UREA PLANT PROCESS AT G.S.F.C. LTD
INTRODUCTION
=> Urea was first synthetically in 1828 by wobler from ammonia and cyanuric acid and urea became the first organic compound prepared by synthesis from inorganic material.
=> The present method of synthesizing urea from NH3 & CO2 has been known in principle since 1968 but commercial production by this method started in 1922 in Germany & in 1932 in United state.
=> In India, at present there are about 28 urea plants having annual capacity of 21 million ton of urea.
PROPERTIES OF UREA

8. Bulk Density, gm / cm3 0.672
PRODUCTION PROCESS
=> All commercial production of urea is from CO2 and NH3 and the different method for Production of urea were adopted as follows :
• Once through process
• Partial recycle process
• Total recycle process
• Stripping process
• Partial recycle process
• Total recycle process
• Stripping process
Examples of different processes:
1. Mitsui Toatsu Total Recycle Process:
