Design Options for Avoiding Hydrates in Deep Offshore Production

10.10.2014 | Carlos A. B. R. Cardoso; Marcelo A. L. Gonçalves; Ricardo M. T. Camargo, Journal of Chemical & Engineering Data, 2014

Hydrate blockage in subsea systems is responsible for a portion of lost profits in several deepwater oil fields. This problem tends to worsen in the fields recently discovered in Brazilian Pre-Salt layer due to greater water depth, higher pressure, lower temperature, and oil more prone to ...

The Combined Effect of Thermodynamic Promoters Tetrahydrofuran and Cyclopentane on the Kinetics of Flue Gas Hydrate Formation

08.10.2014 | Nagu Daraboina; Nicolas von Solms, Journal of Chemical & Engineering Data, 2014

Carbon dioxide (CO2) capture through hydrate crystallization is a promising method among the new approaches for mitigating carbon emissions into the atmosphere. In this work, we investigate a combination of tetrahydrofuran (THF) and cyclopentane (CP) on the kinetics of flue gas (CO2:20 mol %/N2) ...

Density, Surface Tension, and Cloud Point of Aqueous Solutions of β-Cyclodextrin-polyethylene Glycol

02.10.2014 | Yuan Liu; Changjun Zou; Taiyang Wang; Ming Li, Journal of Chemical & Engineering Data, 2014

The physical property data (density, surface tension, and cloud point) for aqueous solutions of β-cyclodextrin-polyethylene glycol have been determined at temperatures from (293.15 to 313.15) K and atmospheric pressure. Results show that the density and surface tension decrease as the temperature ...

Design of a Gamma Densitometer for Hydrocarbon Fuel at High Temperature and Supercritical Pressure

01.10.2014 | Zhuqiang Yang; Qincheng Bi; Yong Guo; Zhaohui Liu; Jianguo Yan; Qiang Zhang, Journal of Chemical & Engineering Data, 2014

The densities of endothermic hydrocarbon fuel at supercritical pressure condition are measured online using a radial measurement method. The densitometer is based on the attenuation theory of gamma ray using a count rate mode. One advantage of the method is that it is noninstrusive and practical ...

New “Magmolecular” Process for the Separation of Antimony(III) from Aqueous Solution

29.09.2014 | Ali Asghar Rooygar; Mohammad Hassan Mallah; Hossein Abolghasemi; Jaber Safdari, Journal of Chemical & Engineering Data, 2014

In this work, the separation potential of a new “magmolecular” process for ions of antimony(III) from wastewater was studied. The magmolecular process is a technique in which a high gradient magnetic field is applied to eliminate heavy metal from wastewater. In this process, specifically we have ...
