Flow enhancers

Nonnutrient Additives. Nonnutritional dietary additives provide antioxidants to preserve freshness, flavor enhancers to stimulate food selection, color to meet the owner s expectations, pellet biaders to minimi2e fine particles, mycostats to minimi2e mold growth, and iagredient-flow enhancers. Pet foods do not iaclude coccidiostats, antibiotics, added hormonal materials, and fly-larval iasecticides used ia other animal feeds. [Pg.151]

Fumed silicas (Si02). Fumed silicas are common fillers in polychloroprene [40], natural rubber and styrene-butadiene rubber base adhesives. Fumed silicas are widely used as filler in several polymeric systems to which it confers thixotropy, sag resistance, particle suspension, reinforcement, gloss reduction and flow enhancement. Fumed silica is obtained by gas reaction between metallic silicon and dry HCl to rend silica tetrachloride (SiCU). SiC is mixed with hydrogen and air in a burner (1800°C) where fumed silica is formed ... [Pg.633]

Equation 10.30 is known as Stefan s Law(3). Thus the bulk flow enhances the mass transfer rate by a factor Cj/Cjj, known as the drift factor. The fluxes of the components are given in Table 10.1. [Pg.578]

W. Ritter, C. Meyer, W. Zollner, C. P. Herold, and S. von Tapavicza. Use of selected acrylic and/or methacrylic acid ester copolymers as flow enhancers in paraffin-rich crude oil and crude oil fraction (II) (Verwendung ausgewahlter Copolymeren der Acryl- und/oder Methacrylsaureester als FlieBverbesserer in paraffinreichen Erdolen und Erdolfraktionen [II]). Patent EP 332002,1989. [Pg.452]

Flow-Enhanced Desorption of Adsorbed Flexible Polymer Chains... [Pg.67]

Adsorption and Desorption. The adsorption of PS was carried out by introducing the polymer solutions into the cell via a hypodermic syringe. The solution concentrations used for adsorption were 700 PPM for PS-20, 1000 PPM for PS-8, and 1200 PPM for PS-4. According to the previous work by Takahashi et al. (12), those concentrations are large enough to obtain saturated surface coverages. The solution was kept in the cell over a period of one day to insure equilibrium. At the end of one day the supernatant solution was displaced by the pure solvent. For studies of flow-enhanced desorption the pump was... [Pg.70]

Examination of Figures 2 to 4 clearly indicates flow enhancement of the desorption as seen by the substantial decreases in adsorbance once flow is applied. The overall trend of the desorption curves for the three molecular weight samples is similar and is characterized by a fairly rapid initial desorption followed by an approach to steady state. The desorption rate increases with the velocity gradient whereas the steady state adsorbance decreases as the flow is increased. [Pg.72]

A method frequently used to improve performance of trenches is to incorporate flow enhancement. Typically, this involves the use of a pump to lower the fluid level in the trench, and thus increase the hydraulic gradient. An additional benefit is that the continued flow toward the pump also tends to collect the LNAPL in a smaller area, where it is easier to recover. Water recovered from the trench may be treated for off-site disposal or reinjected upgradient to enhance the flow further. Increased... [Pg.215]
