Enhancement of Heat Transfer by Ultrasound: Review and Recent Advances
International Journal of Chemical Engineering - Tập 2011 Số 1 - 2011
M. Legay, Nicolas Gondrexon, Stéphane Le Person, P. Boldo, André Bontemps
This paper summarizes some applications of ultrasonic vibrations regarding heat transfer enhancement techniques. Research literature is reviewed, with special attention to examples for which ultrasonic technology was used alongside a conventional heat transfer process in order to enhance it. In several industrial applications, the use of ultrasound is often a way to increase productivity in the pr... hiện toàn bộ
An Experimental Approach to Formulate Lignin-Based Surfactant for Enhanced Oil Recovery
International Journal of Chemical Engineering - Tập 2019 - Trang 1-6 - 2019
Kenny Ganie, Muhammad A. Manan, Mohamad Arif Ibrahim, Ahmad Kamal Idris
The higher cost of chemical surfactants has been one of the main reasons for their limited used in enhanced oil recovery (EOR) process. Hence, the reason for developing lignin-based surfactant is to lower the cost of chemicals as it does not tie to the price of crude oil as compared to petroleum-based surfactants. Besides, lignin is biodegradable and easily extracted from plant waste. The objectiv... hiện toàn bộ
Toxicity Assessment of Sediments with Natural Anomalous Concentrations in Heavy Metals by the Use of Bioassay
International Journal of Chemical Engineering - Tập 2010 - Trang 1-6 - 2010
F. Martı́n, Marlon Escoto, Juan Fernández, Emilia Fernández Ondoño, Elena Arco-Lázaro, Manuel Sierra Aragón, Carlos Dorronsoro
The potential toxicity in riverbed sediments was assessed with a bioassay using the bioluminescent bacteriaVibrio fischeri. The selected area was characterized by the presence of ultramafic rocks (peridotites), and the sediments had high values in Ni, Cr, and Co. For the toxicity bioassay withVibrio fischeri, water-soluble forms were used. The results indicated that most of the samples had a very ... hiện toàn bộ
A Review on Heavy Metals (As, Pb, and Hg) Uptake by Plants through Phytoremediation
International Journal of Chemical Engineering - Tập 2011 Số 1 - 2011
Bieby Voijant Tangahu, Siti Rozaimah Sheikh Abdullah, Hassan Basri, Muhamad Idris, Nurina Anuar, Muhammad Mukhlisin
Heavy metals are among the most important sorts of contaminant in the environment. Several methods already used to clean up the environment from these kinds of contaminants, but most of them are costly and difficult to get optimum results. Currently, phytoremediation is an effective and affordable technological solution used to extract or remove inactive metals and metal pollutants from contaminat... hiện toàn bộ
