good day gentlemen
in my plant there is tank which is store the liquid ethylene product. A small portion of the liquid flashes to vapor during the transfer. The vapor rises through the liquid and exist the tank overhead to ethylene compressor. the liquid is transfer to other unit by utilizing pumps. there is a nitrogen line on the tank which is open to pulling a vacuum on the tank and to protect compressor and pump.
I want to calculate the required nitrogen flow to protect the pump and compressor if there is low pressure on the tank . Is there any way to calculate it
thanks for help
