Vapor‐liquid equilibrium determination by a new apparatus

Abstract

Since bubble growth rate varies from bubble to bubble, it is not possible by the present method to determine how bubble growth rate varies with the surface temperature. This will require obtaining several bubble photographs during any one temperature drop. CONCLUSIONSThe following conclusions have resulted from this study.

Computer‐aided Measurement of Vapour‐Liquid Equilibria in a Dynamic Still at Sub‐Atmospheric Pressures

Phase equilibria on four binary systems containing 3-methylthiophene

“…The VLE runs were conducted with a circulation still of the Yerazunis-type [5] built at the glass workshop of Helsinki University of Technology with minor modifications to the original design [6]. Experimental setup is described in detail in the previous works [6,7].…”

Phase equilibrium measurements for systems containing propanenitrile with tert-butyl ethyl ether and C4-hydrocarbons

“…Two isobaric VLE measurements for the binary system of ETBE and propanenitrile were carried out with a circulation still apparatus of the Yerazunis-type [8]. The equipment was built in the glass workshop of Helsinki University of Technology with minor modifications composed to the original design [9].…”
