Gas Scrubbing is the process of removing a gaseous pollutant from the gas stream.

It’s usually used in industrial desulfurization and denitrification, such as marine gas desulfurization, power plants gas denitrification, steel factory gas desulfurization and so on.

Gas Scrubbing Applications

As the improvement of people’s environmental awareness, more and more rules be deployed in the marine industry, gas scrubbing is one of them.

Engineering considerations for gas scrubber nozzles

Different designs of scrubber will require different types of nozzles and spray properties to operate effectively. The key engineering considerations to be made when selecting nozzles for gas scrubbing applications are listed in the blue menu to the right hand side of this page.  Below this, through the grey menu, details on the different designs of suitable gas scrubbing nozzle are accessible.

The information contained in both the engineering considerations pages and the nozzle designs pages is summarised in the “Gas scrubbing nozzle cheat sheet” which is accessed by the orange button also to the right hand side of this page.

Nozzle Selection

A variety of nozzles are suitable for gas scrubbing applications. For packed bed scrubbers TF spiral nozzles can give very wide distribution patterns with up to 170 degree spray angles. TF nozzles are also useful in absorber spray scrubbers as they produce sprays with good levels of atomisation.
