Black water treatment systems and methods
View Patent ↗A black water treatment system for a flow of black water. The black water treatment system may include one or more non-vacuum flash drums and a scrub-cooler. The scrub-cooler may include a water pathway with a nitrogen tube and a flow of nitrogen therein.
1. A black water treatment system for a flow of black water, comprising:
one or more non-vacuum flash drums; and
a scrub-cooler;
wherein the scrub-cooler comprises a water pathway with a nitrogen tube and a flow of nitrogen therein.
2. The black water treatment system of claim 1 , wherein the one or more non-vacuum flash drums comprise a high pressure flash drum.
3. The black water treatment system of claim 1 , wherein the one or more non-vacuum flash drums comprise an atmospheric pressure flash drum.
4. The black water treatment system of claim 1 , wherein the water pathway comprises a water entry port in communication with the one or more non-vacuum flash drums.
5. The black water treatment system of claim 1 , further comprising a gravity settler for separating a plurality of fines and flow of clear water therein and wherein the water pathway comprises a water exit port in communication with the gravity settler.
6. The black water treatment system of claim 1 , wherein the nitrogen tube comprises a plurality of tube apertures therein for the flow of nitrogen to pass into the water pathway.
7. The black water treatment system of claim 1 , wherein the scrub cooler comprises a cooling water jacket thereon for indirect cooling.
8. The black water treatment system of claim 7 , wherein the water jacket comprises a cooling water supply port and a cooling water exit port.
9. The black water treatment system of claim 1 , further comprising a scrubbed flow exiting the scrub-cooler.
10. The black water treatment system of claim 1 , wherein the scrub-cooler comprises a nitrogen vent.
11. The black water treatment system of claim 1 , wherein the scrub-cooler comprises an elongated shape.
12. A method of treating a flow of black water, comprising:
flashing the flow of black water to atmospheric pressure;
inserting a flow of nitrogen into the flow of black water to agitate the flow of black water and to strip dissolved gases in the flow of black water; and
indirectly cooling the flow of black water.
13. The method of claim 12 , further comprising flowing a scrubbed flow to a gravity settler.
14. The method of claim 13 , further comprising separating a plurality of fines and a flow of clear water in the gravity settler.
15. A black water treatment system for a flow of black water, comprising:
a high pressure flash drum;
an atmospheric pressure flash drum; and
a scrub-cooler;
wherein the scrub-cooler comprises a water pathway with a nitrogen tube and a flow of nitrogen therein.
16. The black water treatment system of claim 15 , wherein the water pathway comprises a water entry port in communication with the atmospheric pressure flash drum.
17. The black water treatment system of claim 15 , further comprising a gravity settler and wherein the water pathway comprises a water exit port in communication with the gravity settler.
18. The black water treatment system of claim 15 , wherein the nitrogen tube comprises a plurality of tube apertures therein for the flow of nitrogen to pass into the water pathway.
19. The black water treatment system of claim 15 , wherein the scrub cooler comprises a cooling water jacket thereon for indirect cooling.
