Spain

In Spain it is commonly called a butane cylinder and was introduced in the late 1950s. Usually a mixture of both gases is distributed, in a proportion of between 30% butane and 50% propane.

Butane gas, being easily liquefiable "Liquefaction (gases)"), is easy to keep in a pressure container, such as a cylinder. Each cylinder contains 12.5 kg of gas (159 kWh) and the total weight when fully filled is about 26 kg. They are distributed in trucks weekly through the streets, and taken to the houses by delivery boys, called butaneros, who also collect the previously used cylinder, now empty. When consumption is very low, it is more economical because you do not have to pay a monthly fee. This type of gas tank has the technical name: LPG UD-125,[4]​ it is produced by Repsol and there are companies specialized in the sale and installation.

If the cylinder is outside and the weather is cold, it may not supply enough gas even if it has not run out. This happens because the liquefied gas "Liquefaction (gases)") is cold and has a hard time evaporating, and can even freeze. When gas is consumed from the cylinder, part of the liquid gas evaporates and it cools even more, making the evaporation and exit of the gas even more difficult. This circumstance occurs especially when a lot of gas flow is demanded, for example, during the shower and when the cylinder is emptier, since when there is less liquid, the cold produced by the evaporation "Evaporation (physical)") of the gas is distributed among less liquid, causing the liquid to drop more in temperature than when it is fuller.

The butane cylinder can be used as a fuel source for automobiles, replacing liquid fuels such as gasoline, although natural gas is generally used. There are countries with restrictions or outright prohibitions for its use in vehicles.

Mexico

In Mexico it is called a gas tank or cylinder, commonly distributed by self-tankers known as "pipas". These supply cylinders of all capacities, as well as stationary tanks that range from 120 liters to 5,000 liters, (in industries there are installations that exceed 10,000 liters, in addition to supplying carburation gas plants, which have tanks of up to 25,000 liters).

In some places, portable tanks of different capacities are still used, a very common one is 20 kilos.

Nicaragua

In Nicaragua it is called a gas tank or cylinder, commonly distributed by self-tankers known as "cisternas". These supply cylinders of all capacities such as 10 Pound, 25 Pound "Pound (unit of mass)") and 100 Pound presentations. In addition to stationary tanks for businesses and industries that range from 80 liters to more than 5,000 liters, (in industries there are installations that exceed 10,000 liters, in addition to supplying carburation gas plants, which have tanks of up to 25,000 liters).

Gas is distributed in special vehicles, from bulk equipment distribution for businesses and industries, to tankers that distribute nationally throughout Nicaraguan territory to local distribution plants. In Nicaragua, the largest gas distributor at the level of homes, businesses and industries is Tropigas.
