Impeller glass-lined

These impellers are available in nearly any material of construction as well as rubber, rubber-lined, glass-lined. 

In glass-lined vessels, the 3 blade Pfaudler Retreat Curve Impeller (RCI) is often used for liquid-liquid dispersions although the myriad of impeller styles currently available with glass... 

The three manufacturers of glass-lined mixing systems use different methods of attachment of the blades of the impeller(s) to the shaft a.s summarized in Table 6-2.

Ackley [79] suggests use of Equation (9.87) for unbaffied retreat-curve (blade) impellers typically used in glass-lined vessels ... 

Into a 1,000 gallon, jacketed, glass lined reactor equipped with baffles and a two speed (67 and 135 rpm) reversed impeller is introduced 200 g of Richonate 60S (a 60% aqueous slurry of sodium salts of alkylbenzenesulfonic acids) and 364 liters of deionized water, followed by... 

For glass-lined vessels and retreat curve blade impellers and glass-lined turbines, five different types of baffles (shown in Figure 6-7) are commonly used Anger, flattened pipe, h style, concave baffle, and fin. These baffles can be conveniently supported in the vessel heads of glass-lined reactors. Of these, the fin baffle has become a more standard choice. 

For glass-lined vessels, one is no longer limited to the Pfaudler crowfoot, also known as the retreat blade or retreat curve impeller (RCl). Most impeller... 

Agitation in the production scale equipment was changed to include dual glass-lined impellers of D/T = 0.45, consisting of a lower four-blade FBT and an upper four-blade 45° PBT. This was an attempt to increase the volume of the dispersion region and to improve circulation. The modified system did improve reaction rates, but not to the degree desired.

The pH of the latter nutrient medium is adjusted to 7.5 with ION sodium hydroxide solution and is placed in a 30 liter glass fermentor equipped with sparger, impeller, baffles and sampling line. The medium is sterilized by heating at 121°C for two hours, is allowed to cool and is then inoculated with 800 ml of the culture mixture obtained as described above.
