Characterization of Produced Water from Petroleum Hydrocarbons Terminal

Abstract

Produced water (PW) is the largest by product of oil and gas extraction. It contains both organic and inorganic components that can harm the environment. However, the PW contents are different according to the area it is produced. There are a few factors that can affect the content compositions such as type of reservoir, geographic location of field, geologic formation, type of hydrocarbon being produced and lifetime of the proposed reservoir. This study analyses the contents via PW characterization which has been collected from five different sampling points from a petroleum hydrocarbon terminal. The characterization conducted includes pH, turbidity, salinity, total suspended solid (TSS), total dissolved solid (TDS), chemical oxygen demand (COD), biochemical oxygen demand (BOD), dissolved oxygen (DO), total oil and grease (TOG), polycyclic aromatic hydrocarbon (PAHs) analysis and MP-AES test which is to study the  element content in the PW. Results shows that the PW characteristic of each PW samples varies based on different sampling point. PW samples with higher amount of oil content affect others characteristic of the sample. Most of the samples were found not meeting the standard of EQA1974.
