Is Propane a Liquid or Gas?

It depends on the temperature and pressure surrounding it.

propane Cumberland County, PA Residents of Central or Southeastern Pennsylvania use propane in a variety of ways. Some power a grill or patio heater with a portable propane cylinder. Others rely on propane for home heating, hot water, cooking and other household needs. At Koppy’s Propane, we offer solutions for these kinds of households — and everything in between. We provide dependable propane delivery for homes that have stationary tanks — plus, we refill propane cylinders at our offices during business hours.

The Koppy’s team is also here to answer your questions about our fuel. A number of people have asked us, for example, which propane is called “liquid propane” in a container but burns in various appliances as a gas. Which is it?

Liquid or Gas?

Propane can transition from liquid to gaseous states quickly, depending on the temperatures and pressure around it.

Liquid propane’s boiling point — the temperature at which it becomes a gas —is incredibly low, roughly roughly -44°F. (By comparison, water’s boiling point is 212°F.) So, propane is almost always a gas at room temperature. However, propane can be kept as a liquid under high pressure when it’s sitting in a grill tank, a stationary home propane tank, a delivery vehicle or other closed container. How much pressure is required to compress propane into a liquid? In our trucks, the fuel is pressurized to about 150 pounds per square inch.

When a grill, furnace, water heater, gas range or other product needs to use propane, the pressure in the container is relieved. Some of the propane transitions to a gas, and it travels through a gas line to the appliance’s burner.

Propane vs. Natural Gas

Most U.S. propane is part of the same production pipeline as natural gas. Even so, they are considerably different fuels.

Propane is denser than air, and natural gas is lighter. Propane can be compressed and transported on roadways, railways and by sea. Natural gas is typically transported through the pipes. The primary component of natural gas is methane, a potent greenhouse gas. Propane contains no methane.

Where Does Propane Come From?

As mentioned in the prior section, most propane in the U.S. is a co-product of natural gas extraction, and some also comes as a co-product of oil refining. No additional wells need to be drilled to extract conventional propane.

An increasing amount of propane is renewable propane. Renewable propane is chemically identical to conventional propane, but it’s made from organic and recycled feedstocks and has a dramatically lower carbon impact. Renewable propane isn’t widely used in homes yet, but you can expect to see it in the future.
