“…During the past 15 years several studies (1,9,11) have been made at the University of Oklahoma involving tray design as related to absorbers and fractionators. In (l) To left: unsteady flow of heat from condensing stream to a cylinder filled with sand, visual condensation of steam on a copper tube.…”

“…On this basis the standard (Francis) weir equation should be applicable at low heads, with this particular column up to about 5 gallons per minute liquid throughput. For a circular weir of 2.0-inch diameter, the discharge formula is, Q = 18.9 ffz3'2 (1) where Q = liquid, gal./min. Hl = head, in inches of liquid over weir (Hz, < D/4) For intermediate fluid heads, the equation for a free-running orifice of 2-inch diameter and with a discharge coefficient of 0.5 should apply:…”

“…Little data are available, however, in the literature on the interaction of liquid and vapor in the column on the nature of the fluids (froths and foams) which are formed above the trays, and the pressure differentials existing between adjacent bubble plates. In order to gain a better insight into the quali- 1 Present address, Humble Oil and Refining Company, Bayton, Texas. * Present address, Phillips Petroleum Company, Borger, Texas. tative and quantitative behavior of such phenomena, the present investigation has been carried out experimentally in a 12-inch i. d. column equipped with a 12 X 24-inch visible glass section.…”

“…To determine the optimum size of column, it is necessary to know both the variation of entrainment with velocity and plate spacing and the effect of a given amount of entrainment on the efficiency. Considerable experimental data have recently been obtained as to the amount of entrainment incurred under various conditions (1,2,3,5,7).…”

of dissolved oxygen is entirely removed when a liquid is cooled as much as 10°F. by vacuum evaporation. The same is true of carbon dioxide and many other gases. Some previous data on removal of carbon dioxide by vacuum evaporation at somewhat higher temperatures were published by Jackson and McDermet (2).Preliminary testing on hard water and on carbonated soft water indicates that carbonate removal by vacuum evaporation at low temperatures is practically as efficient as at high temperatures when the evaporation produces a temperature drop of 10°F. or more. There are numerous cases in chemical process work where chilling of various liquids is being accomplished by mechanical refrigeration and where the automatic degasifying action of vacuum refrigeration would more than justify a change to the latter process. There are other conditions where refrigeration is being applied to liquids that must retain certain dissolved gases. In cases of this kind, vacuum cooling can be applied indirectly through tubes or any convenient heat transfer medium.Preliminary experimental work indicates that vacuum cooling of milk improves its flavor by removing traces of dissolved gases. A pilot plant was installed at Cornell University; experimental work is well under way, and considerable data have been collected. Some of these data will doubtless be published in the near future.
