1 Division of Engineering Assessed Report Department of Chemical Engineering EH1SPF: Gas Absorption ina packed column To pleted by student Student Name Student ID Group number Date of experiment Date submitted Office use only Grade awarded Penalty Final grade Markers Signature 2 Abstract Packed tower is well known as one of the most wildly used method in absorption zone to separate different gas by liquid phase. In this experiment, the aim is to calculate the overall liquid transfer coefficient Kxa by the equation The value of Kxa in three groups are changeable and only two of which can work out Kxa value. The Kxa value of group 2 and group 3 is and . In addition, both the Kxa value is below 1 so that log (Kxa) is always negative. Moreover, the G and HoL have a positive linear , G and Kxa have a negative relationship, so does Kxa and three diagrams illustrate that the gas flow rate has negative influence on the efficiency of gas absorption. And the height ofa transfer unit also has an inverse ratio to the efficiency. 3 Content Abstract ................................................................................................................................................ 2 Content ................................................................................................................................................. 3 Objectives ............................................................................................................................................ 4 Introduction ........................................................................................................................................ 4 Background theory ........................................................................................................................... 5 Apparatus ............................................................................................................................................ 7 Procedur
