This riser shall be at least 30 meters away from any furnace regardless of the height of riser. Prv discharging hydrocarbon vapors to atmosphere should be provided with outlet piping, at least 3 meters above any equipment within a horizontal distance of 15 meter or 4.5 meter above the roof of the nearest building whichever is higher. On the other hand, improper design of psv outlet (tail) pipe may cause excessive backpressure resulting into performance reduction of the psv. While a piping system can use the set point of a pressure relieving device on an equipment item it is connected to as its design pressure, it can only do so if there is no means to isolate that piping from the relief device.
