CPG - LF 12x40 - Acid Washed Granular Activated Carbon - Brochure

Making Water and Air Safer and Cleaner www.calgoncarbon.comPRODUCT BULLETINDescriptionCPG LF is a granular activated carbon with a low acid soluble iron content that is designed for the purification and decolorization of manyaqueous and organic liquids. It can be used efficiently in either fixedor moving beds. The particle size of 12 x 40 mesh has been selectedto give a high rate of adsorption and low resistance to flow with liquorsof medium viscosity. CPG LF is produced with virtually no fines or dust.CPG LF is made from selected grades of bituminous coal combinedwith suitable binders to give superior hardness and long life. Producedunder rigidly controlled conditions by high temperature steam activa-tion, this carbon provides high surface area, large pore volume, highdensity and a pore structure optimal for the adsorption of color bodiesand odor molecules from solution.Features• Metallurgical grade bituminous coal• Reagglomerated with binders and steam activated• Acid washed• Granular productBenefits• Produces a strongly adsorbing pore structure optimal for the adsorption of color bodies and odor molecules.• Reduces iron and ash levels so that product does not leach in acidic solutions.• Cleaner, more efficient operation than with powdered carbons.• Lowers product cost, improves product quality.• Requires less equipment to operate than with powdered carbon.ApplicationsOne of the most common uses of CPG LF is in solutions of low pHsuch as corn syrup. Since the carbon has been acid washed, the constituents of CPG LF will not be leached into the acidic solution. Furthermore, the high adsorption capacity of CPG in fixed or movingbeds permits continuous decolorizing cycles, after which the carboncan be thermally regenerated for repeated use. The advantages andeconomic benefit of CPG LF are also evident when it is used in the pu-rification of acid solutions such as muriatic and adipic.Specifications CPG LF 12x40Iodine Number 950 mg/g (min)Molasses Number 210 (min)Moisture by Weight 3% (max)Abrasion Number 78 (min)Mean Particle Diameter 1.2 - 1.4 mmAcid Soluble Iron by weight 0.01% (max)Screen Size by Weight, US Sieve SeriesOn 12 mesh 5% (max)Through 40 mesh 0.5% (max)Design ConsiderationsEconomy of column operation The use of highly active Calgon Carbon granular carbons in fixed ormoving beds provides the ultimate in countercurrent efficiency andsimplicity of operation. A properly designed system offers:• A cleaner, continuous operation• More efficient utilization of the activated carbon - more impurities adsorbed per pound of carbon• Less equipment - less floor space• Lower carbon dosage - lower costs• Improved product quality - better colors, plus odor removalCPG® LF 12x40Acid Washed Granular Activated CarbonCopyright© 2012 Calgon Carbon Corporation, all rights reserved. 1112Your local representativeCorporate HeadquartersCalgon Carbon Corporation500 Calgon Carbon DrivePittsburgh, PA USA 15205800.422.7266412.787.6700412.787.6713 Faxwww.calgoncarbon.comEuropean OperationsChemviron?Carbon?CorporationZoning?Industriel?C?de?FeluyB-7181?Feluy,?Belgium+?32?(0)?64?51?18?11+?32?(0)?64?54?15?91?Fax50%Cert no. xxx-xxx-000000Making Water and Air Safer and Cleaner www.calgoncarbon.comAsia OperationsCalgon?Carbon?Asia?Pte?Ltd.9?Temasek?Boulevard#26-02?Suntec?Tower?TwoSingapore?038989+65?6221?3500+65?6221?3554?FaxTypical Pressure DropBased on a liquid with a specific gravity of 1.2Safety MessageWet activated carbon preferentially removes oxygen from air. In closedor partially closed containers and vessels, oxygen depletion may reachhazardous levels. If workers are to enter a vessel containing carbon,appropriate sampling and work procedures for potentially low oxygenspaces should be followed, including all applicable federal and staterequirements.
