CENTRIFUGAL , SCREW OR .... 2

[lomli]

HI

I AM A BEGINNER PROCESS ENGINEER, AND I HAVE TO DESIGN A SIMPLE SYSTEM TO POOR AND DRAIN OIL FROM THE HOT OIL LOOP.

THIS SYSTEM WILL BE USED IN CASE OF SIMPLE SHUTDONWN OF THE UNIT FOR MAINTENANCE IN THIS CASE OIL WILL BE AT AMBIANT TEPERATURE.

THE SYSTEM CAN BE USED ALSO IN EMERGENCY CASES OIL WILL BE THEN TRANSFERD BY THIS SYSTEM AT THE TEMPERATURE OF THE LOOP WICH IS ABOUT 190 °C.

FOR THIS SYSTEM WHICH KIND OF PUMPS IS RECOMANDED KNWING THAT THE MAX FLOWRATE IS ABOUT 200 M3/H AND PRESSURE JUST TO TRANSFER THE OIL TO AN OTHER TANK LOCATED AT ABOUT 150 MTERES.

THANK YOU VERY MUCH

The high flow and the low pressure favors a centrifugal pump. A triple screw pump is an option too but for sure more expensive.

Agree, centrifugal pumps and if needed for emergency situations, it might be a good idea to install a multi-pump installation - maybe 3x50% units - this will give you 1 unit as a standby in case of failure of 1 unit and some flexibility to run either 1 or 2 units to suit the operation.

hi ,

1- about pump selection, pump with these parameters should be centrifugal pump .
2- regarding economical wise . one pump is enough if this pump working only for sometimes and emergency cases. it means if required maintenance you can proceed at stop time.
