Steam Hydration of Calcium Oxide for Solid Sorbent Based CO2 Capture: Effects of Sintering and Fluidized Bed Reactor Behavior

12-Dec-2014 | Alan Wang; Niranjani Deshpande; L.-S. Fan, Energy & Fuels, 2014

This study reports on the hydration characteristics in the three-step carbonation–calcination reaction (CCR) process with intermediate steam hydration. Specifically, experimental results of sorbent reactivation in a fluidized bed steam hydration reactor are presented along with the effect of the ...

Metal recovery from end‐of‐life hydrotreating catalysts by selective precipitation: Laboratory tests and preliminary process analysis

11-Nov-2014 | Alessio Cibati, Francesca Pagnanelli, Luigi Toro, Environmental Progress, 2014

Hydrotreating catalysts (HTCs) are a waste byproduct of the petroleum refining industry. The recovery of intrinsic and sorbed metals from spent catalysts is desirable for meeting environmental disposal regulations, as well as for the metal resell value. In this study, innovative process schemes ...

Perspectives in process analysis

11-Sep-2013 | Rudolf W. Kessler, Journal of Chemometrics, 2013

Process analysis is a transdisciplinary technology. Process chemists, process engineers, chemometricians, and many other technologists must work together and put more emphasis on the essentials of science of each discipline. This perspective analyzes potential strategies for intelligent ...

Water Footprint Assessment for Wastewater Treatment: Method, Indicator, and Application

05-Jul-2013 | Ling Shao; G. Q. Chen, Environmental Science & Technology, 2013

The water footprint in terms of the sum of both direct and indirect water cost of wastewater treatment is for the first time accounted in this work. On the basis of the hybrid method as a combination of process analysis and input–output analysis, a detailed water footprint accounting procedure is ...

Kinetic Evaluation of Removal of Odorous Contaminants in a Three-Stage Biological Air Filter

25-Jul-2012 | Dezhao Liu; Michael Jørgen Hansen; Lise Bonne Guldberg; Anders Feilberg, Environmental Science & Technology, 2012

Biofiltration is a cost-effective technology for removing air contaminants from animal facilities. Kinetic analysis can be helpful in understanding and designing the process but has not been performed on full-scale filters treating complex mixtures. In this study, kinetics was investigated in a ...

Algal Biomass Constituent Analysis: Method Uncertainties and Investigation of the Underlying Measuring Chemistries

08-Feb-2012 | Lieve M. L. Laurens; Thomas A. Dempster; Howland D. T. Jones; Edward J. Wolfrum; Stefanie Van Wychen; Jordan S. P. M ..., Analytical Chemistry, 2012

Algal biomass compositional analysis data form the basis of a large number of techno-economic process analysis models that are used to investigate and compare different processes in algal biofuels production. However, the analytical methods used to generate these data are far from standardized. ...
