Hollow Fiber Membrane Modules for NOx Removal using a Mixture of NaClO3 and NaOH Solutions in the Shell Side as Absorbents

Nitrogen oxide (NOx) is one of the polluting gases harmful to humans and the environment. Nitrous oxide gas is mostly found in air, namely nitrogen monoxide (NO) and nitrogen dioxide (NO2). Nitrogen oxide gas in the air, which mostly comes from exhaust gases, needs to be reduced to minimize the...
