As you use the tank, the pressure inside goes down. As the pressure drops, the temperature also drops because of something called the Ideal Gas Law (see the "Ideal Gas Law" Related Questions linked the left of this answer). Ice forms on the tank because water moisture in the atmosphere is condensed on the cold tank and then frozen.

How do you recover propane from a used propane tanks?

Most of the time propane can be pumped from a tank. As long as there is a liquid port on the tank. The problem with getting a refund or credit for the propane is almost never worth it. This operation will need a propane bobtail and uselly a second truck with a vapor pump (used to raise the pressure in the tank and force it into the truck) Only qualified people can preform this task. A propane company will only pump a tank if it has a problem that has become a safety issue. Cost involved for the dealer two people two trucks, (time and mileage) Two hours minimum. Remember the dealer has already incurred the cost of the delivery so your not going to get a full refund.


Does cold affect propane?

Yes and no. Propane is very nonreactive by itself (except when burned in oxygen). The temperature that propane is at doesn't effect it's properties. Also, propane has a very low freezing point (-188°C) so it won't freeze when it gets cold. However, when using propane for a stove, etc., cold can affect how well it works. A propane tank is full of liquid propane under pressure. When it is being used, the liquid first has to vaporize to a gas, where it can then be burned. Because it takes a lot of heat for the liquid to vaporize into a gas, cold weather can slow down the flow. If this is a problem, the propane tank can be placed in a bucket of lukewarm water so that heat is available for the propane to vaporize.

That is not a very clear question. Are you asking if the materials left in a propane tank could be toxic if you use the tank for water?

An old propane tank can contain a significant amount of hydrocarbons, usually in the gasoline and diesel boiling point range.

How long will a 30000 btu convection heater last on a 20lb tank?

The MH80CV, part of the Mr. Heater Contractor Series, is a 30,000-80,000 BTU Propane Convection heater. The MH80CV provides reliable heat for areas up to 1900 sq. feet. It will operate for up to 14 hours on a 20-lb propane tank. The MH80CV features a standing pilot, piezo push-button ignition, and 'insta-lock' chamber for easy assembly. The MH80CV comes ready to use with the included hose and regulator. It operates on a 20-lb or larger propane tank (not included).There are a couple of other factors that may effect the time a 20 pound cylinder will last on a heater. Propane is stored in liquid form in the tank and must evaporate to be used in most heaters. The colder the temperature the propane tank is stored at the lower the pressure is in the tank. As the liquid propane evaporates it cools down the liquid propane still in the tank. As a result at minus -20 you might have a half full twenty pound tank and not have enough pressure to run the heater.
