Abstract

Catalytic reforming unit is practiced extensively in the petroleum refining industry to convert gasoline boiling-range low-octane hydrocarbons to high-octane gasoline compounds for use as high-performance gasoline fuel. This is accomplished by conversion of n-paraffins and naphthenes in naphtha to iso-paraffins and aromatics over bifunctional catalysts. Petronas Penapisan Terengganu Sdn Bhd employed two catalytic reformer units that are in Kerteh Refinery-1 (KR1) and Kerteh Refmery-2 (KR2) respectively. This project will focused mainly on catalytic reformer unit located at Kerteh Refinery-1 as it is more concern on the requirement of standard for research octanenumber, RON. The data from the unit is used to test the correlation for prediction of LPG and reformate yield. The correlation used is provided by HPI Consultant. The process correlation for catalytic reforming estimates the product yields and reformates properties for reforming full boiling range naphtha. Moreover, the correlation have some variables that can be changes such that pressure required in the unit, research octane number (RON), napthene content plus 2 times the aromatic content of feedstock (N2A) and specific gravityof the feed. This will help the studyon the catalytic reformerunit in refinery such as Petronas Penapisan Terengganu Sdn Bhd to evaluate and model the unit. The correlations givenare the standard or the benchmark for the typical production of LPG and reformate. By then, the actual data from the plant or the unit needed to compare both of them and analysis need to be done to extract the information. In the same time, the fundamental of the unit must be understood thoroughly as from the feedstock to the product yield. Moreover, each step of the process has different operating capabilities such as endothermic or exothermic reactions which are then why the temperature are slightly decreasing and from the process there is a burner which can counteract and maintain the temperature along the process. This fundamental of understanding the process in catalytic reformer is important as to justify of those data coming from the plantor the correlation is valid. Moreimportantly, the otherthroughput of the project is to model the catalytic reforming unit in Petronas Penapisan Terengganu Sdn Bhd using the correlation from HPI Consultant so that the requirement of LPG and reformate yield are met. iii
