A mixture model simulation is presented by modeling the axial scrubber in a Closed Circuit Rebreather (CCR). The mixture model is a good substitute for the full Eulerian multiphase model because the interphase laws are unknown in this case. Analysis of mesh size, mesh type and inflation are made to independently characterize their accuracy by means of convergence before further comparisons with...

PURPOSE Medical records must often be stripped of patient identifiers, or de-identified, before being shared. De-identification by humans is time-consuming, and existing software is limited in its generality. The open source MITRE Identification Scrubber Toolkit (MIST) provides an environment to support rapid tailoring of automated de-identification to different document types, using automatica...

In this study, we investigated the remove of combustion particles by means of wet electrostatic scrubbers. In particular, the role of droplet charging on particle capture was investigated. To this end, the experiments were performed to estimate the Droplet Charge to Mass Ratio (D-CMR) for two hollow cone spray nozzles. The experiments revealed that the D-CMR increased linearly with the potentia...

A listing of current boiler and smut collector installations is given illustrating the reduction from 59 to 19 boilers without smut collectors. Maximum boiler size has increased from 57 to 147 th-l. lrrigated perforated plate type scrubbers have been the most numerous units installed but some dry multi-cyclone collectors have also been used. Smuts dewatering systems are examined, some problem a...

Environmental degradation and Economic growth are two important proofs in sustainable development which are followed by steel industry. In this case, energy and environmental damages as sustainability patterns of environment have been investigated in three different dust collectors to select the most environmentally suitable dust collector for electric furnace. In this article, the consumption ...

In the current stage over 85% of world energy demand is supplied by fossil fuels. Coal-fired plants discharged roughly 40% of the total CO2 are the main contributors in CO2 emissions (Kim & Kim, 2004; Yang et al., 2008). Environmental issues caused by exhaust green house gases (GHG) and toxics have become global problems. Through the past studies of five decades, increased GHG levels in atmosph...
