Not to be confused with Liquefied natural gas.
LPG minibuses in Hong Kong
Liquefied petroleum gas or liquid petroleum gas (LPG or LP gas), also
referred to as simply propane or butane, are flammable mixtures of
hydrocarbon gases used as fuel in heating appliances, cooking equipment, and
It is increasingly used as an aerosol propellant and a refrigerant[citation
needed], replacing chlorofluorocarbons in an effort to reduce damage to the
ozone layer. When specifically used as a vehicle fuel it is often referred
to as autogas.
Varieties of LPG bought and sold include mixes that are primarily propane (C
3H 8), primarily butane (C 4H 10) and, most commonly, mixes including both
propane and butane. In the northern hemisphere winter, the mixes contain
more propane, while in summer, they contain more butane. In the United
States, primarily two grades of LPG are sold: commercial propane and HD-5.
These specifications are published by the Gas Processors Association
(GPA) and the American Society of Testing and Materials (ASTM).
Propane/butane blends are also listed in these specifications.

What does buses in Hong Kong have to do with this:

Butane is used for domestic heating and cooking
same goes for bots and campers and not the Propane.
I know of people using propane for heating, WH, cooking. I see
people here with problems relating to propane for that. I see
people complaining about the cost of propane. I see propane
trucks driving down the highway. I see propane used for all the
home outdoor grills that run off tanks. Butane? It exists in the
world of camping and comes in little cans. Home use, for
heating/cooking, maybe somewhere, by somebody, but it's surely
I don't know, Tony. Answer that question for yourself.
I had my propane fuel licence for automotive propane years ago.
I've also used both propane and butane torches.
I've also lived where butane was the common "bottled gas" - and we
never had freezing temperatures.
Good luck starting a butane heater when it's 10 degees F. No problem
NOT the same as Propane.
Although propane is more popular, butane continues to be used as a
fuel source. It is used as a fuel in stoves, cigarette lighters and
even in aerosol sprays as a propellant. Besides, butane is cheaper
than propane, but comparatively, it is more difficult to use, so it is
not very commonly available and not many gadgets, devices are designed
to be used with butane as fuel source.
But you should know that butane is more efficient than propane when
used as fuel. If same volume of butane and propane is burned at
temperature above freezing, butane will end up providing 12% more
energy than propane. Thus, butane can be the preferred choice when it
is available in adequate amounts since it is energy-efficient and also
has an advantage of cheaper price.
Unlike butane, propane is available more easily in small portable
tanks and is used widely for heating houses. It is used as a fuel in
gas barbeques, lanterns and camping stoves. Automobiles run on
liquefied petroleum gas or LPG which is made by mixing propane with
other fuels like butylene, propylene or butane.
When the fuel needs to be stored for a long time, propane is a better
choice than butane. It stores well in variable weather conditions and
even below freezing temperature will not affect the storage conditions
of propane because of its propetries. When people need to go camping,
hiking or mountain climbing, especially in cold weather, propane is
preferred over butane as a fuel for cooking. Since propane gas is
odorless, leaks are harder to detect. For this reason, ethanethiol is
mixed with propane so that leaks can be easily detected.
Butane, C4H10, boils at 30.2F,
Propane, C3H8. boils at -43.6F.

I know all too well that a butane cigarette lighter will not light when

Another thing about those lighters. NEVER let one fall down the defrost
vent opening on the dashboard. When the heater gets hot enough, the
lighters literally explode. More than once I was driving and suddenly
there's a loud bang, and chunks of plastic are flying all over the car.
Talk about having a panic attack. Especially the first time it happened.
There was never any flame, but it's still frightening. Fortunatly it

I wont happen again, I fastened a piece of 1/4" hardware cloth (screen)

While on the subject of vents and screens, most of the condensing
furnaces around here have either no screen on the intake and exhaust
pipes or at most a very rough one, eg 1/2" openings. I have a Rheem
and the install manual specifically says not to place any kind of
screen on the openings. I think they are probably worried about
them freezing up, icing over. But you would think that it would
raise all kinds of problems, eg mice or similar deciding to take
up residence in the pipes or worse, the furnace during summer.
