Abstract
The subject of maintenance optimization is not new, and many researchers have explored it. However, it is seen that one optimization solution cannot be used in all industries. Each industry and equipment thereof are unique as the product streams differ, layouts and operation variables, to name a few. However, Turnaround management is the most used strategy in petrochemical industries. Equipment downtime remains the biggest challenge; thus, the purpose of the study was to optimize the maintenance practices used on the critical electromechanical equipment in Sasol Synfuels Catalyst Preparation. The data from the Systems Applications and Products (SAP) was collected for each of the 13 electromechanical equipment identified in the catalyst preparation unit from the period of January 2016 to June 2021. An analysis and identification of the critical equipment within the unit were obtained using two different methods, namely the JADERI and AFEFY critical analysis approaches. Both methods include using qualitative and quantitative methods to obtain the results. From the use of the results obtained using both JADERI and AFEFY, the equipment was ranked. According to the JADERI approach, all the equipment was classified as noncritical, yet the AFEFY method classified the Arc furnace and Ball Mill equipment as being the most critical equipment. It is then followed by Kiln, who is categorized as the second most critical. The casting machine and conveyor belts are classified under category C, which dictates that they are the least critical equipment.
