Hello, I work in an agro-chemical plant and we are now installing safety relief valves on all our reactors. Ours is a multi-purpose plant and there are constant change overs in the lines . Our avg. reactor size is 16KL , largest and most of them being 20 KL. Our design manager says that the discharge pipe from thr srv can be connected to the vent manifold that runs in the lower floor . The distance between the srv and the manifold on the floor below is about 4 meters (atleast). Can anyone please confirm whether this is a good engineering practice ? Also please clarify any advantages and disadvantages of connecting the srv discharge line to the vent manifold above the srv.
