Q 1: The 40t/h ethane feed to the plant is at a pressure of 9 bar g and a temperature of 40 deg C. Calculate the ethane line size (use a velocity of 20m/s as economic gas velocity).
Q 2. What size would be a good guesstimate for a flow control valve in the ethane line
Verified Expert
The report attached mentioned the ways how to estimate the pipe dimensions as well as the dimensions of the control valve employed in the flow line. The data provided is about the ethane flow at 40-degree celsius as well other information like economic flow rate provided. Characteristic gas equation is employed to find the volume flow rate and from that the actual dimensions of the pipe and the control valve are calculated.
