Abstract

Petroleum refineries are complex plants, and the combination and sequence of processes is usually very specific to the characteristics of the raw materials (crude oil) and the products. This industry generates wastewater effiuent containing oil, ammonia, sulphides, chlorides, phenols and other hydrocarbons. The most important pollutants are organics, oils, suspended solids and other toxic materials referred to as priority pollutants which be considered hazardous. Accidental discharges of large quantities of pollutants can occur as a result of abnormal operation in a refinery and potentially pose a major local environmental hazard. Previous studies have shown the reasonable performance of biological systems in refinery wastewater treatment. Thus, in this study an Upflow Anaerobic Sludge Blanket (UASB) was studied for treatment of wastewater from PETRONAS Penapisan Terengganu Sdn. Bhd. (PPTSB) at Kerteh, Terengganu. There are two reactors; A and B with total effective volume of 2.4 L for each reactor which were setup in parallel. Wastewater was continuously fed into the UASB reactors using a variable-speed peristaltic pump and seeded with the anaerobic sludge from a local Palm Oil Mill Effiuent (POME) anaerobic treatment plant. The steady state performance was evaluated under flowrate is 1.4 Lid and hydraulic retention time of l. 7 days. Both reactors were operated with different Volumetric Organic Loading Rate (VOLR) which was four in total in order to determine the optimum empirical parameters that lead to most efficient anaerobic treatment of petroleum refinery wastewater. Therefore, the kinetic analysis was used to analyze all the data gained from all the experiments conducted. The results show that the kinetic constant, K of Chemical Oxygen Demand (COD) data is 2.18 d· 1 • From the simulation, this research also found out that kinetic analysis give significant contribution.
