ABSTRACT OF THE DISCLOSURE Oil gas separation Polysiloxanes of specified molecular weight and molecular weight distribution are effective anti-foam agents for reducing foaming in crude oil/gas separators. They are particularly useful in breaking microgas dispersions. The polysiloxanes, preferably polydimethyl siloxane, contain not more than 10% by weight of components of molecular weight 50,000 and lower, at least 15% by weight of components of molecular weight 200,000 and higher and not more than 6% by weight of components of molecular weight 370,000 and higher, molecular weights being expressed as polystyrene equivalent molecular weights.
