Collection, disposal, and treatment systems are an integral part of pressure relief systems for minimizing potential hazards posed by the effluent from pressure relief devices. There are several strategies for effluent handling, as well as common unit operations for executing those strategies in design, including knockout drums and flares. 

The design and analysis of effluent handling systems should address the primary goals of ensuring safe operation of relief devices and equipment tied to the system as well as appropriate design of the collection system piping and effluent handling equipment, and a heuristic for the analysis of effluent handling systems is provided to address these goals.
