Abstract
A plant for purifying a gas stream comprising at least 0.02% by volume of water, CO2 and NOx, comprising an adsorber characterized by: a cavity (1); an adsorbent (2) included in the cavity (1); an outer casing (3) made of carbon steel; an inner casing (4) made of stainless steel making a space having a width of between 10 and 100 mm between said inner casing and the outer casing, said space being at equal pressure with the cavity.
Claims11
A process for purifying a gas stream comprising, CO2, NOx, and at least 0.02% by volume of water, comprising using an adsorber, wherein said adsorber comprises:
- a cavity;
- an adsorbent included within the cavity;
- an outer casing made of carbon steel;
- an inner casing made of stainless steel, wherein a space between 10 and 100 mm wide is between said inner casing and the outer casing, said space being at equal pressure with the cavity, the process comprising subjecting the adsorber to a purification cycle comprising an adsorption step and a regeneration step using a regeneration gas and wherein nitric acid and liquid water are present in the adsorber during the regeneration step.
An apparatus for purifying a gas stream comprising CO2, NOx, and at least 0.02% by volume of water, comprising an adsorber, wherein said adsorber comprises:
- a cavity;
- an adsorbent included within the cavity;
- an outer casing made of carbon steel;
- an inner casing made of stainless steel, wherein a space between 10 and 100 mm wide is between said inner casing and the outer casing, said space being at equal pressure with the cavity.
