Onsite thermal evaporation and treatment system for produced wastewater in oil and gas operations

Abstract

The present invention relates to a mobile thermal evaporation system for onsite produced wastewater treatment, designed to efficiently separate liquid and solid components while ensuring environmental compliance. The system comprises a thermal evaporation unit that exposes wastewater to high temperatures, inducing phase transition from liquid to vapor. A combustion system, including a burner, provides the necessary heat, operating on natural gas, flare gas, or liquid fuels while maintaining low emissions. The vaporized stream undergoes multi-stage filtration, incorporating a cyclonic separator and a high-efficiency ceramic filter to remove residual particulates before atmospheric discharge. A solids management system, including a rotary airlock and a screw conveyor, collects and transports solid residues for disposal or reuse. The system eliminates the need for deep well injection, reducing transportation costs, regulatory burdens, and environmental risks while enabling cost-effective, onsite wastewater treatment for the oil and gas industry and other industrial applications.
