Gas & Air

One of the most important things in today's world is to breathe clean air!
CarbUSA offers CEVC-Series and tailor-made products for OEM manufacturers who provide products and services for such indoor air treatment applications and provide solutions efficiently and affordably treat contaminants at air emission sources, allowing them to meet stringent emission control regulations.

Wastewater and Sewage Treatment Plants

Odor nuisance in wastewater treatment plants has become a major environmental issue with the increase in population density, public demand, and increase in the number of contaminants in wastewater. The gases which cause Odor are H2S, Mercaptans, TVOC (Toluene, Benzene, Xylene), SO2, Ammonia (NH3), etc. Mainly, Hydrogen Sulfide (H2S) – which contributes to the rotten egg smell and causes a wide range of health effects – can even lead up to death when someone is exposed to high concentrations. Further, these gases are very corrosive and corrode pumps, fans, pipes, and other equipment. carbUSA offers a special series of products for removing such gases, eliminating health hazards as well as better use of the plant and equipment. As the products are with normal grades, impregnated grades, and advanced catalytic grades, customers can have a wide variety of choices for products. Especially, the catalytic activated products with an H2S breakthrough capacity of 0.3g/cc give extremely efficient and economical performance increasing the life span of the adsorbers, thus the downtime in the wastewater treatment plants.

Ground Air / Landfill Gas Treatment

Gaseous emissions are not restricted to atmospheric disposal; contaminated air can seep into the ground, polluting the soil bed and posing further concerns in terms of environmental deterioration and building integrity. Treatment of these gases is very important because of the toxicity and ignitability of volatile organic compounds (VOC) such as siloxanes present in these gases. In such cases, the air is suctioned out of the soil and then run through an activated carbon filtration that uses either conventional adsorption or solvent recovery, depending on the type of contaminants. carbUSA helps in providing its knowledge and a range of solutions to help with the treatment of such pollutants.

Treatment of Natural Gases – Hydrogen Sulfide, Mercaptan, and Mercury Removal

The production of natural gas also results in the formation of byproducts such as Hydrogen Sulfide and mercury, both of which are extremely dangerous to humans and the environment. These byproducts are also known to damage the catalysts used in production and corrode machinery downstream unless they are maintained at controlled levels, thus affecting output yields and reducing process efficiency.

With tailor-made activated carbon products, CarbUSA keeps your activities well within safety limitations. These include alkali-salt-impregnated activated carbon products and well-advanced catalytic products with 0.3g/cc H2S breakthrough capacity, for H2S and mercaptan removal and Sulphur impregnated products for mercury removal, in a fixed bed adsorption method that can eliminate such dangerous contaminants to allow continued operational efficiency.

Treating Flue Gas/Incinerator Fumes – Mercury and Dioxins Removal

Flue gas from waste incineration plants includes trace levels of a variety of pollutants, including heavy metals and other poisons such as mercury and dioxins. Despite their low concentration, they can cause considerable harm to health and the environment if not fully handled, which is why rigorous emissions rules exist to guarantee they are removed before any waste gas is disseminated.
This demands the use of carefully treated powdered activated carbon, which increases the surface area of contact to achieve up to 99 % removal effectiveness. CarbUSA’s purification materials may meet this need by providing tailored solutions to eliminate contaminants at tiny levels, whether by the direct dosage or granular fixed-bed filtering processes.

Hydrogen Sulfide Removal – Pulp and Paper Plants

Pulp and paper mills commonly deal with hydrogen Sulfide emissions from the production process. Not only is this acidic byproduct extremely toxic and harmful to humans, but it is also highly corrosive and can ruin equipment at the processing plant unless concentration levels are kept within a manageable threshold. Due to this, an efficient purification system is a must in order to avoid constant and expensive replacement of process and control equipment.
The solution CarbUSA can provide here is through activated carbon, ideally treated with alkali salts to neutralize the acidic content, to manage internal acid concentration even at high temperatures, allowing production to continue safely and efficiently.

Treatment of Acid Gases – Hydrogen Sulfide, Sulphur Dioxide, etc.

Sulfur is commonly seen as a contaminant in industrial gaseous emissions, usually in the form of hydrogen sulfide (H2S), which is extremely flammable and highly toxic. Its corrosive nature means that it can cause damage even within an industrial system, causing piping and equipment to rust and leading to further leakage and contamination.
In addition to H2S, other sulfur species such as Carbonyl Sulfide (COS), mercaptans (RSH), organic Sulfides (RSR), Sox and NOx, HCl, and HF acid gases are available in gas streams. Activated carbon has proven extremely effective at filtering out this harmful substance, especially when impregnated with metal compounds or alkali salts to neutralize acidity, and CarbUSA offers a special series of products for removing such gases eliminating health hazards as well as better use of the plant and equipment. As the products are available in normal grades, impregnated grades, and advanced catalytic grades, customers can have a wide variety of choices of products. In particular, the catalytic activated products with an H2S breakthrough capacity of 0.3g/cc give extremely efficient and economical performance increasing the life span of the absorbers, thus the downtime in the wastewater treatment plants.

Treatment of Alkali Gases – Ammonia, Sodium Hydroxide fumes, etc.

Industrial activities that need cleaning and bleaching, such as laundry and metal processing, frequently emit alkali gases such as sodium hydroxide or ammonium hydroxide, as well as other inorganic chemicals, which can harm human lungs if not filtered out throughout the process.
Maintaining this typically necessitates coating or treating other cleaning technologies used in the process with activated carbon to guarantee that such pollutants are absorbed and filtered out before they enter the environment. CarbUSA provides granulated or extruded activated carbon solutions that are further treated with other chemicals to ensure that no contaminants escape their grasp.

Solvent Recovery

Industries that utilize dyes, inks, and paints, such as dry cleaners and printing presses, rely on solvents that degrade into vapor over time. Recovering these vaporized solvents from exhaust fumes benefits both the economy and the environment; hence, the adsorption method used to filter these compounds from exhaust fumes is frequently followed by desorption to recover these chemicals for later consumption.
Different sizes and grades of activated carbon filters can be employed depending on the kind of solvent to be extracted, and CarbUSA can offer the appropriate product to guarantee your operations are both environmentally and economically sustainable.
