An example of this firm’s development of customized spraying solutions is a recent application involving oil quenching in the production of ethylene. Ethylene feedstock is mixed with steam and heated to around 1,500°F in the pyrolysis furnace. Downstream of the furnace, the process stream must be cooled. This is accomplished by injecting oil into the process stream to reduce the temperature. The solution is a MaxiPass series of nozzles (photo), which are designed for hydrocarbon feed applications, provide good drop size and are available in a wide range of materials, including the 316L stainless steel selected for this application. — BETE Ltd., Lewes, U.K.
