Excerpt from Transactions of the American Institute of Chemical Engineers, Vol. 13: Part II, 1920-21 Sulphur plays a more basic role in chemical industry than any other element. Either as elementary sulphur or combined as a metallic sulphide, it is the source of all sulphuric acid. Hence any changes in the sulphur industry Should be of great interest to the chemical engineering profession. America now dominates the sulphur industry and virtually all the American sulphur is produced by three companies - viz., the Union Sulphur Co., the Freeport Sulphur co. And the Texas Gulf Sulphur Co. These three companies produce not only virtually all the sulphur used in the United States but also a considerable surplus which is exported. The only other sulphur which normally enters the American market in quantity comes from Japan1 and its per centage calculated on the consumption of the United States is small and is not likely to increase. Rising costs of living have meant much higher wages in Japan, as well as in other parts Of the world; in fact, the percentage increase has probably been greatest in Japan, due not only to world conditions affecting all countries but to the rising standards of living of the Japanese. These facts, together with present higher transportation costs, will make it increasingly difficult for Japanese sulphur to compete on our Pacific Coast with the American product.

Excerpt from Transactions of the American Institute of Chemical Engineers, Vol. 14: 1921-22 Sulphuric acid is universally concentrated by the application of heat. The first interest of the designer of apparatus to concentrate sulphuric acid must hence lie in the thermal properties of sulphuric acid. Several articles have been written on this subject, and one of them at least has treated the subject very thoroughly and comprehensively. The results, however, are not most conveniently expressed, and the original article is not particularly accessible. This, then, must be the excuse for the present attempt to present an old subject from a different viewpoint. The first thermal property of sulphuric acid which interests us is its specific heat.
