Abstract The factors to be considered in the design, installation and operation of a recirculation system are reviewed and discussed in this research report. The variables are: overall design; feasibility assessment; contaminant properties; exhaust cleaning; surveillance and response systems; recirculation system design; performance evaluation; maintenance and operation. The appendices, which embody the conclusions of the report, show modeling of a system, equations and calculations for the configurations, and a hypothetical system for vapour degreasing.
