CHAPTER I: INTRODUCTION 1.1 Background Protein (the root word from the Greek protos, meaning "the ultimate") is a complex organic compounds of high molecular weight polymer of a monomer-monomer amino acids linked together by peptide bonds. Protein molecules containing carbon, hydrogen, oxygen, nitrogen and sometimes sulfur and phosphorus. Protein plays an important role in the structure and function of all living cells and viruses.

Synthesis section  In this section urea is made from carbon dioxide gas, liquid ammonia, and the solution karbamat byrecycle. The main tool is the synthesis reactor (DC-101) of the vessel upright on the operating temperature of 195 0C and pressure of 200 kg/cm2. This reactor provides sufficient volume to conduct the reaction of urea synthesis, as close as close to the equilibrium reaction. According to the design capacity,...
