ACTIVATED CARBON PELLETS FOR EFFICIENT VOC & HYDROGEN SULFIDE REMOVAL

ACTIVATED CARBON PELLETS: AN EFFECTIVE VOC & HYDROGEN SULFIDE REMOVAL SOLUTION

VOCs and Hydrogen Sulfide are toxins that are critical to remove from gas streams, but solutions can be costly to plants. Finding an effective product is key to controlling costs and maintaining safe emissions standards.

 

What is Hydrogen Sulfide?

Hydrogen sulfide is a colorless, poisonous gas that smells that rotten eggs and is naturally produced, but can also be created or used in industrial processes, such as petroleum production and refinement, wastewater treatment, textile manufacturing, and more. It’s critical to remove hydrogen sulfide from gas streams because exposure causes symptoms ranging in severity from fatigue to death.

What are VOCs?

There are over 10,000 kinds of VOCs, or volatile organic compounds. Different types of VOCs are emitted from different industrial sources, including landfill sites, manufacturing operations, and chemical processing facilities.

What is Activated Carbon

图片
Activated carbon is one of the most common adsorption media   used on filters to control indoor air quality and reduce pollutants. The popularity of activated carbon is due to its inherent ability to adsorb most organic chemicals due to the large surface area created by the increased activation on the carbon/charcoal surface. When it comes to the capture and control of gaseous compounds present in the indoor air space, activated carbon will quickly and effectively trap these contaminants on this activated filter media. In some cases, the charcoal/carbon material will be treated with additional chemicals during the activation of this material, which will be done through the use of a chemical called potassium permanganate. Potassium permanganate is used in activated carbon filter media to help attract reactions between the carbon media and the oxidation of polar or low molecular weight compounds. In addition, many manufacturers use this chemical additive on carbon filters to help extend

Waste Carbon Recovery for Environmental Sustainability

图片
Used granular (GAC) or extruded (EAC) activated carbon can be recycled through thermal activation, which involves treating the used carbon in a high temperature activation oven at 850°C or above. Recovery by thermal regeneration is only one of the steps in the complete service package. The recovery process consists of two main processes: 1) reactivation process and 2) tail gas treatment and energy recovery process.     The reactivation process itself can be subdivided into four steps. 1) Drying of used carbon The used carbon is fed into the furnace and heated from ambient temperature to 105 - 110°C. Water and some low boiling compounds are evaporated and released into the furnace atmosphere. As long as there is water in the pores,  the temperature of the carbon  remains between 105 and 110°C. 2) Desorption of low boiling point organics. As the carbon dries, the temperature increases further to about 450°C. During this temperature increase, various organic compounds are desorbed from th
