When it comes to versatile and efficient energy sources, LPG and propane emerge as key contenders. Similar in chemical composition and properties, these fuels are widely used for heating, cooking, fueling vehicles, and even powering industrial operations. Is liquified petroleum gas the same as propane, though? This guide unpacks the LPG vs. propane relationship, exploring their unique characteristics and the contexts in which they are most commonly used.

What Is LPG?

LPG, or liquified petroleum gas, is virtually a highly flammable and energy-rich mix of propane and butane. It can also contain minor admixtures such as propylene and butylene. By origin, LPG is a natural fuel, since it’s a product obtained during crude oil refinement or extraction of natural gas.

LPG can exist in both gaseous and liquid states, making it easy to store, transport, and use. Under normal atmospheric pressure, LPG is a gas, but when subjected to moderate pressure or low temperatures, it transforms into a liquid.

It’s a relatively clean fuel, producing fewer greenhouse gases and emitting less particulate matter when burning, as compared to other fossil fuels. At the same time, it offers high energy output that is fit for a range of residential and commercial applications.

What Is Propane?

Now let's look at what is propane gas. Propane is a hydrocarbon with the chemical formula C₃H₈. It’s a component of LPG derived when processing crude oil or natural gas. Existing as a gas under normal conditions, propane can be pressurized into liquid and compressed into cylinders or tanks for transportation virtually anywhere. Propane burns cleanly, generating minimal carbon emissions. It's also useful to know is natural gas renewable or nonrenewable to get a full impression of its advantages and disadvantages.

The uses of propane are extensive. In homes, it powers appliances like water heaters, stoves, and space heaters. For outdoor enthusiasts, propane is the fuel of choice for grills, RVs, and camping equipment. In commercial and industrial settings, propane is used to power forklifts and generators, and it is even used as a refrigerant in some systems.

Difference between LPG and Propane

Is LP gas the same as propane? While often mentioned together and sharing similarities, these two fuels are not identical. So, let’s see how propane vs. LPG compares in a few major aspects.

  • Composition: LPG is a broader category of liquefied gases primarily composed of propane and butane, while propane is a specific hydrocarbon that is often a major component of LPG.

  • Physical properties: The properties of LPG will vary depending on the content of the mix and which gas prevails. Propane, on the other hand, has a lower boiling point (–42°C/–44°F) and remains in a gaseous state even at very low temperatures.

  • Applications: Depending on composition, LPG is used for residential heating, cooking, and hot water systems, as well as in industrial applications and as a fuel for vehicles (autogas). Propane is preferred for outdoor use, such as camping stoves, BBQ grills, and heating in cold climates.

  • Storage and handling: Both LPG and propane are stored in pressurized tanks as liquids. Propane is also available in smaller portable cylinders.

  • Energy content: Both fuels pack 25 MJ/L.

The key difference between propane and LPG is that propane is a specific type of LPG, while the latter itself is a broader term encompassing a range of liquefied gases. Besides, the distinction between these two often depends on regional terminology and industry standards. Thus, in the US and Canada, propane is the primary form of LPG sold. However, in many European and Asian countries, LPG is a blend of propane and butane.

Advantages of LPG over Propane

Liquified petroleum gas vs. propane holds certain advantages that make it a preferred choice in specific scenarios.

  • Adaptable composition: A carefully formulated mix of propane, butane, and sometimes other hydrocarbons, LPG can be tailored for different applications and climates.

  • Cost efficiency: Butane, a common component of LPG, is often less expensive to produce and store. By blending butane with propane, suppliers can offer a more budget-friendly fuel option without compromising performance.

  • Energy density: Certain LPG blends can offer better energy efficiency, which is a benefit for applications where high energy density is critical.

  • Regional availability: In many parts of the world, LPG is more widely available than pure propane due to its versatility and adaptability, making it a reliable and efficient resource for residential, commercial, and industrial needs.

Advantages of Propane over LPG

Does LP mean propane? LP stands for liquified propane, often chosen over LPG blends for specific applications due to its distinct properties.

  • Consistency and purity: As a single hydrocarbon, propane is more predictable and reliable in performance.

  • Superior cold-weather performance: Propane vaporizes efficiently even in freezing climates, making it ideal for settings where low temperatures might hinder the efficiency of LPG blends.

  • Storage stability: As a pure formula, propane can be stored for extended periods without degradation, retaining its performance regardless of weather changes.

  • Lightweight and portable: It is often available in portable cylinders that are easier to handle and transport than bulkier LPG tanks, making propane an excellent choice for mobile use.

most frequently asked questions

1

What is SNG, and where is it applied?

Created with Pixso.
Synthetic Natural Gas (SNG) is a gas obtained by blending air with any gas or gas mixture, having a calorific value equal to the calorific value of methane. Information on blending Liquefied Petroleum Gas (LPG) with air is presented on our website. SNG is used to replace natural gas in industrial enterprises, gas power plants, and is applied for the gasification of settlements (cities, districts, villages). SNG can also be referred to as gas containing methane (CH4), obtained through coal gasification. Bio-SNG can be called gas containing methane, obtained through biomass gasification or biogas recovered from landfills, but bio-SNG can also be referred to as gas obtained in the process of blending bio-LPG with air.

What is the cost of SNG system and how to choose the equipment?

Created with Pixso.
To select the appropriate equipment and estimate costs, four main parameters need to be considered: 1. Maximum flow of SNG or natural gas per hour in normal cubic meters (Q = ? Nm3/h or MMBTU/h). 2. Gas pressure at the connection point (P = ? from 0.035 to 10 bar or from 0.5 to 145 psi). 3. Required calorific value of the gas (heat of combustion), for example, for natural gas 8,900 kcal/m3 (1000 BTU/Cu.Ft.), but some facilities in the European Union may use nitrogen-enriched gas, and its calorific value may be 5,260 kcal/m3 (22.0 Mj/m3). 4. Propane and butane ratios in LPG gas, for example, 60% propane and 40% butane. 5. The installation costs of SNG systems are several times lower than the installation costs of LNG for industrial enterprises. Please leave us your request on our website with the above-mentioned parameters, and we will send you an offer for connecting the SNG system.

(BioLPG) BioPropan, bioDME - what is it? Can BioLPG be used for transportation?

Created with Pixso.
BioLPG, also known as BioPropan, is a type of gaseous fuel that is identical in composition and chemical properties to traditional liquefied petroleum gas (LPG) but is produced from organic materials or waste. The BioLPG production process may involve processing various organic raw materials such as sewage sludge, agricultural residues, sawmill waste, and even bioethanol or the synthesis of renewable hydrogen and carbon dioxide. Currently, BioLPG finds practical application in gas supply systems in the United Kingdom. One of the interesting technologies is the production of DME, which stands for dimethyl ether, a gas similar to propane. DME can serve as both a finished product and an intermediate raw material for the production of biopropane. Its main source of production is the dehydration of methanol. Various raw materials are used for production, including biomass, waste, wood, agricultural products, as well as fossil fuels such as gas and coal. DME can be blended with LPG in proportions of 20% for household purposes (heating and cooking) and 25% - 30% for transportation purposes.
