6.1 Site Services and Disposal

Removal service - emptying of solvent recovery adsorbers

To simplify the operation of an adsorption system, the Site Services Division of CPL Carbon Link is able to provide a comprehensive media handling package, including the supply of all necessary labour and equipment to undertake the required work.

This service extends beyond the handling of the media to repairs to adsorption equipment and process appraisal to assess the operation of individual facilities. A team of highly experienced operators are used offering flexibility to meet site requirements.

Filling Service - This work is generally undertaken using high power water jet eductors to pump a slurry of water and activated carbon into the adsorption system. This method offers the benefits of being simple to operate, minimising attrition products and assisting in commissioning procedures.

Removal Service - This process is often considered both difficult and laborious involving the use of significant numbers of man hours for even the smallest filtration systems. CPL Carbon Link undertake this operation using high volume, air conveying equipment designed for the transportation of granular products. The system provides the facility for the transfer of spent adsorbent into a variety of bulk containers to assist in the easy removal from site.

Often, the removed spent product will be returned for reactivation and this is easily undertaken by CPL Carbon Link, involving the completion of all necessary documentation. However, in some cases reactivation is not a viable alternative and the material must be disposed of in a responsible and environmentally sensitive manner.

CPL Carbon Link offers the unique opportunity of using the intrinsic calorific value of the spent adsorbent as a secondary or waste derived fuel. The spent material is blended with waste organic solvent to produce a specific fuel mixture. This is then used as a substitute for coal to fire an industrial kiln process for cement production. This provides a valuable source of energy wile reducing the need for depletion of a natural resource.

This service is offered in accordance with the Special Waste Regulations 1996 - Section 62.

Activated carbons saturated with a wide range of organic compounds can be dealt with using this technique. Hydrocarbon solvents Halogenated solvents Organic sulphur compounds Phenols and chlorinated phenols Organic acids Alcohols, ketones, amines, esters Specialist advice is readily available to assist you with your specific requirements.
