Abstract
A formulation for preventing or reducing the effect of impurities contained in the carbon dioxide of a carbon dioxide pipeline. The formulation can include an additive that can adsorb, absorb, react with, complex with, or bind with impurities in the carbon dioxide pipelines to render the impurity in another form, compound, or otherwise unavailable for interaction with the pipeline materials. The additive can be a dehydrating agent, an oxygen scavenger, a hydrogen sulfide scavenger, a sulfur oxides removal agent, a nitrogen oxides removal agent, or combinations thereof.
Claims20
A method comprising:
- introducing a formulation comprising an additive to a carbon dioxide pipeline comprising carbon dioxide,
- wherein the additive comprises a dehydrating agent, an oxygen scavenger, a hydrogen sulfide scavenger, a sulfur oxides removal agent, a nitrogen oxides removal agent, or combinations thereof.
A formulation comprising an additive for a carbon dioxide pipeline, wherein the additive comprises a dehydrating agent, an oxygen scavenger, a hydrogen sulfide scavenger, a sulfur oxides removal agent, a nitrogen oxides removal agent, or combinations thereof.
A carbon dioxide pipeline comprising:
- a pipeline;
- carbon dioxide contained in the pipeline;
- and
- a formulation comprising an additive for the carbon dioxide contained in the pipeline, wherein the additive comprises a dehydrating agent, an oxygen scavenger, a hydrogen sulfide scavenger, a sulfur oxides removal agent, a nitrogen oxides removal agent, or combinations thereof.
A system comprising:
- a pipeline containing carbon dioxide and an impurity;
- and
- an impurity removal unit coupled to the pipeline, wherein the impurity removal unit receives at last a portion of the carbon dioxide from a first location on the pipeline, removes the impurity or converts the impurity to a compound that can be removed by the impurity removal unit, and sends an impurity depleted carbon dioxide to a second location on the pipeline that is downstream of the first location.
