Capturing CO2 from Biogas by MEA (Monoethanolamine) using Packed Bed Scrubber

Capturing and Conversion of Co2 to Methanol in a Chemical Looping Packed Bed System

Some new efforts based on chemical-looping system for capturing and converting CO2 into methanol are discussed in this study. In chemical-looping technology, an oxygen carrier has to be transported between circulating fluidized beds, which require additional energy and processes, like cyclone and seals. This may be one of the main drawbacks at high operating temperatures. In a new reactor conce...

Acid Packed Bed Scrubber Using Two Methods: a Case Study in a Pig Facility

The use of air cleaning systems to reduce ammonia emissions from animal houses is increasing. These systems are normally used in order to comply with local or national regulations of ammonia emission. Therefore, accurate determination of the proportion of ammonia being removed by these systems is crucial. There are two main methods available to measure ammonia removal efficiency of scrubbers: a...

Catalytic Combustion of Biogas-Hydrogen Mixtures in a Packed Bed Reactor

Hydrogen sulfide removal from biogas using chemical absorption technique in packed column reactors

The toxicity and corrosion potential of hydrogen sulfide in raw biogas underlines the need for biogas purification. Several techniques available for removal of hydrogen sulfide from biogas are out of the reach for common end users due to lack of knowledge, higher running costs, and insufficient operational skills. The present experimental study aims to propagate hydrogen sulfide removal techniq...

Experimental Studies of CO2 Capturing from the Flue Gases

CO2 emissions from combustion flue gases have turned into a major factor in global warming. Post-combustion carbon capture (PCC) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas CO2. To test a new solvent (AIT600) for this purpose, a small pilot plant was used. This paper presents the results of studies ...
