reagent injection

Reagent injection

Acid gases (SOx, HCL, HF) generated by certain industrial processes (such as waste incineration) can be neutralised by the introduction of alkaline reagents to the flow of fumes, which generally refer to sodium bicarbonate or to calcium hydroxide.
By rule of thumb, the injection of the reagent takes place at a pneumatic level starting from the dosing system and carried as far as a static mixer located in a reactor or in a fume duct.

The dosing systems must guarantee the injection of the reagents with the correct concentrations and in the selected points, in order to facilitate the correct removal of the acid components present in the fumes.
In fact, the inhalation of such contaminants could cause serious damage to the environment and to the health of the operators, leading to the onset of temporary disorders, such as migraine, asthma, cough and skin irritations, but also permanent disorders, such as pulmonary pathologies and malignant tumours .
