Abstract
A method for preventing or removing water soluble fouling located downstream of an oxidative dehydrogenation (ODH) reactor is described. The method employs the introduction of water upstream of fouling locations, either continuously or intermittently, which acts to solubilize and carry away fouling material. The method has the advantage of being applicable for use while an ODH process is ongoing, circumventing the need for a costly shutdown.
