Based on the operating principle of a liquid jet ejector, gas scrubbers are an economical means of resolving problems caused by the harmful nature of exhaust gases by scrubbing, purifying, neutralizing and eliminating them almost entirely from smoke, together with polluting odors. In some cases, the gases are a too high  temperature and the scrubbing fluid can be used for cooling them

For the purification of gases having a strong smell, the scrubbing fluid has to include a chemical solution capable of interacting with the treated gas.
