We are working on offshore oil and gas processing system.
We have flare KOD with ESD 2 in case of LAHH. ESD 2 causes plant to close. As of now liquid from flare KOD is pump backed to main plant by a pump for reprocessing. My question is how to restart plant in case of ESD2 as we will not be able to pump KOD liquid back to main process. On other side it is preferable to empty KOD before plant startup.
Some of the solution given below
1) bypass ESD2 of flare KOD for startup (which i am not comfortable with) due to ESD bypass plus starting process with LAHH in flare KOD
2) Divert KOD liquid to separate tank (which we have), which can be diverted to main process for reprocessing after process is stabilized
