Steady state distillation calculations: An investigation of computer techniques and an examination of results
This work has been divided into two parts. The first is concerned with methods of computation suitable for use with digital computers for distillation problems with one feed and two product streams. Two methods were ...
Vapor-liquid equilibria in the system hydrogen-nitrogen-carbon monoxide
Vapor-liquid equilibrium compositions for the system hydrogen-nitrogen-carbon monoxide were determined at -310°F, and -280°F and -240°F from 300 psig to the critical. PVT data for hydrogen were fitted to the ...
Effects of the decay of sulfur-35 on some electrical properties of cadmium sulfide semiconducting films
The vacuum behavior of radioactive and non-radioactive semiconducting films of CdS has been studied as a function of time in order to determine the effect of radioactive doping. Radioactive films containing S35 were made ...
Low temperature vapor-liquid equilibrium in light hydrocarbon mixtures: Methane-ethane-propane system
Experimental equilibrium data have been determined for 175 mixtures of methane, ethane, and propane. The investigation included temperatures from 50°F to -200°F and pressures up to the critical. A vapor recycle ...
A study of alumina silicon fluoride combinations as hydrocarbon conversion catalysts
The purpose of this work was to study the influence of certain variables in the preparation of an alumina-silicon-fluoride complex on its behavior as a cracking catalyst.
Influence of pyrolysis conditions on macropore structure of char particles
A systematic analysis of the structure of char particles produced from an Illinois #6 coal was carried out. Coal particles were pyrolyzed in a hot-stage reactor under inert (N$\sb2$) and reactive (5% O$\sb2$ / 95% N$\sb2$) ...
Derivation of an infinite-dilution activity coefficient model and application to two-component vapor-liquid equilibria data
Infinite-dilution fugacity coefficients were obtained for the binary system fluorene/phenanthrene at thirteen temperatures by fitting total pressure across the entire mole fraction range by a computer routine. A thermodynamically ...
Heat transfer during condensation inside a horizontal tube
Heat transfer data were taken for methanol and Freon-12 condensing inside a horizontal tube over considerable ranges of pressure, temperature driving force, liquid loading, and vapor velocity. A single mechanism for heat ...
