| Abstract: | The original low interlock for flowrate at suction of HP ammonia pump in urea plant can open the reflux valve when suction flowrate is low to ensure the safety of pump,however,it can not meet certain operational requirement under some special case such as during the pump start-up procedure;the transformation of interlock from the two aspects of software,hardware is discussed. |
