EQUIPMENT DESIGN PROJECT ON DESIGN AN INVERTER FOR THE PRODUCTION OF 100000 METRIC TONES PER YEAR OF ETHANOL FROM SUGAR CANE

ABSTRACT
An equipment design project was carried out to design an inverter (Bioreator) or the production of 100,00 metric tones per year of ethanol from sugar cane. An inverter is a part of process equipment used in ethanol production from sugar cane.  While the rest process equipment include crusher, filter, centrifuge, fermented, distribution column and dehydrator. Having based on design on a steady –stated operation, the required feed rate and enthalpy in the inverter, calculated from material and energy balance are as follows:  Feed rate required; (Input)   Sugar  = 70.766kmol/hr  Water  = 13814.95kmol/hr  Invertabe = 106.149kmol/hr.  Output Stream;  Sugar = 141.531kmol/hr  Water  =13744.18kmol/hr  The Energy required = 17379.16mj/hr The required design data for the inverter is summarized as shown below; Volume of inverter required  = 910.969m/hr Diameter of inverter required = 8.31m Height of inverter required = 16.62m Type of Agitator required  = Turbine agitator  Liquid depth     = 14.603m Baffle plate width   = 0.83m Speed of Agitator    = 0 Diameter of Agitator  = 4.16m Power required for ungassed = 506 x 106watts Power required for gassed = 5.182 x 106watts Design Pressure   = 1.1atms Design Temperature   = 400C Permissible Stress   = 165N/M Wall thickness of inverter  = 6.55mm Commission Allowance   = 3.0 Number of Impeller   = 2 The detail information on the above datas can be traced on Appendix A, B. F and G. The success of this design project came as a result of collective efforts of some group members, although little difficulties were encountered.
