The inert gases are obtained by fractional distillation of air. For specialized applications, purified nitrogen gas may be produced by specialized generators on-site. They are often used aboard chemical tankers and product carriers (smaller vessels). Benchtop nitrogen generators are also available for laboratories.

Famous quotes containing the word production:
“From the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.”
—Charles Darwin (1809–1882)
“... if the production of any commodity necessitates the sacrifice of human life, society should do without that commodity, but it can not do without that life.”
—Emma Goldman (1869–1940)
“In the production of the necessaries of life Nature is ready enough to assist man.”
—Henry David Thoreau (1817–1862)
