Explosion behavior of ammonia and ammonia/methane in oxygen‐enriched air

20.07.2017 | Valeria Di Sarli, Francesco Cammarota, Ernesto Salzano, Almerinda Di Benedetto, Process Safety Progress, 2017

The effect of enriching air with oxygen on the explosion behavior of ammonia and ammonia/methane has been experimentally investigated in a closed 5‐l cylindrical vessel. Results have shown that for both ammonia and ammonia/methane, when moving from air to pure oxygen, a transition takes place ...


Dropwise Condensation on Advanced Functional Surfaces – Theory and Experimental Set‐Up

19.07.2017 | Jakob Sablowski, Simon Unz, Michael Beckmann, Chemical Engineering & Technology, 2017

Abstract Compared to filmwise condensation on conventional condenser surfaces, heat transfer can be significantly enhanced by tuning the wettability of the surface to promote dropwise condensation. Following rapid advances in surface engineering, the last years have seen an unprecedented ...


Enriched‐air or pure oxygen as oxidant for gas‐to‐liquid process with microchannel reactors

19.07.2017 | Mohammad Ostadi, Magne Hillestad, Chemical Engineering & Technology, 2017

Abstract The syngas production step is one of the most costly steps in a gas to liquid plant. It is common practice to use oxygen as oxidant in the reforming step. However, by the introduction of microchannel reactors with their remarkable heat transfer characteristics, high active catalyst ...


Development of a hydrothermal liquefaction process using microalgae for improvement of bio‐crude yield and phosphorous content

19.07.2017 | Cheol-Min Yang, Choul-Gyun Lee, Jong-In Won, Chemical Engineering & Technology, 2017

Abstract Hydrothermal liquefaction (HTL) is a thermal depolymerization process used to convert wet biomass such as microalgae into bio‐crude oil. Four main products, gas, bio‐crude oil, an aqueous phase, and solid residue, are generated through HTL. In this study, we investigated HTL ...


Analysis of in situ microscopy images of flocculated sediment volumes

19.07.2017 | Michael R. MacIver, Marek Pawlik, Chemical Engineering & Technology, 2017

Abstract An in situ microscopy method was applied to study the sediment volumes that result from batch settling of polymer flocculated kaolin suspensions. Statistical methods were applied including chord length distributions, perimeter based fractal dimension of the void areas, white area ...


Experimental investigation on gas‐solid behavior in the fluidized‐bed with superfine particles

19.07.2017 | Takashi Goshima, Yumi Yoshida, Kouya Shimazaki, Kenta Fukudome, Kei Mizuta, Susumu Nii, Chemical Engineering & Technology, 2017

Abstract Fluidized beds have been commercially utilized in gas‐solid contacting processes such as FCC process. Attempts have been made for bubbling fluidized beds to enhance gas exchange between the bubble phase and the emulsion phase as well as to increase bubble hold up. In this study, ...


Application of artificial neural network‐based generic model control to multivariable processes

19.07.2017 | Reddi Kamesh, K. Yamuna Rani, Asia-Pacific Journal of Chemical Engineering, 2017

Abstract The present study focuses on the application of a purely data‐driven artificial neural network (ANN)‐based generic model controller (GMC) for multiple‐input and multiple‐output systems with relative degree one or more. The approach is based on development of an ANN model relating the ...


Mixing Strategy Effect on Dispersion of Amine during Reagent Production for Flotation Applications

18.07.2017 | Mohammad Hussein, Adam Donaldson, The Canadian Journal of Chemical Engineering, 2017

ABSTRACT Mixing and dispersion strategies for the inline production of amine flotation reagents is explored for 2.54 cm and 5.08 cm process lines and flow rates comparable to current commercial production systems. Through video analysis of injection into a clear pipe, the dispersion ...


Lessons in process safety management learned from a pesticide plant explosion in Taiwan

17.07.2017 | Horng‐Jang Liaw, Process Safety Progress, 2017

A massive explosion in Taichung, Taiwan, in 2016, which was attributed to the thermal decomposition of o,o‐dimethyl phosphoramidothioate, resulted in one fatality and one injury. This accidental explosion stemmed from certain elements being absent from process safety management (PSM), including ...
