| Project Abstract | This galvanising company will change the production process to convert from dry fluxing to hot wet fluxing with chemical recycling. Aspects of the new production process include: Continuous recycling of flux treatment to reduce dross formation; Product for galvanising will be pre-cleaned to prevent contamination of the recycling process; Hot dry product will reduce zinc consumption by reducing oxide formation at source with less skimmings and fume; Engineered furnace flue gas heat recovery will be introduced and All pre-treatment processes will take place in enclosed spaces. Environmental benefits: The source of fugitive emissions arising from vaporised flux and water will be reduced; Galvanising mud from dirty incoming product will no longer cause fume or skimmings formation on the zinc pot surface; There will be a reduction in zinc contamination of all aspects of the process; There will be downstream savings in chemicals and energy used in recycling lesser quantities of skimmimgs and dross; Heat recovery will reduce carbon dioxide emissions; Reduced energy and water consumption over conventional wet fluxing and No new emissions to sewer. Economic benefits: There will be reduced chemical costs as it is anticipated that there will be less waste of flux due to more precise application; There will be reduced energy costs arising from heat recovery; Zinc consumption will be reduced. It is expected that the greatest economic benefits will be achieved on lower zinc waste; The new process will provide the opportunity to improve quality and consistency of product. This will also reduce re-work and There will be an improvement in safety aspects of the operation. |
