Dear Sirs, i am sizing the flare stack for compressor station. i calculated the volume of isolated sections and done the depresuring dynamic model and calculated the peak flow rates.
The following sections i have considered which shall be depressurized. The case 1 shall be depressurized on staggered mode. But i am not sure about case 2 blocked discharge flow rate depressuring.
Case 1
- Inlet header peak flow rate 13000 kg/hr due to low pressure
- Each compressor train after settle out conditions peak flow rate 11000 kg/hr
- Outlet header peak flow rate 80000 kg/hr due to high pressure
- Gas pipeline 16 km section peak flow rate 50000 kg/hr
Case 2.
- Each Gas Compressor blocked discharge flow rate 70000 kg/hr
- Four Gas Compressor blocked discharge flow rate 280000 kg/hr
Please guide me about the worst scenario. so that i may take the flow rate to size the stack diameter and sterile area for 4.73 kw/m2 radiations. This is urgent sir
Thanks
Hafiz
