Abstract

A discharge system includes a mixing vessel and a feedstock input in fluid communication with the mixing vessel. A solvent input is in fluid communication with the mixing vessel. A discharge output is in fluid communication with an outlet of the mixing vessel to discharge effluent. A method for generating turbulence on a liquid surface within a discharge system includes supplying a mixing vessel with feedstock fluid and solvent fluid to generate a liquid mixture and a gas pocket in the mixing vessel. The method includes supplying an impinging solvent fluid through a nozzle extending from a first end of the mixing vessel to generate a roiling surface at an interface between the gas pocket and the liquid mixture and permit uptake of gas from the gas pocket into the liquid mixture.

First claim

What is claimed is:

1. A discharge system, comprising:
a mixing vessel having a first side and a second side, defining a longitudinal axis therebetween;
a feedstock input in fluid communication with the mixing vessel;
a solvent input in fluid communication with the mixing vessel; and
a discharge output in fluid communication with an outlet of the mixing vessel to discharge effluent, wherein the solvent input includes two lines, wherein a first of the two lines defines a flow path to the mixing vessel through a nozzle extending from a first side of the mixing vessel into a cavity defined by the mixing vessel, and wherein a second of the two lines defines a flow path to the mixing vessel through an inlet through a sidewall of the mixing vessel, wherein a direction of the inlet is tangential to the sidewall of the mixing vessel at the inlet to introduce swirl to fluid in the mixing vessel, and wherein the nozzle is positioned above the feedstock input in a direction parallel to the longitudinal axis and the inlet is positioned below the feedstock input in a direction parallel to the longitudinal axis.

2. The discharge system of claim 1 , wherein the solvent input is in fluid communication with the nozzle to direct a solvent toward a gas pocket generated by gas entering with feedstock through the feedstock input.

3. The discharge system of claim 1 , wherein the inlet through the sidewall of the mixing vessel is on the second side of the mixing vessel.

4. The discharge system of claim 1 , wherein the two lines are downstream lines, wherein the solvent input includes a single line upstream from the two lines and includes a flow split orifice between the single line and the two lines.

5. The discharge system of claim 1 , wherein the second of the two lines is a diluent line.

6. The discharge system of claim 1 , further comprising a sparger operatively connected to an end of the feedstock input.

7. The discharge system of claim 6 , wherein the sparger extends from the end of the feedstock input into the cavity defined by the mixing vessel to direct incoming feedstock evenly toward the nozzle and the first side of the mixing vessel.

8. The discharge system of claim 1 , wherein the discharge output includes a flow restrictor downstream from the outlet of the mixing vessel.

9. The discharge system of claim 1 , wherein the mixing vessel defines the cavity between the first and second sides of the mixing vessel, wherein the mixing vessel includes packing material in the cavity for even flow of fluid throughout the mixing vessel.

10. The discharge system of claim 9 , wherein the packing material is defined between the solvent input and the discharge output.

11. The discharge system of claim 9 , wherein the packing material begins at a distance from the nozzle, measured along the longitudinal axis defined between the first and second sides of the mixing vessel, equal to one and one-half times a radius of the mixing vessel.

12. The discharge system of claim 9 , wherein the packing material extends through the mixing vessel along the longitudinal axis defined between the first and second sides of the mixing vessel a distance at least six times a radius of the mixing vessel.

13. The discharge system of claim 9 , wherein the mixing vessel includes a pair of perforated plates opposite from one another across the packing material.

14. The discharge system of claim 9 , further comprising a sparger operatively connected to an end of the feedstock input, wherein the sparger extends from the end of the feedstock input into the packing material.

15. The discharge system of claim 1 , wherein the mixing vessel has a larger diameter at a second end than at a first end.
