INTRODUCTION •
A flash separator is a device or an equipment used in several industrial applications to separate a vapour- liquid mixture. It is performed to determine the product condition and phases. It is referred also to as flash drum or knock- out drums.
PROBLEM STATEMENT
We have a stream containing 15% ethane, 20% propane, 60% i- butane, and 5% n- butane at 50°F and atmospheric pressure and a flowrate of 100lbmoles/hr. Th compressed to 50 psia, and then cooled to 32°F. The resulting vapour and liquid are to be separated as the two product streams. What the flowrates and compositions of these two streams?
