Studies on the Adsorption Removal of Hydrogen Sulfide Gas

Adsorption of Hydrogen Sulfide at low temperature

From an ecological perspective is biogas an important source of energy. It is produced from fermentation of organic material, e.g. household waste and wastewater sludge. The composition of the gas depends on the raw material and varies between 65-85% methane, 15-35% carbon dioxide and small amounts of ammonia and hydrogen sulfide. To use the biogas it is important to purify it from hydrogen sul...

The Performance of Compost Biofilter for Hydrogen Sulfide Removal from Contaminated Air

In order to evaluate the performance of biofilter for H2S removal from contaminated air, a 120×14 cm column biofilter was constructed using clear polyacrylic material in conjunction with H2S production and control systems. The column was divided into four stages using perforated plates. The column was packed with a mixture of mushroom compost and snail shell (4:1).&#10 The performance of biofil...

Hydrogen Sulfide Gas Levels Post Feeding

Hydrogen sulfide gas emissions during disturbance and removal of stored spent mushroom compost.

Spent mushroom compost (SMC) is a by-product of the mushroom industry that is used as an agricultural fertilizer. In Europe, SMC storage and use are governed by EU Nitrates Directive 91/676/EEC to protect waterways against pollution by nitrates. A health and safety risk was identified during the removal of stored SMC for land application, as the stored SMC released high levels of toxic H2S gas ...
