(35 pts) You are part of a team tasked with designing an absorption column in an oil refinery. The team has tasked you to determine the flooding velocity (ft/s ) and column diameter (ft) for the following conditions of a hydrocarbon absorber equipped with sieve trays. The graph needed is provided at the end of this document.
