Liquid Chemical Applications With an extensive range of coal, coconut, granular, powdered and high purity acid washed activated carbons, Chemviron Carbon have a solution for a host of purification challenges, for industries producing or using liquid chemicals. If the process is batch or continuous, Chemviron Carbon will apply expertise, through targeted assessment, laboratory and pilot trialling to select the appropriate carbon. Isotherms trials, to provide indicative carbon selection and usage, can be conducted in our extensive laboratories. For more prescriptive performance information we can supply mobile equipment ranging in size from 20l to 20m3, and indeed supervise, pilot and full scale production trials. This information, when evaluated by our experienced Applications Engineers, proves to be invaluable in identifying the most efficient solution for the challenge. Removal of Colour and/or Colour Forming CompoundsChemviron Carbon has a range of carbons proven as successful carbons for use in many liquid chemical de-colour applications. The range are, cost effective, high quality and reliable carbons that have excellent de-colour performance and ease of use. The inherent properties of our powder and granular carbons provide customers with superb performance for colour removal from a range of liquid chemicals including:
Removal of Corrosive ImpuritiesScrubber liquid Purification - Amine solvents such as Diethanolamine (DEA) are widely used in recirculating loops to remove Carbon Dioxide (CO2) and Hydrogen Sulphide (H2S) from natural gas. Granular activated carbon is installed to purify the recirculating amine to remove degradation products and dissolved hydrocarbons. Chemviron Carbon supply the Cleanamine range of standard adsorption systems for amine purification. Some of the benefits of using this technology include:
Other solvents that can also be purified for corrosive compound removal include:
Removal of Mercury in Chloralkali IndustryCaustic Soda is used extensively in, and is also a by-product from, the chloralkali industry. Mercury cells are used for production of chlorine, hydrogen, and sodium (in a few plants potassium) hydroxides by electrolysis of a brine solution, and this can cause contamination. Chemviron carbon has a range of steam activated and impregnated carbons that are proven for this application. Removal of Metal Finishing Residues and Trace OrganicsOver a period of time electroplating chemicals become contaminated with organics and metal finishing residues. An effective method of removal is through the use of steam activated carbon, allowing the chemicals to be re-circulated for re-use. Chemviron Carbon has a range of steam activated carbons that have been proven to provide superior efficiency in this application.
In addition activated carbon has also been used for the removal and recovery of chromium in Electroplating Solutions. Removal of Organic MatterA number of liquid chemical product and by-products also become contaminated by organic compounds. In order to ensure these products are suitable for sale or re-use different grades of activated carbon can be used. Chemviron Carbon have a range of standard and acid washed carbons that are suitable for purification of chemicals including:
