Diatomite releases silica during spirit filtration.
The purpose of this study was to ascertain whether diatomite is an inert filter aid during spirit filtration. Surely, any compound with a negative effect on the spirit composition or the consumer's health could be dissolved. In this study different diatomites were treated with 36% vol. ethanol/water mixtures and the amounts and structures of the extracted compounds were determined. Furthermore,...
متن کاملTwo Phase Streaming Potentials
The streaming potentials generated by the flow of both liquid and gas through either a Pyrex capillary tube or else an unconsolidated Pyrex porous medium were investigated. This mixture of distilled water plus nitrogen gas simulated wet steam but allowed experiments to be run at room temperature. Single-phase flow of distilled water alone resulted in a constant voltage-to-pressure drop ratio, W...
متن کاملFrequency-Dependent Streaming Potentials.
An experimental apparatus and data acquisition system was constructed to measure the streaming potential coupling coefficients as a function of frequency. The purpose of the experiments was to measure, for the first time, the real and imaginary portion of streaming potentials. In addition, the measured frequency range was extended beyond any previous measurements. Frequency-dependent streaming ...
متن کاملInteraction of ions and water in gramicidin A channels: streaming potentials across lipid bilayer membranes
For very narrow channels in which ions and water cannot overtake one another (single-file transport), electrokinetic measurements provide information about the number of water molecules within a channel. Gramicidin A is believed to form such narrow channels in lipid bilayer membranes. In 0.01 and 0.1 M solutions of CsCl, KCL, and NaCl, streaming potentials of 3.0 mV per osmolal osmotic pressure...
متن کاملLaboratory Study of Frequency Dependent Streaming Potentials
Frequency dependent streaming potentials were measured on a glass capillary, porous filter, and a sample of Boise sandstone. The pore diameters for these three samples range from 1 millimeter to 34 micrometers. The frequencies used in these experiments range from 0-600 Hz with the critical frequencies being 6.8 Hz, 90 Hz, and 400 Hz for the three specimens. The fluid was moved relative to the s...
