From a one-ton chlorine cylinder, which valve releases gaseous chlorine?

The top valve on a one-ton chlorine cylinder is designed to release gaseous chlorine. This design is specifically intended for the safe handling and operation of chlorine gas. As chlorine gas is lighter than liquid chlorine, it naturally accumulates at the top of the cylinder. Therefore, when the top valve is opened, the gaseous chlorine can be effectively released and utilized.

The bottom valve, on the other hand, is typically used to access the liquid chlorine within the cylinder. When this valve is opened, liquid chlorine can be drawn out, which can be dangerous if not handled properly. The side valve may also serve various functions, but it is not designated for the release of gaseous chlorine. The safety valve is intended for pressure relief and is a vital feature for preventing over-pressurization within the cylinder, not for normal gas release. Understanding these specific functions helps ensure safe practices when working with chlorine cylinders.
