Abstract

Production activities in the oil and gas industry can cause environmental pollution, one of which is soil pollution. Soil contamination is generally found in the refinery area caused by oil spills or pipe leaks, loading and unloading, and oil transportation. In this study, oil-contaminated soil is processed by extracting the oil contained in the ground using water. The treatment process was applied to oil-contaminated soil, sandy soil, and mud, with a processing time of 30 to 120 minutes and flow rates of 46, 90, 139, and 183 mL/minute. The temperature of the water used for processing is ±175°C with a pressure of 14.5 atm. The results showed that the average reduction in oil content in oil-contaminated samples, namely soil, sandy soil, and mud, was 37.7%, 5.8%, and 88.4%, respectively. This method is most suitable for waste soil contaminated with dirt. Based on the flow rate and processing time, the longer the processing time, the less oil content in the oil-contaminated soil waste, and the more oil is produced. This oil recovery system on waste soil contaminated with oil can save a budget of up to 1.1 million rupiahs per tonne.
