Site visit Vist to COVEX, S.A COVEX, S.A. Implemented BAT • Environmental, safety and health aspects to be integrated within the process: • Replace substances by less-dangerous ones. • Process safety and prevention of non-controlled reactions: • Assess safety under normal operating conditions and take into account those deviations due to chemical variation and operation conditions. • Apply procedures and measures to limit the risk associated to hazardous substances use and handling. • Provide staff with appropriate training to handle hazardous substances. Slide 5
Site visit Vist to COVEX, S.A COVEX, S.A. • Plant design: • Install laminar flow pumps in reactors starting point • Closure of PQIII reactor building. • Condensation equipment in all production units. • Soil and groundwater protection: • Design, build and maintain installation (sealed, stable and resilient against mechanical thermal and chemical)in order to minimize spills • Implement in situ leak detectors. • Install leak and spill retention containers for further treatment and disposal. Slide 6
Site visit Vist to COVEX, S.A COVEX, S.A. Implemented BAT • VOC reduction: • Contain and seal any source to minimize diffuse and non-controlled emissions. • Dry by using close-circuits and include condensation equipments to recover solvents. • Maintain closed any equipment when proceeding with the cleaning of solvent containers. • Recirculation of process vapors when concentration requirements allow. Slide 7
Site visit Vist to COVEX, S.A COVEX, S.A. Implemented BAT • Reduce waste gas flows: • Ensure that equipments are hermetic, specially reactors. • Minimize waste gas flows in distillation, optimizing condensation design. • Apply liquid feeding at the bottom of the reactor, unless a chemical reaction advices against, to reduce COT values in waste gas. • Minimize peak loads by optimizing production patterns and ad hoc filters. Slide 8
Site visit Vist to COVEX, S.A COVEX, S.A. Implemented BAT • Minimize volumes and waste water pollution charge: • Avoid discharges of main solution with high salt content or applied separation techniques: process membranes, reactants extraction, solvent-based processes. • Mass balance and waste water sampling: • Establish mass balances for VOC, TOC, COD, AOX and metals to better understand processes and implement improvements. • Undertake a detailed analysis of the waste water stream in order to identify origins and prepare basic data to handle and treat waste gas emissions, waste water and solid wastes. Slide 9
