Download or read book Experimental Analysis of Boiling Enhancement from Surfactant Addition with Electric Fields written by Jordan P. Mizerak and published by . This book was released on 2014 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis consists of an experimental investigation of the effect of surfactants on the boiling curve of water. Via adsorbtion to the boiling surface, surfactants alter the surface energy interaction during bubble formation at nucleation sites. The surfactants initially enhance the heat transfer coefficient at the onset of nucleate boiling due to higher nucleation density and higher bubble departure frequency. The critical heat flux, on the other hand, generally dropped by nearly 50% in the presence of surfactants. As these surfactants are charged molecules, the application of an electric field was used to increase or decrease adsorption of surfactants on the boiling surface, thereby tuning the level of boiling enhancement during the onset of nucleate boiling and further illustrating the role of surfactants in the boiling process.
Download or read book Nonionic Surfactant Properties and Plant Species Affect Surfactant Enhancement of Primisulfuron Phytotoxicity written by M. Czajka and published by . This book was released on 1995 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research was conducted to determine the relationship between surfactant properties and plant species (common lambsquarters, green foxtail, kochia, redroot pigweed, and sunflower) on primisulfuron phytotoxicity. Primisulfuron phytotoxicity was enhanced by all surfactants. Only surfactant HLB consistently related to enhancement of Beacon phytotoxicity. Optimum HLB values varied from 11.5 to 17.9 depending on plant species and surfactant chemistry. Surfactants having similar HLB values but different chemistry differed in their enhancement of Beacon phytotoxicity to various species. Surfactant enhancement of Beacon varied with plant species, even when surfactants had similar HLB values. The data indicate that plant species, surfactant chemistry, and surfactant HLB influence surfactant enhancement of Beacon phytotoxicity.

Available in PDF, EPUB and Kindle. Book excerpt: A response to increasingly stringent regulation of pollution and toxicity levels in industrial waste discharge, Micellar Enhanced Ultrafiltration: Fundamentals & Applications offers the most complete book available on the benefits and use of micellar-enhanced ultrafiltration (MEUF) to achieve continuous removal of organic and inorganic pollutants. An Unparalleled Book That Addresses Both Academic and Industrial Points of View Several membrane-based techniques, such as microfiltration, ultrafiltration, nanofiltration, and reverse osmosis, are currently used in a wide range of applications throughout the textile, pulp and paper, sugar, chemical, pharmaceutical, biomedical, biotechnological, and food industries. However, although reverse osmosis is an effective means of removing contaminants, this book explains why MEUF is a better substitute, as it less expensive, less energy-intensive, and more efficient and practical for a wider range of applications. Topics covered include: Effects of pollution in water and its consequences Various treatment processes and membrane technologies Fundamentals of ultrafiltration Outline of various membrane modules and modeling approaches Principles of colloid chemistry Theories of micelle formation Stability and dynamics of micelles Phenomena of counterion binding Solubilization of organic pollutants Selection criteria for surfactants Various flux enhancement techniques Recovery of precious metals This book conveys how, with proper selection of surfactant and membrane, MEUF can be used to efficiently remove almost all metal ions (heavy metals, lanthanides, radioactive materials, etc.) with reasonably high efficiency and throughput. It also details the MEUF process for removal of inorganic (cations, anions, and their mixture) and organic pollutants. The authors explain how the economy of the overall process makes recovery and reuse of surfactants essential, and they address various influencing factors on the increase in throughput and the resulting operating problems. Elaborating on technologies involving precipitation and other methods, they also illustrate additional potential applications for MEUF technology.

Download or read book Multi scale Systematic Surfactant Structure performance Studies in Tight Carbonate Reservoirs and at High Temperature and Salinity Conditions written by Opeoluwa W. Olawale and published by . This book was released on 2019 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: In tight carbonate reservoirs, the full potential for enhanced oil recovery (EOR) offered by surfactant flooding remains underutilized. The main challenge is that it is not yet possible to determine a priori the optimal surfactant to deploy, and empirical testing of different surfactant formulations is prohibitively costly. The objective of the presented research is to tackle this challenge by developing a predictive correlation between the surfactant molecular properties and their effectiveness as the EOR agents. To attain this objective, we tested the hypothesis that oil recovery enhancement by surfactants in fractured tight carbonate reservoirs is dependent on the adsorption mechanism of the surfactant to the carbonate surface. The adsorption, in turn, depends on the surfactant molecular structure and the electrochemical interactions within the rock/brine/oil system. The results confirm that cationic surfactants with different tail lengths exhibit different levels of adsorption, despite the same head group, underscoring the importance of hydrophobic interactions. We found that in tight carbonate reservoirs, adsorption is inversely correlated with the recovery enhancement by surfactants. However, cationic surfactants yield very low oil recovery in tight oil-wet carbonate reservoirs or at high salinity despite having low adsorption compared to the other surfactant types. By contrast, nonionic surfactants with low adsorption and high emulsifying tendencies appear to be most effective for enhancing matrix access in these systems. Finally, the equilibrium adsorption levels of polyoxyethylenated nonionic surfactants were shown to be inversely correlated with the newly defined structural parameter – the ratio of the ethylene oxide count to approximate tail carbon number (EO:TCN).
