Gas pocket

In hquid service the lines must constantly slope downward toward the transmitter from the taps to prevent possible gas pockets. In gas service the lines should drain to prevent condensate accumulation or, if the condensate is used to transmit the pressure from the taps to transmitter, the condensate legs must be of equal height. 

Cake-discharge methods are the chief distinguishing feature among the various designs. That of the Industrial Filter Pump Hydro-Shoe, for example, removes cake from the tubes by filtrate backflushing assisted by the shocking action of a compressed-gas pocket formed...

Presence of crevices, dead-ends, etc. Effective protection by inhibitors relies on the continued access of inhibitor to all parts of the metal surface Aeration and Movement of the Liquid). It frequently happens that this condition is difficult to achieve due to the presence of crevices at joints, deadends in pipes, gas pockets, deposits of corrosion products, etc. Corrosion will then occur at these sites even though the rest of the system remains adequately protected.

Simethicone (Mylicon) and charcoal are used as anti-flatulents (against flatus or gas in the intestinal tract). Simethicone has a defoaming action that disperses and prevents the formation of mucus-surrounded gas pockets in tiie intestine Charcoal is an absorbent that reduces the amount of intestinal gas. 

Gas pockets in the intestinal coating and blood in the intestines were observed in five male mice treated with trichloroethylene in drinking water at a dose 660 mg/kg/day (Tucker et al. 1982). Similar effects were observed in five male mice at a dose of 217 mg/kg/day, with no mice affected at a doses of 393 or 18 mg/kg/day. Unfortunately, the number of mice examined for this effect was not clearly stated. Although this effect was not dose-related, it is an interesting observation and appears to be consistent with the human cases of gas-filled cysts in the submucosa of the small intestine observed in persons occupationally exposed to trichloroethylene (Nakajima et al. 1990a) (see Section 2.2.1.2). 

The main problem, the height-dependent differential pressure between the catho-lyte gap and oxygen across the ODC, could be solved with the pressure compensation system based on oxygen supply via gas pockets [1] (see Fig. 4.2). The first successful piloting was done in October 1995 on the basis of Bayer engineering and construction. In a four-gas-pocket element with each electrode segment of 180 x 180 mm2 individually supplied with power, the proper function of pressure compensation could be proven for a total height of 90 cm. 

Mechanism of Action Anantiflatulent that changes surface tension of gas bubbles, allowing easier elimination of gas. Therapeutic Effect Drug dispersal, prevents formation of gas pockets in the G1 tract. 

FIGURE 1.7 Three typical cellulose fibers adsorbed on the wall of a glass poured with champagne the gas pockets trapped inside the fibers lumen and responsible for bubble formation clearly appear (bar = 100 pm) (Photographs by Gerard Liger-Belair). 

A scheme is displayed in Fig. 1.11, where the geometrical parameters of the tiny gas pocket growing by diffusion are defined. 

Taking info account the diffusion of C02-dissolved molecules from the liquid bulk to the gas pocket, the growth of this gas pocket with time t was linked with both liquid and fiber paramefers as follows (Liger-Belair et ah, 2005b) ...
