(1) The minimum pressure required to liquefy a gas

(2) Neon, because it has such a low boiling point, doesn't liquefy with the other gases but hovers above the liquid air and can be removed.

(3) Another solution could be to liquefy the gas and pump it through existing oil pipelines.

(4) Air is first cooled to the point at which all of the gases in it liquefy (close to - 328u00d4u00f6u00bcu00d4u00fbu00e6F / - 200u00d4u00f6u00bcu00d4u00fbu00e6C).

(5) This point has never actually been achieved, since gases liquefy before they reach this temperature and they are no longer subject to the gas laws.

(6) The critical pressure is the amount of pressure required to liquefy water at the critical temperature.

(7) The industry is now converting large quantities of this gas to liquefied natural gas for export to energy-deficient countries, primarily in the Far East.

(8) A great deal of research has been done on the liquefaction of coal but with little success so far.

(9) Histologically, the lesions are characterized by a central of liquefactive necrosis with degenerating and necrotic liver cells and inflammatory cells.

(10) Additional findings during surgical exploration include the presence of liquefactive necrotic tissue and/or pus in between the fascial planes.

(11) A cavernous lesion is formed, characterized by progressive liquifactive necrosis and haemorrhage that oozes a foul-smelling liquid.

(12) An important milestone in the history of carbon monoxide came in 1877 when the French physicist Louis Paul Cailletet found a method for liquefying the gas.

(13) According to one scenario, coal would react with steam and oxygen before combustion to produce hydrogen and carbon dioxide, with the carbon dioxide liquefied and stored underground in deep aquifers or other geological formations.

(14) Under the initial contract, the two companies will each contribute US $500,000 for oil and liquefied natural gas exploration in the targeted area.

(15) Propellants are liquified gasses which have a low boiling point and vapor pressure high enough to expel the concentrate from the container.

(16) The aim of direct coal liquefaction is to break coal down into smaller component molecules, then to add hydrogen, creating lighter and more stable oil molecules.

(17) Virtually all ships from the Middle East carrying oil, liquefied petroleum gas or liquefied natural gas destined for Asia pass through the straits, according to Jane's Intelligence Review.

(18) The greatest demand for coal will be for electricity generation, but coal will continue to feature in conversion processes such as gasification, liquefaction , and pyrolysis, and in the production of metallurgical coke.

(19) He also liquefied carbon dioxide, hydrogen sulfide, and hydrogen bromide in a similar manner.

(20) In the process of liquefaction , solid coal is converted to a petroleum-like liquid that can be used as a fuel for motor vehicles and other applications.
