Apparatus for purifying wet gas streams containing co2 and nox

Abstract

The invention relates to a device for purifying a gas stream comprising at least 0.02% by volume of water, CO2 and NOX, the device comprising an adsorber, characterized in that the adsorber comprises: a cavity ( 1); the adsorbent (2), which is contained in the cavity (1); the carbon steel outer shell (3); the stainless steel inner shell (4), formed between said inner shell and said outer shell A spatial gap between 10 and 100 mm in width, wherein the spatial gap is equal to the pressure at which the cavity is subjected.

Description

technical field [0001] The invention relates to a method for purifying CO containing 2 and NO X Apparatus for wet gas flow and relates to a purification process employing the apparatus. [0002] The term "wet gas" is understood to mean a gas having a relative humidity of greater than 30%, preferably greater than 80%, more preferably saturated with water under operating conditions, or even supersaturated, since the gas may contain entrained liquid water particles . [0003] The term "contains CO 2 " is understood to mean more than 20 mol%, preferably more than 50 mol%, more preferably more than 80 mol% of CO 2 content. [0004] The term "contains NO X "Understand to mean NO X (or nitric acid) content greater than or equal to 10ppm (by mole), preferably greater than 100ppm. Background technique [0005] To reduce the amount of CO emitted by humans into the atmosphere 2 emissions, developed to capture the CO produced in a given process 2 craft. Extraction of CO from ...

AI Technical Summary

Problems solved by technology

However, it is difficult to be really sure that a part of the casing will not be subject to corrosion (advancement of the front associated with aging of the sorbent, modification of operating conditions, entrainment of liquid water, etc.)

So partial plating will not be 100% fail safe
