Bill. Please don't do this without a pressure relief on a vessel. Or at least don't make the container that is "solid" use a liquified gas with a low boiling pressure.
One ton Cl2 cylinders use very heavy walls. The ends are arched toward the product for security and strength. If you fail to leave a vapor space they bulge outward before the plugs fail. Not good.

Here's a chance to prove both. 1. Two containers of identical volume. One container 50% water, the other container 100% water. Each has been sitting in a 50 F room with the lid off. In other words the liquid and the containers are at 50F. Now make sure the 100% container is topped off and put lids on both. Read the pressure gage and satisfy yourself they both read "0". Move both containers into a 120 F room and come back when the two systems reach 120 F. 2. Same as above, but remove 10% of the water from the filled container before capping and moving. When the systems reach 120 F, which container has the higher pressure in each of the cases above? Bill Brooks William N. Brooks, P.E.
