IN his preface Prof. Young says that he wrote this book in the hope that the solution of the difficulties of fractional distillation might be rendered easier. He has written an eminently practical ...
IF YOU thought the Higgs boson was elusive, consider the case of dark matter. The Higgs—the particle that gives other subatomic species mass—was predicted in 1964 but actually nabbed only last ...
In this video, Fran Scott explains fractional distillation - the separation of crude oil into fractions. Crude oil is a finite resource; petrol and other fuels are produced from it using ...
Fractional distillation is rarely used anymore. Almost all fuel “refining” is done with Catalytic Crackers. Not unlike the catalytic converter in a car breaking down unburned gasoline, ...

A. H. PRICE has published1 a table of values of vapour pressure of tritiated water. As these values differed greatly from our previous results, based on enrichment experiments of tritiated water ...
Fractional-distillation facilities are typically located near major industrial facilities in urban areas. Because pharmaceutical manufacturing is labor intensive, many facilities are located in lower ...
