CHAPTER I INTRODUCTION 1.1 HISTORY: Ethylene Glycol (1‚ 2 – ethanediol)‚ HOCH2CH2OH usually called glycol is the simplest Diol. Diethylene glycol and Triethylene glycol are Oligomers of Mono ethylene glycol. Ethylene glycol was first prepared by Wurtz in 1859; treatment of 1‚2 dibromoethane with silver acetate yielding ethylene glycol diacetate via saponification with potassium hydroxide and in

A REPORT ON AUTOMATION OF CONVERTOR TILTING DRIVE USING PLC AND VVVF DRIVES Abstract: Industry is a home of various kinds of machines that are used for numerous processes and treatments. The control and working of these machines have been automated through the use of PLCs. Automation has resulted in faster production rate‚ increased accuracy‚ better quality and reduced faults and human errors. PLCs and VVVF drives are used in most of the sections and units at VISL because of their simple methods
