Abstract
In one embodiment, a black water processing system includes a vacuum pressure flash tank configured to separate gases from black water. The system also includes an ejector with a suction chamber and a nozzle. The suction chamber is coupled to the vacuum pressure flash tank, and the nozzle is configured to discharge a motive fluid across the suction chamber to create a vacuum within the vacuum pressure flash tank.
Claims20
A black water processing system, comprising:
- a vacuum pressure flash tank configured to separate gases from black water;
- and
- an ejector comprising a suction chamber and a nozzle, wherein the suction chamber is coupled to the vacuum pressure flash tank, and the nozzle is configured to discharge a motive fluid across the suction chamber to create a vacuum within the vacuum pressure flash tank.
A gasification system, comprising:
- a high-pressure flash tank configured to separate gases from black water to produce a first discharge of the black water and a second discharge of separated gases;
- and
- an ejector comprising a suction chamber and a nozzle, wherein the nozzle is configured to discharge the second discharge across the suction chamber to create a vacuum.
A gasification system, comprising:
- a gasifier configured to produce a synthetic gas and black water;
- a black water processing system comprising:
- a high-pressure flash tank configured to flash the black water to produce a first vapor discharge of first separated gases and a first liquid discharge of the black water;
- and
- a vacuum pressure flash tank configured to flash the black water to produce a second vapor discharge of second separated gases and a second liquid discharge of the black water;
- and
- an ejector comprising a suction chamber and a nozzle, wherein the suction chamber is coupled to the vacuum pressure flash tank, and the nozzle is configured to discharge the first vapor discharge across the suction chamber to pull the second vapor discharge into the ejector from the vacuum pressure flash tank.
