What are liquefiable gases?

(xxix) “liquefiable gas” means a gas that may be liquefied by pressure at -10oC but will be completely vaporised when in equilibrium with normal atmospheric pressure (760 mm.

What is used for liquifying of gas?

Liquefied chlorine is transported for eventual solution in water, after which it is used for water purification, sanitation of industrial waste, sewage and swimming pools, bleaching of pulp and textiles and manufacture of carbon tetrachloride, glycol and numerous other organic compounds as well as phosgene gas.

What is Linde’s method?

(i) Linde’s method : This process is based upon Joule-Thomson effect which states that “When a gas is allowed to expand adiabatically from a region of high pressure to a region of extremely low pressure, it is accompained by cooling.”

Is it possible to liquify a gas at any condition?

at a temperature above critical temperature and pressure below critical pressure. Liquefaction of gases takes place at a temperature either equal to critical temperature or at a temperature lower than critical temperature.

What does the liquefaction of a gas mean?

Liquefaction of gases is physical conversion of a gas into a liquid state (condensation).

Can a gas be liquefied under high pressure?

After more research on this relationship it was found that the high temperature isotherms is similar to that of ideal gas but still under high pressure the gas cannot be liquefied. When the temperature of the gas is decreased then the curve shows deviation from the ideal one.

How big is the volume of liquefied natural gas?

Liquefied natural gas (LNG) is natural gas that has been cooled to a liquid state (liquefied), at about -260° Fahrenheit, for shipping and storage. The volume of natural gas in its liquid state is about 600 times smaller than its volume in its gaseous state in a natural gas pipeline.

When to use liquefied natural gas for electricity?

In the United States, some power plants make and store LNG onsite to generate electricity when electricity demand is high, such as during cold and hot weather, or when pipeline delivery capacity is constrained or insufficient to meet increased demand for natural gas by other consumers. This process is called peak shaving.
