The increase in demand of residue due to new production of Group III Lube Base Oil Product in Melaka Refinery required the residue plant to increase the feeding capacity of residue to the required unit. For the plant to achieve the targeted flow rate of the residue, the residue plant has upgraded the existing pumping capacity and cooling capacity by installing one unit of centrifugal pump P1112C and one unit of air fin cooler E1129A to support the existing cooling system for the tempered water. The analyses are focusing on the mathematical modelling of the pump and heat exchanger to determine the right specification for the new equipments that are required for the new operating design. The hydraulic work covered the pipelines system from crude column C1101 to storage tank T72211 in order to determine the total head losses along the pipelines and through the equipments connected along the loop. The head of pump and pump-system operating curve at different operating capacity Q has been plotted to determine the operating point for the pump. For thermal capacity analysis of heat exchanger, ratio (old design/new design) for coolant flow has been determined. The analysis for air fin cooler E1129 and E1129A involves some calculations on the internal tube side and also finned tube side.
