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 . The company was formed in 1935, and is one of the UK's largest suppliers of liquefied petroleum gas (LPG).
LPG is composed mainly of propane and butane, while natural gas is composed of the lighter methane and ethane. LPG, vaporised and at atmospheric pressure, has a higher calorific value (46 MJ/m 3 equivalent to 12.8 kWh/m 3 ) than natural gas (methane) (38 MJ/m 3 equivalent to 10.6 kWh/m 3 ), which means that LPG cannot simply be substituted for ...
Normal high pressure gas cylinders will hold gas at pressures from 200 to 400 bars (3,000 to 6,000 psi). An ideal gas pressurised to 200 bar in a cylinder would contain 200 times as much as the volume of the cylinder at atmospheric pressure, but real gases will contain less than that by a few percent. At higher pressures, the shortfall is greater.

Campingaz, formerly Camping Gaz, is a brand of products with compressed, mixed butane/propane [1] gas supplied in small, lightweight, disposable canisters and larger, refillable cylinders [2] designed for use as a fuel while camping and caravanning. The fuel gas is compressed to a liquid and sold in characteristic blue metal containers.
The cost to convert a vehicle to propane in Canada is approximately CA$4,000 to CA$6,000 for the current vapour or liquid fuel injected technology, and fleet users can expect a payback on the conversion cost within a year. Converting a vehicle to propane is approximately half the cost of converting a vehicle to natural gas in Canada.
Gas flares were common sights in oilfields and at refineries. U.S. natural gas prices were relatively stable at around (2006 US) $30/Mcm in both the 1930s and the 1960s. Prices reached a low of around (2006 US) $17/Mcm in the late 1940s, when more than 20 percent of the natural gas being withdrawn from U.S. reserves was vented or flared.
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.
