Abstract
A wastewater stream is flowed from a separator to an anode side of a microbial electrolysis cell (MEC). The wastewater stream includes water and hydrocarbons. The separator is positioned in a gas-oil separation plant. The MEC electrolyzes the hydrocarbons to produce hydrogen ions. A membrane separates the MEC into the anode side and a cathode side. The membrane allows the hydrogen ions and water molecules to pass through the membrane from the anode side to the cathode side, thereby forming a treated wastewater stream at the cathode side. The MEC combines the hydrogen ions at the cathode side to produce hydrogen gas. The treated wastewater stream and a hydrogen gas stream is discharged from the cathode side. The hydrogen gas stream includes the hydrogen gas produced by the MEC. The hydrogen gas stream is oxidized into water. Electrical power is generated in response to oxidizing the hydrogen gas into water.
