Absorption of Carbon Dioxide in a Bubble-Column Scrubber
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...
متن کاملBiofixation of Carbon Dioxide from Kerosene Combustion and Biomass Production by Spirulina
Background and purpose: CO2 is the main cause of greenhouse effect. Previous studies have shown that CO2 in methane and coal flue gas can lead to microalgae growth. The aim of this research was to study the CO2 biofixation by Spirulina and injecting kerosene flue gas. Materials and methods: A photo bioreactor was fabricated in which kerosene flue gas and air were separately injected. The ph...
متن کاملCommercial scale slurry bubble column reactor optimization
An in-depth numerical study has been carried out to investigate a high-pressure commercial scale (2–8 meter diameter) slurry bubble column reactor (SBCR). Typical superficial gas velocities are in the range of 0.5–3 m/s, and overall vapor hold-ups are in the range of 0.45–0.85. The study revealed that steady compartmental reaction models do not match plant data when reaction time constants are ...
متن کامل[Visualization of stenosis in vascular access by bubble method under carbon dioxide (CO2) angiographic procedures].
A percutaneous transvascular angioplasty (PTA) is performed to relieve failed vascular access for hemodialysis. Angiography using non-ionic iodinated contrast media is the imaging modality of choice for performing PTA. However, the use of iodinated contrast media is contraindicated for patients with a history of iodine allergy. Since 1920, carbon dioxide (CO(2)) has been used as a safe contrast...
