Butane is a gas at atmospheric pressure and room temperature. In the fuel tanks of cigarette lighters, butane welding torches, and most other butane powered heating devices, butane has been compressed to the point that it remains liquid at room temperature. When the trigger of these devices is depressed, a valve opens, allowing butane to escape from the tank, and in doing so, it's pressure drops to atmospheric pressure, and the liquid butane escaping the tank rapidly boils and becomes a gas, which is ignited by an ignition source. Strictly speaking, if the tank contained pure butane, when all the butane has evaporated, all that would be left in the tank is butane gas at atmospheric pressure. If you sprayed liquid butane on your table, and it were completely pure, the liquid would evaporate, leaving nothing behind. In reality, butane fuel is not completely pure, and may contain small amounts of all sorts of contaminants, some of which can be left behind after the butane evaporates. Some of these contaminants like methane, ethane, and propane likely would evaporate away with the butane, but other contaminants, like trace amounts of other petroleum distillates will likely remain after the butane evaporates.
Butane will only stay a liquid under pressure. NORMAL lighters keep it in a sealed container so it only evaporates when the trigger is pressed. Zippo lighters are NOT sealed and even if they had a way to inject butane, it would all flow out the top. Zippos require a fuel that is a liquid at room temp and evaporates a little at a time so the sparks will ignite the gas. Zippo does produce a special butane lighter, however.
Butane gas is a liquid in lighters because it is under high pressure, which allows it to remain in a liquid state at room temperature. However, when released into water, the pressure decreases and the butane evaporates into a gas due to its low boiling point.
The salt will remain in the container as it does not evaporate with the water. So, all the 20 grams of salt will be left behind after the water evaporates.
The duration of butane fuel can vary depending on usage, but a standard small canister may last for a few hours of continuous use on a portable stove. It's recommended to keep track of usage and have backup canisters available for longer trips or extended cooking needs.
I have observed salts being left behind when water evaporates in situations such as saltwater pools, when seawater evaporates to form salt flats, and in kitchen settings when liquid from marinades evaporates, leaving salt residue behind.
The temperature of liquid butane sprayed into the air will rapidly decrease as it expands and evaporates, causing it to cool down. This process is known as evaporative cooling, where the liquid absorbs heat from the surroundings in order to transform into a gas.

The salt is left behind.

Several minerals are left behind when water evaporates.
Salt Crystals
Precipitation causes dissolved substances to be left behind to form minerals after water in lakes or ponds evaporates.
