Question

Conditions for the bottoms at 230°F and 280 psia from a depropanizer distillation unit in a refinery are given below, including the pure-component liquid densities. Assuming an ideal-liquid solution (volume of mixing = 0), compute the liquid solution density in lb/ft?. Component M W Flowrate, lbmole/hr Liquid density, g/cm3 Propane 44 2.2 0.20 Isobutane 58 171.1 n-butane 226.6 0.43 0.40 58

Answer 1

& Mass flowrate [ 16l he ] = MW x Molas flowrate [Ismailho Mass lowrate [ ginr ] = mass Lowrate [Io/hr] x 453, 592_ ( 106 = 453. 592 gram) Mass flow rate of Propane = x 2.2 x 43907.706 458. 592 gihi → Mass flowlar of Isobutars : 58 x 17101 4501356.29 x 453. 592 glhr → Mass Luwrare of no butane - 58 x 226.6 x 435.592 5961498.938 galho → Total mass flowrate = 43907. 706 + 4501256. 29 + 5961 468. 938 = 10506732. 93 glhr Co) = Mass howrare Density voumetric flowrate u propane - = 219538. 53 colhe 43907, 706 0.2 V isobutane 4501356, 29 1125 3340, 73 on the 0.4 - 13863881.25 cm3/hr الدارمیا-م 5961468.938 0.43
