Propane is a three-carbon alkane with the molecular formula C3H8. It is a gas at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation. Discovered in 1857 by the French chemist Marcellin Berthelot, it became commercially available in the US by 1911. Propane is one of a group of liquefied petroleum gases. The others include propylene, butane, butylene, butadiene, isobutylene, and mixtures thereof. Propane has lower volumetric energy density, but higher gravimetric energy density and burns more cleanly than gasoline and coal.
A compressed-air car is a compressed-air vehicle powered by pressure vessels filled with compressed air. It is propelled by the release and expansion of the air within a motor adapted to compressed air. The car might be powered solely by air, or combined with other fuels such as gasoline, diesel, or an electric plant with regenerative braking.
Liquefied petroleum gas is a fuel gas which contains a flammable mixture of hydrocarbon gases, specifically propane, propylene, butylene, isobutane, and n-butane.
BOC Ltd is a British based multinational, industrial gas company, more commonly known as BOC, now a part of Linde plc. In September 2005, BOC had over 30,000 employees on six continents, with sales of over £10.6 billion. BOC was a constituent of the FTSE 100 Index and the FT 30. On 5 September 2006 the BOC Group became part of the Linde Group of Germany.
A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.
A compressed-air vehicle (CAV) is a transport mechanism fueled by tanks of pressurized atmospheric gas and propelled by the release and expansion of the gas within a pneumatic motor.
Bottled gas is a term used for substances which are gaseous at standard temperature and pressure (STP) and have been compressed and stored in carbon steel, stainless steel, aluminum, or composite containers known as gas cylinders.
A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure. High-pressure gas cylinders are also called bottles. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid, supercritical fluid, or dissolved in a substrate material, depending on the physical characteristics of the contents. A typical gas cylinder design is elongated, standing upright on a flattened bottom end, with the valve and fitting at the top for connecting to the receiving apparatus.
Industrial gases are the gaseous materials that are manufactured for use in industry. The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders. The industry producing these gases is also known as industrial gas, which is seen as also encompassing the supply of equipment and technology to produce and use the gases. Their production is a part of the wider chemical Industry.
An icemaker, ice generator, or ice machine may refer to either a consumer device for making ice, found inside a home freezer; a stand-alone appliance for making ice, or an industrial machine for making ice on a large scale. The term "ice machine" usually refers to the stand-alone appliance.
A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.
Calor is a brand of bottled butane and propane which is available in Britain and Ireland. It comes in cylinders, which have a special gas regulator.
Storage tanks are containers that hold liquids, compressed gases or mediums used for the short- or long-term storage of heat or cold. The term can be used for reservoirs, and for manufactured containers. The usage of the word tank for reservoirs is uncommon in American English but is moderately common in British English. In other countries, the term tends to refer only to artificial containers.
Oxy-fuel welding and oxy-fuel cutting are processes that use fuel gases and oxygen to weld or cut metals. French engineers Edmond Fouché and Charles Picard became the first to develop oxygen-acetylene welding in 1903. Pure oxygen, instead of air, is used to increase the flame temperature to allow localized melting of the workpiece material in a room environment. A common propane/air flame burns at about 2,250 K, a propane/oxygen flame burns at about 2,526 K, an oxyhydrogen flame burns at 3,073 K and an acetylene/oxygen flame burns at about 3,773 K.
The ROTAREX Group is a privately owned Luxembourgish group of companies who develop and manufacture high pressure valves, tube fittings and pressure regulators for almost all types of gas, in almost all application fields. Founded in 1922, under the name CEODEUX in Lintgen, Luxembourg, ROTAREX currently employs approximately 1600 people and is present on all continents with a broad range of products.
Bernzomatic is an American manufacturing company. It was founded by Otto Bernz in 1876 in Newark, New Jersey as Otto Bernz Co.. The company manufactures handheld torches and accessories, especially gas burner torches using fuel cylinders containing butane, propane, MAPP gas, and oxygen for soldering, brazing, and welding. Its trademark torch packs include Basic Use, Multi-Application, and Specialty. Its products include torches, fuel cylinders, kits, solders and accessories, and utility lighters.
A cryogenic gas plant is an industrial facility that creates molecular oxygen, molecular nitrogen, argon, krypton, helium, and xenon at relatively high purity. As air is made up of nitrogen, the most common gas in the atmosphere, at 78%, with oxygen at 19%, and argon at 1%, with trace gasses making up the rest, cryogenic gas plants separate air inside a distillation column at cryogenic temperatures to produce high purity gasses such as argon, nitrogen, oxygen, and many more with 1 ppm or less impurities. The process is based on the general theory of the Hampson-Linde cycle of air separation, which was invented by Carl von Linde in 1895.
The Horton sphere is a spherical pressure vessel, which is used for storage of compressed gases such as propane, liquefied petroleum gas or butane in a liquid gas stage.
A. O. Smith Corporation is an American manufacturer of both residential and commercial water heaters and boilers, and the largest manufacturer and marketer of water heaters in North America. It also supplies water treatment and water purification products in the Asian market. The company has 27 locations worldwide, including five manufacturing facilities in North America, as well as plants in Bengaluru in India, Nanjing in China and Veldhoven in The Netherlands.
Several types of valve connections for propane, butane, and LPG containers exist for transport and storage, sometimes with overlapping usage and applications, and there are major differences in usage between different countries. Even within a single country more than one type can be in use for a specific application. This requires adequate tooling and adapters for replenishment in multiple countries. For example for overlanders and users of autogas traveling with a container originating in one country to other parts of the world this is a major concern. This article describes existing standards and the standards in use for a number of countries. For disposable containers the availability per country is described. Filling stations may be able and allowed to fill foreign containers if adequate adapters are available. Adapters are provided by, amongst others, camping stores. The iOverlander database maintained by travelers, My LPG and the Facebook group "Cooking Gas Around the World" provide more information about individual sources per country. Much general information about global LPG use and standardization is available from the World LPG Association and the AEGPL
