A PROBABILITY BASED INSPECTION MODEL FOR A RANDOMLY FAIL EQUIPMENT IN A REFINING AND PETROCHEMICAL PLANT
Publication Date : 01/02/2009
Performance assessment of the Fuels Unit of a refinery has shown that soineequipment of the unit fail rand and failures are'detected by inspections. Current inspection schedules for these randomly failing equipment not based on any specifically established criteria. Sometimes inspection frequencies are high and other u inspections are very few in a period leading to undetected failures. A probability based method for obtai. optimal inspection schedule is proposed. The model recognizes the difficulties associated with quantifying costs of inspection and undetected failure generally and particularly in Manufacturing Plants in Nigeria while operating cost information is scarce and the general attitude to cost data is poor. The, failure record of 11F,AlE 1.0:W2 used to preheat Fluid Catalytic Cracking Unit (FCCU) feed to the reactor in Kaduna Relining Petrochemical Company Limited (K.R.P.C) is used for the inspection model.
