Understanding Process Additives – Innovations in Oilfield, Refining ...

In a great number of industrial settings, one of the continuous challenges is to maintain equipment that is clean and free of deposits. A common adversary is that oilfields, refineries, and chemical plants all have to contend with fouling. To put it another way, this is the technical word for the accumulation of undesirable organic compounds such as asphaltenes. In the absence of any intervention, this process has the potential to reduce efficiency and raise operational costs drastically.
