BETTER OPERATION & ENERGY MANAGEMENT IN UREA PLANT

PROCESS CONTROL SYSTEMS

KEY PARAMETERS TO BE CONTROLLED ARE

•HP NH3 FEED TO REACTOR

•N/C MOLAR RATIO

•REACTOR CONVERSION PER PASS

•SPECIFIC STEAM CONSUMPTION

•1ST DECOMPOSER STEAM CONSUMPTION

• 1ST SEPARATOR TOP TRAY TEMP

•CARBAMATE CONCENTRATION ANALYSER SCALE READING

•INTERNAL WATER BALANCE CONTROL

•HYDROLYSER STRIPPER TOP TRAY TEMP

•HYDROLYSER STRIPPER FEED TRAY TEMP

•UREA RECYCLE
