GOVERNMENT - BASE CATALYSED DECHLORINATION
BCD_process

Base Catalysed Dechlorination (The BCD Process) Is a chemical reaction process that can be used for de-halogenation of a range of chlorinated persistent organic pollutants (POPs).

The BCD process involves the addition of a caustic solution to the contaminated medium containing one or more halogenated or non-halogenated organic contaminant compounds. A proprietary catalyst compound is also required. The mixture is heated at a temperature suitable for the reaction to take place.

The BCD process is capable of treating high concentration POPs oils and even solids up to about 40% POPs content however BCD primarily utilise the process on lower concentration PCB contaminated oils. BCD use the process to reduce PCB concentrations in transformer oils from up to 10000 mg/kg to below detectable limits. The process must be monitored to ensure that the reaction continues to completion.

Given that the process is a batch operation, it is possible to allow the reaction to proceed until the required level of destruction has been confirmed; typically batches are treated to less than 2 ppm residual PCB concentration as per Australian requirements under the National PCB Management Plan 2003 and the relevant state Acts and Regulations.
