(Texas A&M University. Libraries, 1993)A parameter control scheme is developed for control of a single-input single-output (SISO) process. An auto-recurrence model is used for the identification of structural and coefficient parameters. Adaptive model state ...
-
(Texas A&M University. Libraries, 1969)A model based on kinetic principles is developed for the adsorption of mixtures of gases in any number of layers by solid adsorbents. These models are hereafter referred to as the kinetic models. Equation of state which ...
-
(Texas A&M University. Libraries, 1993)Alkylation of isobutane with butene is an important industrial process for producing high-octane gasoline. Current industrial alkylations use either H2SO4 or HF as a catalyst. Compared to the liquid catalyst, the use of a ...
-
(Texas A&M University. Libraries, 1988)A functional transformation method has been developed to be used with different techniques for solving separation problems which are difficult to converge. Problems of this kind consist of sets of nonlinear equations with ...
-
(Texas A&M University. Libraries, 1970)The quasi-lattice solution model, primarily developed by Guggenheim but restated in a more concise mathematical notation by Barker, is applied to binary mixtures of saturated hydrocarbons. The model is applied to twenty-five ...
-
(Texas A&M University. Libraries, 1996)In this document, three problems were examined to enhance the understanding of transport phenomena related to interfacial phenomena. Each of these problems: (1) the effect of an external field on a fluid phase (supercritical ...
-
(Texas A&M University. Libraries, 1992)The present work is concerned with identifying the important parameters in bubble nucleation and growth and determining their effects on foam structures obtained by free expansion foaming. This work involves extending ...
-
(Texas A&M University. Libraries, 1989)An experimental apparatus, based on the Burnett mixing experiments, was designed and constructed for measuring the cross second virial coefficient (B12). In this isothermal experiment, two pure fluids are fed to separate ...
-
(Texas A&M University. Libraries, 1979)The recent demands on the avialable energy have stimulated the search for alternatives to oil. Methanol, because of its abundance and the availability of technology to produce it from coal, is projected as an alternative ...
-
(Texas A&M University. Libraries, 1992)Spray pyrolysis for ceramic powder preparation was studied, theoretically and experimentally. The forming mechanism for derived particles using air or argon as carrier was established based on the experimental results ...
-
(Texas A&M University. Libraries, 1986)The shape selectivity and catalytic properties of organically pillared zirconium phosphates, novel aluminophosphate (AlP12A), AlPO[4]-5 with transition metal oxides, and silicalite with transition metal oxides have been ...
-
(Texas A&M University. Libraries, 1988)The accurate prediction of phase equilibrium is vital to the modeling of many complex, multiphase reaction mixtures. Phase-equilibrium calculations for such mixtures often become computationally intensive due to the large ...
-
(Texas A&M University. Libraries, 1986)A new, continuously weighed pycnometer has been constructed for fast and accurate density measurements. This apparatus consists of a sample cell that is suspended from an electronic balance at all times. The sample cell ...
-
(Texas A&M University. Libraries, 1994)Recent amendments to the Clean Air Act have renewed interest in synthesizing isobutylene from coal derived synthesis gas for use in producing methyl tertiary-butyl ether. Previous work on isosynthesis was performed at ...
-
(Texas A&M University. Libraries, 1992)A combined Burnett-isochoric apparatus was designed and constructed to measure the pressure, density and temperature (P[rho]T) properties of corrosive fluids between 200 and 450 K to pressures of 21 MPa. Automated temperature ...

(Texas A&M University. Libraries, 1964)
-
(Texas A&M University. Libraries, 1994)Experimental temperatures and pressures were obtained using a Burnett-isochoric apparatus, and corresponding densitites derived for two mistures of carbon dioxide (1) and hydrogen sulfide (2); x1 = 0.7067, x2 = 0.2933 and ...
-
(Texas A&M University. Libraries, 1968)Experimental data were collected for a packed distillation column which was operating at a commercial natural gasoline plant. This column was packed with two-inch Pall Rings. The top section was three feet in diameter and ...
-
Development and application of NMRI for determining fluid saturation distributions in porous media (Texas A&M University. Libraries, 1995)Multiphase flow in porous media is an important subject in many fields of science and engineering, such as chemical engineering, petroleum engineering, soil mechanics, and groundwater hydrology. Fluid saturation is a ...
-
(Texas A&M University. Libraries, 1990)Equation of state calculations are used by engineers in all phases of chemical process design and control. New processes often are designed to operate under conditions for which insufficient experimental data exist, and ...
