Vapor compression uses the highest form of energy, namely electrical energy. In absorption refrigeration, the energy input is any source of heat (e.g., electrical energy, bottled gas, kerosene, or solar energy).

Owing to the differing combustion characteristics and calorific values of the gaseous fuels which are commonly available [natural gas, liquefied petroleum (bottled) gas], slight variations in dimensions, including jet size and aeration controls, are necessary for maximum efficiency it is essential that, unless the burner is of the All Gases type which can be adjusted, the burner should be the one intended for the available gas supply. 

Explain why bottled gas containers are equipped with a relief valve. 

Methane is the major component of natural gas, while propane and butane are used as bottle-gas products. Research and compare the densities of methane, propane, and butane with that of air at STP. Which gas—natural gas or bottle-gas products—might you expect to rise in the air and which gas would you expect to settle to the ground ... 

As one more common example of liquid fuels present reference may be drawn to liquified petroleum gas (LPG) or bottled gas or refinery gas. This fuel is obtained as a by-product during the cracking of heavy oils or from natural gas. It is dehydrated, desulfurized and traces of odours organic sulfides (mercaptans) are added in order to identify whether a gas leak has occurred. Supply of LPG is carried out under pressure in containers under different trade names. It consists of hydrocarbons of great volatility such that they can occur in the gaseous state under atmospheric pressure, but are readily liquifiable under high pressures. The principal constituents of LPG are n-butane, iso-butane, butylene and propane,... 

The kitchen has an ancient bottled-gas stove, a Formica table with an oil lamp on it and a scatter of jewelry tools and materials, a tiled fireplace laid ready with raw-smelling coal, and a beautiful inlaid Queen Anne wall clock tocking away in the corner, showing the phases of the moon and the movement of the sun through the zodiac. As I head out of the back door and find the privy, a black shadow of a cat with blue eyes slips past my legs and away like warm smoke. 

About half the propane produced annually in the U.S. is used as a domestic and industrial fuel. When it is used as a fuel, propane is not separated from the related compounds, butane, ethane, and propylene. Butane, with boiling point -0.5 °C (31.1 °F), however, reduces somewhat the rate of evaporation of the liquid mixture. Propane forms a solid hydrate at low temperatures, and this causes great inconvenience when a blockage occurs in a natural-gas line. Propane is used also as so-called bottled gas, as a motor fuel, as a refrigerant, as a low-temperature solvent, and as a source of propylene and ethylene. 

They make up the most volatile portion of gasoline and are sometimes added to propane to be marketed as bottled gas. Most n-butane, however, is converted to butadiene, which is used to make synthetic rubber and latex paints. 

Fuel gas or refinery gas is produced in considerable quantities during the various refining processes and is used as fuel for the refinery itself and as an important feedstock for the petrochemical industry. Liquefied petroleum gas (LPG) is frequently used as domestic bottled gas for cooking and heating, and forms an important feedstock for the petrochemical industry. It is also used in industry for cutting metals.

Bottled gas was sold as early as 1810 in England, but propane was discovered at the start of the 20th century with the development of the natural gas industry. Problems in natural gas distribution were attributed to condensation of particular fractions of natural gas in pipes. This led to the removal of these higher boiling point gases and a search for applications for these gases. Concurrent with the development of the natural gas industry, society s... 

Gas fraction, boiling point up to 40°, contains normal and branched alkanes from Cj to C5. Natural gas is mainly methane and ethane. Bottled gas (liquefied petroleum gas) is mainly propane and butane. 

LPG (liquefied petroleum gas)— propane or (less commonly) butane, obtained by extraction from natural gas or from refinery processes. LPG has a vapor pressure sufficiently low to permit compression and storage in a liquid state at moderate pressures and normal ambient temperatures. Pressurized in metal bottles or tanks. LPG is easily handled and readily lends itself to a variety of applications as a fuel, refrigerant, and propellant in packaged aerosols. LPG is also called LP gas and bottled gas. See natural gas liquids.

The temperature of dry ice (sublimation temperature at normal pressure) is —109°F. Is this higher or lower than the temperature of boiling ethane (a component of bottled gas), which is —88°C ...

The installation of gas sensors to warn of gas leaks and the attendant risk of explosion is increasing in the developed world, especially in situations where bottled gas is stored, for example in caravans, trailers and boats. In the UK it is becoming commonplace to install them in homes along with smoke alarms. 

Nitric Oxide The ro-vibrational line selected for NO measurements is in the 1900 cm 1 region. Bottled gas of NO in Ne at a concentration of a few ppmv traceable to a National Bureau of Standards determination has been used as the calibration source for NO. The response time of the system for this gas is the residence time in the cell of 3 sec. The minimum detection limit MDC defined as a signal to noise of unity is better than 40 pptv (parts per 10ls by volume) for an integration time of 5 min fhe...

Alkanes are widely used as fuels Methane is familiar as natural gas, propane is used as bottled gas and as a fuel for welding torches, butane is used as cigarette lighter fluid, and octane is a major component in gasoline. 

You will be aware that North Sea gas consists mainly of methane. Propane and butane are used as bottled gas, camping gas or in cigarette lighters (when under pressure both propane and butane are liquids). Because the burning process gives out heat, the exothermic reaction is put to commercial use ... 

Natural gas contains, of course, only the more volatile alkanes, that is, those of low molecular weight it consists chiefly of methane and progressively smaller amounts of ethane, propane, and higher alkanes. For example, a sample taken from a pipeline supplied by a large number of Pennsylvania wells contained methane, ethane, and propane in the ratio of 12 2 1, with higher alkanes making up only 3% of the total. The propane-butane fraction is separated from the more volatile components by liquefaction, compressed into cylinders, and sold as bottled gas in areas not served by a gas utility.

A gas broiler is turned on in a closed kitchen whose volume is 35 m3. The oven burner produces 12,000 Btu/hr by burning bottled gas (mostly propane, C3H8, yielding approximately 20,000 Btu/lb). If the ventilation rate is 1.3 ACH, estimate (a) the steady-state C02 concentration in the kitchen, and (b) the C02 concentration in the kitchen hr after the broiler is turned on.

In this system, you can purge with an inert gas by evacuating the system (with a hand or motorized pump) and attaching a hose from one of the stopcock valves, to a two stage regulated bottle of inert gas. Fill the entire system at about two psi. A separate purge valve can be added to the system. Bottled gas can be purchased from any gas supplier such as Merriam-Graves and Pax Air.
