The primary pressure vessels in these circuits are the Heater vessel (for Heat Recovery), the Autoclave (primary reactor) and the Flash Vessel (Pressure let down). The piping systems connect these vessels to complete the circuit. An array of material is used for the various services in the autoclave circuits. Materials are selected depending on the fluid service, erosion and corrosion rates
