Caustic Scrubber Designs for H2S Removal from Refinery Gas Streams

Caustic scrubbing is a technology that has been used for the removal of H2S and other acid species from gases in different industries for many years. Improvements in design and control strategies, favorable prices for caustic compared with other non-regenerable H2S scavenging chemicals, and the potential for sales value for the NaHS (sodium bisulfide) product have made caustic scrubbing an econ...

Removal of H2S from Synthetic Waste Gas Streams Using a Biotrickling Filter

The removal of hydrogen sulfide (H2S) from airstreams was studied in a biotrickling filter packed with porous lava as a carrier of Thiobacillus thioparus (DSM5368) with counter current flows of the air and liquid streams. The effect of operating parameters on biotrickling filter performance was studied. Experiments were performed at different empty bed residence times (9-60 sec), and...

How to Enhance Gas Removal from Porous Electrodes?

This article presents a structure-based modeling approach to optimize gas evolution at an electrolyte-flooded porous electrode. By providing hydrophobic islands as preferential nucleation sites on the surface of the electrode, it is possible to nucleate and grow bubbles outside of the pore space, facilitating their release into the electrolyte. Bubbles that grow at preferential nucleation sites...

Batch Equilibrium and Kinetics Studies of Cd (II) Ion Removal from Aqueous Solution Using Porous Chitosan Hydrogel Beads

In this study chitosan hydrogel beads with porosity ~ 0.86 and diameter ~ 20.07 mm were prepared from 85 % deacetylated chitosan for removal of Cd2+ ions from aqueous solutions.  Chitosan powder was dissolved into dilute acetic acid as solvent and formed into spherical beads using a phase inversion technique. The effect of temperature, initial ...
