ABSTRACT

The purpose of the project is to study the effect of liquid flow rate and gas flow rate on the pressure drop in a packed absorption tower and also to repair and restore the packed absorption tower to good working condition.

Trouble shooting revealed that the exit drain value was broken due to carelessness on the part of former user of the equipment. We had to carry out glassblowing operations using borosilicate glass to construct another value. Once this was done pressure build up within the tower was restored for absorption operation to take place.

A plot of log DO/H against log a superficial gas velocity gave 2.0774 2.3037 and 1.4940 respectively for slopes at varied superficial liquid velocity.

We concluded that increase in gas flow rate lead to increase in pressure drop since the graph obtained is linear. There was a drop in slope from lower liquid rate to higher as operation neared flooding condition. This means that industrially more cost is alluded to pumping operation to be successful.
