Phase Dispersion

Whenever possible, neutralization of alkaline wastewater should involve low-cost acid. It is conventional to make use of carbonic acid produced via the reaction of carbon dioxide (contained in flue gases) with water according to the following equation: Carbon dioxide content in the flue gas stream varies from 10% to 15%. The flue gas stream may either be passed to the wastewater contained in the recarbonizers, or. enter the scrubbers (which are continually sprayed with wastewater) from the bottom in oountercurrent. The reactors, in which recarbonation occurs, have the ability to expand the contact surface between gaseous and liquid phase. This can be achieved by gas phase dispersion in the liquid phase (bubbling), by liquid phase dispersion in the gas phase (spraying), or by bubbling and spraying, and mixing. These concurrent operations are carried out during motion of the disk aerator (which is a patent claim). The authors describe the functioning of the disk aerator, the composition of the wastewater produced during wet gasification of carbide, the chemistry of recarbonation and decarbonation, and the concept of applying the disk aerator so as to make the wastewater fit for reuse (after suitable neutralization) as feeding water in acetylene generators.

Abstract A gas-solid chromatographic method is described for the separation and determination of 5 medicinal gases at ambient temperature, using 2 gas chromatographic columns, Porapak Q and Molecular Sieve 13X, operated in series with a 6-port thermal conductivity detector and I recorder. An electronic digital integrator is used for calculating peak areas. Data on retention time, linearity, reproducibility of injection, and comparison with absorption methods are presented. Analytical results for oxygen, nitrogen, carbon dioxide, ethylene, and nitrous oxide are attainable within 1.0% without the use of an internal standard.
