CO2 Removal from Air in a Countercurrent Rotating Packed Bed, Experimental Determination of Height of Transfer Unit

Carbon dioxide capture is a key issue in climate change mitigation. For decades the removal of carbon dioxide has been an essential step in many industrial processing operations such as the synthesis of ammonia, natural gas purification, and oil refining. In this study, a rotating packed bed has been designed for absorption of carbon dioxide from an air stream. The rotating packed bed is a comp...

Long-term spatial and temporal variability of ambient carbon monoxide in Urmia, Iran

One of the pillars of epidemiologic research on the long-term health effects of air pollution is to estimate the chronic exposures over space and time. In this study, we aimed to measure the intra-urban ambient carbon monoxide (CO) concentrations within Urmia city in Iran, and to build a model within the geographic information system (GIS) to estimate the annual and seasonal means anywhere with...

Statistical trend analysis and forecast modeling of air pollutants

The study provides a statistical trend analysis of different air pollutants using Mann-Kendall and Sen’s slope estimator approach on past pollutants statistics from air quality index station of Varanasi, India. Further, using autoregressive integrated moving average model, future values of air pollutant levels are predicted. Carbon monoxide, nitrogen dioxide, sulphur dioxide, particu...

Use of Carbon dioxide versus air blower in on-pump beating-heart coronary artery bypass surgery

Introduction:  The use of carbon dioxide blower has been recognized as the standard of care in patients undergoing beating coronary artery bypass grafting (CABG) due to higher solubility and lower risk of embolization. On the other hand, the compressed air blower has gone out of use since air can be easily trapped and is less soluble which can cause coronary embolism. The prese...
