“…Piezoelectric elements (164) are employed to measure pressure differences, and a range to 10,000 atmospheres is claimed for a free piston type manometer (151). A refractdmeter (135) can be used on liquids flowing under high pressure, and there is a high speed agitator (74,106) for pressure vessels. Tech., Oct.…”

T h e literature of the last file years and characteristic applications of high pressure are cited. A general trend tolrard the use of higher pressures in industrial operations is apparent. This involves principally the chemical industry, the petroleum industry, and the conversion of coal to liquid fuels. Developments in Germany are represented by such processes as coal hydrogenation, chemical production based on coal and acetylene, and the manufacture of nickel and iron carbonyl. In this country the demand for aviation gasoline and chemicals from petroleum as well as the new techniques for handling natural gas involve the use of higher pressures. Studies concerned with reaction kinetics, catalyst mechanism, and thermodynamics of reactions have a direct bearing on the use of high pressures. The importance of heat transfer, mass transfer, catalyst size, and gas flow conditions on the design of catalytic reactors is indicated. Much work has been done on the physical and thermal properties of pure compounds and their mixtures and on the phase equilibria of binary and multicomponent mixtures. Equipment for use at high pressures is noted.
