PLANT LIFE

(OP)
HOW  PLANT LIFE FOR DIFFERENT CHEMICAL PLANTS CALCULATED? CAN YOU OPERATE A PLANT AFTER ITS DESIGN LIFE OR PLANT LIFE? IF POSSIBLE WHAT STEPS ARE TO BE TAKEN?

RE: PLANT LIFE

Hi 023 ,

Normally refineries and chemical plants ,operatiing life is taken as 20 years,when making feasibility studies,that is about 5% depreciation on equipment cost .
These values can be found in Process Plant Economics,by Peters& Timmerhaus- McGraw-Hill.
Real times,will depend on maintenance procedures,and some refineries have been operating for over 50 years! ,with high maintenance cost,and  is more feasible to the owner than buying a new plant.

Regards,

Whylie
