    Portable Building near Potential Pool Fire area

    Guys thanks for the response. Sorry for not providing the detailed information. The stored material is Ethyl Acetate. Dike is provided around the tank. All active safeguards and passive safeguards are available. Blast waves are not reaching to the building. Hence blast is not a concern. Toxic...

    Pool fire near Portable buildings

    Hello We have a portable wood container building with metal cladding placed approx 30 meters away from the Dike of the Hydrocarbon tank. This is potential for Pool Fire. The building is exposed to 37.5 KW/M2 and 20kw/m2 as per the QRA report. There will be 200 people occupying this building...

    Toxic Gas Detector Time Delay

    Issue is false activation, even if we set it at 5 ppm over 1 ppm i will do false activation of deluge. we want to avoid it. One more issue with the detectors that once they detect a value of 10 or 12 ppm of EtO, it will not go back to original within a min, some time in 90 Sec. So if we put 1...

    Toxic Gas Detector Time Delay

    Hello Friends, We have Ethylene Oxide EO toxic gas detectors (GDT)in side plant. These is deluge activation linked to these EO Toxic gas detectors. Once these gas detectors 10 ppm (2 time of STEL) value it will activate Deluge system. EO detectors have inherent cross sensitivity issue and we...

    Safety Factors to consider on plant DBN or increase plant load/capacity

    Just a usual question to friends here. What are the important process safety factors to look into while we are going for process/petrochemical plant capacity increase or DBN. One first though will PSV sizing and release capacity. Does it require adequacy check on fire fighting system also with...

    Pressure reduction for 12 bar gasoline flow to low pressure vessel

    Guys sorry for the providing the limited information initially , as i was just looking for some answer related to high pressure in tank. Just back to question by LI, i agree with you, may be increase in pressure will not be likely scenarios but high velocity could be the concerning to in this...

    Pressure reduction for 12 bar gasoline flow to low pressure vessel

    Regarding your first point, we are connecting pipe to the vessel at bottom side under the liquid level. so it will not be exposed to the vapor space of the vessel. In this case we can avoid hammering impact on the vessel. Flow is 5 M3/hr , we estimate pressure drop along the line is .5 bar...

    Pressure reduction for 12 bar gasoline flow to low pressure vessel

    thanks everyone for the response. actually situation is that we want to contact 2 inch line of gasoline having 12 bar pressure, to a vessel with big volume of 700 M3, vessel is properly vented and connected to flare. @littleinch line is very long, say 500 m, vessel is properly vented. our...

    Pressure reduction for 12 bar gasoline flow to low pressure vessel

    If the pump discharge is 12 barg , line size 2"and if we connect 12 barg gasoline to 0.5 barg vessel(Big volume 700 M3)does it require pressure reduction a Pressure controller. or it is okay of discharge 12 barg to this low pressure vessel?
