There are two symmetrical spiral flows in the horizontal epitaxial reactor at ordinary operating condition. The pitch length of the spiral flow is or of the important factors which prescribe for the characteristics of fluid flow in that reactor.
In this study, the experimental equation for the estimation of the pitch length is obtained.
In order to obtaine the pitch length, information about the bulk gas temperature in that reactor is necessary. The relation between the bulk gas temperature and the operating condition is also obtained experimentally.

An experimental study was carried out on the vapor hold up and boiling heat transfer coefficients of pure liquids (H
2O, MeOH) and binary mixtures (l0mol% McOH-H
2O, 50mol% McOH-H
2O, H
2O-C
12H
25C
6H
4 SO
3Na (1.00g/l)).
Those data were measured by the use of natural circulation vertical tube evaporator (four different annular spaces).
Distribu tions of vapor hold up and boiling he transfer coefficients were measured for different heat flux (from 2, 150 kcal/m2-hr to 40, 100 kcal/m
2·hr). Vapor hold up was correlated with the heat flux length of boiling region and modified terminal velocity of a single bubble by the use of vapor void function defined by Eq. (10).
Furthermore, boiling h eat transfer coefficients were well correlated by the use of vapor hold up and a dimensionless experimental equation was obtained.

Method of calculations for nonisothermal gas a sorbers in which absorption of a single solute, vaporization or condensation of solvent, and sensible-heat transfer between the gas and the liquid, all taking place simultaneously, have been proposed by Sherwood and Pigford who described a step-by-step porcedure, Mizushina and his coworkers who described a graphical method, and another a few workers.
However, in all of these methods, th e mass and heat transfer resistances of the liquid phase are ignored.
This paper presents a graphical method of calculations for nonisothermal gas absorbers in which the mass and heat transfer resistances of the gas and liquid phases are accounted, and moreover a method of the utilization of digital computer for this calculation and an illustration for the application of this method.

Thermal decomposition of pr opane was carried out in the argon plasma jet reactor. The spectroscopic measurement of the jet flame was made to obtain the information about temperature and mixing of propane with the argon jet flame. The experimental results suggested that the mixing rate of propane with the jet flame was relatively fast and that there was sharp distribution of temperature in the plasma jet reactor in the radial and axial directions. On the basis of these facts, a new model of the plasma jet reactor was proposed. The experimental relationship between the conversion of propane and the specific energy was fairly well explained by this model.

To afford a mathematical to ol for filter-press operation, the internal mechanisms of filtration in plateand-frame press are investigated, and the basic differential equation for the period to be termed filter-consolidating are derived.
On the basis of the approximate solution of the basic equation, the flow rate equation of filtrate for the filter-consolidating are presented in terms of the thickness and the radius of filter-chamber, and the coefficient of consolidation which depends on the filtration pressure and the properties of slurry materials. The variations of flow rate with time compare favorably with experimental results obtained by using nine kinds of filter-chambers.
It is emphasized that the filtration processes of industrial filter-press can be well analysed by dividing into two parts of the filtration and the filter-consolidating period.

Both the carbonization proce ss and the activation process are necessary to make activated carbon from coal. This paper is concerned with the effect of the tower diameter of fluidized beds on conversion of oxygen in carbonization process.
The coal was carbonized in the several fluid-beds (105, 300, 500 and 800 mm in diameter). The fluidizing gas was air. Since it was impossible to determine the reaction rate constant, the concept of contact efficiency β was introduced to analyze the experimental data. Then, it can be concluded that the value β approaches to a constant value as the diameter of tower becomes larger.
This result is available for the design of carbonization plant of coal by use of fluidized beds.
