Industrial Air/Gas Treatment
As the world's leading producer of granular activated carbon, related services and systems for industrial and environmental applications, Calgon Carbon offers a variety of solutions for industrial air and gas treatment. These include carbon adsorption technologies, a broad range of activated, impregnated, and pelletized carbon products, and advanced systems for solvent recovery and VOC removal and destruction.
Carbon Dioxide Treatment: Mercury Removal
Some carbon dioxide streams contain small quantities of mercury. The presence of mercury is a health and safety concern, especially for food-grade carbon dioxide. Calgon Carbon has a proven solution for mercury removal from carbon dioxide.
Carbon Dioxide Treatment: Organics Removal
Carbon dioxide (CO2) is a gas widely used in industrial and food applications. It is produced from combustion of carbonaceous fuels, from fermentation operations, and underground wells. Often there are impurities associated with CO2 production that must be removed prior to its use. The presence of organic contaminants can preclude the use of CO2 in a number of applications, but Calgon Carbon has a proven solution for organics removal.
Carbon Dioxide Treatment: Sulfur Compound Removal
Contaminated carbon dioxide (CO2) streams are encountered in industrial processes, such as fermentation off-gases, and as natural CO2 produced from wells. These CO2 streams will typically contain odorous hydrocarbons and sulfur compounds that must be removed in order to make the CO2 suitable for use. Calgon Carbon offers a variety of granular activated carbons and specialty grade impregnated activated carbons to for effective hydrocarbon and sulfur compound removal from gas streams.
Catalysts can be poisoned or fouled by low concentration organic compounds, sulfur or mercury species. Activated carbons, non-impregnated and impregnated types, are typically used as 'guard beds' to protect the catalysts (from fouling and/or deactivation) and the equipment (from corrosion) in streams such as natural gas, acetylene, ethane-propane and ethylene oxide. Calgon Carbon Corporation offers a wide range of activated carbon products suitable for catalyst protection.
Gasoline Vapor Recovery
Due to both regulatory and economic factors, the recovery of evaporated gasoline vapors during physical transfer of gasoline is required at gasoline terminal locations. Calgon Carbon offers a proven technology for gasoline vapor recovery that prevents costly product losses.
Natural Gas Treatment: Removal of Mercury
Many natural gas wellheads contain small quantities of mercury, which cause corrosion in the aluminum cryogenic exchangers used in LNG and LPG plants. In addition, mercury present in hydrocarbon gas streams will reduce the life of many precious metal catalysts. Calgon Carbon has a proven solution for the removal of mercury from natural gas.
Natural Gas Treatment: Removal of Sulfur Compounds
Natural gas feedstocks, for processes such as ammonia, methanol, and hydrogen production, contain sulfur compounds. These compounds can deactivate reforming and shift catalysts, which necessitates expensive catalyst replacement and causes a loss of production. Calgon Carbon has developed specialty impregnated grade activated carbons for the removal of sulfur compounds from inert gas streams, specifically, hydrogen sulfide and low-molecular-weight organic sulfur compounds.
In meeting regulatory standards for the removal of VOC emissions - and new imperatives for waste and cost reduction - efficient solvent recovery systems are a high priority throughout the industrial marketplace. Calgon Carbon offers proven technologies in cost-effective solvent recovery.
