Abstract
Methods and apparatus relate to treating hydrocarbons recovered with steam condensate from a formation. The treating removes particulates from the hydrocarbons by addition of a flocculant to produced fluids containing the hydrocarbons and an aqueous phase with the condensate. The flocculant causes the particulates suspended in the hydrocarbons to agglomerate and be transferred to the aqueous phase, which is then separated from the hydrocarbons.
