRU & SWEET GAS. We suffering when one of trains or the three trains went shut down, we have to burn all the gases coming from the platform which about 120 km from our plant, in order empty all the line from the platform to the our plant.
The burnt amount is too high & effect the zone around the plant " envori. impact". what i am thinking, is it possible to add pressures vessel could hold all the amount of gas in side the line instead of burnet.

RE: Process design
But your question is not that difficult to answer: The volume in your pipeline can easily be calculated, and the pressure vessel shall be large enough at the pressure your are contemplating (hint either the pressure will be extremely high or the vessel very large or both)

If this is the case, you better investigate what causes the plant/trains to trip and whether there is any way this can be mitigated - maybe to revise interlocks, check the set points, increase reliability/integrity of safety loops, revise operating scenarios etc. We don't know anything about the system you operate so we can't reply with more details.

We have to blow down the gas to the plant flaers. Thai is the company rule.
what i mean it is not possible here as stated in country regulation to burn the gas more the 10 hours in order to avoid the emission to the area.
Now it takes more then 12 hours to burnt all the gases in the line. Even if the platform stopped you still need empty the gas until the pressure in the line minimized
RE: Process design
What i mean here if the plant totally shut down
RE: Process design
To me it seems like a dead end - unless you have an abandoned well suited for re-injection/back production near your plant (or at the upstream end in fact). Again here you would need a compresor for injectiong. Its sems like a much easier taks to challenge these "company rules"
RE: Process design
Hydrate inhibitor wont be practical if you have large volumes of production water to deal with.

Etop is correct, what is the issue?
