Nitrogen oxides are formed in combustion and also during some reactions involving metals and acids. The treatment approach used depends on the gas temperature, the NOx concentration, and the relative proportions of the different nitrogen oxides (NO, NO2, N2O4, N2O2, N2O3, etc.) present. Through partner companies, we can offer de-NOx systems to the process industries as follows:
It is well known that NO is not especially soluble, and NO2 can be reduced in the scrubbing liquor to form NO, which is then released from the scrubbing solution back into the gas stream, limiting the stage capture efficiency. ERG can offer treatment of chemically generated NOx using a combination of gas-phase oxidation with ClO2 or ozone, followed by multi-stage scrubbing. By employing V-tex® technology, it is possible to generate an effluent stream from the process with sufficiently high concentration salts (NaNO2) to make it suitable for recycling and re-use in the client’s process. See our application brochure or talk to our process sales team about how we can help.
