Abstract
A method for separating undesired components from gas mixtures comprises the following steps of providing a gas mixture containing at least two gaseous components, wherein one component is an undesired component, feeding water to the gas mixture, forming a hydrate of the undesired component and a remaining gas mixture, wherein the hydrate is formed by spraying a combination comprising the water and the gas mixture, and separating the hydrate from the remaining gas mixture.
Claims10
A method for separating undesired components from gas mixtures comprising the following steps:
- providing a gas mixture containing at least two gaseous components, wherein one component is an undesired component,
- feeding water to the gas mixture,
- forming a hydrate of the undesired component and a remaining gas mixture, wherein the hydrate is formed by spraying a combination comprising the water and the gas mixture, and
- separating the hydrate from the remaining gas mixture.
Method according to any of the preceding claims wherein the undesired compound is H2S.
Method according to any of the preceding claims wherein the undesired compound forms 30 vol.-% or more of the gas mixture.
Method according to any of the preceding claims wherein the hydrate is formed by spraying a combination comprising the water and the gas mixture through a nozzle.
Method according to any of the preceding claims wherein the hydrate is formed by spraying a combination comprising the water, the gas mixture and tetrahydrofuran.
