Discussion on the thrust issue of the torch pipeline
Thread Content
Petrochemical 3009 specifies the thrust values for various pipe diameters. And it is required that the thrusts do not accumulate. Question 1: Due to geographical constraints, the arm length of the compensator is short; as a result, when the thrust value calculated from stress is close to the thrust required by the standards, should the impact force generated by water hammer be taken into account? If so, how should it be considered? Question 2: Since the thrusts do not add up, will there not be simultaneous release of the flare gas?
Question 1: This should already take into account the impact of condensate. The pipelines of the flammable gas emission system throughout the plant must have a certain slope, allowing condensate to be separated promptly, thereby preventing slug flow or two-phase flow oscillations within the pipes from threatening the safety of the entire system. And there are liquid separation tanks upstream as well. Question 2: It is still possible for the flare gas to be released simultaneously, and this needs to be considered based on the emission conditions of the upstream units; it cannot be simply added up in a linear manner.
