Abstract
A process of valorizing hydrocarbon- and/or organic matter-containing water streams by integrating oil-water separation technology that utilizes microbubbles and nanobubbles with supercritical water gasification technology. The integration of these synergistic technologies may be used to generate several streams of value from the hydrocarbon/organic matter containing water streams.
Claims20
A system for processing hydrocarbon and/or organic matter containing water streams, the system comprising:
- a microbubble generation unit in fluid communication with a diluted sludge source, the diluted sludge source comprising hydrocarbon and/or organic matter;
- a microbubble reaction and separation unit in fluid communication with the microbubble generation unit;
- an ozone generation unit;
- a nanobubble generation unit in fluid communication with the ozone generation unit;
- a nanobubble reaction and separation unit in fluid communication with the nanobubble generation unit;
- a heat exchange unit in fluid communication with the microbubble reaction and separation unit;
- a sludge dilution unit in fluid communication with the heat exchange unit;
- a salt separation unit in fluid communication with the sludge dilution unit;
- a gasification unit in fluid communication with the salt separation unit;
- and
- a nitrogen recovery unit in fluid communication with the gasification unit.

A method for processing a hydrocarbon- and/or organic-matter-containing water stream, the method comprising:
- introducing a diluted sludge comprising hydrocarbon and/or organic matter into a microbubble generation unit;
- generating microbubbles and contacting the diluted sludge with the microbubbles in a microbubble reaction and separation unit;
- separating, in the microbubble reaction and separation unit, the diluted sludge into a separated water stream and a concentrated sludge stream;
- providing a portion of the separated water stream to a heat-exchange unit;
- adjusting the concentrated sludge by combining the concentrated sludge stream with at least a portion of the separated water stream to form a water-adjusted concentrated sludge;
- separating salts and inorganic material from the water-adjusted concentrated sludge to form an enhanced treated feedstock;
- gasifying the enhanced treated feedstock in a gasification unit;
- recovering nitrogen from products of the gasification unit;
- directing at least a portion of the separated water stream to a nanobubble generation unit;
- generating ozone and providing the ozone into a nanobubble generation unit;
- generating nanobubbles and contacting the separated water stream with the nanobubbles in a nanobubble reaction and separation unit;
- and
- producing treated water having reduced chemical oxygen demand, salt content, and mineral content relative to the separated water stream.
