ABSTRACT
In the majority field of chemical processes, the reactor vessel in which the reaction process take place is the key component of the equipment.The design of the reactors is very important to the success of the production. In this experiment, sodium hydroxide and ethyl acetate react in tubular flow reactor.Both of the reactants fed to the reactor at equimolar flowrate for a certain time.The reaction is carried out at different volumetric flowrate.The conductivity value of outlet stream is measured to determine the conversion achieve at different retention time. The retention time is highest for the lowest flowrate. The result shows that the conversion is increases as the residence time increases.
INTRODUCTION
Reactor is one of the most important parts in industrial sector. Reactor is equipment that changes the raw material to the product that we want. A good reactor will give a high production and economical. One of criteria to choose or to design a good reactor is to know the effectiveness of the reactor itself. There a many types of reactor depending on the nature of the feed materials and products. One of the most important we need to know in the various chemical reaction was the rate of the reaction. By studying the saponification reaction of ethyl acetate and sodium hydroxide to form sodium acetate in a batch and in a continuous stirred tank reactor, we can evaluate the rate data needed to design a production scale reactor. A stirred tank reactor (STR) may be operated either as a batch reactor or as a steady state flow reactor (CSTR). The key or main feature of this reactor is that mixing is complete so that properties such as temperature and concentration of the reaction mixture are uniform in all parts of the vessel. Material balance of a general chemical reaction described below.The conservation principle requires that the mass of species A in an element of reactor volume dV obeys the following statement:
(Rate of A into volume element) -
