Abstract
A method for mitigating fouling in a once-through steam generator train is described. The method involves obtaining foulant samples from the once-through steam generator train. Obtaining water samples from one or more locations along the once-through steam generator train. Recovering filtered solids from the water samples from the one or more locations. Characterizing at least one physical property of the foulant samples and the filtered solids. Determining locations along the once-through steam generator train that include foulant precursor based on a matching of the at least one physical property between the foulant samples and the filtered solids. Installing an absorbent at locations that include the foulant precursor.
