'at is te volume of !F7 to acieve at least 2= conversion of acetoneG "ased from te result, to acieve at least 2= conversion of acetone te volume of !F7 is =.= m +. Te flow rate of te feed is 1+<.< #gmole?r and te stream out is 11=.1H #gmole?r. Te lengt and diameter was adjusted until te conversion is 2=. From te table, te lengt is 1+.=1m and te diameter is .55cm.

Te objective of tis eperiment is to determine te volume, lengt, and diameter of te !F7 for desired conversion of product. $n tis eperiment, te desired conversion of acetone is 2=. $n order to get te 2= conversion, te lengt and diameter are adjusted. 'en te lengt and diameter were adjust, te flow of te feed and stream out of te product will cange significantly. Tus, te conversion can be determine from te flow of te feed and product by using e4uation. $n tis eperiment, to get te 2= conversion, te lengt is 1+.=1m and te diameter of te !F7 is .55cm. Te result also sow te volume of te !F7 wic is =.=m +. $n real situation, to build a !F7 reactor, a certain specification soud be follow. %n $CON software is a teoretically calculation in order to get te 1 st idea of manufacture of te reactor. % plug flow reactor !F7/ is a type of cemical reactor were te influent is pumped into te pipe. Cemical reactions occur troug te lengt of te !F7 and te reaction rate is not a constant. % conversion factor is a ratio or fraction/ wic represents te relationsip between two different units. % conversion factor is always e4ual to 1.
CONCL14/ON
%s conclusion, a desired conversion of a product can be acieve by adjusting te lengt and diameter of te !F7 reactor.
