Dry Cl gas refers to gaseous chlorine (Clâ‚‚) that is free from moisture or water vapor. Chlorine gas is typically a yellow-green gas at room temperature and is known for its strong, pungent odor. In various industrial applications, it is important for the chlorine gas to be dry to avoid reactions with moisture that could form corrosive hydrochloric acid (HCl) or other unwanted byproducts.
In practices such as water treatment, chlorine is often used for disinfection, and using a dry form can enhance efficiency. Dry chlorine gas can be produced and stored in pressurized containers, and it is important to handle it with care due to its toxic and corrosive nature. Safety precautions must be observed when working with chlorine to prevent exposure and potential health hazards.
