The scrubbing solution consists of dilute sodium hydroxide to which enough hydrogen peroxide is added to react with the hydrogen sulfide according to the equation: 4H2O2 + H2S → H2SO4 + 4H2O. The equation shows, that 4 parts of hydrogen peroxide by weight are needed for each part of H2S present in the gas to be cleaned.
2012329 · The present work discusses the startup and operation of different biotrickling filters during the simultaneous removal of NH3, H2S, and ethyl mercaptan (EM) for odor control, focusing on (a) the impact of pH control in the stability of the nitrification processes during reactor startup and (b) the crossed effects among selected pollutants and their byproducts. Two biotrickling filters were ...

2011112 · In winemaking, nutrient supplementation is a common practice for optimising fermentation and producing quality wine. Nutritionally suboptimal grape juices are often enriched with nutrients in order to manipulate the production of yeast aroma compounds. Nutrients are also added to active dry yeast (ADY) rehydration media to enhance subsequent fermentation performance.
ZnO catalyst method proved to be the most effective for sulfur compounds removal and H2S in particular. From the standpoint of high H2S removal efficiency, zinc oxide is more attractive than iron oxide because of more favorable sulfidation thermodynamics which can get very low outlet concentration.
