Abstract
Ergon Energy owns, operates, and maintains hundreds of substations of various capacities located throughout Queensland. These substations consist of various equipment required to maintain the electricity network that provides power for everyday consumption. The backbone of these substations is the transformer, traditionally liquid filled using high volume of mineral based oil for cooling and insulation. Any leakage, or catastrophic failure of this equipment would create significant risk to the environment.
This project focuses on the gravity oil water separation systems used by Ergon Energy to investigate the apparatus capability of fulfilling its designed function to the current hierarchy of Acts, Regulations, Codes of Practice, and standards for wastewater discharge.
The project considered different types of hydrocarbons contaminates found in the insulating oil and utilised a simulated rain event with a containment system mimicking a bunded area, and a U-tube to perform water quality testing for any hydrocarbons passing through the system. Testing was conducted for Benzene, Toluene, Ethylbenzene and Xylene (BTEX), Polyaromatic hydrocarbons (PAHs), total recoverable hydrocarbons and total petroleum hydrocarbon (TPH).
The results have indicated the U-tube is capable of minimising the concentrations of hydrocarbons at a set inflow rate, and keeping hydrocarbons within the target amounts on the outflow.
Further testing would be required to assess the separation systems capability when designed for different flow rates.
