Chlorine valve outlet connections

Chlorine is authorized for shipment in ton containers with 2000-lb (907-kg) capacity that comply with DOT specification 106A500X. The pressure relief device is a fusible plug. These are installed on each end of the container. Ton containers conforming to older specifications may still be used. Valve outlet connections are the same as for cylinders except the ton container... 

The standard valve outlet connection for chlorine cylinders in the United States and Canada is Connection CGA 820. The limited... 

The two-phase process stream goes to a receiver that also serves as a phase separator. The liquefied chlorine leaves through a bottom connection. The uncondensed gas, containing some of the chlorine along with the noncondensable impurities, goes overhead. A valve on the outlet line maintains the desired pressure on the gas in the liquefier and also serves to control the discharge pressure of the chlorine compressor. The combination of the pressure and temperature on the process side of the liquefier determines the extent to which the chlorine can condense (see Achievable Degree of Liquefaction, below).
