This paper presents an image-processing-based model for calculating the interfacial-area concentration (IAC) of a low-pressure microbubble (LPMB) scrubber, which facilitates determination operational conditions scrubber via flow-pattern analysis. The LPMB maximizes interfacial area two-phase systems using bubbly flow. Microbubbles have received attention due to their microscopic sizes, high res...

A side effect of high level waste vitrification at 1100 °C is the volatilization radioactive cesium (Cs), recaptured further on in process as a solid aerosol by dust scrubber. Feedback from industry suggests that Cs combines with technetium (Tc) – simulated here rhenium (Re), chosen for its similar behavior to form volatile species. This work characterized and formation. The first experiment in...

Abstract Maritime shipping is a strategic sector with strong international vocation and management. The need to define regulations valid for many different countries without generating disparities of treatment slowed down the formulation environmental regulations, especially atmospheric emissions. In particular, pertaining reduction sulphur compounds allowed two distinct approaches: use low-sul...

Tougher regulations for emissions reductions require refiners to achieve ever higher sulfur recovery efficiency in their Sulfur Recovery Units. A classic solution is to use an amine-based tail gas clean up unit (TGCU) behind a Claus plant. A U.S. refiner, working on a major capacity increase, evaluated and selected an alternate technology. They selected the SUPERCLAUS® Tail Gas Clean Up Process...
