3.2 MAXIMUM LIQUID WITHDRAWAL RATE
The generally accepted alternate to manifolding ton con-
tainers is to withdraw liquid chlorine from the lower valve
and use an evaporator. By this means, a ton container can
be emptied in approximately five hours, which is equivalent
to 9600 lbs/24 hrs.
Liquid can be withdrawn from tank cars at up to nearly 8,000
pounds per hour, or 192,000 pounds per 24 hours.
3.2.1 MANIFOLDING FOR LIQUID WITHDRAWAL
WARNING: IN ACCORDANCE WITH CHLORINE INSTI-
TUTE RECOMMENDATIONS, DO NOT MANIFOLD TON
CONTAINERS FOR SIMULTANEOUS LIQUID CHLORINE
WITHDRAWAL. THIS MANIFOLDING CAN CAUSE OVER-
PRESSURIZATION AND RUPTURE.
3.3 CONTAINER VALVES
Standard cylinder and ton container valves are identical in
design, except that the cylinder valve includes a pressure
relief device. Cylinder valves are shown in Figure 3 and ton
container valves in Figure 4.
See Figure 5 for captive yoke type auxiliary container valves
(valve connection style #820, recognized by the Compressed
Gas Association as the only acceptable means of connecting
to container valves). The external threads on the container
valve are used only for securing the protective cap.
