Method of recovering heat transfer in reactor and regenerator effluent coolers

摘要

This invention relates to a method for removing fouling from a heat transfer surface, such as a heat exchanger. The method involves conducting a vapor containing a scouring material to the heat transfer surface and contacting the scouring material with the foulant, the heat transfer surface, or both. Scouring material and removed foulant can be recovered and conducted away.
