1. A waste container comprising:
one or more container side walls;
a container partition having a liner passing port, said container partition dividing said container into a waste chamber and a liner chamber, the liner chamber dimensioned to receive a plurality of sequentially linked liners, the container partition dimensioned to permit passage of at least one of the liners of the plurality of sequentially linked liners from the liner chamber to the waste chamber when the plurality of sequentially linked liners are received in the liner chamber;
a canister housing provided within the liner chamber;
a passageway for fluid communication between the waste chamber and the canister housing; and
a canister provided within the canister housing and having a pressurized fluid, the canister including a fluid discharge nozzle that discharges the fluid through the passageway and into the waste chamber as a spray or mist, the fluid discharge nozzle activated by a motion-sensing circuit,
wherein the motion-sensing circuit includes a movement sensor positioned proximate to the liner passing port in order to detect movement at or proximate to the liner passing port, and
wherein the motion-sensing circuit includes first and second temporizers, the first temporizer operable to transmit a first digital signal upon detection of movement by the movement sensor, the second temporizer operable to transmit a second digital signal upon an additional detection of movement by the movement sensor within a predetermined timeframe, the discharge of the fluid thereby occurring after the transmission of the second digital signal.
2. The waste container of claim 1, further comprising a motor and a trigger provided in the canister housing, the motor and trigger operable to open the fluid discharge nozzle upon activation by the motion sensing circuit.
3. The waste container of claim 1, wherein the liner chamber is detachable from the waste chamber.
4. The waste container of claim 1, said plurality of sequentially linked liners further comprising a stack of liners folded to at least partially overlap each other one to the next.
5. The waste container of claim 1, said plurality of sequentially linked liners further comprising a roll of liners connected one to the next and being separable along perforation tear lines.
6. The waste container of claim 1, wherein said liner chamber is positioned below said waste chamber.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for removing hydrogen sulfide from a hydrocarbon containing fluid comprises:
(A) contacting a methylmorpholine-N-oxide solution with the hydrocarbon containing fluid; and
(B) allowing the methylmorpholine-N-oxide to react with the hydrogen sulfide to remove the hydrogen sulfide, wherein the hydrogen sulfide is removed by oxidation, and wherein the oxidation of the hydrogen sulfide produces elemental sulfur.
2. The method of claim 1, wherein the methylmorpholine-N-oxide solution comprises methylmorpholine-N-oxide and water.
3. The method of claim 1, wherein the methylmorpholine-N-oxide solution comprises between about 1.0 wt. % methylmorpholine-N-oxide solution and about 60.0 wt. % methylmorpholine-N-oxide solution.
4. The method of claim 1, wherein the methylmorpholine-N-oxide reacts with the hydrogen sulfide in the presence of iron.
5. The method of claim 4, wherein the iron comprises a hydrated rust, a hydrated ferrous salt, or any combinations thereof.
6. The method of claim 1, further comprising adding heat to the methylmorpholine-N-oxide solution.
7. The method of claim 6, wherein the heat is provided by subterranean heat.

9. The method of claim 1, wherein the methylmorpholine-N-oxide solution is exposed to the hydrocarbon containing fluid from about 24 hours to about 48 hours.
10. The method of claim 1, wherein the hydrocarbon containing fluid comprises a gas.
11. The method of claim 1, wherein the hydrocarbon containing fluid comprises oil.
12. The method of claim 1, further comprising treating the elemental sulfur.
13. The method of claim 1, further comprising a mole ratio of methylmorpholine-N-oxide to hydrogen sulfide between about 1:1 and about 5:1.
14. The method of claim 1, further comprising a mole ratio of methylmorpholine-N-oxide to hydrogen sulfide between about 1:1 and about 3:1.
15. The method of claim 1, further comprising a mole ratio of methylmorpholine-N-oxide to hydrogen sulfide of about 2:1.
16. The method of claim 1, wherein adding the methylmorpholine-N-oxide solution to the hydrocarbon containing fluid comprises injecting the methylmorpholine-N-oxide solution downhole.
17. The method of claim 16, wherein the injecting comprises injecting the methylmorpholine-N-oxide solution with steam.
18. The method of claim 16, wherein the injecting comprises injecting into a drilling fluid.
