Definitions
- the present invention relates to a process for purifying a gas stream comprising nitric oxide NO and NOx nitrogen oxides by a purification unit with conversion of nitric oxide on a catalytic bed, prior to said purification.
- Nitrogen oxides are pollutants commonly emitted during the combustion of fossil fuels. NOx in the atmosphere creates tropospheric ozone, which is toxic when inhaled. In addition, NOx contributes to the formation of acid rain, which is detrimental to plant and animal life, as well as property. During the treatment and purification stages, especially compression (followed by refrigeration), the NOx will generate acidic condensates, in particular: nitric acid, nitrous, ...
- cryogenic separation by distilling combustion fumes rich in CO 2 comprising nitrogen oxides (NOx) in which the nitrogen oxides whose oxidation is greater than that of NO are separated from the fumes.
- NOx nitrogen oxides
- SNCR selective non-catalytic reduction
- SCR selective catalytic reduction
- the NH 3 -containing gas then passes through a multi-bed catalyst in a temperature range of between 250 and 380 ° C.
- the most frequently used catalysts are supported metal oxides TiO 2 or Al 2 O 3.
- a solution of the invention is a device for removing nitrogen monoxide NO and NOx oxides with x> 1 from a gas stream comprising:
- a catalytic bed enabling the conversion of at least a portion of the NOx to NOx with x> 1, and an NOx abatement unit with x> 1, the catalytic bed being situated upstream of the abatement unit. and the abatement unit being a cryogenic separation unit.
- the device according to the invention may comprise one or other of the following characteristics: the catalytic bed allows the conversion of at least 60% of the NOx to NOx with x> 1, preferably from minus 80%, more preferably at least 90%, the catalytic bed is a bed of silica gel;
- the catalytic bed is a bed of sulfur-doped activated carbon
- the catalytic bed is a sulfur-doped alumina bed.
- the subject of the present invention is also a process for the removal of nitrogen monoxide NO and NOx oxides with x> 1 from a gaseous flow, implementing a device according to one of claims 1 to 5 and wherein the gas stream is contacted with the catalyst bed so as to convert at least a portion of the NO to NOx with x> 1 before entering the NOx abatement unit with x> 1.
- the conversion rate of nitric oxide is between 25 and 100%, preferably between 50 and 100% conversion, more preferably between 80 and 100%.
- the method according to the invention may have one or other of the following characteristics:
- the gaseous flow is a flow of combustion fumes
- the conversion of NO to NOx with x> 1 is carried out at a temperature of between 5 and 150 ° C., preferably between 5 and 120 ° C., more preferably between and at 50 ° C. and / or at a pressure comprised between between 1.3 and 100 bar abs;
- the contact time of the gas stream with the catalytic bed is less than 120 seconds, preferably less than 40 seconds.
- Contact time means the ratio of the volume of the catalytic bed to the volume flow rate of the gas stream to be purified.
- the catalytic bed associated with the NOx abatement unit makes it possible to stop the nitrogen oxides both in the form of NO and in the form of NOx (x> 1).
- the gas will be further purified of its nitrogen oxide content that the NO to NOx conversion (x> 1) has been advanced upstream of the NOx abatement unit. And the removal of NOx from the gas will be even more incomplete as the amount of nitric oxide entering the NOx abatement unit will be large.
- NO and 200 ppm NO 2 is contacted with a 150 cm catalytic bed composed of silica gel particles at a pressure of 30 bar and a temperature of 10 0 C and a flow rate of 35 NL / min.
- the gas composition at the outlet of the catalytic bed is measured and the degree of conversion of NO to NO 2 obtained is 90%. Thus, only about 80 ppm, or 8% of the total NOx, are still in NO form once the catalyst bed is crossed.
- the initial NO 2 and NO 2 formed by NO oxidation can be removed from the gas stream by an NOx abatement unit.
- NO is brought into contact with a catalytic bed of 150 cm 3 composed of sulfur-doped activated carbon particles, at a pressure of 5 bar and a temperature of 120 ° C. and with a flow rate of 15
- the NO 2 formed can be removed from the gas stream by a NOx abatement unit.
